Advantages of PP-R Equal Cross:


High Temperature Resistance: the maximum sustained working temperature is up to 70 °C,the maximum transient temperature is up to 95°C


Heat Preservation: low thermal conductivity which is only 1/1500 of brass pipe. And 1/250 of steel pipe.


Non-toxic: no heavy metal additives, would not be covered with dirt or contaminated by bacterium.


Corrosion Resistant: resist chemical matters or electron chemical corrosion.


Lower Installation Costs: light weight and ease of installation can reduce installation costs by as much as 50%over metal piping system.


Higher Flow Capacity: smooth interior walls result in lower pressure loss and higher volume than metal pipes.


Long Life: more than 50 years under normal conditions


Recycled and Environment-friendly

Q:How long is the welding time of the wire mesh composite pipe?
Pipe in the lower pipe, according to product standards shall be itemized examination, the standard does not meet the requirements, is strictly prohibited laying pipe.
Q:Is the PPR tube and the PPR composite pipe the same thing?
Composite pipe second advantages to the ordinary pure plastic PPR tube with the hot water to go for a long time will be bending (creep), affect the appearance, but after adding a layer of aluminum layer is not bent, with the more beautiful.
Q:Is there a steel plastic composite pipe in the PPR pipe now?
Stainless steel PPR: the outside is PPR, and the inner layer is made of stainless steel, just like the stainless steel tube inside the PPR tubeSteady tube PPR: the inner and outer layers are PPR, and the middle layer is stainless steel.
Q:What's the advantage of using a steel plastic composite pipe?
Long service life, more health, stronger bearing capacity, Tianjin source of plastic pipe for you to answer
Q:How to improve the bonding strength of polyurethane steel composite pipe
I recommend that you can see the double metal composite tube and memory stainless steel composite pipe, which is characterized by extremely high impact resistance, high pressure resistance, high temperature resistance, corrosion resistance, long service life and easy installation.
Q:PE pipe and plastic lined steel composite pipe like?
The pressure is consistent with the pipe pressure above the PE80 pipe but equal or lower than the PE100 pipe.
Q:Pingliang aluminum alloy lined plastic composite pipe Pb which is good?
PB pipe welding, material melting fast, common pipe welding Pb, poor quality control, if the welding quality is not good, is also highA waste of a Pb tube
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 utility model can effectively prevent the contraction of the inner plastic pipe, and because the thermal expansion coefficient of the two layers of internal and external plastic materials is greatly different, the inner plastic pipe is easy to shrink in the heating state. The inner reinforced plastic embedded steel pipe is made of convex, annular or reticular patterns on the inner wall of the galvanized steel pipe outside the outer layer, so as to increase the friction between the inner and outer pipes, and reduce the constriction of the inner plastic tube as much as possible. This particular structure has been granted national patent.
Q:PsP plastic steel composite pipe, good installation?,
The welding mode of the pipe should be electrothermal welding, so it is easy to weld.
Q:How can the stainless steel composite pipe be welded?
Because between the composite layer and the base layer is not easy to be welded together, so in the group before the first sealing. Welding should be welding method, using small amount of heat input so for sealing, we still used manual TIG welding. For the transition layer, the deposited metal composition is very complex. In order to make the alloy concentration gradient is not too large, we should choose the welding method with a larger heat input, then we use the electrode arc welding. As the base material is carbon steel, is a common material, welding process is very mature, so for the welding of the base welding arc welding, so as to improve the welding efficiency.
The company products are strictly produced as the standard of international, country and industry etc. And has already passed the test of national, provincial, municipal and other authority departments testing. Since the products put on the market, we own a good name in china and abroad.The products range has been changed from single into series. Now the company has become a high-tech modern enterprise of scientific research, development, production, marketing, trade and services.
