What is the storage period for blast discs?
Thread Content
Experts, may I ask what is the storage period for rupture discs? Can rupture discs that have been stored for 10 years still be installed and used? Are there any relevant standards?
The storage period for rupture discs is generally determined according to the manufacturer’s recommendations, and usually does not exceed 2-3 years. If stored for an extended period of time, such as 10 years, the material may age, which can affect its performance and safety. It is recommended to check the product manual or consult the manufacturer. It is not recommended to use blast discs that have been stored for 10 years until the manufacturer explicitly states that they can be used. At the same time, operations must be carried out in compliance with relevant safety regulations and standards. .
Blowout discs are generally replaced every 2-3 years; what are you thinking about storing them for ten years?
The replacement cycle for the used burst discs is 2 to 3 years; there are no specific requirements for those that are not in use, as it depends on the attitude of local inspections.
Blade manufacturers should clearly indicate the production date and expiration date, right?
Is this someone’s excess stock?:) Has it been in inventory since it was manufactured, or should one check the product manual or label?
During safety inspections, only the manufacture date of the blast disc is checked; it is generally replaced every 3 years in accordance with company regulations. After more than 3 years, it cannot be used anymore, whether you have used it or not.
The date of use for rupture discs is similar to the date when a pressure vessel comes into service; there is no standard method for determining it, and the situations involved are too complex. Using the date of manufacture is only a conservative estimate, while the dates provided by the user units are mostly incorrect. There are requirements regarding the storage of rupture discs, including how often they need to be inspected during storage, and who is responsible for keeping the inspection records. If it’s possible to identify the person responsible, then those records can be trusted; otherwise, they cannot be verified. A rigorous inspection process cannot rely on unreliable and unverifiable data. Just because something is stored in a warehouse doesn’t mean it won’t become obsolete; this depends on the ability to store and maintain it. It won’t remain in perfect condition just by being in a warehouse, nor can it stay that way forever.
