UNIPLASTUnplasticized Polyvinyl Chloride Pipes (UPVC)

uPVC Pipes are light in weight, flexible and durable. PVC is most popular material due to its superior strength and stiffness to weight ratio, thus enabling more cos effective pipes to be produced. UNIPLAST uPVC pipes are manufactured with accordance to the international standards for different types of uses mainly to British & European standards. Our manufacturing standards are BS6099/1928, BS4607, BSEN 1401, DIN 19531, DIN 19534, DIN 8062/63, BS5255 and BS 4514.

Advantages of UNIPLAST UPVC Pipes System.

Light Weight: Hence transport and handling is simple and convenient.

Chemical Resistance: A Excellent chemical resistance of UPVC to acides, alkalies and oxidizing and reducing agents makes it suitable for all applications.

High Flow Rate: A The smooth internal bore gives excellent flow properties which remain constant throughout the life of the systems.

Non-inflammable: UPVC does not support combustion and is self-extinguishing.

Non-Conductive: A UPVC is a non-conductor and hence not attacked by galvanic or electrolytic action.

Weather Resistance: A Specially blended UV stabilized compound offers an excellent outdoor weathering performance. High durability.

Easy Installation: A Tough, impact-resistant and easy to install.

Corrosion Resistance: A UPVC is non-corrosive and hence constant with water does not deteriorate the material.

Aesthetic Superiority: A UPVC is aesthetically far superior to conventional systems.
