Fire-fighting plastic-coated steel pipe has good chemical stability and water resistance. It has the functions of drag reduction, anticorrosion, compression resistance and anti-bacterial. It is generally not subject to the constraints of transport media, plastic coating and steel has a strong bonding force. Coating Material: Epoxy resin (EP) is suitable for working environment below 80 C. The steel pipe coating has high adhesion, high hardness, good impact resistance and good chemical corrosion resistance.
Plastic-coated composite steel pipes, we usually refer to double-sided plastic coating, also known as internal and external plastic coating pipes, for Plastic-Coated composite steel pipes, the pre-rust removal process plays a vital role in the quality of finished pipes. Therefore, it is not necessary to galvanize the new steel pipe, but a small amount of rust spots in the pipe need to be removed if the rust is to be removed. The minimum requirement is St2 or Sa1 for electric rust removal. To remove the oil stain on the surface of steel pipe, we can use it to clean the surface.
As the inner and outer plastic-coated steel pipe is more safe, the high-efficiency insulation of polyethylene makes the use of wire safer, and the plastic-coated steel pipe can isolate the wire and the environment, so the wire will not be affected in use, and the power supply environment in the residential area will be safer under the protection of the plastic-coated steel pipe.
Fire-fighting plastic-coated steel pipe manufacturer's excellent mechanical properties of steel pipe continue the advantages of steel pipe, its high mechanical strength, impact, bending and other external effects have a strong bearing capacity, can withstand harsh use conditions, high safety.
The plastic coating has strong acid and alkali resistance, soil corrosion resistance and weather resistance. It is suitable for conveying fluids containing sulphur, calcium, magnesium and other corrosive media in underground coal mines. Modified food-grade epoxy resin powder (EP) coatings or coatings formed by poly powder (PE) are odorless and can reach direct drinking water.
