Plastic Industry in India. In the Indian context, the Plastic water pipes industry started stabling their foothold in the late 1960s. HDPE, PVC were the early entrants. In 1980, rapid capacity expansion on account of World Bank-funded water schemes further triggered the growth and acceptance all over the country. The hot water in HVAC (Heating, Ventilation and Cooling) systems are transported through pipes made of CPVC, a variant of PVC. Cold water in HVAC systems is channeled through PVC pipes. PVC water supply pipes are also used for agricultural irrigation. It generally saves 30-50% water compared to open channel systems. PVC, a combination of plastic and vinyl, is a durable material that can be manufactured at a low cost. Therefore, PVC piping offers homeowners great value! It can be used for water supply lines, with the NSF/ANSI-61 label meaning it’s safe to carry and transport potable water, as well as drainage systems. "Recycling PVC was a natural for us," he said. "We're known for our iron piping, which is made from 96% post consumer material." The core of each section of RePVC is made with the recycled plastic, accounting for 30% to 80% of the overall material in the pipe. It's approved for manufactured to ASTM D 4396, ASTM F 1760 and is NSF listed. Milestones in PVC Water Pipe History Technology and performance have made PVC pipe the most popular choice for water and sewer lines. 1932 – First tubes were made from polyvinyl chloride (PVC Welded Pipes are manufactured from Plate or continuous Coil or strips. To manufacture a welded pipe, the first plate or coil is rolled in the circular section with the help of a plate bending machine or a roller in the case of a continuous process. Once the circular section is rolled from the plate, the pipe can be welded with or without filler PVC pipes are manufactured by extrusion of raw material PVC, and generally, follow the same steps of typical pipe extrusion operations: Feeding of raw material powder into the PVC twin screw We Fabricate and Source USA made PVC Schedule Pipe that is not only dual marked but can be used in both DWV and pressure pipe applications. It is easy very to install and has much better sound deadening qualities than Foam Core Pipe. Pipe made of PVC is highly durable and has high tensile and impact strength. Manufacturing. As small as 16mm and as large as 630mm tubing/ pipes are manufactured using a machine called an extruder. PVC plastic is routed through a double screw stem extruder (conical twin screw) or a parallel double screw extruder. Molding determines the wall thickness of the PVC hose. The diameter of the pipe is made by the PVC pipe MTs6v.
