1, will the two brands of water pipes have problems when connecting?
Answer: different brands of PP-R tubes have different melting coefficient. It is not recommended to do so. The advertisement board
2. May I ask the workers to install it?
Answer: PP-R water pipe installation process requirements are higher, do not recommend the use of their own workers to install water pipes, one is not the quality of the guarantee, two is to prevent problems from each other wrangling.
3. What is the difference between the cold water pipe and the hot water pipe?
Answer: the thickness of the hot and cold water pipes is different, and the pressure is different. The cold water pipe is 16 kilograms, and the hot water pipe is 20 kilograms. The thermal conductivity of the hot water pipe is 200 points of the metal tube. There is no thermal conductivity in the cold water pipe, and the hot water pipe can pass through the cold water, but the cold water pipe can not pass the hot water.
The PP-R tube has the distinction between cold and heat, mainly from the perspective of economic benefits. After all, the price of the two is different. If the economic conditions permit, all hot water pipes can be used.
4, will the PP-R copper pipe in the quotation refer to the pure copper PP-R pipe? Is it welded?
Answer: PPR copper tube is PPR outside, and there is a 0.5mm thick copper piece inside. It is installed as hot-melt connection.
5, is the copper PPR pipe copper corrosion?
Answer: pure copper PP-R tube is in the outer side of copper tube along the circumferential and longitudinal plastic coating PP-R layer, and through the powerful hot melt adhesive once forming and sticking to the body, this structure forms a small thermal expansion coefficient and easy to melt PP-R composite pipe, which is characterized by heat resistance, pressure resistance, fire resistance and corrosion resistance in one body, never leaking. For more than 50 years.
6. How thick is the copper wall of PP-R copper tube? How much is the difference between PPR copper tube and pure copper tube? If you don't think about the price problem.
Answer: the copper wall thickness of PP-R copper tube is 0.35mm. PPR copper tube copper tube is easier to bend than ordinary pure copper pipe, easy to twist, not easy to crack and break. It still maintains good strength and stiffness at high temperature, and has certain resistance to frost heaving and impact resistance. Its copper pipe and fittings are strong and dense, and the surface forms a thick and solid protective layer, and the water supply is safe and smooth. Advertising board is safe and smooth.
