Plastic-coated composite pipe, plastic-coated steel pipe, also known as steel-plastic composite pipe, plastic-coated composite steel pipe, is a product that uses PE (modified polyethylene) for hot-dip plastic or EP (epoxy resin) for internal and external coating, with excellent corrosion resistance. At the same time, the coating itself has good electrical insulation and does not produce electrical corrosion.
Low water absorption, high mechanical strength, small friction coefficient, can achieve the purpose of long-term use. Plastic-coated composite pipe can effectively prevent the damage of plant roots and soil environmental stress. The plastic-coated composite pipe is easy to connect and easy to maintain. Epoxy powder spiral steel pipe is pollution-free, epoxy powder anti-corrosion spiral steel pipe refers to the general term of compounds containing 2 or more epoxy groups in the molecular structure and can form a three-dimensional network of solidified substances in the presence of appropriate chemical reagents, which is an important class of thermosetting resins.
The drainage plastic-coated steel pipe adopts a plastic coating process, which forms a strong plastic coating on the surface of the pipe and prevents the occurrence of pipeline corrosion. This plastic coating is resistant to chemicals and maintains the long life of pipes even in humid and corrosive environments, reducing the frequency of pipe repairs and replacements. Compared with traditional metal pipes, drainage plastic-coated steel pipes have obvious advantages in terms of corrosion protection.
Drainage plastic-coated steel pipes also have compressive and impact resistance, and can withstand large external forces without breakage. In the process of use, the drainage plastic-coated steel pipe can withstand large water pressure and earth pressure, and there will be no water leakage and deformation. At the same time, it also has good impact resistance, can withstand mechanical shock and vibration, and is not easy to break. These characteristics enable the drainage plastic-coated steel pipe to maintain good stability and pipeline integrity even in complex environments.
Epoxy resins include both epoxy-based oligomers and epoxy-containing low-molecular-weight compounds. As a resin matrix for adhesives, coatings and composite materials, epoxy resin is widely used in water conservancy, transportation, machinery, electronics, home appliances, automobiles and aerospace fields.
The inner wall of the drainage plastic-coated steel pipe is smooth, which is not easy to produce dirt and scale, and effectively solves the problem of pipeline blockage. In traditional pipelines, due to defects in the inner wall, or improper pipe angles, or foreign objects in the pipes, it is easy to cause the accumulation of dirt and scale, resulting in pipeline blockage. The drainage plastic-coated steel pipe has a smooth surface and has good resistance to dirt deposition and scaling, which can reduce the blockage of the pipeline and keep the drainage system smooth.
