Metal Udyog (India) is amongst the largest suppliers and stockists of Ductile Iron Fittings in India. In compliance with the European Standard EN 545:2010, Ductile Iron Fittings shall be cast in sand. The above-mentioned Standards define the dimensional criteria. The nominal thickness refers to the body’s main component. Depending on the form of the casting, the individual thickness at any given stage can be increased to satisfy localized elevated stresses (e.g. at an internal radius of bends, at the branch-body junction of tees, etc.)
The fittings shall be secured internally and externally, depending on the corrosive properties of the soils, with: the fittings mounted in non-corrosive soils shall be protected internally and externally with a fusion-bonded epoxy coating with a minimum dry film thickness of 250 microns in compliance with the European Standard EN 14901:2006 and with a thickness of 300 microns for corrosive soils.
The basic raw materials used in the process of manufacturing Ductile Iron Fittings are Pig Iron, Steel scrap, and ferroalloys. Quality assurance starts from the procurement of raw materials. An in-plant chemical laboratory is set up for the job.
The dimensions of the fittings are guided by national and international standards like ISO 2531, BSEN 545, IS 9523, etc. so as to ensure compatibility with pipes and other appurtenances. Push-fit socket and Spigot fittings, Flange fittings, and mechanically restrained joints are the various types of Ductile Iron fittings offered by Metal Udyog (India) in the market. In K12 pressure ratings, we sell these fittings that offer outstanding chemical and mechanical characteristics. Our Ductile Iron Fittings offered to have an outstanding elastic module, greater mechanical properties, and outstanding ductility that make these fittings durable for higher stress conditions. In any reducing and corrosive environment, our ductile iron fittings give excellent corrosion and oxidation resistance.
Our expert engineers ensure that our ductile iron fittings are dimensionally correct and follow both national and international quality requirements. After the production process, we ensure that each ductile iron fittings are passed through various destructive and non-destructive quality controls to measure various qualitative criteria of fittings and to have our esteemed best quality fittings supplied to the clients.
