Seamless line pipe transports the oil, steam, and water extracted from the ground to the petroleum and natural gas industrial enterprises through line pipes. Line pipes include seamless pipes and welded steel pipes. The pipe ends have flat ends, threaded ends and socket ends; The connection methods are end welding, coupling connection, socket connection, etc.

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.

Seamless line pipe is used for gas, water and oil transportation in petroleum and gas industries. Seamless steel pipes for shipbuilding oil, boiler tubes, heat exchanger tubes and pipelines in refineries. 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.
