PP-R pipe adopts hot melt connection, and the following points should be paid attention

• ① When the hot-melt tool reaches the working temperature, the indicator light can start working;
  ② When cutting the pipe, the end face shall be perpendicular to the pipe axis. Special scissors or pipe cutting machine are usually used for pipe cutting, and sharp hacksaw is used when necessary, but the pipe section must be removed after cutting;
  ③ PP pipes and fittings shall be clean, dry and oil-free; For weld elbow or tee, pay attention to its direction according to the requirements of design drawings
  

Characteristics of PP-R pipe

• 1. No corrosion: polypropylene pipe can withstand acid-base corrosion in a large temperature range and 1 ~ 14 high concentration.
  2. Wear resistant and scale free: the inner wall of PP pipe fittings is uniform and smooth, with small flow resistance and no scale.
  3. Reduce vibration and noise: PP pipe has excellent sound insulation performance, which can significantly reduce the vibration and noise caused by liquid flow.
  4. Anti freezing cracking: PP material has good elasticity, so that the cross section of pipes and pipe fittings can expand with the frozen expansion liquid without expansion and cracking.
  5. Anti condensation and reduce heat loss: PP material is a poor heat conductor, which can reduce condensation and heat loss.
  6. Simple installation: PP pipe has light weight, convenient installation and operation and good weldability.
  7. Long service life: under the specified service conditions, the service life of PP pipeline system can reach 50 years.
