One of the main reasons why Cast Iron Fittings are considered for several industrial uses is because the metal offers many engineering properties. Hence these fittings are utilized in many ways such as for sanitary fittings, rail chairs, etc. Since the Ci Pipe Fittings exhibit good corrosion resistance properties, these fittings can be used in conjunction with pipes carrying water. With a melting point of about 1250C and a specific gravity value of 7.5, Cast Iron Flanges are used to connect pumps, valves, pipes as well as other equipment to form a system that does not require magnetic properties. While the metal has a tensile strength value of about 150 N/mm2, these fittings are good in compression as the Cast Iron Blind Flanges have a compressive strength of around 600 N/mm2. However, most manufacturers do not recommend using this metal for forging work due to its lack of plasticity.
The manufacturing process of Cast iron involves remelting of pig-iron with coke and limestone. Pig iron or as also referred to as impure iron is obtained from the iron ore.

Generally, Cast Iron Floor Flanges are used to connect either a threaded rigid conduit or an IMC conduit to flat surfaces. Therefore a floor flange proves to be very useful for hanging security cameras, smoke detectors or fire alarm signals/strobes as well as other low-voltage and electronic signalling devices from ceilings. Reckoned to be one of the oldest fittings, the Cast Iron Threaded Fittings aid in forging connections with pipes of smaller diameter, wherein the diameter measures between NPS 2 or smaller.
