The plastic-coated steel pipe is a red modified epoxy resin powder coated inside and outside the pipe. It takes steel pipe as the base pipe, and adopts sandblasting chemical double pretreatment, preheating, internal and external coating, curing, post-treatment and other processes to produce a new type of pipe. The rust and scaling problems of the buried galvanized steel pipe and the water delivery are dealt with, and the signs of suffocation and spraying of the pipeline will not occur, and the service life of the fire water supply pipeline is improved.
In order to beautify the city, create a common path, eliminate the maintenance workload of overhead lines, and improve the robustness of power supply. The method of laying through pipes has been widely accepted over the years. The use of plastic-coated steel pipes for laying cables is simple in construction and convenient for maintenance. Plastic-coated steel pipes used for cable maintenance pipes have many advantages such as good rigid performance, high compressive strength, and good corrosion resistance. The use of weather-resistant or soil environment-specific polyethylene powder with wear-resistant factors as the outer anti-corrosion coating, and the inner coating of strong rubber polyethylene consumes plastic-coated steel pipe cable maintenance pipes. It is a quality upgrade product of traditional cable maintenance pipes.
The plastic-coated steel pipe has good overall performance, and can probably play a very good protective and anti-aging effect on cables and optical cables. It is especially suitable for use under shallow buried roads, bridges and rivers, exposed, and tight corrosion.
