With the successive introduction of new types of pipelines, the pipelines used to transport gas use coated tubes. The internal and external coated tubes are special gas pipelines. The tubes can transport any gas, including: natural gas, gas, methane, gas, etc.. It is a multifunctional pipeline.
Plasticized pipe, this product is a new type of pipe material recently developed in China. It adopts a plasticized protective layer inside and outside, and the middle is a composite structure that enhances welded steel pipes or seamless pressurized steel pipes. It overcomes the defects of rust, corrosion, high pollution, low strength and deformation of plastic pipes, and integrates the common advantages of steel pipes and plastic products. It belongs to the Environmental Protection products promoted by the state. It not only has the advantages of high strength, easy connection, and resistance to water flow, but also overcomes the disadvantages such as water corrosion, pollution, scaling, low strength of plastic pipes, and poor fire performance. The design life can reach 50 years.
