  • PVC-U Pipes
    UPVC (unplasticized polyvinyl chloride) plastic pipes and fittings are commonly used in plumbing and irrigation systems. UPVC pipes are lightweight, strong, and corrosion-resistant, and can be used for both above-ground and underground applications. They are also resistant to chemicals, making them suitable for a wide range of applications.   UPVC pipes come in different sizes and thicknesses and can be used for a variety of different applications, including water supply, irrigation, drainage, and sewage. They are also used in industrial settings for the transportation of gases, liquids, and chemicals.  UPVC pipes and fittings are resistant to corrosion, high impact strength and low fluid resistance (flow rate is 30% higher than that of the same size steel pipe). The price and maintenance cost of UPVC pipe are cheaper than the same size steel pipe.  UPVC pipes and valves are often preferred over other materials due to their durability, low cost, and ease of installation. They are also an eco-friendly and sustainable option for many applications.
