Internal and external plastic-coated pipes, internal and external plastic-coated pipes are melted on the inner wall of the steel pipe with a layer thickness of ~ m polyethylene ( ) resin, ethylene acid copolymer, epoxy powder, non-toxic) or non-toxic polyvinyl chloride and other organic materials, it not only has the high strength, easy connection and water flow resistance of steel pipes It also overcomes the disadvantages of steel pipes being easily corroded, polluted, and scaled when exposed to water, as well as the low strength and poor fire-fighting performance of plastic pipes. The design life can be up to 20 years. The main disadvantage is that bending is not allowed during installation. During thermal processing, electric welding and cutting, the cutting surface should be painted with the non-toxic normal temperature curing glue provided by the manufacturer. The steel pipe is used as the base, and the inner wall is melt-sprayed or adsorbed with food-grade epoxy powder coating or raw materials that are solidified at high temperature through a special process. Technical parameters of internal and external plastic-coated steel pipes: coating material: (modified polyethylene) or (epoxy resin), common colors: black, gray, blue, red, coating thickness: (modified polyethylene)
Definition of plastic-coated steel pipe: Plastic-coated steel pipe is a steel-plastic composite product that uses a steel pipe as the base pipe, plastic powder as the coating material, and a plastic layer or anti-corrosion layer of other materials on its inner and outer surfaces. Classification: Plastic-coated steel pipes are divided into polyethylene-coated steel pipes and epoxy resin-coated steel pipes according to different coating materials. Plastic coating materials: polyethylene powder and epoxy resin powder.
Product technology, plastic-lined steel pipe plastic-lining technology: After pre-treatment of the steel pipe, evenly apply adhesive on the outer wall of the plastic pipe, and then place it inside the steel pipe to expand it to form a steel-plastic composite product. Rotational molding process: The steel pipe is heated after pre-treatment. While the steel pipe is rotating, the polyethylene powder is evenly rolled and spread on the inner wall, and then solidified to form a steel-plastic composite product. , Plastic coating process: Steel pipe is heated after pre-treatment, high-speed plastic coating, and then solidified to form a steel-plastic composite product.
Plastic-lined composite steel pipes are made by lining the inner wall of the steel pipe with thermoplastic pipes such as polyethylene, heat-resistant polyethylene (R) and cross-linked polyethylene according to the requirements of the transmission medium. Therefore, they have the characteristics of both steel pipes and plastics. Advantages of pipes. Internal and external plastic-coated steel pipes use steel pipes as the base material and plastic powder as the coating material. The inner surface is melt-coated with a plastic layer, and the outer surface is melt-coated with a plastic layer or other material anti-corrosion layer. Plastic composite products.
Features of plastic-lined composite steel pipes: hygienic and non-toxic, in line with national food hygiene standards, corrosion-resistant and non-scaling, plastic lining with low thermal conductivity, thermal insulation and energy saving, luxurious appearance, strong decoration, easy installation, connection Safe and reliable, with good heat resistance and anti-aging properties. Characteristics of plastic-coated composite steel pipes: It has the strength of steel pipes and the advantages of plastic pipes such as corrosion resistance, wear resistance, and low fluid resistance. It is a new type of water supply and anti-corrosion pipe. It overcomes the shortcomings of galvanized pipes such as easy rusting, yellow water production, small pipe diameter and blockage due to accumulation, and has a significant effect on preventing secondary pollution and improving water quality.
