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. The price is also very economical. With an external insulation layer, the insulation performance is better, and the pipe wall is also very smooth, excluding the joints of the inner and outer wires. It is generally used in embedded walls or deep well embedded pipes. PPR pipes are moderately priced, stable in performance, heat-resistant, heat-insulating, corrosion-resistant, smooth and non-scaling, the piping system is safe and reliable, impermeable, and has a service life of up to 50 years. However, the construction technology requirements are high, and special tools and professionals are required for construction to ensure the safety of the system.
Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, PPR pipes have the advantages of energy saving, material saving, environmental protection, light weight, high strength, corrosion resistance, smooth inner walls, simple construction and maintenance, and long service life. It is widely used in construction, municipal, industrial and agricultural fields such as building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheath, industrial fluid transportation, agricultural irrigation, etc.
