The difference between rolled steel plate and spiral steel pipe produced by strip production

The coiled sheet refers to the steel plate whose width of the raw material of the spiral steel pipe is greater than or equal to 1500mm, while the strip steel refers to the steel plate whose width is less than 1500mm. These two raw materials can produce the API 5L Large Diameter Welded Spiral Steel Pipe. The main differences between the spiral steel pipe produced by the two raw materials are as follows:

　　1. In terms of price, because the price of coil plate with the same thickness is higher than that of strip steel, the production of spiral steel pipe coil plate is also higher than that of strip steel.

　　2. In terms of quality, the compressive strength of spiral steel pipe produced by coiled sheet is greater than that of spiral steel pipe produced by strip steel because of the large pitch of spiral steel pipe produced by coiled sheet.

　　3. Appearance, because of the large pitch of spiral steel pipe produced by coiled sheet, the inclination angle is also large, and the production is more beautiful. There is basically no angle in narrow strip production.

　　4. the service life of spiral steel pipe produced by coil production is longer than that of spiral steel pipe produced by strip production.

　　5. Matching pipe fittings, the general standard of matching pipe fittings requires the use of spiral steel pipe produced by coiled sheets to act as raw materials.
