1.Non-toxic and sanitary: The raw material molecules of PP-R are only carbon and hydrogen. There are no harmful and toxic elements. It is sanitary and reliable. It is not only used in hot and cold-water pipes, but also used in pure drinking water systems.
2. Thermal insulation and energy saving: The thermal conductivity of PP-R pipe is 0.21w / mk, which is only 1/200 of that of steel pipe.
3. Good heat resistance: The high working temperature can reach 95 ℃, which can meet the requirements of hot water system in building water supply and drainage specifications. PPR pipe machine manufacturers varies, it’s vital to choose a reliable one.
4. Long service life: PP-R pipe at a working temperature of 70 ℃, working pressure (P.N) 1.OMPa conditions, the service life can reach more than 50 years; at room temperature (20 ℃) service life can reach more than 100 years.
5. Easy installation and strong connection: PP-R has good welding performance. Pipes and fittings can be connected by hot-melt and electric fusion. It is easy to install and the joint is strong. The strength of the connection part is greater than that of the pipe itself.
1.Light weight, convenient transportation and loading and unloading: PVC pipe is very light in material, convenient for transportation and construction, which can be produced by PVC pipe extrusion line.
2. Excellent chemical resistance: PVC pipe has friendly acid, alkali and corrosion resistance, which is very suitable for the chemical industry.
3. Small fluid resistance: The wall of PVC pipe is smooth, and the resistance to fluid is small. Its roughness coefficient is only 0.009, which is lower than other pipes. At the same flow rate, the pipe diameter can be reduced.
4. High mechanical strength: The water pressure resistance, external pressure resistance, and impact resistance of PVC pipes are very good, which is suitable for piping projects under various conditions.
5. Good electrical insulation: PVC pipe has excellent electrical insulation, which is suitable for the conduit of electric wires and cables, and the piping of electric wires on buildings.
1.The two materials are different: PVC is made of polyvinyl chloride, and PPR pipe is made of random copolymer polypropylene.
2.Color difference: PPR pipe toughness is better than PVC, and good quality and bright color, others have a light milky yellow, and poor quality color and disorder. The PVC pipe is milky white, the material is harder than PPR, and there is no light in the cross section, but the outer surface is shiny.
3. Difference in wall thickness: The diameters of PPR and PVC pipes are the same. The biggest difference is in the wall thickness, PPR pipe thickness, and PVC pipe wall thickness. There are words on PPR pipe and PVC pipe, it will be clear at a glance, and the toughness of PPR pipe is good. Under the same pipe diameter, the wall of PPR pipe is usually thick.
