API 5L X60 Steel Pipe L415 LSAW Welded Line Pipe

API 5L X60 (L415) is a line pipe with a minimum yield strength of 60,200 MPa (415 MPa) used in pipeline transportation systems in the oil and gas industry.

X60 can be seamless or welded in several types, the most common of which are LSAW (SAWL), SSAW (SAWH), and ERW.

Due to its high strength and durability, X60 pipe is often used for long-distance cross-regional pipelines or transportation tasks across complex terrain and other harsh environments.

X60 Steel Characteristics
X60 steel is known for its high strength and toughness. It has excellent weldability and corrosion resistance, making it an ideal choice for harsh environments. X60 is mainly used for pipeline transportation of oil, natural gas, and water. It performs well under high pressure and high stress conditions. For applications that require higher strength or higher corrosion resistance, consider using X70 or X80 steel grades. These alternatives have their own advantages in different situations, ensuring that the best material is selected for each project.

Depending on the delivery conditions and PSL level, X60 can be divided into the following categories:

PSL1: X60 or L415;

PSL2: X60N, X60Q, X60M or L415N, L415Q, L415M
