C. I. Pipes & Fittings
Cast iron (CI) pipes were widely used for the transportation of water and sewage before plastic pipes were invented. They are one of the oldest piping systems present today and are now being replaced by high-density polyethylene (HDPE) pipes and polyvinyl chloride (PVC) pipes. Some cast-iron pipes are still in working condition, but most have deteriorated and are in need of replacement.
Cast iron pipes have a lifespan of 75 to 100 years, but evidence shows that some have lasted much longer. Cast iron pipes can handle low wastewater pressures even if the corrosion has occurred because of the thickness of its walls.
Though cast iron pipes corrode over time, the rust forms a layer over the remaining pipe that slows down corrosion. The benefits of cast iron pipes still make them a good choice for installing in homes, but with cheaper and less tedious options now available in the market, cast iron pipes are less preferred.
Plumbing is a system which includes supply of clean water at preferred locations in house or building. It takes away sewage or waste water hygienically. The Plumbing system is also divided into the water supply system and sewerage system. Both systems include series of pipes that convey both the water and waste water.
Among the plumbing pipes, cast iron pipes (CI Pipes) have been popular since the 19th century. They have a good compressive strength so that they can resist the earth pressure easily. They are extremely corrosion resistant and therefore, they are also used to transmit water. They are brittle and hence they are hard to cut and fit.
