Detailed Product Description

Starwin composite pipe is composite pipe of five layers: inside and outside layers
are made of high-density polyethylene (HDPE), cross-linked (PEX), PPR or polyethylene
raised temperature (PE-RT), tightly bonded with melt adhesive to the mid-layer
of aluminum core which is longitudinally welded in an butt-welded or overlapping
welded way.

Advantages:

The pipes combine the advantages of plastic pipe and aluminum pipe. Features of composite pipe as follows:

1. Compared with the metal pipe, the composite pipe has the same strength, easy to bend,  

reluctant to retain former shape

2. Super properties of high temperature, high pressure and corrosion resistance

3. Smooth inner surface of the pipe reduces resistance to the fluids. The ability to conduct water is 30% more efficient

4. Good property of heat preservation, heat conduction coefficient is 0.45W/m.k,which is much less than metal pipes and it can save insulation materials outside the pipe

5. Easy to cut and install. It can be connected with special fittings instead of screw fittings; small diameter pipes can be rolled and packaged. Once received the pipes (bent radius >5d) can be cut to desired length and simply bent in order than many directional parts such as elbows or angles ate no longer recessing very convenient to install, much time and labor cost can be saved;

6. Lifespan of The composite pipe is more than fifty years. 

7.Excellent Thermal conductivity:

0.45W/m.k., about 1/100 that of steel pipe but only several times higher than that

of insulating materials

Application field:

Its excellent performance leads the widely use in construction, medical, food, Chemicals, cold and hot water supply system ,and air-condition system and especially underfloor heating system.
