GSW Pipes and Fittings
Overview
Material Combinations/ Technical Details
GSW (Glaze Stone Ware) Pipes and Fittings are high-performance ceramic drainage solutions designed for underground sewer and wastewater systems. These pipes feature a smooth glazed interior that ensures excellent flow efficiency and prevents buildup, while their hard, vitrified exterior provides outstanding resistance to corrosion, chemicals and abrasion. GSW pipes are eco-friendly, non-toxic and offer a very long service life, making them ideal for permanent drainage infrastructure.

Product Catalog
The GSW (Glazed Stoneware) Pipes shown are high-density vitrified clay conduits, salt-glazed at temperatures exceeding 1100°C to create a chemically inert, non-porous interior. Technically, they feature a robust socket and spigot (S&S) joint complying with IS 651:2007 standards , ensuring high crushing strength for deep-earth burial without deformation. These pipes are primarily utilized in municipal sewerage networks, industrial effluent disposal, and household drainage systems due to their 100-year service life and immunity to corrosion . They are available in standard internal diameters of 100mm, 150mm, 200mm, 230mm, 300mm, and 450mm.
This is a Salt-Glazed Stoneware Pipe, a heavy-duty ceramic conduit manufactured from vitrified clay and fired at 1100°C to achieve a non-porous, acid-resistant finish. Technically, it features a socket and spigot joint (S&S) with grooved ends for secure cement or rubber sealing and complies with IS 651 standards for high crushing strength. These pipes are primarily used in underground sewerage, municipal drainage, and industrial chemical waste disposal due to their 100-year service life and immunity to corrosion. It is available in standard internal diameters of 100mm, 150mm, 200mm, 230mm, and 300mm.
