Butt Welding Pipe Fitting Tolerance

In Hebei Haihao,we have more than 30 years production experience about the butt welding pipe fittings products,which including the steel elbows(45°,90°,180°,long radius,short radius elbow),steel tees(equal,reducing,straight,lateral,barred pipe tee),pipe reducers(concentric,eccentric reducer),pipe cap,stub end.

The butt welding pipe fittings according to standard ANSI/ASME B16.9 and ANSI/ASME B16.28,our butt welding pipe fittings are commonly made from two kinds of raw material:steel pipes and steel plate.To fulfill each requirement of customers and to meet with international specifications and dimensional standards, we follow stringent quality control.The butt welding pipe fitting tolerance within the scope of the following:

Butt Welding Pipe Fitting General:

Cross-sectional tolerances for all butt welding pipe fittings (ASME/ANSI B16.9 and B16.28)

Alignment tolerances are concerned with the way that the ends of a fitting are cut. Exaggerated distortions are shown for clarity in the diagram below.
