Solution: Pressure vessel

Start of trial operation – When trial operation is started, an initial operational test by an accredited inspection body must be arranged in accordance with the Pressure Equipment Monitoring Ordinance. This involves a safety assessment of the pressure vessel with regard to its suitability for the intended operation at the installation site.

Periodic inspection – Subsequently, pressure vessels must be periodically inspected according to their inspection level assigned by the accredited inspection body. The tests are external inspection, internal inspection and main inspection (consisting of external inspection, internal inspection and water pressure test).

Responsibility of the operator – Both the first operational inspection and the subsequent periodic inspections must be arranged by the operator.

Alternative to the water pressure test – If a water pressure test is not possible, there is also the option of carrying out an acoustic emission test. In this case, the tank is checked with the help of a computer. This type of examination is possible both as a substitute for an internal examination and as a water pressure test.

Inspection by operator in case of low hazard potential – Vessels with low hazard potential are to be inspected by the operator himself, e.g. in accordance with the manufacturer’s instructions. However, operator testing may also be delegated to an inspection body.
