The selection of the water supply pipe and the penetration of the contact materials of the pipe in the decoration are likely to cause water pollution, so pay attention to the selection of qualified water supply pipe in the decoration, pay attention to the color of the pipe and the construction process of the pipe reform in the selection.
Water pipes mainly bring three kinds of pollution
According to Song Guangsheng, director of the Indoor Environment Monitoring Committee of the China Association of Decoration Association, people often neglect the selection of water supply pipes in home renovations. Pollution of drinking water pipelines will lead to heavy lead pollution, biological pollution and chemical pollution.
Experts explained that heavy metal lead pollution mainly comes from the heat stabilizer lead salts in PVC plastics; bio-pollution is mainly due to the oxygen penetration and light transmission of the pipe to make the water medium in the tube breed bacteria; chemical pollution mainly comes from the penetration of the pipeline contact materials. .
Choose PPR pipe that meets national standards
The China Indoor Decoration Association Indoor Environment Monitoring Committee pointed out in particular that the drinking water pipes installed and replaced during the renovation must meet the needs of health. All the health indicators of the water pipes must meet the national standards before they can be used, especially the PVC pipes that are prohibited from use by the state and pollute the environment. waterproof material.
When choosing PPR pipe, pay attention to the color of the pipe. Do not choose light PPR pipes such as white. When purchasing plastic pipe for household use, it is best to ask for the product quality inspection report.
After the renovation of a new house or drinking water pipeline, one should be alert to the lacquer and paint odor in drinking water. When unclear diseases and discomforts occur together, the quality of the drinking water should be checked and checked.

Threaded-connection Rubber Joint
Threaded rubber soft joints are also known as threaded UNION rubber soft joints, threaded flexible rubber soft joints, arbitrary rubber soft joints, and threaded soft joints. Flexible Double Ball Wire Button UNION Rubber Soft Joint This product is composed of inner layer, reinforcing layer and outer rubber layer compound model vulcanized rubber double ball and metal flat union. The middle double ball part is added with a steel ring according to user needs, which has high pressure resistance, high and low temperature resistance, strong corrosion resistance, good flexibility, large displacement and deformation, good vibration and noise reduction, flexible installation and long service life.
Main parameters of threaded rubber soft joint
Working pressure: 0.6Mpa, 1.0Mpa, 1.6Mpa, 2.5Mpa
Working temperature: -40 degrees to 80 degrees (also can process high temperature resistant rubber soft joints)
Nominal diameter: DN20-DN80 Material of main parts
Ball body: NR, CR, IIR, NBR, FKM,
Inner and outer lining: NR, CR, IIR, NBR, FKM, EPDM,
Main frame: Nylon cord
Booster ring: multi-strand copper-plated steel wire
Yuren: Cast iron, forged carbon steel (Q235), stainless steel (201, 304, 316, 321)
The main material of the threaded rubber soft joint is neoprene, natural rubber and EPDM rubber, and the threaded rubber soft joint is resistant to natural changes in weather and can be automatically extended. The threaded rubber soft joint is multi-body protection with mesh steel wire. It can prevent the natural shrinkage of the product and reduce aging and cracking during long-term use, and can replace other telescopic products widely used in power plants, water plants, sewage plants, chemical and metallurgical industries. Another important point is that the rubber soft joint is a green product. There is no pollution to humans and no side effects when using this product.
Can be widely used in hotels, factories, residential plumbing piping systems and circulating water pipes, sanitary pipes, chemical anti-corrosion and refrigeration pipes.
The normal applicable medium is ordinary water with a temperature of 0-60 °C. For special media such as oil, acid and alkali, high temperature and other corrosive and hard textures, the corresponding special-resistant material should be selected for soft rubber connection, and cannot be blindly connected. used or generic.
