Rifeng pipe adopts innovative environmental protection materials, and the smoothness of inner and outer walls is twice that of ordinary PPR pipe. It is not easy to scale, has strong antibacterial ability and has the characteristics of pressure resistance and high temperature resistance. Under the laboratory study of water temperature 65 degrees Celsius and pressure 10 kg 1MPa, the service life can reach more than 50 years.
Rifeng tube products are of excellent quality, which strictly conform to GB/T5836. 1-2006 and GB/T5836.2-2006, and meet the national quality standards. Long service life, good aging resistance of pipeline and excellent corrosion resistance to inorganic acid, alkali and salt.
Structurally, a new type of large arc bending design is adopted, which has excellent tensile strength, strong impact resistance and high pipeline safety factor, so that we can effectively reduce the formation of water hammer and avoid pipeline impact to a great extent.
It has a unique dovetail groove structure. Whether it expands with heat or contracts with cold, the combination and sealing between pipes are good, which can prevent leakage. In addition, the inner wall of the pipeline is lubricated, and the design of pipe fittings is fine, which can complete the smooth lubrication of the joint between the inner and outer surfaces and make the drainage smoother.
Good flame retardancy, 45-degree chamfer design, standard outer diameter and thick inner diameter, which is convenient for welding and fusion. Moreover, its oxygen index is high, and it will extinguish itself if it leaves the flame, so there is no fire control scruples.

Matters needing attention in purchasing Rifeng tube:
1. In order to protect your rights and interests, you must go to a regular Rifeng store before buying. Rifeng authorized dealers have Rifeng unified logo facade and authorization certificate.
2. "Rifeng" and "Fengfeng" trademarks have opened anti-counterfeiting inquiry systems for product codes in Ming Museum and official website to protect users' rights and interests.
3. The merchant asks for the after-sales service card, and keeps the card and relevant purchase vouchers. Rifeng has a unified product service card.
Correct trademarks and purchase vouchers are important basis for quality assurance.
Matters needing attention in the use of Rifeng tube:
First, pipes that can be frozen should be kept warm.
2. Avoid long-term ultraviolet radiation to prevent rapid aging, and adopt ultraviolet-resistant black pipes or take other protective measures (wearing insulation pipes can kill two birds with one stone).
Third, the outlet temperature of some gas water heaters may be overheated, so it is necessary to use metal hoses for intermediate transition, and then connect with Rifeng pipes.
Four, after installation, water pressure test should be carried out according to the relevant construction specifications to prevent water leakage and water leakage caused by improper installation.
PP-R pipe: the test pressure of cold water pipe is 1.5 times the design pressure of cold water piping system, and not less than 0.9MPa；;
The test pressure of the hot water pipe shall be 2.0 times of the design pressure of the hot water pipe system and not less than1.2mpa..
Verb (abbreviation of verb) suggests using Rifeng pipe fittings (because the outer diameter of pipes from different manufacturers will deviate from the inner diameter of pipes, which will easily lead to poor welding. According to the kilocalorie test, Rifeng pipe has a thick inner diameter and a standard outer diameter. The melting point of the outer layer and the melting resistance of the inner layer are suitable and the welding effect is good. Copper fittings with dovetail grooves).
