Specification of Rupture Disk Burst Pressure

A recent incident involving a rupture disk pointed out some of these problems. A vessel was rated at 150 pounds per square inch (psi) at 400° F, and a rupture disk was specified with a set pressure of 150 psi at 400° F. The process fluid was mostly steam, and at 150 psi, the saturation temperature of …

May 31, 2018·If you take a valve from a cylinder rated at 3000 psi, it should have a burst disc rated around 5000 psi (5/3 or 1.66 times the working pressure). Now, take that same valve, without replacing the the burst disc, and place it in a cylinder rated for 2400 psi. You now have a burst disc rated for 5000 psi when it should have rating of 4000 psi.

The oxygen storage cylinder has a capacity of 38 cubic feet and is stored at 1800 psi. An oxygen rupture disc will relieve oxygen pressure if the oxygen cylinder pressure reaches 2700 to 3000 psi. A green overboard indicator on the outside surface of the dorsal fin will be ruptured or missing to indicate that the rupture disc is not intact.

CHAPTER4 REVIEW AND ANALYSIS OF APOLLO 13 ACCIDENT

The burst pressure of the oxygen tank is about 2200 psi at -150° F, over twice the normal operating pressure at that temperature. The relief valve is designed to relieve pressure in the oxygen tank overboard at a pressure of approximately 1000 psi. The oxygen tank dome is open to the

STANDARD OPERATING PROCEDURE Compressed Gas …

An unsecured cylinder may tip and become damaged in a manner that the release of internal pressure can cause the cylinder to become a dangerous high-speed projectile. A fire threatening the cylinder can cause a rupture or explosion. A flammable gas leak can cause a buildup of explosive gases.

Compressed Gas Cylinder – Health Safety & Environment

This danger has happened when unsecured, uncapped cylinders were knocked over causing the cylinder valve to break and high pressure gas to escape rapidly. Most cylinder valves are designed to break at a point with an opening of about 0.75 cm (0.3 inches). This design limits the rate of gas release and reduces cylinder velocity.
