Carbon steel plate flanges is a form a rim at the end of a pipe when fastened to the pipe. It is used to seal the end of pipelines, valves or other connection. With high tensile strength it is available with a raised face and backups for easy installation. It is an iron-carbon alloy that consist up to 2.1 wt.% carbon. And carbon steels does not have minimum specified content of other alloying elements, however it often contain manganese.

Carbon steel slip on flanges is essentially a ring that is placed over the pipe end, with the flange face expanding from the end of the pipe by enough distance to apply a weld bead on the inside diameter.

It is useful for fluids at low pressure or with little risk of leakage. It is commonly used in , low-pressure compressed air lines, cooling water lines, firefighting water lines and process lines for substances such as steam, condensates, oil & gas, etc. It can be produced from recycled or virgin steel or a combination of both

Carbon steel forged flanges is used as a connection component for pipes, pumps and valves and other equipment to form a pipework system.It is usually welded onto pipes or screwed onto a threaded pipe end and then joined with bolts to make the connection.In order to make connection it is welded onto pipes or screwed onto a threaded pipe end and then joined with bolts.

Carbon steel blind flange does not have a bored centre or a hub. It has face thickness of a flange, a matching face type, and similar bolting pattern. It is used to seal a nozzle opening on a pressure vessel.
