Gaoling

plastic coated composite pipe is a steel plastic composite pipe composed of a layer of polyethylene (PE) resin, polyurea, ethylene copolymer (EAA), epoxy (EP) powder, non-toxic (PP) or non-toxic polyvinyl chloride (PVC) and other organic substances with a thickness of 0.5 ~ 1.0mm on the inner wall of the steel pipe. It not only has the advantages of high strength, easy connection, water impact resistance of the steel pipe, but also overcomes the problems of corrosion, pollution Scaling and low strength of plastic pipes, poor fire performance and other shortcomings. The main disadvantage is that bending is not allowed during installation. During thermal processing, electric welding and cutting, the cutting surface shall be painted with non-toxic normal temperature curing adhesive equipped by the manufacturer. According to the introduction of coating for threading, plastic steel pipe is a steel plastic composite pipe made with welded steel pipe as the base material and adopting sand blasting chemical dual pretreatment, preheating, internal and external coating, curing, post-treatment and other processes. It has excellent comprehensive performance, strong corrosion resistance and mechanical property, good chemical stability and water resistance, and has the functions of drag reduction, corrosion prevention, compression resistance, antibacterial, etc. It is generally not restricted by the transmission medium, and the plastic coating has a strong binding force with steel. Coating material: epoxy resin (EP) is applicable to the working environment below 80 ℃. The steel pipe coating has high adhesion, high hardness, good impact resistance and good chemical corrosion resistance. Its performance is basically determined by the performance of the main plastic. Plastics can be divided into thermoplastics and thermosetting plastics according to their performance changes after heating. The cable protection tube has excellent comprehensive performance, which can play a good role in cable protection and anti-aging, while reducing power loss.
