Excuse me, does anyone know what kind of pipe is better for toilet water pipe installation? The PVC drainage pipe of PPR water supply pipe has anti-aging and anti-corrosion effects, and is suitable for the installation and use of toilet water pipes.
What kind of pvc pipe should be used for indoor rainwater pipes? 1. Indoor rainwater pipes generally use UPVC water pipes.
2. The 2.UPVC tube takes PVC resin as the carrier, which has the excellent characteristics of accurate temperature sensing, timely melting and rapid absorption of effective components of additives while reducing the attraction between resin molecular chains. At the same time, the world-famous calcium-zinc composite heat stabilizer is adopted, which can capture, inhibit, absorb and neutralize the release of hydrogen chloride in the high-temperature melting process, and double bond addition reaction occurs with polyene structure to replace the active and unstable chlorine atoms in the molecule. So as to effectively and scientifically control the catalytic degradation and oxidative decomposition of the resin in the molten state.
Third, the characteristics:
1, UPVC pipe is a kind of plastic pipe made of polyvinyl chloride (PVC) resin without plasticizer. With the development of chemical industry technology, non-toxic pipes can be produced now, so it has the properties of general PVC and some excellent properties, specifically, it has the advantages of good corrosion resistance and flexibility.
2. Because it is not conductive, it is not easy to react electrochemically with acid, alkali and salt, and acid, alkali and salt are also difficult to corrode, so there is no need for external anticorrosive coating and lining. Good flexibility overcomes the shortcomings of fragile plastic pipes in the past, and can yield without breaking under load.
3. The weight of 3.UPVC tube is also very light. Advantages of convenient transportation.
What material is used to decorate the closed water pipe in Wuxi bathroom? Common water pipes, such as heating switch and water supply switch, should be closed in a movable way for future use. Unusual downpipes, such as drainage or floor penetration, can be sealed with light steel keel gypsum board, aluminum-plastic board or other integrated board, cement board and ceramic tile, or brick. In any case, the manhole corresponding to the pipeline manhole should be left, and the position of the manhole must be openable. In case of need. You can search for city tour groups, and the information inside is also good ~
Should we choose ppr pipe or pe pipe for home decoration? PE pipes are generally used to transport pressure water and drinking water. The standard of home improvement is often HDPE or MDPE, with two grades: PE80 and PE 100. The sanitary performance of drinking water pipes meets the requirements of GB/T 172 19.

What kind of pipes do you need for the drainage pipes of residential toilets? Whether pvc or ppr 1, the production energy consumption of energy-saving PP-R pipe is only 20% of that of steel pipe, and its thermal conductivity is low [0.2w/(m.k)], which is only 1/200 of that of steel pipe. If it is applied to hot water system, the heat loss will be greatly reduced.
2. Corrosion resistance, no scaling, health and non-toxic. Using PP-R pipe can avoid the "secondary pollution" of water quality caused by scaling and rust on the inner wall of galvanized steel pipe. Due to the simple composition of PP-R, the basic components are carbon and hydrogen, which conforms to the food hygiene regulations and is non-toxic, and is more suitable for drinking water transportation.
3. The long-term service temperature of the heat-resistant, pressure-resistant and long-life PP-R tube can reach 95℃, and the short-term service temperature can reach 120℃. Under the conditions of service temperature of 70℃ and working pressure of 65438±0.2 MPa, the service life can reach more than 50 years after long-term continuous use.
4. Light weight, high strength and low fluid resistance. The density of PP-R pipe is only 1/8 of that of metal pipe, the compressive test strength is as high as 5MPa, and the toughness and impact resistance are good. Because the inner wall is smooth, it does not rust and scale, and the fluid resistance is small. The main technical indexes of PP-R pipe are as follows: density 0.9g/cm3 elastic modulus (20℃)800MPa thermal expansion coefficient 1.8× 10-4/k thermal conductivity 0.2w/(m.k) longitudinal shrinkage 2%, impact test breakage rate ≤ 10% short-term water pressure.
In addition to light weight, corrosion resistance, no scaling and long service life, PP-R pipe also has the following main characteristics:
1, non-toxic and hygienic. The raw material molecules of PP-R are only carbon and hydrogen, and there are no harmful and toxic elements. Sanitary and reliable, it can be used not only for hot and cold water pipelines, but also for pure drinking water systems.
2, heat preservation and energy saving. The thermal conductivity of PP-R pipe is 0.2 1w/mk, which is only 1/200 of that of steel pipe.
3. Good heat resistance. The Vicat softening temperature of PP-R pipe is 13 1.5℃. The highest working temperature can reach 95℃, which meets the requirements of hot water system in building water supply and drainage code.
