PPR is the abbreviation of type three polypropylene, also called random copolymer polypropylene pipe. It adopts thermal welding method, has special welding and cutting tools, and has high plasticity.
Hose structure is usually divided into: an inner adhesive layer and outer rubber layer and frame layer (or middle-tier), inner adhesive layer directly under transmission medium wear and erosion
PEX pipe, also known as cross-linked polyethylene pipe, is made of polyethylene material. The linear molecular structure of polyethylene is transformed into a three-dimensional network structure through physical and chemical methods, thereby improving the performance of polyethylene.
Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, PPR Pipes has the advantages of energy saving and material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall, easy construction and maintenance, and long service life.
In this century, a revolutionary progress has taken place in the pipeline field, that is, "plastics instead of steel". With the rapid progress of polymer materials science and technology, the deepening of the development and utilization of plastic pipes, and the continuous improvement of production processes, plastic pipes vividly demonstrate their excellent performance. Today, plastic pipes are no longer mistaken as "cheap substitutes" for metal pipes.
