They are the valve housings for pertrochemical equipments. Made from heavy close die forging.
These die forgings are very heavy, the heaviest die forging up to 1,000kg/piece, we had the 10,000 ton friction press to die forge so heavy parts.
These die forged valve housing need to bear high pressure.
Except raw forging, we can also provide the services of heat treatment, CNC machining, assemblying, pressure testing.
