The advantage of the steel elbow

　　(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.
