Product Description:



Work for cold and hot water, gas


MAX.temperature: 95 degree

Working presure: 10 bar


Pex-al-pex pipes are designed with special polythene both inside and outside, being clean


and smooth. The aluminum layer in the middle is of 100% insulation. 




1) Specification: Φ16 – 32mm


2) Non-toxic, anti-corrosive


3) Light weight, strong mechanical properties and thermal-resistant ability


4) Low fragile humidity and long using life


5) Low flowing resistance inside the pipe, scaling can rarely happen


6) The fluids cannot be contaminated. Effective diameters are big


7) Oxygen is 100% isolated and infiltration is thoroughly prevented. In case they are used as shielding materials for telecommunication circuit, magnetic interference can be prevented 


8) Anti-static, and suitable for gas and fuel transportation


9) Can be bended or straightened without restriction

Q:Process technology of aluminium alloy lined plastic composite pipe
BM type barrier screw and IKV forced feeding system are adopted to ensure good plasticizing property. The assembly line pipe adopts non chip cutting, and the end of the pipe is smooth, so as to avoid the phenomenon that the stress concentration in the gap is caused after cutting off.
Q:What is the difference between HDPE pipe and aluminum plastic composite pipe?
Also known as the PAP pipe plastic pipe, is composed of a central longitudinal welding tube, inner and outer layer of polyethylene plastic and between layers of hot melt extruded compound into a new type of pipeline, classified by use of ordinary drinking water, high temperature pipe, gas pipe, pipes, features and applications are as follows: the aluminum-plastic composite pipe with the ordinary drinking water application scope: white L logo, living water, condensate water, oxygen, compressed air and other chemical liquid pipeline. High temperature resistant aluminum plastic composite pipe: red R mark, mainly used for long-term work, water temperature of 95 degrees of hot water and heating pipe system. Gas aluminium plastic composite pipe: Yellow Q mark, mainly used to transport natural gas, liquefied petroleum gas and gas pipeline system.
Q:What is the connection between the steel plastic composite pipe, plastic pipe?
The plastic pipe is a steel plastic composite pipe, epoxy resin coated steel pipe and polyethylene coated steel pipe two.
Q:How to process and install the steel plastic composite pipe?
Lida brand steel plastic composite pipe is divided into light and ordinary two, according to the use of cold water pipe, water pipe, according to nominal diameter 15 Phi 110, specific representation representation, just as the galvanized pipe and plastic steel in front of cold water, hot water.
Q:PP-R is it a steel pipe, a plastic composite pipe, or a cast iron pipe?
PP-R pipe, PP-R pipe, also called type three polypropylene pipe, has the characteristics of light weight, corrosion resistance, no fouling, long service life and so on. PP-R pipe manufacturers are more, quality differences exist, once the leakage, huge losses, it is recommended to choose well-known brand products, and select professional construction team.
Q:Aluminum alloy lining plastic PPR composite pipe performance advantages?
Aluminum alloy lined plastic PPR composite tube pressure resistance, anti-aging: not only gorgeous appearance, but more importantly, it can effectively resist ultraviolet radiation in the sun, anti-aging, enhanced pipe service life, suitable for Ming zhuang. 2. linear expansion coefficient, longitudinal shrinkage rate low 3. excellent oxygen impermeable performance of 4. easy to install 5. scope: powerful functions used in the building hot and cold water supply piping system suitable for heating and air-conditioning supply and return water pipe system is applicable to all kinds of food hygiene, drinking water and medicine preparation pipeline system is applicable to all kinds of chemical agents, the air pressure pipeline system... 6.... Free maintenance: stable flow - the inner wall is smooth, no scaling, small transmission resistance and stable flow. Heat preservation and energy saving - low heat transfer rate, heat insulation, energy saving effect 7., applicable to domestic hot and cold water, natural gas pipeline, air conditioning pipe
Q:Can PSP steel plastic composite pipe be used in hot water system?
PSP pipes should not be used in hot water systems. Because manufacturers are produced in accordance with cold water standard pipe, it can not be used in hot water system.
Q:How can the stainless steel composite pipe be welded?
The backing layer adopts melt-through bead welding process, the welding position is generally fixed, difficult to weld, welding layer is composite pipe to meet the highest quality requirements of the process, the technical level of the welder must have a strong and high sense of responsibility. Must be on the inside of the pipe before welding, argon weld filling 99.99% time tester oxygen content from the source of deep groove gap gas extraction measurement of internal oxygen tube, when the oxygen content is less than 50ppm at the start of the bottom in order to ensure the welding quality by tungsten arc welding by self to symmetry, before welding sealing; welding welding layer was burnished.
Q:What is the plastic lined composite pipe?
Plastic composite pipe inner surface is lined with plastic composite pipe, also called plastic lined steel composite pipe.It is based on the ordinary carbon steel, lined with plastic, cold drawn by composite or rotational molding.
Q:Construction technology of PE steel plastic composite pipe
1. before installation, check the groove to meet the installation requirements, and then check the appearance of the pipe there is no obvious sag, cracks, scratches, scratches, found quality problems, timely replacement.In 2., three links, elbow, reducer etc. fire hydrant with C20 concrete concrete pier, brick pier reinforcement flange valve.3. PE water supply pipe and metal pipe, valve, fire hydrant connection, must use plastic steel transition joint or special flange connection.4. the exhaust valve shall be installed at the uplift part of the pipeline or on the uphill side to reduce the impact of the water pressure on the pipe. The ratio of the pipe and exhaust valve is designed to be 1:8.5. because the PE pipe itself has good flexibility and flexibility, all pipe installation has not considered the installation of expansion joint.
