Forged Elbow Butt Pipe Fittings Carbon Steel Butt Pipe Fittings 90 Degree Elbow Seamless
The basic process of carbon steel elbows is: firstly weld a polygonal ring shell with a polygonal cross section or a polygonal sector shell with closed ends. After the interior is filled with pressure medium, internal pressure is applied, and the cross section is cross-sectioned under internal pressure. From a polygon to a circle, it eventually becomes a circular ring shell. According to needs, a circular ring shell can be cut into 4 90° elbows or 6 60° elbows or other specifications of elbows. This process is suitable for manufacturing any elbow whose pitch diameter to inner diameter ratio is greater than 1.5 Large size elbows are an ideal method for manufacturing large carbon steel elbows.
The advantages of the carbon steel elbow manufacturing process are mainly manifested in the following aspects:
(1) Tube blanks are not needed as raw materials, which can save tube-making equipment and mold costs, and can obtain arbitrarily large diameter and relatively thin carbon steel elbows.
(2) The blank is a flat plate or a developable curved surface, so the blanking is simple, the accuracy is easy to ensure, and the assembly and welding are convenient.
(3) Due to the above two reasons, the manufacturing cycle can be shortened, and the production cost is greatly reduced. Because it does not require any special equipment, it is especially suitable for on-site processing of large carbon steel elbows.
(4) Carbon steel elbows are suitable for pipeline series in oil, natural gas, chemical, hydropower, construction and boiler industries.
