API 5L Pipe

Our sister company Wuxi beilai Tube Co.,Ltd manufacture API 5L line pipes. Since 1991, Beilai mainly produce seamless pipe tubing and casing and so on.Our products widely used in petroleum, natural gas, chemical industry, construction geological industries. Line pipe mainly used for transportation of gas, water oil. Sour service pipeline is intended for solving the problem of cracking and leakage caused by insufficient resistance to sulfide stress corrosion cracking and hydrogen induced cracking under acidic service environment when developing in acid oil and gas exploration.
