Pipe characteristics and benefits:
Great resistance to abnormal stress
Due to its high ring stiffness and proper axial flexibility, in case that soil sinking, groundwater floating, earthquake or excessive local load occurs, the welding neck flanges is able to relieve the excessive stress caused thereby through elastic deformation and consequently avoid leakage or damage at the joint or failure of the pipe.
Our welding neck flanges manufacturing process strictly accord to the GB, JIS, DIN, ASME etc. Applying advanced testing, forgeing technique, so guarantee steel flanges' quality reliable and steady. Durable high strength, high oxidation resistance, corrosion resistance and have good organizational stability.
