Mechanical Clad Steel Pipes represent a high-performance engineering solution designed specifically for the most demanding environments in the oil and gas industry. In fields characterized by high hydrogen sulfide (H2S) and carbon dioxide (CO2) concentrations, standard carbon steel often fails due to insufficient corrosion resistance, while pure stainless steel becomes cost-prohibitive. Our mechanical clad pipes bridge this gap by fusing a corrosion-resistant inner layer with a high-strength outer backing steel.
Engineered to meet stringent international benchmarks including API 5LD and DNV OS F101, these composite pipes provide a strategic balance of economic viability and technical excellence. By integrating the structural integrity of carbon steel with the chemical resilience of premium alloys, we enable the efficient transportation of corrosive media while significantly reducing overall project CAPEX and long-term OPEX.

The primary advantage is cost-efficiency. Mechanical clad pipes provide the same corrosion resistance as solid alloy pipes by using a thin inner layer of expensive alloy, while the bulk of the pipe is made from high-strength, lower-cost carbon steel.
Our mechanical clad steel pipes are manufactured in strict accordance with API 5LD and DNV OS F101, ensuring they meet the highest global safety and quality requirements for oil and gas transportation.
Yes, they are specifically designed for "sour service" environments. The cladding material is selected based on the specific concentration of H2S and CO2 to ensure complete protection against sulfide stress cracking and sweet corrosion.
The mechanical cladding process utilizes high-precision forming and bonding techniques that create a tight, secure interface, which is then verified through rigorous non-destructive testing (NDT).
Absolutely. The combination of a high-strength carbon steel outer shell and a tough inner alloy ensures that the pipeline can withstand external loads and internal pressure surges without compromising integrity.
They are primarily used in offshore platforms, subsea pipelines, refinery processing units, and high-pressure gas collection systems where aggressive chemicals are present.
