That is, PE-RT pipes.

The difference between PE-RT II pipe and PE-RT II pipe is different in high temperature resistance level, PE-RT pipe belongs to low-temperature pipes with a service temperature of less than 70 °C, and PE-RT II pipes are used for high-temperature hot water pipes with a service temperature of 70-95 °C; In the low-temperature piping system, the diameter of PE-RT pipes is mostly DN20-110mm, and the diameter of PE-RT II pipes in the high-temperature hot water piping system is DN16-500mm; Generally, there is a logo of "aluminum alloy lined with plastic PE-RT composite pipe" or "aluminum alloy lined with plastic PE-RT II composite pipe" on the pipe, to take a screenshot for you to see.

In November 2022, the GB T41494-2022 "Aluminum Alloy Plastic-Lined Composite Pipes and Fittings" standard has been promulgated.

How to answer this, can only be relatively speaking, because the difference between the pipe design and raw materials of each company is not very contrasting, and the temperature resistance and application effect cannot be generalized. To be precise, this is the difference! First of all, it is necessary to analyze some factors that affect the quality of pipelines to delineate a standard

On the basis of pure raw materials, ASAK is an example, and there is aluminum alloy lined with plastic P

Ordinary aluminum alloy lining means that the outer aluminum tube is not anodized, and after anodizing, it is an oxygen-blocking aluminum alloy lined composite pipe.

Yes, it's just that the temperature used is different.

The biggest difference between aluminum alloy plastic-lined PERT composite pipe and aluminum alloy plastic-lined PPR composite pipe is: the inner liner pipe is different, one is PERT pipe, the other is PPR pipe, in fact, it is the difference between PERT pipe and PPR pipe, PERT - heat-resistant polyethylene, is a modification of polyethylene PE (is a copolymer of polyethylene and octene) is the American chemical giant Dow Company in 2003 successfully developed, PERT has all the physical properties of polyethylene (PE). It has good heat resistance and is used in hot water piping systems. PPR belongs to the PP polypropylene category, which is an improvement of PP and the scientific name is type III polypropylene, which is a good pipe for cold and hot water piping system.

The biggest difference between PERT and PPR :p ERT has super low temperature resistance -40°C, PPR is very general, when it is below 5°C, it will produce vitrification under the impact of external force, and it will occasionally freeze below 0°C in winter, which is the physical property of PPR, but PERT will not. Of course, PERT** is higher than PPR**, and PERT temperature control is very important when hot melting, 255-265 °C is the best temperature (the hot melt process is very demanding, and the construction personnel should pay special attention to the special hot melt machine in addition to the temperature), and the PPR hot melt temperature is 270-280 °C (the construction process is simple, and the construction personnel will install it).

Suzhou Tongbao Pipe Industry "The Difference between PERT and PPR".

Hello, it is that the raw materials of the lining are not the same.

One is pert material, the name of the raw material is high-temperature resistant polyethylene, which is more excellent in high-temperature resistance! Pert pipes, generally used as geothermal pipes in China.

One is PPR material, the name of the raw material is polypropylene, which is mainly used for drinking water pipes in domestic writers.

You can choose the corresponding lining according to your needs, and I hope to help my friends.

Hello, aluminum alloy lined with plastic PE-RT II composite pipe is a new type of environmentally friendly pipe, which is mostly used for building water supply and heating.

Aluminum alloy plastic-lined PE-RT composite pipe is a kind of two-layer structure pipe composed of aluminum alloy pipe with outer pipe and PE-RT plastic pipe with external stress. The characteristics are: luxurious appearance, 50 years maintenance-free, improved heat resistance, pressure and corrosion resistance, green environmental protection, etc., suitable for domestic hot and cold water, natural gas pipelines, air conditioning pipes and so on.

Aluminum alloy plastic-lined composite pipes can be divided into the following pipes according to the lining material: aluminum alloy plastic-lined PPR pipe, aluminum alloy plastic-lined PE-RT pipe, aluminum alloy plastic-lined PE-RT pipe, aluminum alloy plastic-lined PB pipe, aluminum alloy plastic-lined PE gas pipe. Aluminum alloy plastic-lined PE-RT pipe is an upgraded version of aluminum alloy plastic-lined PE-RT pipe, aluminum alloy plastic-lined PE-RT pipe has better high temperature resistance, normal is below 95, ordinary aluminum alloy plastic-lined PE-RT pipe can not withstand such a high temperature, about 60 below.

1.The material is different, one is PPR material and the other is PE-RT material 2The aluminum layer is different, the aluminum layer of the aluminum-plastic tube is in the middle, and the aluminum layer of the steady-state tube is basically almost to the outside, covered with a thin layer of PPR.

3.Connection method Wentai pipe hot melt connection, PERT aluminum-plastic pipe can be hot melt connection, can also be connected with copper pipe fittings.

4.Stability after hot melt The molecule of PPR is relatively stable, the stability after hot melt is relatively high, and the stability of Pert is poor.
