　Low-pressure fluid transmission with welded steel pipe (GB / T3092-1993), also known as the general pipe, commonly known as ASTM A790 Welded Steel Pipe Manufacturer. Is used for conveying water, gas, air, oil and heating steam and other general low pressure fluid and other uses of welded steel pipe. Steel pipe wall thickness is divided into ordinary steel pipe and thickened pipe; take the end of the form is divided into non-threaded steel pipe (light pipe) and welded steel pipe. The specifications of the steel pipe are denoted by nominal caliber (mm), and the nominal caliber is an approximation of the inner diameter. Used to use in inches, such as 11/2 and so on. Low pressure fluid delivery welding pipe in addition to direct use for the transport of fluid, but also a large number of low-pressure fluid for the use of galvanized welded steel pipe of the original pipe.
