The advantage of the carbon steel elbow production process mainly in the following aspects

　　The basic process of carbon steel elbow is: First welding a polygonal cross-section polygonal ring shell or shell closed at both ends of the polygonal sector, washed over the internal pressure of the medium, the pressure applied within the inner cross-section under Pressure polygon gradually become round, eventually becoming a circular ring shells. If necessary, a circular ring shell can be cut four or six 90 ° elbow 60 ° elbow or other specifications of the elbow, the process for the manufacture of bend in any ratio greater than 1.5 times the diameter of the inner diameter and elbow specifications large elbow, is an ideal method of manufacture of large carbon steel elbow.

　　The advantage of the carbon steel elbow production process mainly in the following aspects:

　　(1) without tube as raw materials, saving pipe equipment and tooling costs, and the large diameter and wall thickness can be obtained at any of the relatively thin carbon steel elbow.

　　(2) the blank is flat or developable surface, thus cutting simple, easy to ensure accuracy, easy assembly and welding.

　　(3) Due to the above two reasons, it can shorten the manufacturing cycle, the production cost is greatly reduced. Because does not require any special equipment, it is particularly suitable for on-site processing of large carbon steel elbow.

　　(4) carbon steel elbow for petroleum, natural gas, chemicals, utilities, construction and boiler piping industry series.

　　We have adopted advanced production equipment and technologies to manufacture our pipe bend and steel butt welded tee, which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.
