Stub ends are pipe fittings used in place of welded flanges where rotating back up flanges are desired.
Forged stub ends in Yuanyang are manufactured with die stamping and machining techniques. Welding or casting techniques are unacceptable.
Yuanyang's commitment to quality is evident in every step of our process: the steel pipes, strips, bars, and sheets are purchased from trustworthy manufacturers; raw materials are marked with different colors so that they are easily distinguished; and 100% spectral detection is conducted for all of the finished fittings before shipping.
