Steel Pipes for Sale: Essential Industry Parameters

Overlay Welding Clad Steel Pipe: Premium Solution Explained

As a world-leading solution among steel pipes for sale, the Overlay Welding Clad Steel Pipe is engineered for ultimate performance in hostile industries. Manufactured by Cangzhou Lion Technology Co., Ltd., this product utilizes breakthrough overlay welding techniques to fuse a wear-resistant alloy layer onto a robust steel tube substrate. The result is a pipe with exceptional resistance to corrosion, erosion, and abrasion, ideal for oil & gas, mining, power, and chemical sectors facing aggressive media.

• Advanced Overlay Process: Hardfacing alloy layer applied with precision, thickness 3-8mm, providing >600 HV0.2 surface hardness.
• Base Steel Options: Carbon steel (Q235B, Q345B), alloy steel (16Mn, 20G), and stainless (304/316L).
• Corrosion & Wear Resistance: Enhanced by chromium, tungsten, molybdenum alloy overlays—10x service life vs standard carbon pipes (Hardfacing Forum).
• Seamless Integration: Overlay welding technology ensures metallurgical bonding, preventing delamination or peeling even in cyclic operations (Materials Science Journal).
• Applications: Slurry lines, high-pressure transport, sour oil pipelines, tailings disposal, and marine outfalls.
• Design Standards: Manufactured in accordance with ASTM, API, GB, DIN for global compliance.
• Low Maintenance: Remote oil & gas installations report up to 70% reduction in annual pipe refurbishment costs (Pipeline-Forum.com).
