polypropylene random Pipe
PP-R (polypropylene random) tube called three polypropylene random copolymer polypropylene pipes and PPR pipe, with saving energy and materials, environmental protection, high-strength lightweight, corrosion-resistant, smooth wall ,non scale, easy construction and maintenance, long life and other advantages;widely used in building water supply and drainage, municipal water supply and drainage , city gas, electricity and cable jacket, industrial fluid transport, agriculture and irrigation. It is a water supply pipeline currently used in most home improvement projects .
In addition to general plastic tube with a light weight, corrosion-resistant, non-scaling, long life , but also PP-R pipe has the following main features:
1.Non-toxic and health. materials molecule of PP-R only has carbon and hydrogen elements, no harmful toxic elements, reliable health, not only for the hot and cold water pipes but also can be used to clean drinking water systems.
2.Thermal insulation. thermal conductivity of PP-R pipe :0.21w / mk, only 1/200 of steel pipe .
3.Good heat resistance. Vicat softening point of PP-R pipe is 131.5 ℃. The maximum operating temperature of up to 95 ℃, to meet requirements of hot water system in building water specification
4.Long service life. In conditions of working temperature 70 ℃, and working pressure (PN) 1.0MPa , the service life of PP-R pipe up to 50 years (provided that the pipe must be S3.2 and S2.5 series above); at room temperature (20 ℃) service life of up to 100 years.
5. Easy to install, reliable connection. PP-R has good welding properties, pipe and tube can melt and fused connections, easy installation, reliable joint, its strength joints greater than the strength of the pipe itself.
6.Recyclable . through clean and recycling after crushing ,PP-R waste is used in production of pipe and fittings . Regrind amount does not exceed 10% of the total, does not affect product quality.

- Q: Access toilet water inlet hose joints, how to repair water?
- You try to put the connector aside, hold some force in the toilet hole, or add a person to press it with your hand, then swivel the pipe joint and maybe open it.
- Q: Why should the high pressure hydraulic tube peel off the outer skin?
- Reasons for stripping:1, the inner diameter of the sleeve is a standard series, and a little rubber hose is not suitable for sizing.2, after stripping, the sleeve can be directly pressed on the steel wire layer, the connection is reliable, and it is not easy to pull out.
- Q: What is the function between the rubber pipe joint and the installing pipe?
- The inner seamless seamless rubber joint prevents the corrosive medium from eroding the inner wall of the rubber joint and improves the service life in the high temperature resistant, acid resistant and oil resistant pipes.
- Q: What's the difference between the rubber hose joint and the stainless steel hose joint?
- 1, high water use of this product, the pipeline must be fixed or fixed support bracket, otherwise the product should install anti pull off device. The force of fixed support or bracket must be greater than the axial force, or should install anti pull off device. And because the metal hose pressure resistance better, do not need to install.2, you can choose to use according to their working pressure: 0.25MPa, 0.6MPa, 1.0MPa pipe, 1.6MPa, 2.5MPa, 4.0MPa of the flexible rubber joint, high pressure pipeline equipment, we recommend that customers choose chungha brand stainless steel metal hose, according to the different use of the environment and the size, our biggest can withstand up to 300KG, customers can also ease of use.
- Q: Can the rubber hose for the LPG cooker and gas cooker be general?
- Whether the gas stove is the use of natural gas or liquefied gas, artificial gas, all can use the rubber tube, need to pay attention to is the pipe diameter and gas stove pipe diameter should be consistent, but also to the fixed ring frame with rubber tube, rubber tube is also too long existing problem of aging time, while the gas is there is a certain danger, recommend regular replacement of rubber tube
- Q: What are the methods of sterilizing rubber hoses and Perspex?
- Plexiglass products, we are placed on super clean bench, UV irradiation above 30min. Sometimes it takes time to wipe with 60% alcohol cotton ball.
- Q: Toilet hose and water tank joints leaking, how to repair?
- No rib sleeve, the use of pipe outside the buckle fixed, sealed, may be the aging of the tube, buckle clamping difficulties and other reasons. If the pipe is aging, you can cut or replace the tube in the aging part. It is difficult to buckle and clamp, so you need to change the buckle.
- Q: How to replace natural gas hose? Steps?
- Replace the natural gas hose first pressure relief, and resolutely put an end to the operation with pressure;According to the connection way of the hose, if it is O ring sealed, just tighten it directly;If it is cone thread, it can be wrapped with raw material tape or sealant.
- Q: What material is the rubber joint used in the desulfurization pipeline? What's the difference?
- Three yuan EPDM rubber joint can be used, PN4-6 is no problem. Generally, the desulfurization pipeline is weak acid base,
- Q: In long-term high temperature environment, silica gel tube and three yuan ethylene propylene rubber hose which is good durability?
- In long-term high temperature environment, silica gel tube and three yuan ethylene propylene rubber hose which is good durability?
