Three-layer polyethylene anticorrosive straight seam pipe for winding natural gas transportation
1. Overview. Spiral wound type three-layer polyethylene anticorrosive longitudinal seam pipe for natural gas transmission is an efficient, environmentally friendly and durable pipeline material, which is widely used in the field of natural gas transportation. The pipeline is made of high-strength longitudinal seam steel pipe and high-quality anti-corrosion materials, and is manufactured through advanced production technology. It has the characteristics of excellent corrosion resistance, high strength and low cost, which can ensure the safety, stability and long-term reliability of natural gas transportation.
Second, the production process.
The production process of three-layer polyethylene anticorrosive longitudinal seam pipe mainly includes the following steps:
1.Steel pipe manufacturing: high-quality steel is selected, and longitudinal seam steel pipes are manufactured through cutting, straightening, welding and other processes. The inner and outer surfaces of the steel pipe have undergone strict rust removal and cleaning treatment to ensure that its surface quality meets the requirements.
2.Preparation of anticorrosive materials: high-quality polyethylene materials are selected, necessary antioxidants, ultraviolet absorbers and other additives are added, and anticorrosive layer materials are prepared through mixing, melting, extrusion and other processes.
3.Anti-corrosion layer winding: The prepared anti-corrosion layer material is tightly wound on the surface of the steel pipe using advanced winding technology to form a dense anti-corrosion layer.
4.Testing and packaging: Strict testing of the finished pipeline, including appearance, size, pressure and other tests to ensure that the product meets the requirements of relevant standards. Finally, it is packed for transportation and storage.
Third, performance characteristics.
