CLAD PIPE

• 

In recent years, with the large-scale exploitation of offshore oil and gas, submarine and land pipelines laying laid into the high speed construction. The special marine environment requires more anti-corrosion and relatively economic pipes. The bi-metal pipe contains the carbon steel excellent performance, economy, and the lining (corrosion resistance alloy) corrosion resistance. Meanwhile, with 3 LPP anti-corrosion technology, the bi-metal pipe make the overall mechanical properties of the pipe and internal and external corrosion resistance combine perfect . Its life span can be extended, and it can be served at certain high temperatures.

Manufacturing Process of Clad Pipe

The manufacturing process of the bi-metal composite pipe is to insert the processed thin stainless steel or nickel alloy layer into the the carbon steel pipe, and make the lining stainless steel pipe mechanically fit to the inner wall of carbon steel by the mechanical pressure or explosion shock wave. The welding of bi-metal clad pipe is much stricter than an ordinary carbon steel pipe, especially the harsh conditions such as high humidity, high salt content and dark surge, which put forward higher requirements for the slope and edge processing of the metal clad pipe port. Pipe end protection is the most important, and the service life of the anti-corrosion layer depends on the surface treatment. Generally, the clad pipe is mechanical clad process (explosive bonding) and metallurgical clad process (hot rolling). The bi-metal clad pipe has also been widely used in oil and natural gas.

In modern life, natural gas has replaced coal gas as the leading role in the kitchen. Natural gas is economical, environmentally friendly, safe and reliable. How does natural gas come from? It is transported from oil fields to refineries through pipelines and can be used directly after processing also requires pipelines. What's the black thing outside the pipe? It is to do anti-corrosion, natural gas pipelines due to the buried transmission are easy to be soil environment erosion, so doing an anti-corrosion layer is necessary. Will the inner wall of the pipe be corroded?

Do you want to do a preservative? Sure. The inner wall of natural gas should be corroded. There is hydrogen sulfide, carbon dioxide and other acid gases in the natural gas, which cause corrosion threat to pipeline and affect the safe operation of natural gas pipeline. Therefore, the inner wall of natural gas pipeline must be protected against corrosion in the operation.

But what kind of corrosion is used on the inner wall? The best anti-corrosion effect of the inner surface of natural gas transmission pipeline is stainless steel corrosion. It is a thinner stainless steel layer inside, and the other metal material outside. They are tightly combined to be another new metal clad material by a special production process.

It is called a clad pipe. At present, oil and gas gathering pipeline with anti-corrosion is the best in the field of oil and gas.
