CSA B620:20 Periodic Inspection: TC 341 External Inspection, Leakage Testing, and the Vacuum Alternative

CSA B620:20 sets how a highway tank used to transport dangerous goods in Canada is designed, manufactured, marked, tested, inspected, and maintained, and its Clause 7 carries the periodic inspection and test regime that keeps a tank in service. This instructor-led course puts an inspector in front of a TC 341, the Canadian specification for highway tanks carrying nonflammable refrigerated liquefied gases, and works the activities that decide whether that tank stays in service: the external inspection, the leakage test that Clause 7.1.2 brings to this specification by event rather than by calendar, the report and marking requirements in Clause 7.3 and Clause 7.4, and the Annex C vacuum alternative an owner may adopt in place of the Table 7.2 internal inspection and retest. You will learn what a TC 341 actually is, what its metal identification plate tells you, what a double wall and a vacuum annulus add to the job, what Clause 8.1.6 asks of the person doing the work, and how the Canadian regime lines up against the 49 CFR Part 180 work a United States Registered Inspector already does.
