API 5L PSL2 X70 seamless steel tube for Oxygen, water and oil pipelines used in oil and gas industry.
1. Product Description
API 5L X70 PSL2 seamless steel tube for Oxygen, water and oil pipelines used in oil and gas industry.
API 5L X70 PSL2 is a kind of seamless steel pipe for oil pipeline, which is mainly used to transport oil and natural gas. The tensilstrength of X70 is higher than that of X65,Tensile strength(MPa)≥570,Yield strength(MPa)485～605.Adapt to the higher work environment..At present, our products are exported to many countries, and the quality and service of our products are very satisfactory to our customers. Customers can choose their own products according to their own needs. Please refer to the table below for specific chemical composition and physical performance.
In addition, the product specification level is divided into PSL1 and PSL2, which have different inspection requirements, chemical composition, and different mechanical properties. In total, PSL2 is higher than PSL1, so when ordering according to API5L standard, it is necessary to indicate in the contract that whether the specification level is PSL1 or PSL2 (API5L pipeline pipe).
The surface can be painted and marked, the two ends can be threaded and blunted, the two ends of the steel pipe can be equipped with pipe caps and protective covers, and various export packaging methods can ensure the safe transportation of products
