ASME A105 forged fitting 3000psi NPT thread equal tee cross
For the pipe fittings of small size, such as tee, tee and elbow of socket welding and thread, the shape is relatively complex, so the die forging process should be used.
The blank used for die forging shall be a rolled profile, such as bar, thick wall pipe or sheet. When INGOT IS USED AS RAW material, IT SHOULD be rolled into bar IN advance or used as blank for die forging after forging in order to eliminate defects such as segregation and looseness in INgot.
The blank is heated and then put into the die for forging (depending on the situation, it may go through the initial forging and then die forging). The pressure makes the metal flow and fill the die cavity; If the blank after die forging has a flash, it should go through the step of flushing to the flash residual material, so as to complete all the die forging work.
