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 are the features of aluminum alloy lined plastic PPR composite pipe?
It is a kind of light and rigid pipe, because it is an outer aluminum alloy and is lined with PPR plastic.
Q:Is aluminum plastic composite pipe plastic pipe?
Refers to the plastic plastic composite pipe and aluminum pipe with multi-layer composite: the middle layer of the longitudinal weld of aluminum matrix composite material, the inner and outer layer with high and medium density polyethylene, polyethylene adhesive between the aluminium tube and the hot melt adhesive, five layer structure formed by one-step extrusion.
Q:Are beta -PPR tubes and aluminium plastic composite pipes one thing?
Beta -PPR tube is a kind of new PPR pipe manufacturers marketing, compared to the PPR tube has greatly improved in heat resistance, pressure resistance, aging resistance, the biggest difference is that in the premise of improving the service life and safety of the pipe wall, beta PPR tube thinner, greatly improving the inside diameter of pipe and the circulation. The utility model can be used in domestic water, and the increase of water quantity can improve the convenience and comfort of life, and the bathing is more pleasant, washing dishes and washing clothes are more convenient; and the heating efficiency can be greatly improved when applied to heating and the increase of water flow.
Q:Is the water pipe in the house made of PPR pipe or stainless steel pipe? What brand is better?
To the building materials City, you will find, water pipes are dazzling, PP-R pipe, PVC-U pipe, lining plastic pipe, stainless steel pipe, copper pipe and so on.The water pipe should be stable, watertight, and free from burstingWhat we call safety and durability is the occurrence of accidents that endanger life and family safety in the service life of the water pipe, which can not be used for a long time.
Q:How to connect the steel tube and the steel tube?
Electric melting connection is a composite pipe socket to electrofusion fittings, make embedded electric heat wire on the surface of the heating pipe. The pipe inner surface of melt generated melt, melt and fill the gap until the expansion pipe fittings, pipe appearance also produced two kinds of melt, melt each other together, cooling and forming after the pipe fittings are closely connected as a whole.
Q:What water pipes are of the best quality?
Aluminum plastic composite pipe is the earliest water supply pipe replacing cast iron pipe, and its basic composition should be five layers, namely, inside and outside are plastic, hot melt adhesive, aluminum alloy, hot melt adhesive, plastic.Aluminum plastic composite pipe has better thermal insulation performance, internal and external wall is not easy to corrosion, because the inner wall is smooth, the fluid resistance is very small, and because it can bend freely, so the installation and construction is convenient. As a water supply pipeline, aluminum plastic composite pipe has enough strength, but if the lateral force is too large, it will affect the strength, so it should be built as a pipe or buried in the wall, but it should not be buried in the ground. The connection of aluminum plastic composite pipe is card sleeve type, so it is necessary to check whether the connection is firm through strict pressure test during construction. Two is to prevent frequent vibration, so that the sleeve loose. The three is the length of the installation should be sufficient volume so as not to pull off.
Q:What about flexible composite pipes used in oilfields?
Flexible composite high-pressure pipeline is a kind of made of polymer composite materials with high strength, high pressure resistance, corrosion resistance, fouling, friction hydraulic oil pipe samples
Q:PP-R steel plastic composite pipe
Steel plastic composite pipe (Steel, plastic, composite)Pipe) is used in pretreatment, preheating, internal coating, leveling, postprocessing technology made in water supply galvanized plastic composite pipe, is the upgrading of traditional galvanized pipe, usually with threaded connections. The steel plastic composite pipe has many classifications, and can be classified according to the structure of the pipe, steel reinforced plastic composite pipe, seamless steel pipe, reinforced plastic steel composite pipe, hole net steel tape, plastic steel composite pipe and steel wire frame plastic steel composite pipe.
Q:Classification of stainless steel composite pipe railing in home decoration
Stainless steel is now popular, more and more industries and places to use stainless steel products, it brought us convenience. Then, we are in the decoration of the house, the use of stainless steel composite pipe railings, what classification and precautions, Xiao Bian with everyone to understand.Stainless steel railings are divided into: galvanized iron pipe, copper tube, stainless steel pipe, aluminum plastic composite pipe, composite pipe, PVC pipe.
Q:Plastic steel composite pipe buried pipe how to connect?
Steel plastic composite pipe, seamless steel pipe, welded steel pipe as the base pipe, painted with high adhesion, corrosion protection, food grade hygiene type polyethylene powder coating or epoxy resin coating. By pretreatment, preheating, internal coating, leveling, postprocessing technology made in water supply galvanized plastic composite pipe, is the upgrading of traditional galvanized pipe.
