Product Overview
Lishui PP-R hot and cold water pipes are 100% made of imported pure raw materials specially designed for polypropylene pipes, and introduced domestic and foreign advanced production equipment.
and technical processes, produced in strict accordance with GB/T 18742-2002 standards.
Product features
① It is hygienic and non-toxic. It is a stunning environmentally friendly building material. It is non-corrosive, never scales and does not breed bacteria. It is non-toxic and harmless and fully complies with the national drinking water hygiene standards.
②Thermal insulation and energy saving, the inner and outer walls are smooth and the resistance to water flow is small, and the heat loss when used in hot water pipes is very small.
③High temperature resistance, long-term normal use temperature can be 70℃, short-term use can withstand high temperature of 95℃
④Has good environmental adaptability and chemical corrosion resistance.
⑤The normal service life of pipelines is not less than 60 years.
Application fields
It is used in hot and cold water pipe systems, heating systems and central air-conditioning systems in buildings, pure water supply systems for direct drinking, and food industry pipe systems.
PP-R net safety pipe
There is also a kind of PPR pipe called net safety pipe, the color is: green.
Product Overview
Lishui PP-R net safety pipe is made of 100% imported pure raw materials and is made of multi-layer co-extrusion through special processes and equipment. The pipe has a two-layer structure. An antibacterial agent with silver ions as the active ingredient is added to the inner pipe wall. This material has a bactericidal effect by destroying the respiratory system and cell wall functions of microorganisms. At the same time, its molecular structure has a neutron structure. Contains hydroxyl groups. Due to the negative electrostatic effect of halogen atoms, the acidity of the hydroxyl groups is significantly increased, which strengthens the bactericidal ability and has a broad-spectrum bactericidal effect, thereby improving the quality of water passing through the pipe. It is a truly green and environmentally friendly product.
Product features
① The inner and outer walls are smooth and the resistance to water flow is small. It is ideal for thermal insulation and energy saving and is suitable for hot water pipes with minimal heat loss;
② High temperature resistance, long-term normal use temperature can be 70℃, short-term use can withstand high temperature 95℃;
③Long service life, good environmental adaptability, good chemical corrosion resistance, and the normal service life of the pipeline is not less than 60 years;
④ Hygienic and non-toxic, it will not cause changes in taste and taste when used as a water supply pipe to transport drinking water;
⑤ It has antibacterial effect, and the antibacterial rate against Escherichia coli and Staphylococcus aureus is over 99%.
Application fields
It is used in hot and cold water pipeline systems in buildings, heating systems and central air-conditioning systems, pure water supply systems for direct drinking and food industry pipeline systems, etc.
PP-R pipe fittings
Product Overview
Lishui PP-R pipe fittings have a generous appearance design and use unique circumferential reinforcing ribs, which not only enhances the strength of the socket during welding, but also increases hand-held stability during welding operations. The pressure level of the pipe fitting design is S2.5, which ensures the pressure resistance of the product. The pipe fittings with inserts use dovetail grooves and a stopper groove structure on the inserts, which effectively improves air tightness and safety.
Product features
① The insert is forged and formed from high-quality brass, and the blank is subjected to high-temperature heat treatment in a high-frequency tempering furnace to remove the forging stress, enhance the plasticity of the material, and improve the mechanical properties of the insert.
② The surface of the external thread insert adopts straight tooth technology, which can prevent the raw material belt from slipping and ensure a safe and water-tight connection.
Application fields
It is used in hot and cold water pipeline systems in buildings, heating systems and central air-conditioning systems, thermal energy circulation systems, direct drinking pure water supply systems and food industry pipeline systems, etc.
