Plastic coating for pipelines and pipework
The plastic coating adheres tightly to the pipe surface, forming a robust protective barrier that effectively prevents contact between the pipe and external corrosive agents, thereby significantly extending the pipe’s service life.
Through thermal insulation, the medium within the pipeline experiences reduced heat loss during transportation. Whether it is hot water, steam, or a refrigerant, the fluid can maintain its set temperature for an extended period, thereby lowering energy consumption and helping enterprises significantly reduce operating costs.
As conduits for transporting critical media such as oil, natural gas, and water, pipelines’ safety and durability are directly linked to the stability of energy supplies and the reliable operation of public infrastructure.
Plastic-lined steel pipe is a steel–plastic composite pipe that uses a steel pipe as the base and features an inner lining of thermoplastic. The base pipe may be seamless steel, straight-seam welded steel, or hot‑dip galvanized steel. Through processes such as diameter‑reduction compounding, thermal expansion compounding, and rotomolding, the plastic liner is tightly bonded to the inner wall of the steel pipe. The outer steel layer provides mechanical pressure resistance and structural strength, while the inner plastic lining isolates the conveyed medium, delivering corrosion resistance and anti‑scaling performance. These pipes are widely used in domestic water supply and drainage, chemical fluid handling, environmental wastewater treatment, and process‑medium transport applications.
