1, PPR pipe, PPR brass, PPR aluminum pipe What are the differences between the three? What kind of family are used?
PP-R pipe, also known as three polypropylene pipe, raw material molecules only carbon, hydrogen elements, there is no harmful toxic elements exist, hygienic and reliable, not only for hot and cold water pipes, but also for pure drinking water system. PPR brass inner surface is covered with copper PPR. PPR coated aluminum tube covered with a layer of PPR.
2, how much water pipe life?
Conventional water temperature about 60 degrees, the service life of up to 50 years.
3, PPR What is the name of water pipes?
PPR pipe formally known as random copolymer polypropylene pipe, is currently used in home improvement projects in a water supply pipe.
4, PPR pipe is divided into cold water pipe and hot water pipe how to distinguish?
PPR pipe is divided into cold water pipe and hot water pipe, the difference is that the cold water pipe has a blue marking line, hot water pipe is the red line.
5, why PPR pipe color is not the same?
This is due to the difference in raw PPR particles. Therefore, Pierce water pipes are white, while the butterflies are gray, does not mean that the product quality level.
6, PPR pipe in addition to water pipes, the components are there?
Commonly used PPR pipe fittings have four kinds, generally welded on the water pipe: 1 beam section: When the pipe is not long enough, the connection of two pipes used. 2. Elbow: Right-angle bend and 45 bend, when the water needed to use the corner. 3 links: connect the three directions of the water pipe.
4. Size of the head: the connection of two pipes of different diameter pipe connections, the above-mentioned beam joints, elbows, tees have the corresponding size head, rarely used in the home improvement.
5. In the wire, the wire: connecting faucets, water meters, other types of plumbing, home improvement is used in most of the wire pieces. The inner wire and the outer wire joint are more expensive, and the price of one wire connector is even more expensive than the one meter pipe. 6. As of the valve / ball valve: opening and closing flow
6. Around the bend: two pipes intersect in the same plane without the use of docking. • Plug: also known as bulk head, water pipes installed temporarily closed for the outlet, remove the faucet.
7, PPR pipe connection technology What are the characteristics?
PPR pipe interface using hot melt technology, fully integrated between the pipe together, so once the installation of pressure test passed, never again leakage, high reliability.
8, PPR water quality how to judge?
1. First look at the appearance of high-quality pipe smooth appearance, complete logo, accessories also have brand name; inferior products can not do that. Because of the quality of the pipe using 100% imported PPR raw materials, low-quality pipe using only part of the PPR raw materials, both in terms of performance are very different. 2. Toughness: good quality PPR tube toughness, can easily bend into a circle without breaking, and the poor quality of the tube is more brittle, a bend that is broken. 3 thermal expansion and contraction: good water pipe can still maintain the hardness at high water temperature, while the poor quality of the tube is softened at 60 degrees water temperature. 4. Life: quality product warranty 50 years, inferior products only 5-6 years.
9, how to prevent water pipe explosion?
PPR pipe different with the iron pipe, workers should be gently installed when installed, throwing free throwing accessories were not found any small cracks, so completely closed the above situation will occur.
