Specification of 1 Inch ERW Black Iron Pipe
Iron pipe is a pipe or conduit used as a pressure pipe for the transmission of water, gas, or sewage or as a water drainage pipe. This pipe is often also called the black pipe.
Electric Resistance Welded (ERW) pipe is manufactured by cold forming flat steel strips into round tubes and passing them through a series of forming rollers to obtain longitudinal seams. The two edges are then simultaneously heated with a high-frequency current and squeezed together to form a bond. Longitudinal ERW sutures do not require filler metal.
Iron pipe proved to be a useful material for the manufacture of water pipes and was used as a replacement for the original elm pipe that was used previously. These water pipes consist of individual cast pipe sections, often called rods, joined together by various connection mechanisms. Flanged joints consist of a flat machined surface bolted together with gaskets between them to prevent leakage. This type of pipe connection is still used today, usually for above ground pipelines in water treatment plants and factories.
