Product Description


    Line pipe GB/T9711-2011 L245N,L290N,L360N,L415N,L450N,L485N,L555N; API 5L PSL1/PSL2 X42,X46,X52,X56,X60,X65,X70,X80,X100Q for oil, gas, water and slurry services;
    Line pipe is used for oil and gas transportation, it can be applied to oil and gas, chemical and electric engineering industry.Since the percentage of sulphureous well increase both in domestic and international oil production, a large number of sulfide exists in the environment of petroleum transportation, which requires higher sour service standards. Sour service line pipe is the optimal production for this situation stated above. Product sour service line pipe covers all the grade of API 5L to meet different requirement of customers, and provide satisfied service to our customers.
BNS/X42NS/X46NS/X52NS,BQS/42QS/46QS/52QS/56QS/X60S/65QS/70QS/80QS,Standard GB/T9711-2011,Petroleum and natural gas industries - Steel pipe for pipeline transportation systems API SPEC 5L Specification for Line Pipe , The rolling procedure is precisely controlled for perfect dimension. After the heat treatment, the performance of our product can satisfy the standard requirement of API 5L. We also have our own HIC and SSC lab to test product performance and guarantee the anti-corrosion of our product.Service environment Sour service line pipe is designed for the acidic oil and gas exploration environment to solve the leaking and cracking problem due to HIC and SSC. Generally, service environment temperature is closed to ground surface temperature, partial pressure of CO2≤0.2MPa, H2S≤0.0003MPa.
