1. Common problems of PPR pipe: The common problem is water leakage. In addition to purchasing water pipes, installation specifications are also very important; pipe fittings should not be tightened too tightly to avoid cracks and water leakage; winter construction should avoid stepping, knocking, collision, throwing Fall; the water pipe should go to the top for easy maintenance. If it goes underground, it is difficult to find water leakage and it is inconvenient for maintenance; when using ppr pipe fittings with metal threads, use a foot seal to avoid water leakage at the thread; 4~5 cm at the end of the pipe should be cut After installation, pressurization test is carried out. The pressure test time is 30 minutes, and the pressure is 8-10kg. The pressure drop under the test pressure is not more than 0.05mpa within 30 seconds, and the pressure is reduced to the working pressure for inspection.
2. Details of PPR pipe: The pipe is made of 100% ppr raw material, with smooth appearance, logo, and anti-counterfeiting logo on the accessories; service life: product quality assurance is 50 years, and inferior products are only 5~6 years; thermal expansion and cold contraction: it is Softening; Toughness: Good ppr pipes have good toughness and can be easily bent into a circle without breaking, while inferior pipes are brittle and break as soon as they are bent.
