Ductile iron flange manufacturers

Ductile iron uni flange manufacturer in India, ductile iron blind flange exporter in India

Ductile iron companion flange suppliers, ductile iron backup flange stockholder in India, ductile iron zip flange stockist, dealers of ductile iron reducing flange in Mumbai, ductile iron quick flange distributor

Ductile Iron is also known as nodular cast iron, spheroidal graphite cast iron and ductile cast iron and this is for the simple reason that ductile iron is essentially a kind of cast iron. Ductile Iron Flange can be obtained online from the many suppliers and manufacturers who deal with this kind of product. ductile iron blind flange have a proven track record in the field, for above-ground applications, as well as under-ground applications. ductile iron companion flange are very easy to assemble and they are also corrosion resistant and that is why they are used in various application areas where ductile iron pipes are used.

The Chemical Composition of ductile iron uni flange is Iron – 94%, Carbon 3.2 – 3.60%, Silicon 2.2 – 2.8%, Manganese 0.1 – 0.2%, Magnesium 0.03 – 0.04%, Phosphorus 0.005 – 0.04%, Sulfur 0.005 – 0.02% and Copper <= 0.40%. ductile iron zip flange & ductile iron reducing flange are in big demand today on a global scale, as they have very high tensile strength and also because they can be procured in many different dimensions. By using a ductile iron backup flange and a ductile iron quick flange, it thus becomes possible to very easily connect almost any kind of 125 lb. faced and drilled flange. Ductile iron flanged spool are available in various lengths, based on the need of the application in which they will be used. ductile iron pipe flange connections are covered by 3 applicable standards of ANSI1/AWWA2 and these are ANSI/AWWA C110/A21.10, ANSI/AWWA C115/A21.15 and ANSI/AWWA C153/A21.53. Ductile iron is used in many applications and these include crankshafts, housings and manifolds, machine tooling, suspension system parts, wheel hubs, truck axles, hydrostatic barrels, gears and gear boxes, etc.
