Carbon Steel Threaded Flanges

Carbon Steel Threaded Flanges are basically used at the end of pipe or fittings with the concept of opening and closing the same for cleaning, inspection or some other purpose.

Carbon steel forged threaded flanges are meant for connecting pipes, valves, pumps and other equipment to form a piping system. Threaded Flanges do provides easy access for cleaning, inspection and modification.

These carbon steel forged flanges are available with us in many surface finish like varnished as what we can see in the above image. this carbon steel threaded flange is varnished. We can also manufacture and supply black finish, painted or galvanized or hot dip galvanized finish carbon steel forged threaded flanges in India.

Carbon steel Threaded Flanges are used for special circumstances with their main advantage being that they can be attached to the pipe without welding. Sometimes a seal weld is also used in conjunction with the Carbon steel threaded connection.

Carbon steel threaded flanges available in all most all sizes and pressure ratings, screwed (threaded) fittings today are used almost exclusively in smaller piping sizes.

A Carbon steel threaded flange is not suitable for a pipe system with thin wall thickness, because cutting thread on a pipe is not possible in such case. Thus, thicker wall thickness must be chosen according to the type of threads. ASME B31.3 Piping Guide indicates very clearly that where Carbon steel pipe is threaded and used for steam service above 250 psi or for water service above 100 psi with water temperatures above 220° F, the Carbon steel pipe shall be seamless and have a thickness at least equal to schedule 80 of ASME B36.10.
