Description:Starwin pipes combine the advantages of plastic pipe and aluminum pipe. Features of composite pipe as follows: 1. Compared with the metal pipe, Starwin 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, 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 Starwin composite pipe is more than fifty years Technical parameters: Heat conduction coefficient: 0.45W/m.k Expansion coefficient: 2.5 x 10-5m (m.k) Bend radius: ≥5° Wording temperature: -40 ~ +95°C Working pressure: 1.25MPa Oxygen diffusion: 0 Burst pressure: ≥5.5 ~ 8MPa Tensile resistance: ≥2,400 ~ 3,320N 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 characteristic. 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 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 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 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
