how to select best ms pipe

MS Pipe:-Low carbon steel (less than 0.25% carbon) is used to create mild steel (MS) pipes. The pipes are simple to use and do not harden because to the low carbon content. MS Pipes may readily be welded and moulded into a variety of forms and sizes for use in pipelining and tubing since they are made of mild steel. Plumbing, firefighting, and HVAC are some common applications for them, but they can also be utilized in a wide range of other industrial and engineering applications. Although these pipes are typically covered with other metals, paints, varnish, etc. to avoid rusting, extra care should be given in extreme circumstances.  These  pipes are  plain end and bevel end.
