The PP-R pipe conforms to European standards for drinking water transport (Brass pipe, nickel-chromium-free).
- Better corrosion resistance: Copper pipe fittings are made of lead-free environmentally friendly copper, which has better corrosion resistance compared to common brass.
- Colorless and odorless: The PP-R pipe does not produce irritating odors when hot melted.
- Good corrosion resistance: The PP-R pipe does not have any chemical effect on all ions in water and chemicals in buildings.
- The PP-R pipe has excellent temperature resistance and pressure resistance
- The PP-R pipe has low flow resistance and no fouling
- PP-R raw materials supplier: Borealis

The excellent thermal stability and purity of PP-R materials are two of the biggest advantages of these systems. The PP-R material's physical and chemical properties are suitable for potable water and heating systems. More importantly, the material's good welding and melting properties allow for permanent integral connection.
- Mark the insertion of the pipe. (Equal to the insertion depth of the joint).
- The surface of pipes and joints should be stable, clean and oil-free.
- Heat the entire insertion depth, including pipes and joints in the welding tool.
- Connect the pipe and joint.
- When the heating time is completed, smoothly and evenly push the pipe into the joint to form a firm and perfect combination.
