SFD is a laser sublimated rupture disc available in sizes up to 24”. Due to its vacuum resistance and the wide range of response pressures from 2 to 431 barg, SFD is ideal for a variety of gas or liquid applications, in the oil and gas industry, petrochemicals and chemicals as well as many others.
The standard operating ratio is up to 80 %* of the minimum response pressure.
The advanced laser manufacturing process guarantees fragmentation free opening even at the highest pressures. Sublimated on the vent side, the SFD offers a smooth process face which reduces the risk of corrosion.
