4 Hose, Quick-Connects, and Sample Cylinders Overpressure Protection Compressed gas cylinders must be equipped with pressure relief devices in accordance with United States DOT regulations and CGA S-1.1. The CGA standard lists devices that can be used with speci˜c gases. It also contains information on other types of pressure relief devices. ˜ Be sure to use the correct pressure-relief device for the gas being used. ˜Proper ˜lling of the cylinder according to DOT speci˜cations, or other local regulations, is critical in preventing overpressurization. Rupture Disc Units Swagelok rupture disc units pro tect sample cylinders from overpressurization by venting the cylinder contents to atmosphere. The rupture disc is welded to a body that is threaded into a valve body or a rupture disc tee and sealed by an elastomer O-ring. The rupture disc can be easily replaced without removing the valve or the tee from the cylinder. Nonrotating-Stem Needle Valves with Rupture Disc Units Rupture Disc Tees These compact assemblies are designed for use with various Swagelok valves. Tees are made of 316 stainless steel. Each tee includes a rupture disc unit. CDBARupture Disc Precautions 1. Do not use rupture disc devices in a location where the release of the cylinder contents might create a hazard. The rupture disc vents to the atmosphere through six radial holes in the body. Pressure is released suddenly with a loud noise, and gases escape at high velocity. 2. Know the burst pressure. (This rating is marked on the end face of the rupture disc unit, as required by CGA S-1.1.) 3. Be sure the maximum burst pressure does not exceed the cylinder test pressure. 4. Be sure the minimum burst pressure is at least 40 % higher than the cylinder ˜lling pressure. 5. Inspect rupture discs regularly. The strength of rupture discs deteriorates with time due to temperature, corrosion, and fatigue. Pulsating pressure, vacuum/ pressure cycling, heat, and corrosive ˚uids and atmospheres can reduce the disc™s burst pressure. 6. Do not use rupture discs to protect vessels with volumes greater than 3 gal (11 355 cm 3) for compressed gases or 1 1/2 gal (5677 cm 3) for lique˜ed gases. 7. Provide suitable means to isolate the sample cylinder from the system in case the rupture disc bursts while taking a sample. 8. In cylinders with lique˜ed gases, a small temperature increase during transportation or storage will cause the liquid to expand and may cause the rupture disc to release its contents. See local regulations and other appropriate guidelines for safe ˜lling limits for your application. Ordering Information and Dimensions Dimensions are for reference only and are subject to change.

6 Hose, Quick-Connects, and Sample Cylinders Features Made from 316 stainless steel or alloy 400 tubing Offered in 1/4 or 1/2 in. NPT sizes Marked fiOutage Tubefl for identification Construction Outage tubes are welded to the male inlet end of an adapter or tee. This adapter or tee is then threaded into the female port of a sample cylinder. Outage tubes can also be welded directly to the male inlet of a Swagelok nonrotating stem needle valve. The valve is then threaded into the female port of a sample cylinder. Purpose Outage tubes provide a vapor space of the desired volume in cylinders containing lique˜ed gases, so that liquid in the cylinder can expand if the temperature increases. Without enough vapor space, a small temperature increase can cause the liquid to expand and increase the pressure dramatically. See local regulations and other appropriate guidelines for safe ˜lling limits for your application. Use Outage is the vapor space in the cylinder expressed as a percentage of the total volume of the cylinder. % outage = (vapor space/total volume) ˚ 100 The cylinder is held vertically with the outage tube at the top, as shown. The length of the outage tube determines the amount of vapor space. Sampling methods and the use of the outage tube are described in technical publications such as ASTM D1265, Standard Practice for Sampling Lique˜ed Petroleum (LP) Gases (Manual Method). Tube Length Outage tube length (L) is measured from the end of the pipe ˜tting to the end of the tube. Standard tube length is 10.4 in. (26.4 cm). Tubing can be cut to a desired length; instructions are included. Outage tube adapter Outage tube welded to male NPT end Liquid Outage tube Vapor space Total volume LOutage Tubes
