uPVC pipes for plumbing are made of unplasticized polyvinyl chloride and are highly durable, lightweight, and resistant to corrosion and chemicals. These pipes have a smooth surface that reduces the accumulation of deposits and makes them easy to clean. uPVC pipes also have excellent insulation properties, which helps prevent heat loss in hot water systems. They are widely used for water supply, drainage, and sewage systems due to their low maintenance requirements, long service life, and affordability.
