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.
Starwin composite pipe can be classified as follows:
PEX-Al-PEX composite pipe
PEX-Al-PE composite pipe
PE-Al-PE composite pipe
PPR-Al-PE composite pipe
PPR-Al-PEX composite pipe
PPR-Al-PPR composite pipe (Stable PPR pipe)
PERT-Al-PEX composite pipe

(other specification can be changed according to customer's requirement)
Color:
White, Orange, Blue, Yellow can be changed according to customer's requirement
Manufacture Standards:
ISO 9001
UNE 53961-2002
ASTM F1335-2004
ASTM F1281
ASTM F1282
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.
