CNG steel pipes are pipes designed for compressed natural gas (CNG) transportation and storage systems and are widely used in the storage, transportation and related facilities of compressed natural gas. These steel pipes are usually made of high-strength steel, stainless steel or alloy steel, and have good compressive strength, corrosion resistance and high pressure resistance to meet the various requirements required in the storage and transportation of CNG.
The main feature of CNG steel pipes is that they can withstand high-pressure working environments and maintain good strength and durability under high pressure. The wall thickness, strength and toughness of the steel pipes must meet national and industry standards and can effectively bear the huge pressure generated during the compression and storage of natural gas. At the same time, these steel pipes also need to have a certain degree of corrosion resistance, especially in humid or other corrosive environments, which can effectively prevent the external environment from damaging the surface of the steel pipes and ensure the long-term and stable use of the pipelines.
CNG steel pipes also have good processing performance and can be processed by welding, bending and other processes to meet different installation requirements. Its surface treatment process generally adopts pickling, spraying or plating to improve the corrosion resistance and durability of the pipes. During the transportation and storage of compressed natural gas, CNG steel pipes must not only meet strength requirements, but also ensure the sealing and safety of the pipelines to avoid safety risks caused by natural gas leakage.
