　　I. Steel Pipes

　　Steel pipe is one of the most widely used materials in natural gas pipelines. Its advantages include high strength, excellent corrosion resistance, and a long service life, while it also delivers outstanding performance under demanding conditions such as high pressure and large flow rates. When selecting steel pipe, it is essential to consider the chemical environment, temperature, pressure, and other relevant factors to ensure the pipe’s integrity and stability.

　　II. Plastic Pipes

　　As a new type of piping material, plastic pipes offer advantages such as light weight, ease of installation, simple maintenance, and excellent corrosion resistance. They also provide superior sound insulation and thermal insulation, delivering outstanding performance in certain specialized environments. When selecting plastic pipes for specific applications, it is essential to choose the appropriate material to prevent issues like deformation and premature aging.

　　III. Composite Pipes

　　Composite pipes are engineered by integrating advanced materials and cutting-edge technologies into conventional pipe materials, offering advantages such as lightweight construction, corrosion resistance, heat resistance, and high-pressure tolerance. Depending on the specific application requirements, composite pipes can be configured with various material combinations to achieve superior performance and stability. They are widely used in the transportation of liquefied natural gas and other fluids under critical conditions, playing an indispensable role in these applications.
