Stainless Steel Buttweld Fittings are commonly used to join pipes to valves, fittings or other parts by ways of butt-welding. They are made from stainless steel pipes or plates through the procedure of cut, heat, forming, machining, sand blasting etc.

The above is only an example, dimensions info for other fittings to be provided upon request.
Butt welding is strong and provides well leakage proof.
It makes the piping system a continuous steel structure at the joint parts of pipes and fittings.
