API 5L clad steel pipe

What is API 5L clad steel pipe ?

API 5L clad steel pipe refers to a type of steel pipe that consists of two different layers of material bonded together.

API 5L clad steel pipe features two layers of different materials bonded together: an inner layer usually made of carbon steel and an outer layer made of a corrosion-resistant alloy.

History

Clad steel pipes date back to the early 1900s, initially used in bridge construction. The welding method was employed, but drawbacks like weld cracking were addressed with the roll bonding process, allowing layers to expand and contract uniformly.

API 5L Standard

API 5L, developed by the American Petroleum Institute (API), sets requirements for manufacturing clad steel pipes for oil and gas pipelines. It covers materials, design, fabrication, inspection, and welding, ensuring performance in various environments.

Performance

API 5L clad steel pipes offer excellent corrosion resistance, making them suitable for high-pressure and high-temperature conditions. The corrosion-resistant layer protects against environmental factors and reduces the risk of leakage.

Applications

Used in oil and gas pipelines, chemical processing, power generation, and water treatment, API 5L clad steel pipes carry oil, gas, water, and chemicals in challenging environments, providing a balance of corrosion resistance and strength.

Conclusion

API 5L clad steel pipes, with their dual-layer construction, excel in providing corrosion resistance while maintaining inner layer strength. Ideal for diverse applications, these pipes ensure durability and reliability in demanding industrial settings.

【H】 Ceramic lined pipe

Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.

【H】 Cast basalt lined steel pipe

Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.

【H】 Ceramic Tile Lined Pipes

Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.

【H】 Rare earth alloy wear-resistant pipe

The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.

【H】 Tubes Erosion Shields

Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.

【H】 ASTM A213 T91 Alloy Tube

The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
