API 5L X65 / X70 Pipeline Steel Plate – Up to X80 Grade Available

Product Overview

CJM Steel supplies API 5L X65, X70, and X80 pipeline steel plates manufactured to meet international pipeline construction requirements for oil and gas transmission projects. API 5L X65 / X70 / X80 pipeline steel plates are widely used in oil and gas transmission pipelines, high-pressure transport lines, and long-distance pipeline infrastructure projects.

Compared to lower grades such as X42–X52, API 5L X65, X70, and X80 pipeline steel plates offer higher yield strength, reliable weldability, and improved resistance to corrosion and cracking under demanding pipeline service conditions.

API 5L X65 / X70 / X80 Pipeline Steel Plate Product Specifications

The following specifications apply to API 5L X65, X70, and X80 pipeline steel plates, manufactured in accordance with PSL1 or PSL2 requirements:

• Thickness: 6–100 mm
• Width: up to 3600 mm
• Length: as required
• Certification: EN 10204 3.1 / 3.2
