How often are Dewar bottles inspected, and what are the inspection agencies?

Reply #22019-06-14

Welded insulated gas cylinders, commonly known as “Dewar tanks”. In accordance with Article 7.4.1.7 of the \"Regulations on Safety Technical Inspection of Gas Cylinders\" (TSG R0006-2014), welded insulated gas cylinders (including those used in vehicles) shall be inspected every 3 years. Any entity that has the qualification for regular inspection of welded insulated gas cylinders can carry out such inspections; this can be a private testing agency or a local special inspection institute.

That’s correct; currently, after 3 years, there are very few inspections or checks carried out. I work on welding insulated gas cylinders!

There are not many units qualified to inspect such bottles
