PIPES
			PE Composite Pipe
FITTINGS
ElectrofusionComposite Fitting

The rubber ring and electrofusion dual-sealing polyethylene composite pipe is made of high-density polyethylene and reinforced materials. The high-strength reinforced material has high tensile strength,can bear 60%-70% of the internal pressure of the pipe, while retaining the flexibility of the polyethylene material.

According to the pressure rate, the diameter, quantity and number of reinforcement layers of the reinforced material are adjusted accordingly, pipe wall thickness have small change, to ensure bearing enough pressure and reduce the influence on the flow rate of the water. Each pipe has a rubber ring and electrofusion dual-sealing socket at one end, during construction process,the pipe can connect the fittings by socket-spigot joint directly, no need additional  pipe fittings.The combination of the two sealing processes of rubber ring seal and electrofusion seal,makes full use of the superior sealing performance of the rubber ring and the electric fusion fusion process, and has strong environmental adaptability after electric fusion.

Production Standard: T/CECS 10210-2022 (Chinese Association Standards)
Diameter range: DN50-DN800

GOOD RESISTANCE TO RAPID CRACK GROWTH

The rapid cracking of the pipeline may instantly cause a major accident of damage to the pipeline of more than ten meters or even thousands of meters. Polyethylene has excellent resistance to rapid crack growth. At the same time, it also has good resistance to scratches and slow crack growth. It is a kind of Safe Plumbing Products.

DURABLE and ANTI-CORROSION

Polyethylene is an inert material, except for a few strong oxidants, it can resist various chemical media and microbial erosion, no electrochemical corrosion, no need for anti-corrosion coating, and the designed service life is 50 years

SOFT and BENDABLE

Good flexibility enables small-diameter polypipes to be coiled without pipe connections, reducing material costs, and is used for non-excavation construction. The direction of the pipeline can be changed according to the requirements of the construction method.

EASY MOVE and INSTALL

Low density (about 0.94-0.965g/cm3), light weight, easier to transport and install than unimpeded steel pipes or cast iron pipes, reducing construction labor intensity and engineering installation costs.

HIGH TOUGHNESS

The elongation at break generally exceeds 500%. It has strong applicability to uneven settlement when shutting down, and has excellent seismic performance. It can be applied to harsh construction conditions such as uneven foundation and dislocation.

SANITATION and ENVIRONMENTAL PROTECTION,HIGH CONVEYING EFFICIENCY

Hygiene and environmental protection, compound domestic drinking water transmission and distribution equipment requirements. The inner and outer surfaces of polyethylene pipes have high smoothness, high transmission efficiency, and can maintain excellent hydraulic performance during the service life.

RELIABLE CONNECTION

Hot-melt, electro-fusion connection ensures the identity of the interface material, structure and the pipe body itself, and the tensile strength and burst strength of the interface are higher than the pipe body. The co-extrude interface is clear, long-term sunshine is not easy to fade, and the depth of embedding in the pipe wall thickness is small, so as to avoid welding defects.

 

1: Higher strength resistance and creep resistance. 
2: Excellent stiffness, impact resistance. Low linear expansion coefficient. 
3: Smooth inner wall, won't covered with dirt. Low flow resistance, high flow capacity. 
4: Both the inner and outer wall are made of plastic, lead the pipe and fittings owns good corrosion resistance. 
5: Light weight, easy to transport. 
6: Use electro-fusion joint, no leakage in the joint, fast and easy installation. 
7: The product is composited with steel wire and plastic, overcome the fast stress crack of plastic pipe. 
8: Good abrasion resistance. The product can work for more than 50 years under normal use.
