Premium Line Pipe Steel for High-Pressure Pipeline Projects

Product Overview

API 5L X65 and X70 steel plates are high-grade pipeline steels used extensively in long-distance, high-pressure oil and gas transmission pipelines, particularly in offshore and extreme environments. With higher yield strength, these grades are often chosen for critical pipeline infrastructure projects requiring greater durability and reduced wall thickness.

CJM provides API 5L PSL1 and PSL2 X65/X70 plates, meeting both mechanical strength and toughness requirements.

Product Advantages

• ✅ Superior strength-to-weight ratio
• ✅ Excellent resistance to sour service conditions (PSL2)
• ✅ Enhanced weldability and fracture toughness
• ✅ Available in heavy gauge sizes and wide widths
• ✅ Ideal for deepwater pipelines, high-altitude, and arctic conditions

Typical Applications

• Crude oil and natural gas pipelines
• Subsea and offshore transmission systems
• Cross-country high-pressure pipelines
• Structural and riser applications in oil & gas projects
