1040,45# fixed flange,1040 flange,finish machining flange Forged Steel Flanges
Process procedure:
Forging process flow quality control: Raw material steel ingot into warehouse(test the chemical content) → Cutting→ Heating(Furnace temperture test) → Heat treatment after forging(Furnace temperture test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal diamention, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipmen
Keywords:
Flange connection which are two pipes,pipe fittings or equipment to be fixed on one flange,then connect two flanges with flange gasket,finally use bolts to fasten two flanges,it’s demountable.
