Price is not the only criterion for selecting cast steel shots

 In recent years, some enterprises have experienced performance decline, wage arrears, bankruptcy and other phenomena, including some large enterprises. Some enterprises have been losing money this year, relying on the continuous closure of stores to control the extent of losses. What causes this situation?
  Due to the serious overcapacity in China, the state has more strict control over the cast steel shot industry. At present, many Cast Steel Shot For S230 manufacturers either do not have orders, or rely on very low profits to maintain their operations. In addition to the external environment, the intrinsic vicious competition makes enterprises already in deep water more difficult. In order to maintain customers, in order to have business to do, some enterprises at all costs or even lose money to sell goods. In this case, large enterprises can bear the pain, and small and medium-sized enterprises can only be slaughtered.
  In the buying and selling market, as long as the buyer meets the specifications, regardless of the quality, try to buy cheaply. In order to make profits, some steel ball manufacturers have to reduce their costs as much as possible. By adopting raw materials with poor quality and shortening process flow, the cast steel shot produced can not meet the national standard. And those who want to produce high quality steel pills and establish good brands will have difficulty in operating in this morbid market. Gradually, some manufacturers will drift with the tide, while others will slowly disappear.
  So don't be complacent about buying low-priced products. They all have certain production costs. The correct way for enterprises to grow up is to adjust the price of cast steel shot properly on the basis of ensuring the quality of products.

Main application scope of cast steel grits

 1. Workpiece coating and cast steel grits before bonding can remove all dirt such as rust on the workpiece surface, and establish a very important basic schematic on the workpiece surface. Moreover, abrasives of different particle sizes can be exchanged.
  2. The cleaning and polishing of cast steel grits and workpiece after heat treatment and sandblasting can clean all the dirt on the surface of cast steel grits and workpiece after heat treatment, and Cast Steel Grits G80 for Shot Peening surface to improve the cleanliness of workpiece, which can make the workpiece show uniform and consistent metal nature, and make the workpiece appearance more beautiful and beautiful.
  3. Burr cleaning and surface beautification cast steel grits of machined parts can clean up the micro-burrs on the surface of the workpiece, make the surface of the workpiece smoother, eliminate the hazards of burrs, and improve the grade of the workpiece.
  4. Cast steel grits with improved mechanical properties can produce uniform and fine concave and convex surfaces on the surface of parts, which can store lubricating oil, improve lubrication conditions, reduce noise and improve the service life of machinery.
  5. For some special purpose workpieces, cast steel grits can achieve different reflections or matte at will. Such as polishing of stainless steel workpiece, plastic, polishing of jade, matting of wood furniture surface, pattern of polished glass surface, and texturing of cloth surface, etc.

The hardness of cut wire shot is determined by carbon content

To ensure the quality of cut wire shot, the carbon content of cut wire shot determines the hardness and quality of cut wire shot.
  After quenching and heating, there are two kinds of cooling methods for steel. One is isothermal cooling,isothermal quenching, and the other is continuous cooling,ordinary quenching. Pearlite, sorbite, toxite and bainite can be obtained by isothermal cooling as required, while martensite can be obtained by ordinary quenching. All kinds of Carbon Steel Cut Wire Shot, mechanical parts and moulds are used after quenching and tempering. The strengthening and hardening occur during quenching is due to the formation of martensite.
  There are two basic forms of martensite. Although the carbon content determines the form of martensite, we can adjust the process to maximize the performance of the workpiece. The hardenability of cut wire shot is poor. Therefore, almost all lath martensite can be obtained by intensive quenching, and a good combination of higher strength and toughness can be obtained. Medium carbon steel or medium carbon alloy steel are widely used steels. Their carbon content ranges from 0.2% to 1.0%. The mixed structure of lath martensite and lamellar martensite is formed by quenching. When these steels are heated and quenched at high temperature, more lath martensite can be obtained, and the toughness of the steel can be greatly improved with the same hardness. For high carbon steel, in order to obtain more lath martensite, the method of heating and quenching at lower temperature and in short time can be adopted.

Cast steel shot is a kind of abrasive with good surface cleaning effect

Cast steel shot is a kind of abrasive with good surface cleaning effect. The hardness of cast steel shot determines the service life of cast steel shot. The hardness of cast steel shot is proportional to the cleaning speed. The higher the hardness, the faster the cleaning speed, the consumption of cast steel shot, the shorter the service life, and the manufacturing process of cast steel shot determines the size of Cast Steel Shot For S660. The bigger the diameter is, the higher the surface roughness will be, but the work efficiency is also very high, and the wear of steel shot is also larger.
  The cost of cast steel shot determines the company's cost-effectiveness, the choice of cast steel shot, the hardness should be moderate, the size should be uniform, such specifications can extend the service life. These are the characteristics of Hebei Reaguan cast steel shot. Of course, when used with appropriate equipment, Hebei Reaguan cast steel shots are the best abrasives for surface cleaning because of their durability.
  Surface treatment of metal workpieces has the characteristics of fast cleaning speed, proper hardness of cast steel shot, good rebound elasticity, inner corner and complex shape of workpieces can be cleaned uniformly and quickly, shorten the time of surface treatment, improve work efficiency is a good surface treatment material.
  Cast steel shot is a commonly used surface treatment material. There are many kinds of cast steel shot. The raw materials and equipment for different kinds of cast steel shot are also different.

Major causes of deterioration of bend quality

 1. In pure bending, under the action of external force distance, the outer arm wall of the neutral layer is thinned by tension stress, while the inner arm wall is under compression stress. Thickening due to action, combined force changes the cross section of the pipe. Based on this factor, the main reason for the decline of bend quality is that the value under various pressure levels and the outer thinning are clearly defined, so as to ensure the quality.
  2. When 4 inch carbon steel 45 degree 5D large radius bend, the material is pulled on the outside and the neutral axis under internal pressure is different from the bending method. When bending the pipe, the neutral axis is about 1/3 away from the outer wall. When bending the pipe, the neutral axis is about 2/3 away from the outer wall. Therefore, it is beneficial to use rotary bending method for thin-walled pipe bend.
  3. The precision of bend is also one of the factors affecting the quality of pipe bend. In the manufacture of bending tyres, besides the requirement of specifications and sizes to be controlled within a certain tolerance range, users are also required to select the corresponding bending tyres according to the diameter of the bend pipe.
  4. The bendability and surface corrosion of the pipe itself may also affect the quality of the bend. In site construction, operators also need to know the material of the pipe bend processed, the processing performance and the production judgment of the surface corrosion.

What are the main types of spiral steel pipe production line?

  Spiral steel pipe are commonly used for survival, but few people know the key categories of spiral steel pipe production lines.
  1. Single Chain Cold Bed
  Climbing structure is often used in single-chain cold bed. The cold bed is composed of forward transport chain and invariable guide rail, and has a set of transmission system. The ASTM A53 SSAW Sch 40 Spiral Steel Pipe is placed between the two pulling grasps of the forward transport chain, and the guideway bears the weight of the spiral steel pipe body.
  2. Double Chain Cold Bed
  The double-chain cold bed consists of forward and reverse transport chains, each of which has a transmission system. The spiral steel pipe is placed between two pulls of the forward transport chain, and the reverse chain bears the weight of the spiral steel pipe body.
  3. New Chain Cooling Bed
  Combining the characteristics of single-chain cold bed and double-chain cold bed, the cold bed is divided into uphill section and downhill section. Uphill section is a double-chain structure consisting of forward and reverse transport chains. The positive and negative interaction makes the steel pipe continue to rotate and move forward and do climbing activities.
  4. Stepping rack type cold bed
  The stepping rack type cold bed bed is composed of two groups of racks. One is mounted on the invariable beam, which is called static rack. The other is mounted on the moving beam, which is called moving rack. When lifting the organization behavior, the moving rack lifts the spiral steel pipe. Because of the skew angle, the steel pipe rolls along the tooth shape once when lifted.
  5. Screw type cold bed
  The screw cooling is composed of a main transmission device, a screw and a constant cooling bench. The screw comprises a screw core and a screw helix. The working surface of the invariable cooling bench is higher than that of the spiral rod core and lower than that of the spiral steel pipe. The weight of the steel tube body is borne by the invariable cooling bench.

Pipe fittings socket outlet is widely used

Pipe fittings socket outlet is a kind of branch pipe platform which has been widely used in foreign countries in recent years. A105 Forged Cl6000 Pipe Fittings Socket Outlet is a kind of reinforcing pipe fittings used for branch pipe connection. It replaces the traditional branch pipe connection types such as different diameter tee, reinforcing plate and reinforcing pipe section.Pipe fittings socket outlet has the outstanding advantages of safety and reliability, low cost, simple construction, improvement of medium flow channel, series standardization, convenient design and selection, especially in high pressure, high temperature and large scale. Pipe fittings socket outlet is used more and more widely, replacing the traditional branch pipe connection method.
  The main body of the branch pipe platform is made of high quality forgings with the same material as the pipeline, such as carbon steel, alloy steel, stainless steel, etc. The branch pipe and the main pipe are welded. There are butt welding, socket welding, threading and other types of connection between the branch pipe platform and the branch pipe or other pipes, instruments and valves. Standards: MSS SP 97, GB/T 19326, Pressure: 3000#, 6000#.

Notes for pipe fitting stainless steel elbow

1. When installing, pipe fitting stainless steel elbow can be directly installed on the pipeline in connection mode and installed in accordance with the position used. Generally,pipe fitting stainless steel elbow can be installed in any position of the pipeline, but ASTM A403 WP304L Large Caliber Pipe Fitting Stainless Steel Elbow needs sealing to prevent leakage and affect the normal operation of the pipeline.
  2. Ball valves, globe valves and gate valves with pipe fitting stainless steel elbow should be fully opened or closed only when used. Flow regulation is not allowed to be used to avoid sealing.
  3. The long-term storage of pipe fitting stainless steel elbow should be inspected on time. The exposed processing surfaces should be kept clean, dirt removed, neatly stored in indoor ventilated and dry places, and stacking or open storage are strictly prohibited. Pipe fitting stainless steel elbow are often kept dry and ventilated. Keepers are clean and tidy and stored in accordance with accurate storage methods.
  Pipe fitting stainless steel elbow need to pay attention to a lot of things, users need to use in accordance with certain methods, in accordance with accurate and fair methods of use and maintenance.

Polishing technology of stainless steel special pipeline cap

The polishing process of stainless steel special pipeline cap is introduced. The middle polishing wheel is used to further process rough polished surface. Stainless steel special pipeline cap can remove scratches left by rough polishing and produce smooth to medium bright surface.ASTM B16.9 A403 WP304 Stainless Steel Special Pipeline Cap surface roughness ranges from zero to several microns.
  Rough polishing is used to grind, polish or grind the head surface with hard wheels. Therefore, rough polishing is also called grinding or polishing. Stainless steel special pipeline cap is mainly used to remove burrs, scratches, rust marks, oxide scales, sand holes, bubbles, welding nodules, welding slag and various macro defects on the surface of parts, in order to improve surface smoothness and reduce surface roughness.
  Fine polishing is the last process of polishing stainless steel special pipeline cap. It is a method to process the surface of parts with soft wheels coated with polishing paste. Because stainless steel special pipeline cap is carried out on a relatively flat surface, the roughness of the surface can be further reduced to achieve the purpose of micro-leveling, so a very bright surface can be obtained. Moreover, there is no obvious wear on the substrate when the head is polished, and the surface roughness can reach about 0.01 um, which can truly achieve the mirror brightness.

Phosphating Technology of Seamless Steel Pipe

Seamless steel pipe is a kind of steel pipe which is subdivided according to the production mode of steel pipe. The well-known production mode is to crimp the pressed steel sheet, make it tubular, and weld the combination at the bending joint. The most obvious feature of this kind of seamless steel pipe is the visible weld seam on the surface. So what are the common uses of this kind of welded steel pipe?
  Firstly, ASTM A106 Gr.B High Quality Carbon Seamless Steel Pipe is transported with the same fluid as other steel pipes. But due to the special weld seam problem of seamless steel pipe, seamless steel pipe is mostly transported with low pressure fluid. Not only the welding process affects the actual use of steel pipe and the goods transported, but also the steel plate selected for seamless steel pipe determines the use of welded steel pipe.
  Of course, for the pipeline transportation path, the size of diameter and its use is also a great relationship. Large diameter type of seamless steel pipe is more widely used in urban sewage transportation. Seamless steel tubes with smaller diameters are used to blow oxygen to steelmaking.
  Phosphating process of precise seamless steel pipes. Principle of Phosphating of precise seamless steel pipes. Phosphating process of precise seamless steel pipes is that phosphating parts are immersed in phosphating solution and deposited on the surface to form a crystalline phosphate conversion film insoluble in water, which is called phosphating.

Heat resistance of carbon steel slip on flange

1. High impact resistance: Because of En1092-B1 Carbon Steel Slip on Flange impact strength function, the ring stiffness is 1.3 times as much as that of other solid-wall tubes.
  2. Long service life: Under rated operating temperature and pressure, the service life of carbon steel slip on flange is over 50 years, with anti-ultraviolet, anti-radiation, so that the product will never fade.
  3. Good corrosion resistance: Except a few hydrogenating agents,carbon steel slip on flange can resist the corrosion of various chemical mediums. The carbon steel slip on flange has excellent acid resistance, alkali resistance, corrosion resistance, no rust, no corrosion, no bacteria, no electrochemical corrosion.
  4. Good thermal insulation: PP-R pipe has good thermal insulation because of its low thermal conductivity, the thermal conductivity of 20 degrees Celsius is 0.21-0.24W/mk, which is much smaller than that of steel pipe (43-52W/mk) and purple steel pipe (333W/mk).

Market analysis of threaded flange

 Recently, the price of threaded flanges is very low. Some steel mills and material yards intend to leave the market on holiday. The price of threaded flanges is intentionally and crazily depressed. The market in East China has fallen so badly. At present, the price of threaded flanges has fallen by about 30 percent, and the actual price of some factories that have not yet fallen outside has already been lowered by about 50 percent. Nowadays, the behavior of bull bears is becoming more and more active.
  On the market of threaded flanges, except for a short rise at the opening of last night's trading, the whole day showed a narrow cross-section trend, the average price slightly declined, the market carrying capacity gradually weakened, and the fluctuation of the last market began to decline and unified, and closed at a sub-low point. Unlike the previous days, the whole day of the day showed a continuous increase in warehouses, but the overall extent was not large, and the concentrated decline of the tail was achieved by reducing warehouses. A182 F316/316L Stainless Steel Threaded Flange seems that short-selling is still more cautious, mainly with tentative guidance, and continued development is not conducive to bulls.
  In the peripheral market, the price adjustment was weak, ranging from 10 yuan, with large household shipments of 200-1000 tons. At present, the price of construction steel in Beijing has fallen to the lowest level in the whole country, and the market transaction price is approaching the 2200 yuan/ton mark. Some businessmen also say that the market is more transparent and the phenomenon of follow-up drop is more common. A sharp reduction in the price will only lower the overall level, and will not have price advantages.
  However, the downstream demand is not good, and the steel mill price limit is pressing step by step. Considering the difficulty of high-price shipment, businessmen are facing difficulties. Bidding is in a dilemma, even the winter reserve goods have to stay on the sidelines because of the market downturn. Spot, the domestic power coal market is running smoothly, and the threaded flanges turnover is very low. As for pithead, the inadequate start-up rate of several major coal-producing areas, together with a series of production restriction measures introduced by some major coal-producing provinces, will lead to a certain reduction in production, which will also have a certain impact on the market.

Forming classification of elbow screw pipe fitting

 Elbow screw pipe fitting is a kind of elbow made by hot-pressing technology and a kind of pipe fittings. Normalizing can eliminate the net cementite of hypereutectoid elbow screw pipe fitting. For hypoeutectoid elbow screw pipe fitting, normalizing can refine the crystal lattice and improve the comprehensive mechanical properties. It is more economical to replace quenching process with normalizing for elbow with low requirement.
  Hot Push Forming
  Casting Stainless Steel 90 Degree Elbow Screw Pipe Fitting forming process is a process of heating, expanding and bending the blank on the die by special elbow pusher, core die and heating device.
  The deformation characteristics of elbow screw pipe fitting are to determine the diameter of tube billet according to the rule that the volume of metal material remains unchanged before and after plastic deformation. The diameter of tube billet used is smaller than the diameter of elbow screw pipe fitting. The deformation process of billet is controlled by the core die, so that the metal flow compressed at the inner arc is compensated to other parts which are thinned due to the expansion of diameter, and the elbow screw pipe fitting with uniform wall thickness is obtained.
  Elbow screw pipe fitting forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, which is suitable for mass production. It has become the main forming method of elbow screw pipe fitting, and also applied to the forming of elbow screw pipe fitting of some specifications.
  The heating modes in the forming process include medium or high frequency induction heating, flame heating and reflex furnace heating. The heating mode depends on the product requirements and energy consumption.

Introduction of weld outlet

The weld outlet is also called the branch pipe seat, saddle seat and saddle pipe joint. The reinforcing pipe fittings mainly used for branch pipe connection instead of using different diameter tees, reinforcing plates and strengthening pipe sections have outstanding advantages such as safety, reliability, cost reduction, simple construction, improvement of medium runner, series standardization, Schedule 40 Pipe Fittings Butt Weld Outlet, especially in high pressure, high temperature, large caliber and weld outlet, which are increasingly widely used, replacing the traditional branch pipe connection. Connection method.
  The main body of the weld outlet is made of high quality forgings with the same material as the pipeline, such as carbon steel, alloy steel, stainless steel, etc. The butt welding connection, socket welding connection and threaded connection are used to connect the support pipe with weld outlet or other pipes, meters and valves. There are MSS SP-97, GB/T19326 and other standards commonly used in the manufacture and execution of branch desks.
  Hebei Shengtian Pipe Fittings Group Co., Ltd. specializes in the production of various pipe fittings. Welcome to visit the factory.

Advantages of pipe union

1. Pipe union strength is high: According to the principle of cold work hardening of steel, the strength of straight threads rolled on steel bars is greatly increased, so that the tensile strength of straight threaded pipe union is higher than that of steel bars.
  2. Stable performance: The connection process of Standard Forged Female Thread Pipe Union is not affected by the quality of workers, so stable performance.
  3. Fast connection speed: Because of the way of out-of-site prefabrication and on-site assembly and connection, the prefabricated pipe union can have a large amount of prefabricated reserves in the steel bar stacking yard. When the construction period is tight, only additional assembly workers are needed at the construction site.
  4. Wide range of applications: There are basically no restrictions on the application of the model, and it is more suitable for the platform where the bending pipe union, the fixed steel bar, the reinforcing cage and other reinforcing bars can not rotate.
  5. Easy to manage: there will be no mismatch between sleeve and reinforcing bar, and inspection is more convenient. The operation is simple, and the ordinary worker can become a skilled worker after several hours of study.
  6. Significant economic and social benefits: shortening construction period, improving project quality, reducing energy consumption, conducive to environmental protection, reducing equipment investment, low additional costs, with obvious economic and social benefits.
  7. Low labor intensity: Processing a silk head only needs one step to complete on a special rolling machine.

How to control the branch direction of carbon steel tee?

The development trend of carbon steel tee is related to the development trend of electronic information technology. Generally speaking, the development trend of electronic instruments can be easily divided into three links: the first link is the electromagnetic induction dashboard link, DN450 Seamless BW Pipe Fitting 18" Carbon Steel Tee which has just begun to be used since the problem of electromagnetic induction was discovered, and instruments and instruments have to be measured so far. The industry has a foothold.
  The accurate measurement of carbon steel tee pair power consumption is based on the electromagnetic induction method to obtain the offset matched by the accurate measurement. The typical dashboard of this link is the electromagnetic induction galvanometer, carbon steel tee which is based on the rotating force of the current through the electromagnetic coil in the electromagnetic field, and the size of the current is expressed by the deflection of a needle driven by this force.
  Therefore, on the carbon steel tee, the size of the needle deflection can reflect the size of the current passing through the electromagnetic coil. Basically, in the electromagnetic induction galvanometer, according to converting other quantities into current, we can accurately measure other quantities of electricity, such as converting working voltage into current according to resistor, we can turn carbon steel tee into voltmeter, and converting frequency into current according to different impedance of capacitor to different frequency characteristics. And carry out accurate frequency measurement and so on.
