Seamless Line Pipe
Seamless line pipe operating environment of the pipeline, long lines, and not easy to maintain, the quality requirements are very serious.The main material of the tube is gr.b, X42, X46, X56, X65, X70, X80, X100 and other steel grades.
Many of the challenges facing seamless line pipe include：Most oil and gas fields are located in polar, ice sheet, desert and ocean areas, where natural conditions are relatively poor. Perhaps in order to move forward, the diameter of pipeline is expanding, the pressure of pipeline is increasing, and the corrosion of oil products in pipeline activities is also increasing.
From the development trend, pipeline laying conditions, primary failure methods and failure causes of oil and gas pipelines, it is concluded that pipeline steel should have excellent mechanical functions (thick wall, high strength, high resistance to wear and tear), large caliber, weldability, cold and low temperature resistance, corrosion resistance (CO2), seawater resistance, HIC and SSCC functions. And so on.
