PPR water supply pipe product introduction

product introduction

PP-R water supply pipe series products are produced in accordance with the high standards and strict requirements of ISO9001 quality system. The products fully comply with GBT18742.2, GBTT18742.3 and GBT17219 hygiene standards and relevant health and safety evaluation regulations of the Ministry of Health. PP-R adopts homogeneous welding technology in hot and cold water conveying projects. Its comprehensive technical performance and economic indicators are far superior to other congeneric products, especially its excellent hygiene performance. The whole process from production and use to waste recycling can achieve extremely high hygiene and environmental protection requirements.

products have the advantages of heat resistance, pressure resistance, heat preservation and energy saving, long service life and economy. It will gradually replace other types of existing water pipes and become the leading product. Water contains many different kinds of chemicals, minerals and impurities, contact with the metal pipe wall will produce chemical effects, so that the wall oxidation and fall off and cause secondary pollution, and the raw material of PP-R pipe is the use of recyclable environmentally friendly materials to strengthen polypropylene, it will not release heavy metals or other substances that damage health; pipe wall does not scale, in line with health and health standards, PP-R pipe is the most suitable for drinking water and food industry transportation of sanitary and environmentally friendly water pipes.

Product features

1. Hygienic, no chemical effect, is a green building material. PP-R raw material is a polyolefin, its molecules are only composed of carbon and hydrogen elements, and the health performance is reliable

2. Easy and reliable installation: the use of homogeneous hot melt connection, a joint connection can be completed in a short time, easy and time-saving installation.

3. Thermal insulation and energy saving: thermal conductivity of 0.24W/m · K is only one two hundredth of metal pipe, for hot water pipe heat loss is very small. 4. Light weight, high specific strength: specific gravity is about one-eighth of steel pipe, pressure test strength is high, good toughness, good impact resistance.

5. The inner and outer walls of the product are smooth, the flow resistance is small, and the energy consumption of the conveying fluid system is low.

6. High heat resistance: long-term normal use of conveying water The working temperature is 70 ° C, short-term use of high temperature resistance can reach 95 ° C.

7. Corrosion resistance, no scaling: can avoid pipe fouling blockage and water basin, bathtub macular rust.

8. Long service life: normal service life can reach more than 50 years.

product application range

1. Hot and cold water piping system.

2. Heating systems, including floor and wall heating and radiant heating systems.

3. Pure water piping system.

4. Central (centralized) air conditioning system.

Pipe connection process:

1. After piping, make a socket depth mark at the pipe insertion end

2. Clean the end face of the pipe and pipe fitting. Penetrate the pipe into the pipe joint cover,

3. Heat the pipe and pipe fitting to be connected with a hot melt machine. The heating parameters shall comply with the relevant hot melt machine technical requirements.

4. After the heating time is reached, immediately remove the pipe and pipe fitting at the same time, quickly and uniformly insert it in a straight line without rotation to the marked depth, so that a uniform flange is formed at the joint,

5. Cover the pipe joint cover after welding is completed.

6. The pipe and the pipe fitting are completely fused into one, which is a perfect fit.
