PP compression fittings:
The PP compression fitting is a pipe fitting that is mechanically attached. To ensure a perfect hydraulic seal in a pressurized dispensing structure, PP compression fittings require physical forces to form a seal or create alignment. Unlike traditional hot melt for HDPE pipes, PP compression accessories offer a quick, simple and simple new installation method.
PP compression fittings are widely used for water supply and irrigation. PH Plastic Group PP compression joints are manufactured in accordance with EN 712/713/715/911; ISO 3501/3503/3458/3459. The fittings can be mounted on HDPE pipes in accordance with ISO 11922; DIN 8072/8074; UNE 53131. Threaded versions are manufactured in accordance with ISO 7 and DIN 2999.

Application areas of PP Compression Fittings:
  1. The field of water supply pipes in the building. Including hot and cold water for domestic use and hot water for heating.
  2. Drainage pipe field in the building. Mainly PVC construction drainage pipes, as well as a small amount of Pt and PP pipes.
  3. Outdoor water supply pipe field. Including urban and rural water supply pipes.
  4. Buried drainage pipe field. Including urban and rural sewage pipes, rainwater drainage pipes, industrial sewage pipes, etc.
  5. Gas pipe field. Mainly used in urban gas transmission and distribution pipeline network.
  6. Jacketing tube field. Including various sheaths for power and communication cables and optical cables.
  7. Industrial field. Including pipelines that transport liquids and gases during industrial production.
  8. The agricultural sector. Including various pipes for irrigation.

PP is polypropylene, a thermoplastic resin made by polymerization of propylene.
Advantages of PP Compression Fittings:
  1. Non-toxic, non-corrosive, non-scaling, in line with QB1929-93 water supply standard and HG20539-92 standard.
  2. High temperature resistance, the highest water temperature in pipeline can reach 90-100℃.
  3. Light weight, easy to install, transport and connect, which can greatly reduce the difficulty of construction.
  4. Corrosion resistance, which can effectively prevent the corrosion of ions in water or chemical substances on the inside and outside of the pipeline.
  5. The thermal conductivity is very low, so it has good thermal insulation performance. When used in the hot water system, there is no need to add thermal insulation materials.
  6. The resistance of the inner wall of the pipe fitting is very small and will not cause obvious obstruction to the flow of the medium, so the energy consumption is very low when in use
  7. The product has soft colors and various colors, which can meet the needs of various occasions.
  8. The hot-melt connection method can be used to connect the pipes and fittings as a whole, so that the connection of the pipes will be very firm, and it is not easy to leak water at the connection.
