The service life of seamless steel tubes depends on the environment in which they are used. For example, in a harsh environment, ordinary seamless steel tubes will be corroded and rusted within 3 to 5 months. Effective anti-corrosion measures will not only prolong the service life of steel tubes, but also have products. The inner wall is smooth, and the circulation diameter is not reduced, and the conveying efficiency is improved. At present, the commonly used anti-corrosion measures for conveying fluid seamless pipes in China are galvanized, plastic coated and lined plastic. The galvanized seamless steel pipe is coated with a layer of zinc inside and outside the seamless pipe, which can be easily used for anti-corrosion and has a long service life.

Compared with galvanizing, the plastic coated conveying fluid seamless pipe has long-lasting rust-free, non-scaling, non-biological, fast flow rate and large flow rate, ensuring safe and good use in fire protection, while lengthening maintenance cycle and reducing maintenance. The cost and the cost of replacing the pipe are eliminated. In addition, powder coatings for plastic coated steel pipes do not pose a health hazard to paint producers and painters. And the powder coating is applied in a closed system, and the coating utilization rate is as high as 98% or more.

Internal and external plastic coated steel pipe, inner and outer plastic coated steel pipe is melted in the inner wall of steel pipe with a thickness of 0.5 ~ 1.0mm polyethylene (PE) resin, ethylene-acrylic acid copolymer (EAA), epoxy (EP) powder, non-toxic poly Steel-plastic composite pipe made of organic materials such as propylene (PP) or non-toxic polyvinyl chloride (PVC). It not only has the advantages of high strength, easy connection and water flow impact resistance of steel pipes, but also overcomes the corrosion of steel pipes. The design life expectancy is up to 50 years due to the disadvantages of pollution, scale and plastic tube strength, poor fire performance.

The lined plastic conveying fluid seamless pipe is a new quality product, which is especially quick and easy to install. It has the characteristics of effectively preventing secondary pollution of water quality, and is a new generation of products that replace galvanized steel pipes, thus having an environmental protection concept. Lined with plastic (PE), heat-resistant polyethylene (PE-RT), cross-linked polyethylene (PE-X), polypropylene (PP-R), hard polyvinyl chloride (PVC-U) according to the requirements of the transport medium Made of thermoplastic pipe such as chlorinated polyvinyl chloride (PVC-C).

Due to process improvements, some products have increased the outer plastic layer. Through calculation and comparison analysis, the use of plastic-lined steel pipe installation saves labor costs by 35% compared with steel pipe installation, and the effect is very good. Users generally reflect that the pipeline is sanitary, beautiful, easy to install, interface is tight, strong and durable, and it is an environmentally friendly benefit for the public. product. The water-lined plastic malleable cast iron pipe fittings are formed by injection molding of the malleable cast iron pipe by heat and pressure injection.
