API 5L X70 Pipe, Grade X70 Line Pipe, X70 Carbon Steel Seamless Line Pipe, X70 PSL1/ PSL2 Carbon Steel Pipe Supplier
X70 Seamless line pipe is a high-strength steel pipe widely used in the field of oil and natural gas transportation. It is usually made of carbon steel. "X" represents the pipeline steel in the API standard, and 70 is the strength grade in kpsi. X70 represents pipeline steel with a minimum yield strength of 70kpsi and has excellent mechanical properties and corrosion resistance. The specification of X70 line pipe is 8-1240×1-200mm.
Pipeline steel refers to a type of steel with special requirements used in pipelines for transporting oil, natural gas, etc. Depending on the thickness and subsequent formation, it can be produced by hot tandem rolling units, steckel mills or plate rolling mills. Large diameter steel pipes are formed by spiral welding or UOE straight seam welding.
Mechanical properties are one of the important indicators for evaluating material performance, and are particularly critical for pipeline transportation. The mechanical properties of X70 seamless line pipe mainly include yield strength, tensile strength, elongation, etc.
Mechanical properties of X70 steel pipe:
Non-proportional extension strength RP0.2 (MPa): 485-605
Tensile strength (MPa): ≥570
Elongation A (%): ≥ 18
4. Excellent welding performance: X70 steel pipes can be connected through a variety of welding methods. The welded joints have high strength and can meet the requirements of pipeline construction.
X70 Chemical analysis:
C: ≤ 0.16
Si: ≤ 0.45
Mn: ≤ 1.70
V: ≤ 0.06
Nb: ≤ 0.05
X70 pipe is a steel pipe material with excellent mechanical properties and is mainly used in oil and natural gas transmission pipelines. Its yield strength is high, and its tensile strength and elongation also meet specification requirements. These excellent mechanical properties enable X70 pipes to withstand large external forces and pressures, ensuring safe and stable operation of pipelines.
