C O2 CYLINDERS AND SAFETY DISC - 10330_47

Carbon dioxide cylinders should be charged with "bone-dry" carbon dioxide. Extreme care must be taken in the charging, weighing, sealing, and testing of cylinders. The safety discs of the cylinders are painted various colors to identify the pressure at which they will rupture. The correct color disc must be used in every case.

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.

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 steam is about 366° F.

Compressed Gas Cylinder – Health Safety & Environment

Most cylinders have one or more safety-relief devices. These devices can prevent rupture of the cylinder if internal pressure builds up to levels exceeding design limits. Pressure can become dangerously high if a cylinder is exposed to fire or heat, including high storage temperatures. There are three types of safety-relief devices.

Rupture disc - Wikipedia

I am curious what the maximum working pressure of a oxygen cylinder would be? Searching the internet I am not coming up with much information. Looking at the tanks here, the regulator reads up to 4000 PSI. The rupture disk on the valve has "3775" stamped on it which I am assuming is 3775 PSI. That is on a "300" size tank.
