Steel pipes are long, hollow tubes that are used mainly to transport substance from one place to another. They are produced mainly by two distinct manufacturing methods which result in either a welded pipe or seamless pipe. This DPR describes the manufacturing process of a welded pipe. Basically, Mild Steel (MS) Pipes are manufactured with the usage of low carbon (less than 0.25%) steel sheets being the prime raw material. Due to the presence of low carbon content the pipes do not harden and are easy to mould and use. As they can easily be welded and formed in various shapes and sizes, it is largely used for pipelining and tubing purposes. Further they are also used for plumbing, fire fighting along with various other Industrial and Engineering applications. The pipes are generally coated with some metals/paints/varnish to prevent it from rusting but extra care should be taken in order to prevent the same under extreme conditions.
