ASTM A403 WP304 S 90DEG LR Elbow SS SEAMLESS Change Pipeline Direction
Overwiew:
Seamless elbow is a kind of pipe fitting used in the bend of the pipeline. In the pipeline system more than the use of all pipe fittings， the largest proportion， about 80%. Usually， different forming processes are selected for elbows of different material cargo wall thickness. Manufacturing plants commonly used seamless elbow forming process are hot push， stamping， extrusion， etc.
