CPVC Pipe Dealers in Bowbazar, Kolkata

Pipes are manufactured in Copper Tube size [CTS] from ½ “to 2” with two different standard dimensional ratios SDR-11 and SDR-13.5 are made from CPVC compound. Pipe & fittings are produced as per SDR-11 meet the requirement of ASTM D 2846 where as the pipes with SDR-13.5 meet the requirement derived from ASTM F 442, specific to CPVC in Iron Pipe Size (IPS) dimension, which can also be applied to CPVC pipes in CTS dimension. Apart from having the same physical properties, SDR-11 and SDR-13.5 have different wall thickness and therefore, at any given temperature, have different pressure rating.

CPVC or Chlorinated Poly Vinyl Chloride is produced by chlorination of poly vinyl chloride (PVC) resin. In the process, the chlorine gas is decomposed into free chlorinewhich is then reacted with PVC in a post production step, essentially replacing a portion of the hydrogen in PVC with chlorine. The extra chlorine molecule helps to increase its glass transition temperature (Tg) significantly, resulting in a CPVC which is extremely heat resistant. As a result CPVC performs much better in high temperature and high pressure applications than PVC. Some of the advantages of CPVC for piping systems are: Very good chemical and corrosion resistance Outstanding chemical resistance No electrochemical corrosion Long service life, even under intensely corrosive conditions No support microbial growth Simple installation using solvent cementing Smooth inner surface Exceptional flammability resistance No influence on drinking water
