Carbon steel pipe fittings
What is carbon steel pipe fitting?
Carbon steel pipe fitting is one of the most widely used pipe fitting products. The main material is Q235,20#,35#,45#, 16Mn. The main products include carbon steel elbow, carbon steel flange, carbon steel tee, carbon steel tee, carbon steel reducing pipe (size head), carbon steel head (cap) and so on. The main implementation standards include national standard, American standard, Japanese standard, which also includes the Ministry of Chemical industry standards, Sinopec pipe fitting standards, power pipe fitting standards.
Carbon steel pipe fittings basic process:
First of all, welding a polygonal cross section of the polygonal ring shell or the two ends of the closed polygonal fan shell, internal pressure after the internal pressure medium, under the action of the cross section from polygon gradually into a circle, eventually become a circular ring shell. According to the need, a round ring shell can be cut into a bend or a bend or other specifications of the elbow, the process is suitable for manufacturing elbow middle diameter and elbow inner diameter ratio is greater than. Any size of large elbow, is currently the ideal way to manufacture large pressure elbow.
The advantages of carbon steel pipe fittings are mainly shown in the following aspects:
- The cost of pipe equipment and die can be saved without pipe billet as raw material, and the elbow with any large diameter and relatively thin wall thickness can be obtained。
- The blank is flat or developable surface, so the blanking is simple, the precision is easy to ensure, and the assembly and welding are convenient.
- Because of the above two reasons, the manufacturing cycle can be shortened and the production cost can be greatly reduced. Because it does not need any special equipment, especially suitable for the field processing of large elbow. The technology has been applied for national invention patent.
