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 glue can glue rubber tube?
- Location: in the face and then drop a little sticky rubber JL-330 iron speedglue, immediately bonded, and keep to the hardening, hardening time ranging from a few seconds. About 30 minutes to reach practical strength, 24 hours after the maximum intensity.
- Q: Could you tell me the maximum pressure that the hose can bear?
- Production process with pressure hose hose to withstand the enhancement layer material has a great relationship with the enhancement layer, the enhancement layer of the same level, generally the larger diameter bearing capacity is small, the enhancement layer is cloth or steel wire line and the enhancement layer is also different. Select the hose you want according to your requirements. The hose pressure is 4 times the normal pressure
- Q: What is the essential difference between silicone tube and rubber tube?

- Q: Is the rubber pipe joint installed in the middle of the pipe and pump to absorb the shock?
- Control the noise produced by parts of machinery, equipment, and equipment. The pump foundation of the new pump house should adopt heavy weight to prevent vibration from producing noise. Vibration isolation should be set up with rubber vibration isolating pads to reduce vibration noise. Each pump unit shall be provided with a foundation to prevent resonance. Use "soft" connection as far as possible in the suction pipe and pressure pipe of the pump. Periodic maintenance problems, such as packing leakage, equipment parts loose, serious wear and tear of equipment parts, mechanical vibration and so on, should be repaired in time, thereby reducing noise.
- Q: Must the hose for the cooker be made of oil resistant rubber hoses?
- When the gas combustion equipment and gas pipeline for hose connection, the design should meet the following requirements: (1) the burner of household gas stove and laboratory use, the connecting hose length should not exceed 2m, have no interface; (2) industrial production with mobile gas burning equipment, the connecting hose the length should not exceed 30m, the interface should not exceed 2;...
- Q: Single ball chloroprene rubber flexible joint, Shanghai Song Jiang rubber ball joint manufacturer where?
- It is divided into 3 kinds: flange type, fixed flange type and thread type by connection. The structure can be divided into 5 kinds: single sphere, double sphere, different diameter body, bent sphere and wind pressure coil.
- Q: Method for connecting glass tube and rubber tube
