Ring Rolled Forging

At Seglian, we manufacturer v-band sealing joint rings, Marmon adaptor rings and other rolled flanges for oil, gas, chemical, and other industries.

Ring rolled forging is a process whereby a near net shape ring is produced as a one piece forging, which originates from a large diameter piece of bar stock.

Benefits of our ring rolled forging process
