Plastic-coated steel pipe not only has the advantages of high strength, easy connection, and water flow impact resistance of steel pipe, but also overcomes the disadvantages of easy corrosion, pollution, and scaling of steel pipe in water and low strength and poor fire protection performance of plas

With the continuous development of my country's economy, the country has vigorously developed the energy industry. Long-distance API oil and gas pipelines are an important way to ensure energy security. In the process of anti-corrosion construction of oil (gas) pipelines, the surface treatment of hi

1. Petrochemicals: crude oil, refined oil, petrochemical raw material finished product pipelines, and oil field pipelines.2. Natural gas: submarine and onshore long-distance pipelines; gas receiving station gas pipelines; gas fields and urban natural gas pipelines.3. Coal: transportation of coal, wa

In addition to being used for oil extraction, oil casing can also be used as a pipeline for transporting raw materials. To enhance the quality of oil casing, every link in the production process is particularly important, especially the temperature control during the period, which must be strictly c
