X52 oil line pipe is specified internationally under ISO 3183, where the same steel is designated L360 - the number refers to the minimum yield strength of 360 MPa. This article ex

EFW stands for electric fusion welding, a process family in which heat from an electric arc fuses the edges of formed steel into a continuous weld seam. Unlike electric resistance

The price of API 5L X52 Line Pipe is affected by a variety of factors, each of which affects the overall production cost and market price.

The rated pressure of API 5L X52 seamless pipe depends on its specifications and wall thickness. ‌

API 5L X52 welded oil pipeline has a relatively simple production process, high production efficiency and a wide range of sizes and specifications. In addition, compared with seaml

1. Mechanical properties X70 steel grade is significantly better than X52 in mechanical properties. The yield strength of X52 is between 360MPa and 530MPa (about 52000 psi), while

API 5L X52 steel pipe is used in the oil and gas industry for its high strength and corrosion resistance in many fields such as drilling, oil and gas transportation and refineries.

Schedule 80 thickness varies depending on the pipe size.

‌The main difference between API 5L and API 5CT lies in their definition, purpose and standard. ‌

What should be done when API 5L X52 large diameter steel pipes are cooled?

The weld inspection methods for API 5L X52 welded line pipe are layered so that each technique covers what the others cannot: surface flaws, volumetric flaws and mechanical perform

API 5L X52 line pipe shall be subjected to hydrostatic test and there shall be no leakage in the weld or pipe body.
