Cangzhou shenlong pipe manufacturing co., LTD. Is a collection development, production, sales and service in the integration of large-scale pipeline equipment manufacturing enterprises, to produce high strength and transmission pipeline pipe fittings (elbow, bend, flange, tee, reducer, reducer), pipe cap, head, socket welding parts, threaded weldments, blind plate, block, eight blind plate), etc.;

Mainly used in: Marine, petroleum, natural gas, such as high pressure pipeline pipe fittings, generally through the gas hydrogen sulfide (H2S) and other toxic gases, the mechanical properties of flange requirements are very high, for ASTM A694 standard steel in China is still in its infancy.
