The Chlorine Institute Recovery Vessel is an effective and straightforward means to contain most leaks that may occur in a chlorine cylinder.
The recovery vessel, however, also requires additional maintenance and care not required of the Chlorine Institute Emergency KIT-A.
The recovery vessels are an ASME stamped pressure vessels that have an ASME U-1A data report of manufacture, Any welded repair must be made by a certified shop holding an “R Stamp”. The manufacturer is a qualified facility that can provide an estimate for any potential repairs and testing.
The recovery vessel also requires hydro-testing every five years at a minimum test pressure of at least 11⁄2 times MAWP maintained for at least 30 seconds and visually inspected per CGA Pamphlet C-6 . The successful test date must be stamped on the vessel per CFR Title 49 173.3 ii. Note: Stamping cannot be on the sidewall of the vessel. The recovery vessel from Indian Springs has a raised nameplate with additional room for correctly stamping test dates. Vessels that do not pass hydro-testing must be taken out of service. Hydro testing can often be done by the manufacturer, local pressure vessel companies and cylinder re-qualifiers; however, you can also check with your chlorine supplier for additional resources.
The O-ring, like the emergency kit gaskets, must be replaced after every use and have a four year recommended shelf-life. Extra o-rings should also be on hand for emergency use. Care should always be taken to prevent any potential damage to the the vessel head and especially the o-ring grove. Damage to the vessel sealing area may be irreparable and require removing the vessel from service.
With proper care and maintenance, the Chlorine Institute Recovery Vessel should provide many years of dependable service.
