PP-R pipes pvc pipe are also called three-type polypropylene pipes. They are made of random copolymer polypropylene and extruded into pipes, and injection molded into pipes. It is a new type of plastic pipeline product developed and applied in Europe in the early 1990s. PP-R was in the late 1980s, using a gas phase copolymerization process to make about 5% of PE randomly and uniformly polymerized in the PP molecular chain random copolymerization to become a new generation of pipeline materials. Advantages of PPR pipe: moderate price, stable performance, heat and heat insulation, corrosion resistance, smooth inner wall without scaling, safe and reliable piping system, non-permeable, and a service life of up to 50 years.

PVC pipes are made of hygienic-grade polyvinyl chloride  resin as the main raw material, added with appropriate amounts of stabilizers, lubricants, fillers, coloring agents, etc., extruded by a plastic extruder and injection molded by an injection molding machine, and cooled and solidified , Shaping, inspection, packaging and other processes to complete the production of pipes and fittings. Aluminum-plastic composite pipe is the earliest water supply pipe to replace cast iron pipe. Its basic composition should be five layers, that is, plastic, hot-melt adhesive, aluminum alloy, hot-melt adhesive, and plastic in order from the inside to the outside.


The aluminum-plastic composite pipe has good thermal insulation performance, and the inner and outer walls are not easy to corrode. Because the inner wall is smooth, the resistance to fluid is very small; and because it can be bent at will, it is easy to install and construct. No heavy metal salt stabilizer is added during the processing of PE pipes. The material is non-toxic, has no scaling layer, does not breed bacteria, and solves the secondary pollution of urban drinking water. Except for a few strong oxidants, it is resistant to the erosion of various chemical media; no electrochemical corrosion. The pipeline is light in weight, the welding process is simple, the construction is convenient, and the overall project cost is low.


The domestic thin-walled stainless steel water pipe is a new type of pipe that came out in the late 1990s. Due to its safety, hygiene, high strength, good corrosion resistance, robustness, long life, maintenance-free, and beautiful characteristics, the thin-walled stainless steel pipe with the following Outstanding advantages excellent mechanical properties, superior wear resistance, good safety and hygiene performance, good temperature resistance, good thermal insulation performance, smooth inner wall and low water resistance; beautiful appearance, clean and fashionable, 100% recyclable Use; conducive to saving water resources; wide range of use; service life up to 100 years.
