    Standard

    The company has the foreign trade proprietary import and export right, the product sells the domestic, the foreign market, has higher awareness and Reputation, the credibility of the enterprise.

    Lightness
     UPNC is approximately half weight of Copper pipe, one-fifth   weight of Steel pipe and one-tenth weight of Cast lion pipe. Transport and   handling therefore are both simple and convenient. Chemical Resistance
     The   excellent chemical resistance of UPVC to acids, alkalis, oxidizing and reducing   agents makes it particularly suitable for a wide range of industrial   applications. High Flow Rate
     The internal surface of UPVC pipe and   fittings“extremely smooth”equivalent to a Manning and Cutter coefficient of   0.010,giving excellent flow propertie4s which remain constant due to reduced   build-up of scale.
     Non Conductivity
     UPVC is a non-conductor of   electricity, and is therefore not subject to galvanic or electrolytic action.
     Weather Resistance
     The UPVC pipes and fittings range is manufactured   from a specially formulated UPVC compound, developed from many years for trial,   resulting in a tough resilient materials with excellent outdoor weathering   performance.
     Low Installation Cost
     Tight dependable connections are made   by solvent welding of UPVC pipes and fitting. This combined with the other   advantages of lightness, flexibility and the use of prefabrication techniques,   can afford savings both in time and money.
     Effect of Elevated Temperature
     The UPVC remains stable under load to a temperature of approximately 75°c   and is therefore satisfactory for use in soil or waste systems. Specialized   Applications
     The systems are more than adequate for normal domestic   applications in low and multi-rise dwellings. There more Specialized   Applications, such as tea-makers, autoclaves, hospital, industrial kitchens and   laboratories are concerned, where prolonged discharges of liquids at elevated   temperatures can occur.
     Laying Instruction &Jointing Procedure
     Clean   the outside of the pipe’s spigot end and the inside of the sealing groove of the   fitting. Apply the lubricant supplied by us uniformly to the spigot end, sealing   ring and pass the spigot end into the socket containing sealing ring until fully   home. Mark the position of the socket edge with the pencil or felt-tip pen on   the pipe, then withdraws the pipe from the socket by approx.10mm (toward thermal   expansion gap).
     Spacing of Pipe Clips
     With horizontal runs, the pipe   clips should be spaced at intervals of no more than ten times the pipe. Vertical   lines are spaced at intervals of one meter to maximum of two meters according to   pipe diameter.
     Advantages of CPVC Pipes and Fittings
     This is   thermoplastic piping material which can be used for higher temperature   application. it is a special Polymer with higher class transition point, which   means advantages over regular
     UPVC Pipes and Fittings. CPVC remain its   mechanical strength at higher temperatures.
     CPC=93°C Max. UPVC=59°C Max
     Health Concern
     CPVC supports lowest bacteria growth compared with other   traditional piping materials.
     Scale Build-up
     CPVC supports no corrosion   and hence Scale build-up is inhibited.
     U.V. Exposure
     Since degradation   process in CPVC is Dehydrocholrination and not oxidation. The out door exposure   of CPVC pipe and fittings to U.V. do not break polymer;Hence, it is not only   being limited to a surface discoloration.
     Fire Safety
     CPVC does not   support combustion. No flame dripping, low flame spread and low smoke   generation.
     Water Hammer
     CPVC is much quieter than metal systems with   much less water hammer.
     Effect of Chlorine
     CPVC is unaffected by the   presence of chlorine in potable water supply unlike polyolefin which is affected   by chlorine and hence break down of its polymer followed by potential leaks.
     Low Thermal Expansion
     CPVC has a low coefficient of thermal expansion   hence reduces the amount of expanding when hot water is flowing, causing   reduction in “l(fā)ooking of pipe”.
     Easy, Cost Effective Installation
     Easy   to join by Solvent Cement, no need to use special tools. Installation is easy in   tight, confined or inaccessible places. No. need for alternative material such   as expensive brass fittings.
     Low Thermal Conductivity
     The low thermal   Conductivity of CPVC reduces heat loss through the wall.
