PPR pipe selection
1. Appearance quality tube adopts 100% imported PPR raw material, smooth appearance, complete identification, and anti-counterfeit identification on accessories
2, good toughness PPR tube toughness, can easily be bent into a circle without breaking, inferior tube is more brittle, a bend that is broken
3, thermal expansion and shrinkage of the water pipe can maintain the hardness of the water temperature of 90 degrees, the inferior pipe is softened at 60 degrees water temperature
4, service life quality product warranty for 50 years, poor quality products only 5 to 6 years
The most common problem with PPR plumbing is leaking water. In addition to purchasing quality plumbing, installation specifications are also important:
1. When using PPR fittings with metal threads, seal tape must be used to avoid water leakage at the threads
2, the pipe should not be tightened too tightly to avoid cracking
3, the end of the pipe 4 ~ 5 cm best cut off
4, winter construction should avoid crushing, knocking, collision, throwing
5, after the installation must be pressurized test, test pressure time of 30 minutes, hit 8-10KG, test pressure within 30 seconds under the pressure drop is not greater than 0.05Mpa, to work under pressure check, no seepage
6, the best pipe to the top, easy to repair, if you go underground, it is difficult to find leaks, inconvenient maintenance
remind:
If it is found that the wall paint is out of mold, the baseboard or the wooden floor is black and there is fine foam, the roof and the wall of the walkway wall are wet and seepage, the pipeline should be checked as soon as possible.

Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.
The SKF bearing catalogue lists a large range of designs, variants and sizes of deep groove ball bearings. Beyond our catalogue offering, the SKF Explorer deep groove ball bearings are customizable to offer advantages for applications with specific performance needs.
