Product Description:

PPR pipe is officially known as the random copolymerized polypropylene pipe, is currently Jiezhuang works by a water supply pipe at.

The hot melt technology of PPR pipe interface, between the pipe completely fused together, so once the installation of pressure test, will never Water Leakage, high reliability. But this is not to say that PPR pipe is not defective hose,high temperature resistance, pressure resistance is little worse, long-term working temperature should not exceed 70 ℃; each segment length is limited, and must not be bent construction, if the pipeline laying long distance or the corner, in the construction will be used a lot of joint; pipe cheap but accessories relatively high prices. From theperformance of speaking, PPR is the higher price of pipe, so become the first choice for home improvement materialswater reform.

The market sales of PPR pipe mainly has two kind of colors, white and grey, why there is this difference, the dealer's answer is the raw material of PPR particles caused by different.

In general, water and electricity transformation, the original water can replace, Jiezhuang companies and businessesto install the PPR tube with hot water pipe in the proposed fitting, even the cold water flowing through the place withhot water pipe. They say is due to the technical parameters of the hot water pipe is higher than that of the cold water pipe, and the price difference, so the water transformation with the hot water pipe. Another is the fact that even if youwant to market is also very difficult to buy buy cold water, because cold water pipe supply only tooling market, notsupply Jiezhuang market.

Diameter PPR pipe diameter can be from 16mm to 160mm, Jia Zhuang, mainly use the 20mm, 25mm two(respectively, commonly known as 4 in, 6 in, 4 of which work) to more.

PPR pipe with plastic pipe features of light weight, corrosion resistance, no scale formation, long service life, but alsohas the following main features:

1, non-toxic, health. Raw material molecular PP-R only carbon, hydrogen, no toxic harmful elements exist, health can be *, not only for the cold and hot water pipes, but also can be used for pure drinking water system.

2, energy-saving insulation. Thermal conductivity of tube is 0.21w/mk PP-R, only for the steel 1/200.

3, good heat resistance. PP-R VEKA softening point 131.5. The maximum operating temperature up to 95, canmeet the building to use the hot water system, drainage standard.

4, long service life. PP-R tube in the working temperature is 70 ℃, working pressure (P.N) under 1.OMPa conditions,the service life of up to 50 years; room temperature (20 ℃) with a life span of 100 years.

5, convenient installation, reliable connection. PP-R has good welding performance, pipe, pipe heating and welding connection, convenient installation, the joint can be *, the joint strength is greater than the strength of the pipe itself.

6, the material Recyclable utilization. PP-R scrap through cleaning, crushing recycling in pipes, pipe fittings. No more than 10% of the total amount of recycled material, does not affect the quality of the products.

Q:What is a composite pipe?
The composite pipe, as the name suggests, is composed of two layers (including two) of a pipe pipe by some above multilayer structure and processing technology of the compound into the Aluminum Alloy as our factory production of plastic composite pipe, the outer pipe is Aluminum Alloy tube, inner tube for thermal plastic pipe, two layer structure the pipe through prestressing Composites
Q:What's the quota for plastic lined steel pipes?
Plastic lined steel pipe, also known as the steel plastic composite pipe, tube with welded steel pipe galvanized seamless steel pipe, wall, removal of weld reinforcement, lined galvanized pipe with inside diameter of food grade polyethylene (PE) pipe, polyethylene liner thickness requirements in line with the CJ/T136-2007 standard, finally after a certain period of time after heating compression molding, upgrade type of traditional galvanized pipe.
Q:Rpap5 butt welded aluminum plastic composite pipe and PB pipe which is good?
The same PPR tube also has special belt wire fittings, a hot PPR, a head rest outside the wire or wire. Wow and iodine spy Yan paid winter riveting inclined towersThen the two are threaded, hoping to help friends
Q:What's the difference between inner ribbed plastic lined steel pipe and ordinary lining plastic pipe? What are the production processes of plastic lined steel pipes?
The connection is reliable and convenient, the use of high pressure reinforcement bars embedded in plastic lined steel pipe with a clamping ring type quick connector connection, not in steel tapping, convenient installation, and the self-locking pipe joint and good sealing performance, can ensure the effective use of 2.0Mpa in the high working pressure.
Q:PsP plastic steel composite pipe, good installation?,
Finally, in the installation process, it is best to find a technician in the next to conduct a supervision, so as to avoid pipe problems later.
Q:What's the difference between a steel plastic composite pipe and an aluminum plastic composite pipe?
Steel plastic: carbon steel pipe lining PE or coated with PE, that is polyethylene, good rigidity, high pressure resistanceAluminum: aluminum tube lining PE or coated with PE, that is polyethylene, good resistance, non resistance to high pressurePlastic steel composite pipe generally refers to the single side of the composite pipe, as well as double-sided, single, rarely used.
Q:What are the advantages of stainless steel lined pipes?
Because of the two outer layers are metal materials, so its compressive strength, impact resistance, high tensile strength, high elongation, high elastic modulus, low coefficient of thermal expansion, especially suitable for high-rise building water supply pipe and branch pipe burying and use.
Q:Is the plastic lined steel pipe the same as the PSP composite pipe?
PSP steel plastic composite pipe base material is steel, and plastic coated PE/EP, the surface of the plastic coated steel.
Q:The difference between aluminum pipe and PPR pipe
PPR pipe is commonly known as "hot melt pipe", through the construction of special heaters for pipe and pipe connection, waterproof leakage performance, corrosion resistance, impact resistance and heat resistance and so on. The theory of relative service life than aluminum tube.
Q:PSP plastic steel composite pipe and lining plastic composite pipe can be used instead?
The steel plastic composite pressure pipe is a new type of composite pipe made of metal and plastic. The welded steel pipe is used as the middle layer, the inner and outer layers are polyethylene plastics, and the special hot melt adhesive is used to form a pipe through the extrusion forming method.
