According to stainless fittings manufacturing methods, they are available in types of Elbow, Tee, Cross Tee, Reducer, Cap, Bushing, Plug, Coupling, Union and so on.

According to connection method. They are including butt weld, socket weld and threaded fittings.

Forging Manufacturing Method

Making method of stainless steel forged fittings,using forging machine bevels the stainless steel pipe end or extension, reduce the outside diameter. The common types are rotary, connecting rod and roller type.

Rolling Wheel Manufacturing Method

Stainless steel butt weld fittings, putting the core in the stainless steel pipe. Then pushing the external by roller and processing the rim.

Stamping Manufacturing Method

Using tapered core to expand the stainless steel pipe end to the required size and shape in the punching machine.

Bending Manufacturing Method

For making stainless steel elbow and bend fittings. There are three commonly methods. One is stretching , another is stamping , the third is roller , there are 3-4 rollers. Two fixed rollers and one adjusted roller. Then adjust the fixed rollers spacing and the finished product is bend.

Bulging Manufacturing Method

A rubber is placed in the tube and the top with a punch compression, then the pipe is bulged forming; Another method is hydraulic bulging forming. That is filling the middle of the pipe with liquid, the hydraulic will bulge pipe into the desired shape. This is the most common method for corrugated pipe production.
