Product Overview

Our API 5L Gr.B Seamless Steel Pipe is a premium-grade carbon steel pipe manufactured to the highest international standards, specifically designed for oil and gas transportation pipeline systems. With a robust supply capacity of 10,000 tons per year and full BV, SGS, and ABS certifications, this seamless pipe delivers unmatched reliability in high-pressure, long-distance pipeline applications. Available in sizes from 1/2 inch to 24 inches with wall thicknesses from 2mm to 60mm, our pipes meet the rigorous demands of the global energy sector.

Key Features & Advantages

• API 5L Certified Excellence: Fully compliant with API 5L, ASTM A106, and ASTM A53 standards, ensuring consistent chemical composition and mechanical properties for critical pipeline operations. Tensile strength minimum 415 MPa, yield strength minimum 245 MPa.
• Seamless Manufacturing Process: Produced from a single solid billet through hot-rolling and cold-drawing processes, eliminating weld seams and weak points. This ensures superior structural integrity and high-pressure resistance.
• Multi-Layer Corrosion Protection: Available with FBE, 2PE, 3PE, 2PP, and 3PP coating systems that provide exceptional resistance to moisture, chemicals, and mechanical damage in underground and subsea environments.
• Flexible End Configurations: Supplied with beveled ends for welding, plain ends for mechanical coupling, or threaded ends for quick assembly, meeting diverse pipeline installation requirements.
• Comprehensive Size Range: Outer diameter from 21.3mm to 609.6mm, SCH80 wall thickness, lengths from 1m to 12m fully customizable to project specifications.
