PVC
are manufactured according to the highest quality standards in the industry
Technology and performance have made PVC pipes the most popular choice for water and sewer lines. It has been proven that plastic pipes are the ideal products for today's extensive continuum of commercial, residential and industrial sector application for with standing reisitance to wide range of chemicals, heat and pressure
Unplasticized polyvinyl chloride or uPVC is one of the most widely used thermoplastic materials, due to its flexibility of usage and competitive price. It is manufactured by the petrochemical industry which produce a from ethane and chloride and apply pyrolsis above 400oC to cause splitting into vinyl chloride and hydrochloric acid
The basic polymer is mixed with additives such as colour, filler, lubricants and stabilizers in accordance with a recipe determined by the properties of the finished product. The mix of compound is transported to either extruder or injection molding machines to be converted into the end product
uPVC pipes and fittings will not deteriorate under attack from bacteria or other micro organism and will not provide food source to micro/marco organisms and fungi. These pipes and fittings are also suitable for chemical industries as they have chemical resistance to most acids and alkalis. uPVC, being thermoplastic materials is prone to vaiance in physical properties based on vairation in temperature. It is important to take into account the application of end use and temperature conditions when selecting class and rating of Pipes (Wall thickness of Pipe)
