The tolerance of butt welding pipe fittings

Hebei Haihao Group have more than 30 years production experience about the butt welding pipe fittings products(What’s butt welding pipe fittings?),our butt welding pipe fitting products including:

pipe elbows (45/90/180 degree elbow,long radius elbow,short radius elbow),
pipe tees (equal tee,reducing tee,lateral tee,barred tee,split tee),
hot induction bends (1.5D,2D,3D,5D,7D bend),
pipe reducers (concentric reducer,eccentric reducer),
pipe caps,paddles,stub ends,pipe crosses etc.

Our butt welding pipe fittings products commonly according to standard ANSI/ASME B16.9 and ANSI/ASME B16.28,there are other standards about butt welding pipe fittings such as:EN 10253,DIN,JIS,MSS SP-43,MSS SP-75,GOST.We also manufacture the butt welding pipe fittings as per client’s requirements. 

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:
