line pipe steel
Modern line pipe steel belongs to low carbon or lowest carbon micro alloyed steel, which is a high technology and high value-added products. Line pipe steel production nearly applies 20 years of all new technology achievement of metallurgy field. The development trend of pipeline engineering is large tube, high pressure gas transportation, high cold and corrosion service environment and the thick wall of seabed pipeline. Therefore, modern pipeline steel should have high strength, low lattice effect, high toughness and brittle fracture resistance as well as low welding carbon, good weldability and HTC and H2S corrosion resistance.
Line pipe steel is mainly used to manufacture oil and gas pipeline. Oil and gas pipeline is the most convenient and the securest channel to connect resource area and market area. The rapid construction of line pipe steel will not only ease the pressure of railway transportation in our country, but also to ensure the safety of oil and gas market supply, is advantageous to the progress of our country's energy security level and ability.
