Rupture Disc is a pressure relief device that prevents system from over-pressurization. If a plant or a system consisting of vessels, containers and pipes is designed to have a weak spot, relatively weaker from other area,, and when the system or plant inner pressure reaches to certain point, the weak spot will burst (rupture) to release the pressure. This prevents system or plant from over-pressurizing and protects other areas of the system. Given conditions to this weak spot, including shape, dimension, pressure, temperature, and being replaceable, it is called Rupture Discs or Bursting Discs (hereinafter called RD).

RD units offer proven protection to equipment and piping in various applications including chemical and nuclear industries. RD units protects such equipments from risk of bursting caused by abnormal pressure rising from mis-operation, excursion or flare. The RD design seals 100% at all pressure ranges. This eliminates the problem found in most safety devices of seal leakage during normal operation and eliminates the leakage of expensive, combustible, poisonous, and radioactive fluid.

RD units have features as shown right and normally utilized as safety devices.

Not only releasing excess pressure, RD unit functions as quick-opening valves with a certain conditions such as temperature, pressure, and timing. RD units are also utilized in pilot plants and equipments applications.

We believe RD has an absolute advantage as a safety device and we have continued research and development of RD and provided products with high credibility to our customers. Along with our improved engineering skills developed with proven production record, and by improving and expanding our manufacturing facilities, we will continue to improve our product reliability. By this approach, we assure we will fulfill your expectations.
