Manufacturing Process Of Super Duplex S32750 Fittings

Forging

Using a forging machine to lower the outside diameter and bevel the pipe end or extension is one method of making forged fittings.

Rolling Wheel

The core is inserted into the pipe using butt weld fittings. After that, processing the rim and pushing the exterior with a roller.

Stamping

Expand the pipe end in the punching machine to the desired size and shape by using a tapered core.

Bending

for creating bend and elbow fits. There are three typical approaches. There are three or four rollers: one is for stretching, one for stamping, and the third is for rolling.

Bulging

A rubber is inserted into the tube and compressed with a punch, causing the pipe to bulge; hydraulic bulging forming is an additional technique.
