FORGED PLUG
1. Description
In the seamless steel pipe production, the plug will wear a solid billet into a hollow capillary, the metal variant is mainly operated on the plug, so the plug quality will directly affect the pipe quality and the plug's consumption.
The common cast plug has loose structure, poor compactness and easy to cause pores and shrinkage, so the average life unable to meet production requirement.
The production process of forged plug is as follows: forging stock - cutting - drawing - heating - forging - machining - heat treatment – inspection - packing and shipment.
