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: The basement of submersible sewage pump outlet pipe installation need and flexible rubber joint is not installed? Can not?
- Gu called it a shock throat. It not only plays a role in noise reduction, but also protects the pump from the adverse effects of vibration. Rubber joints belong to GB products, the price is not expensive. Recommended installation.
- Q: What are the production processes and characteristics of high pressure rubber hose?
- According to the knitting process, the high-pressure hose is divided into high-pressure steel wire braided hose and high-pressure steel wire winding hose.
- Q: Method for inserting glass tube into rubber tube when assembling instrument
- If the outer diameter of the two glass tube to be connected is greatly different, the method can be used repeatedly to connect the glass tube into a channel or to be connected by a socket inserting method.In addition to the use of rubber sheathed outside the glass tube, can also be used for plastic pipe glass tube is sheathed, however, due to the elastic rubber pipe plastic pipe as well, so for sheathing plastic pipe with small diameter should be equal to the outer diameter of the glass tube.In addition, the use of plastic pipe sleeve glass tube should be adopted heat law, that is, the plastic pipe heating expansion and glass tube connection, and should not be rigidly inserted.Finally, because of the poor elasticity of the plastic tube, it is easy to age, harden and brittle, so when the glass pipe is connected with the plastic sleeve, the sealing measures must be adopted for the sleeve joint, and the sealing is usually done by gluing or waxing.
- Q: How do you remove the burrs on the rubber joint quickly?
- The thickness of the rubber joint burr than the thickness of the product is much thinner, so brittle speed than the speed burr brittle products quickly, in burr brittle and brittle products without this period of time can be hit by projectile projectile with frozen products deburring machine, thereby removing burrs in embrittlement.
- Q: The maximum number of joints for a rubber hose is no more than
- Shower hose, shower hose, two joints are nominal diameter of: 1/2 inch (4 thiophene) cylindrical pipe thread. Standard component. Hot and cold bath: take a bath with hot water before going to bed every day. The temperature of the water is within the limits of the body's tolerance. After washing, sleep in hot water for 15 minutes. After bathing was out of a sweat, after 3~4 minutes, and then into a basin of cold water or cold shower. Note that the hot and cold bath must be "hot before cold."".
- Q: How do the automobile rubber hoses combine with the quick couplings?
- The fluorine fast joint is aligned with the charging head on the air conditioner of the automobile, and can be connected by pressing lightly. Then the screw handle on the fast joint can be tightened reversely, so that it can be filled.
- Q: How can the hose of natural gas be connected to the water heater?
- It should be noted that when the nut is installed, pay attention to each nut must have plastic or rubber soft gasket, gasket must be flat, it plays the sealing role of the joint of the pipe joint.
- Q: How about rubber transfusion hose?
- The use of calender will glue paddle pressed into the middle, and then add the separant winding and made in accordance with the provisions of the production process requirements of winding hose cutting width.
- 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: How can the tightness of rubber tube and metal pipe joint be ensured?
- See how much your pipe diameter, diameter is around 10%, the metal pipe is inserted into the 2-3 rubber tube diameters, almost, don't worry, coupled with a hose clamp.
