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:What's the rubber sleeve of the expander?
- Expansion rubber flexible joint, installation of the flange sleeve telescopic device.
- Q:Rubber tube in the production process need to wrap cloth, in order to finalize the design, I want to know what cloth is winding cloth, what is the specification, please god!
- Polyamide (nylon) water cloth with high strength nylon filament as raw materials, the introduction of the Swiss high-speed shuttleless loom woven, has the characteristics of high density, fine texture, smooth surface, not deformation, surface sulfide even shrinkage, fracture strength, long service life, make good products and rubber skeleton material good adhesive effect the appearance of black, wove neat, shallow indentation.
- Q:What is a rubber core pulling method?
- For short component hole, a hose can be used to bend through two parallel holes; if it is used for retaining hole of long component, the two hoses of anchor can be connected by iron sheet sleeve. The length of the bushing should be 400 - 500mm, and the inside diameter should be 2 - 3mm larger than the outer diameter of the hose. The fixed position of steel derrick hose available, spaced not more than 0.5m, and fasten with steel skeleton.

- Ventilation ducts and exhaust fans are for people or things, and the noise of vibration is unbearable for people or things.
- Q:How can we prevent the aging of rubber tubes?
- The second is the design of the structure of the rubber products (especially damping products), has a great relationship between aging and fatigue, should avoid stress concentration! If the product is good has been produced to prevent aging, more trouble! Can be sprayed on the rubber surface, spraying insulation polymer.
- Q:The pipe of the gas water heater is buried in the wall. It is made of nylon tube and rubber tube. Is it possible to use rubber tube?
- After so many years of consulting, you are the first to ask the hose through the wall. In real life, there are many hoses that go through walls.
- Q:Why are the lengths of the household combustion equipment linked to the gas pipe hose no more than 2 meters?
- Avoid prolonged accumulation of gas combustion
- Q:Hydraulic quick change joint (external thread) how to connect and seal with hose? Do you need a transition joint?
- 1. The inner and outer threads of the quick connector are to be connected with the hose when the transition joint or adapter is used.2, no matter how many kinds of hose connections, according to the types of hose joints to choose how to transition joints.A, if the hose is ordinary water, it should be used as a transition joint, in the head of teeth, a plug pipe, and then use the fixed clamp.B, if both ends of the hose are internal, then the transition joint should be one head and one outer tooth.C, if both sides of the hose are external teeth, then the transition joints should be, the internal teeth through.
- Q:Between the two flanges in the middle of the rubber tube, what is the name of the connection?
- Rubber flexible joint is also called rubber flexible joint, flexible rubber joint, flexible rubber joint, rubber shock absorber and so on.
- Q:What kind of material does hose screw protection cover have? What are their advantages and disadvantages?
- The utility model relates to a pipe protecting sleeve, which is a new product replacing the traditional metal protecting spring used for the protection of traditional rubber hoses. Alias: hose sheath, rubber tube outside protection special nylon spiral sheath, etc..
