For a variety of plumbing and drainage applications, hubless centrifugally cast (spun) iron pipes, fittings, and accessories provide an effective and dependable solution. Their spigot-end shape makes couplings and installation easier, and their resilience to corrosion, durability, and leakage add to their significance in contemporary drainage and plumbing applications. These elements are necessary for contemporary infrastructure and lifestyle because they ensure the effective and safe management of water in commercial, industrial, and residential contexts. They are essential to building projects, environmental preservation, and public health.
Under IS standard IS 15905:2011, all hubless centrifugally cast (spun) iron pipes, fittings, and accessories-spigot series are covered by the required ISI Certification Scheme.
According to this standard, sockets must be absent from cast iron pipes, fittings, and accessories, and they must have a hubless design (spigot type). Sand casting is often used in the production of the fittings and accessories described in this standard. It specifies 50, 75, 100, 150, and 200 mm as the nominal diameters (DN) for pipes and fittings. According to IS 210, the cast iron used to make pipes, fittings, and accessories must meet the FG 150 grade. In order to avoid problems like warping or shrinking faults, manufacturers must take all required care throughout the stripping process.
Without the ISI Mark, this product cannot be marketed, imported, or exported into the Indian consumer market.\
Indian Standards Institute, or ISI was renamed the Bureau of Indian Standards (BIS) in 1987. The official mark that the Bureau of Indian Standards provides for manufacturers of various goods is the ISI Mark. It is used to indicate compliance with Indian standards (IS) set by the Bureau of Indian Standards (BIS) and has been used as a conformity marking for industrial products. Manufacturers received permission from BIS to use the ISI Mark on items that comply with relevant Indian requirements through the product certification program.
Only manufacturers (domestic or foreign) who produce the finished product will be awarded ISI Certification. This will not be given to any product importers, traders, dealers, or distributors.
