Description:Starwin composite pipes 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. 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 PERT-Al-PEX composite pipe PERT-Al-PE composite pipe Specifications: 16 x 2.0 20 x 2.0 25 x 2.5 26 x 3.0 32 x 3.0 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 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
