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:Difference between non-standard rubber joint and national standard rubber joint
- Non standard is in shape and about the structure of standard atlas case material of flange thickness, flange ring thickness, diameter and thickness that relax the requirements, strictly speaking, these are unqualified products, of course, a certain extent to relax the standard does not affect the use, but too much to the influence of the relaxation of standards to use performance.
- Q:Pipe rubber shock absorber: flexible joints and flexible connections are not the same thing
- The soft connection is mainly composed of flexible body (bellows), net body and various forms of joint, compensating the deformation of the axial, transverse and angular directions of the absorption pipeline, and eliminating the stress.
- Q:Hydraulic hose joint configuration
- Self locking hose joint: a new type of hydraulic transmission, simple chemical package, easy maintenance and improved applicability. It has the advantages of convenient assembly and disassembly and wide adaptability. It is widely used in connecting all kinds of hose.
- Q:How often do the oil - resistant rubber pipes undergo atmospheric pressure testing?
- Low temperature bending test at low temperature: hose clamp on rigid torsion wheel diameter hose diameter 12 times, for 6 hours at a low temperature, twisted 180 degrees within 12s when the measured torque and the standard temperature measured torque ratio. Low temperature bending: hose clamped in the diameter of the hose within 12 times the torsion wheel, parked at low temperatures for 24 hours, in the 10s to reverse 180 degrees, check whether or not the internal and external plastic brittle fracture and damage. Test of low temperature brittleness measurement hose is the most simple specimen should be bent 90 degrees at low temperature, or a hose after freezing compressed 1/2 to see whether the embrittlement, another method is to use a certain weight of the heavy hammer falls freely, to see if the specimen embrittlement impact specimen.
- Q:The small hose attached to the grease gun is coarse or fine at the joint
- The joint on the grease gun is made of fine thread. The characteristics of fine thread are small pitch, small spiral angle, good self-locking, and not easy to loosen.
- Q:Does rubber hose drink from tap water? Is it poisonous?
- Galvanized steel pipe is divided into cold galvanized pipe, hot galvanized pipe, the former has been banned, and the latter is also advocated by the state for the moment, can be used. In 60s and 70s, developed countries began to develop new types of pipes, and galvanized pipes were banned. China's Ministry of construction and other four ministries have also issued a civilization, from two, 000 years since the prohibition of galvanized pipe, the current New District cold water pipe has rarely used galvanized pipe, and some of the hot water pipe is galvanized pipe.
- Q:Can the high-pressure rubber hose be followed by water pipes? Will it be poisonous?
- The problem should also not large, if it is stored for a period of time in the yard, first put best water again, after all, is not a food container rubber material, inside some substances will dissolve gradually, and there is a water purifier water generating reaction of some harmful substances.
- Q:Is there a tolerance standard for rubber tubes in length?
- Just think, in the use of the tube, is the important dimension of diameter and wall thickness of the pipe, a little a little long, short should not affect the use, especially the rubber tube, right?! so imagine, rubber tube should not have standard tolerances in length (requirements).
- Q:How to remove hose odor?
- When rubber is peculiar, it can be scrubbed by hydrogen peroxide. After drying, the odor will disappear. Or with waste tea sent to rubber products, tea has the role of adsorption odor.
- Q:Is the electric water heater well connected with the metal hose?
- It's better to use a metal hose.Good resistance to high temperature.In addition, the metal hose is better tolerated.It is more durable and difficult to break than hose.
