UNITECH CPVC Pipes are made of Chlorinated Polyvinyl Chloride as per the latest industrial norms set by the Bureau of Indian Standards. The reason CPVC pipes are preferred over conventional PVC as the former is much more flexible and can withstand much higher temperatures.
The biggest advantage is they are quick to install with no issue of corrosion, leakage, scaling, or pitting. UNITECH CPVC Pipes are ideal for water supply of both hot and cold water. With the latest technology and greats efforts put in innovation and design, we at UNITECH PVC Pipes have manufactured CPVC Pipes that are unaffected by aggressive harsh water and doesn’t allow any mineral deposits on the inner surface of the pipe. We assure that our esteemed clients will get the best quality product with us.
