SEAMLESS STEEL PIPE FITTINGS

The seamless carbon steel welding fittings, such as: Elbows, Reducers, Tees and Caps, supplied by us are produced from seamless steel tubing and furnished in accordance with ASTM Standards A234. The dimension, beveled ends  and tolerances are according to ANSI B16.9  "Wrought Steel Butt welding Fittings". The short radius Elbows' dimension, beveled ends and tolerances are according to ANSI B16.28."Wrought Steel Butt welding Short Radius Elbows and Returns". The Pipe Fittings are used for petroleum industry, such as, petroleum and chemical refineries, oil fields, power stations, ship building, etc.

Elbows
The elbows are produced by advanced drawing process of intermediate frequency induction heating. This process is the most up-to-date in the world for elbows forming. After this producing process, the elbows are into next process of reforming for shape, heat treatment, bevel cutting and so on. With a serious quality control system, we have persisted 100% inspection for all products.
The elbows we supplied are from 1/2" to 48" in size and various wall thickness. 
Concentric Reducers, and Eccentric Reducers
Butt Weld Concentric Reducers, and Eccentric Reducers are made from seamless carbon steel pipes, the production is by heating process. The dimension, beveled ends and tolerance are according to ANSI B16.9, materials standards are ASTM A234 WPB and so on.
Tees
Seamless Butt-weld Tees are made by seamless carbon steel pipes which are produced by heating pressure (6 ̄ and above) and cold hydraulic pressure extrusion process (less than 6 ̄), it can keep the shape and size nicety and exact. The cold pressure produce method tees shall be normalized by stress released heat treatment.
