Basic technology of carbon steel pipe elbows

The basic manufacturing process for carbon steel pipe elbows is as follows: First, polygonal annular shells or polygonal sector shells sealed at both ends are welded together. After filling the interior with a pressure medium, internal pressure is applied. Under the action of internal pressure, the cross-section gradually changes from polygonal to circular, eventually forming a circular annular shell. As needed, the circular annular shell can be cut into four 90-degree elbows, six 60-degree elbows, or other specifications of elbows. This process is suitable for manufacturing large elbows of various specifications with a pitch circle diameter to inner diamete
