Detailed Product Description

Starwin composite pipe have different types and diversiform 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.

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.

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.

Hygiene:
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:

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 underfoor heating system and many other industries.
