Pe-rt PIPE
Pe-rt tube (also known as Pe-rt tube) is a water pipe manufactured using a high temperature resistant reinforced
polyethylene material, non-crosslinked polyethylene. This material has：
1.High temperature resistance, which can be used for hot water transportation below 60 degrees Celsius for a long
time.
2.It has the characteristics of low temperature resistance, which is suitable for transportation and construction in
low temperature environment.
3.Good flexibility, good thermal creep resistance and long-term hydrostatic resistance.
Therefore, it is very suitable for use in piping systems, reducing the number of connection points.

PEX or PE or PERT layer
AL aluminum layer
PEX or PE or PERT layer PAP pipes combine the advantages of metal pipes and plastic pipes. Among
them, PEX-AL pipe has high strength and high temperature resistance, which
meets the design requirements of water supply temperature of 95℃, and is
also an excellent pipe for high temperature radiator heating.
Application Field
Polygon PEX-Al pipe is a three-layer composite pipe that combines the advantages of a metal and plastic
pipe and eliminates the disadvantages of both materials at the same time.
Good oxygen resistance: the aluminum layer and all metal fittings can completely isolate the penetration of
oxygen, which can not only greatly reduce the breeding of microorganisms in the pipeline system, but also
effectively extend the service life of the metal components in the heating system.
Aluminum belt interface: butt welded aluminum belt, smooth welding, uniform pipe wall, good tube roundness.
Heat and pressure resistance index: PEX aluminum pipe mainly by the aluminum layer to bear the stress load.
The aluminum layer of POLYGON's PEX aluminum pipe is thicker, the long-term use temperature can reach
95℃, and the working pressure is 1.25MPa.

Easy operation：Slip-tight connections are quick and convenient, saving
time and effort.
Strong sealing：No need for O-rings and sealing materials, adaptable to a
variety of harsh working environments.
Super adaptation：It has a full series of pipe fittings, and can apply PE-X,
Pe-rt, Pb and other pipes to meet various installation needs.
High-quality material：Selection of European standard brass CW617N hot
forging and precision machining manufacturing, and annealing process,
effectively eliminating internal stress in the metal organisation, to enhance
the strength of the fittings, to prevent cracking.
Product characteristics
Selected European standard brass CW617N after hot forging precision manufacturing, and annealing process, effectively
eliminate the internal stress of metal structure and enhance the strength of pipe fittings, which ensures no cracking.
Tensile strength ≥280N/mm², elongation ≥10%. It is suitable for the connection of S3.2 series PEX butt welding aluminum-plastic composite pipe of dn16*2.2, dn20*2.8, dn25*3.5 specifications. The product specifications are complete and
can fully meet the actual installation requirements. The pipe fittings are treated with bright nickel plating, which makes
them luminous and long-lasting without discoloration. After installation, the pipeline is horizontal and vertical, beautiful
and natural, and can be matched with the installation of the open mounting buckle groove.
Sliding sleeve connection is produced in order to make the pipeline in the radiator heating system more
compact and more reliable connection, with simple operation and strong connection.

Clamping type fitting
Features and advantages of products
The clamping type fitting is to insert the pipe into the fitting, and use a
special clamping tool to fix the pipe into the fitting. As a more advanced
connector, it is widely used in water system, heating system, gas systems
and other piping systems. In the application of aluminum-plastic pipe connection, it can play its high pressure resistance, prevent leakage, tight and other
characteristics.
Stable performance: can withstand low and high temperature
Double seal design: avoid leakage hazards, long overall service life
Smooth surface: bright nickel plating treatment, lasting without discoloration
Easy installation: beautiful pipe installation
Prevent cracking: high strength, good toughness, ensure no cracking
Anticorrosive and durable: external steel sleeve thickness 0.7mm, more
safe and reliable; After special treatment, excellent corrosion resistance

Diversity water collector refers to the distribution of water supply and return, flow regulation and control, gas collection can be
manually or automatically excluded. The water separator consists of a water distribution main and a water collection main. The
water distribution main is connected to the water supply pipe of the pipe network system. Its main function is to distribute the
hot water from the pipe network system to the rooms that need heating indoors through the heating pipe buried under the floor.
When hot water flows in the floor heating pipe, it transfers heat to the floor, and then radiates heat to the room through the floor.

Integrated forging： One piece forging avoids leakage and improves reliability greatly.
Anti-corrosion and durability：The surface is treated with three protective processes, including
surface densification enhancement treatment, anticorrosion treatment, and surface spraying
treatment, which fundamentally solves the discoloration problem of ordinary copper surface, with
longer life and more stable performance.
Large flow：32.5mm main body diameter and 13.5mm branch inner diameter provide stable and
sufficient flow guarantee.
Large wall thickness：The average wall thickness is 2.3mm with better pressure performance.
Intelligent I-type Manifold and Collector
High-quality material：High-quality brass 59-1, one piece forging.
Sealed joint：The joint adopts double O-ring seal, which is safe and reliable.
Surface treatment：Sand-blasted surface and pickling treatment make the surface high-end
and easy to be cleaned.
