Detailed Product Description

Starwin composite pipe is composite pipe of five layers, inside and outside layers of which 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 way. High quality and cost-effective price lead us be recognized as the credible enterprise by the national and international clients.

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.^oC,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. 

Thermal conductivity:

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

of insulating materials

Corrosion resistance:

The inside and outside polyethylene are a kind of symmetrical and non-polar material

with stable characteristic. At normal temperature, it does not dissolve in any known solutions and is resistant against various kinds of acid, alkali and salt.

Hygiene:

The pipe is hygienic, nontoxic, rust-free and no growth of microorganism, thus avoiding contamination to water.

Weathering quality and working life:

It can be concluded that if utilized under the stipulated conditions and pressures,

The pipe can have a working life of more than 50 years. The compelling weathering

test by the Compound Material Research Institute of National Chemical Ministry

also proves that The pipe can have a working life of 50 years.

Burning resistance:

The composite structure acquires The pipe a much better burning resistance than that of all polyethylene pipe.

Hydraulic functions:

The roughness coefficient of The pipe is 0.007mm. The inside wall is very smooth,scale free and low flow resistant, which makes The pipe ideal for fluid (such as water) carrying. Due to her hard but flexible composite structure, the lashing pressure is quickly eliminated, thus no disturbing sound occurs.

Installation:

Bendable but never spring back, decreases lots of fittings attached, easy installation,

spares lots of installation time.

Applications:

Because of its excellent performance, it can be widely used in construction, medical, food, Chemicals, cold and hot water supply system ,and air-condition system and many other industries. Because of the
