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 are the gas hoses?
- The stainless steel is expensive, 40 yuan set.The rubber is cheap, 10 yuan a set.Where do you come from? I don't know. In our Shanghai gas, this price includes the labor cost of the installation to you. In other words, fix it directly for you.
- 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:How to make a rubber tube requires flow
- The characteristics of the rubber tube has physiological inertia, UV resistance, ozone resistance, resistance to high temperature (-80 to 300), high transparency, strong resilience, resistant to compression permanent deformation, oil resistance, impact resistance, acid and alkali resistance, wear resistance, flame resistance, voltage, conductive properties.
- Q:How to determine the parker381 hose joint?
- PARKER hose connector specifications: 1/4 "to 2", the connection form of DKO 24 cone, American NPT taper thread, JIC37 degree flared, ORFS American plane seal, JIS60 cone, JIS30 degree flared, SAE flange etc.. It can be divided into three series: detachable, buckle pressing and Push-Lok. The detachable series hose joint does not need special equipment when it is assembled, so it is easy to operate. It is especially suitable for field operation and can be reused. But because of the high price, fewer customers are used. Buckling type series high voltage because the connection is reliable and widely used, but the processing assembly need to withhold special equipment, so the majority of customers directly buy hose assembly. Push-Lok series are suitable for low voltage applications. They are widely used in automobile production lines because of their rapid assembly and disassembly, easy maintenance and replacement. They are also widely used in the die industry.
- Q:HDPE double wall corrugated pipe joint shall be made of elastic sealing rubber ring and socket joint interface. What are the requirements for rubber ring joint?
- The interface method should be carried out according to the following procedures: DN400 pipeline and below, by a man with a cotton rope hook is installed pipe socket, the other one with a long lever oblique insertion based cross baffle against the tube end of the center position, and then forced the tube slowly into after the installation of HDPE double wall corrugated pipe the pipe socket to a predetermined position; more than two sets of DN400 pipeline by hand hoist will pull in pipe section. When the interface is closed, the spanner on both sides of the pipe section shall be pulled synchronously, so that the rubber sealing ring is properly positioned and is not distorted or not falling off.
- 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:How often do the oil - resistant rubber pipes undergo atmospheric pressure testing?
- Suction flat test: in the 1min vacuum, after maintaining 10min, with diameter of 0.9 times the diameter of the hose rolled over, check the degree of collapse of the hose. Some standards used to measure the rate of change in the outer diameter of the hose to indicate the extent of deformation of the hose.
- Q:Are the bridges, bellows and rubber tubes drawn out or are they drawn only? And the bellows are tensioned with the steel strand?
- The bellows are buried inside the component and do not need to be pulled out. Through reinforcement, only pre-stressed, without tension bellows. When tensioning anchor is completed, grouting work is necessary.
- Q:Method for inserting glass tube into rubber tube when assembling instrument
- The sleeve method of different outer diameter glass tube should be determined according to the size of the outer diameter. If the outer diameter of the two tubes is not big, then the rubber tube with the same inner diameter can be connected. When connecting to the rubber sleeve in the larger outer diameter glass tube, the specific method, with a diameter from one end of the rubber tube of the same stick (such as chopsticks) inserted into the connection end to the rubber tube, rubber tube set in reverse, then the larger outer diameter glass tube against the wooden stick. The rubber hose forward turning sleeve on a glass tube, stick out.
- Q:What's the metal hose for fire fighting?
- 1 the metal hose is made of 1Cr18Ni9Ti stainless steel, and has strong corrosion resistance.The 2. hose tube is made of thin wall stainless steel tube. It has strong flexibility, flexibility, strong bending and vibration resistance, and reinforced protection of woven mesh sleeve, so that it has higher bearing capacity.The connection of the ends of the 3. flexible pipes can be made into other connecting ways except the thread and the flange standard, so that the connection and the use are convenient.4. the product is not only suitable for mating with rotating joint, but also widely used in soft connection of many kinds of fluid medium transportation.
