About starwin composite pipe:

 

Starwin composite pipes have different types and diverse specifications, with high quality and cost-effective price, which lead us to be recognized as a credible enterprise by the national and international clients.

 

All the raw materials are imported from international famous enterprises, so our products have no contamination whatever in manufacturing process or for the usage. Quality control tests are carried out in all stages of the production process, from the raw materials and the fittings, through the production to the final tests of the finished products before the packing and delivery.

Characteristic:

 

Thermal conductivity:

0.45W/(m.k), 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.

 

Characteristics:

At normal temperature, it does not dissolve in any known solutions and is resistant

against various kinds of acid, alkali and salt.

 

Sanitation:

Starwin 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,

Starwin 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 Starwin pipe can have a working life of 50 years.

 

Burning resistance:

The PE(X)-Al-PE(X) composite structure acquires Starwin pipe a much better burning

resistance than that of all polyethylene pipe.

 

Hydraulic functions:

The roughness coefficient of Starwin pipe is 0.007mm. The inside wall is very smooth,

scale free and low flow resistant, which makes Starwin pipe ideal for fluid

(such as water) carrying. Due to the 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.

 

Other advantages:

The core layer of aluminum guarantees static resistance, lightness and oxygen tightness; it also ensures no growth of microorganism inside water pipe and the safety in gas supply.

 

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.

 

Starwin Multilayer 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.
