C. Start up Procedure.
4. If not stated otherwise in the instructions for the start up of the vessel, the control
valve must open in such a way that the pressure does not rise more than 5 bar per
minute and the temperature does not exceed the value stated for the start up of the
vessel. Avoid sudden changes in pressure or temperature as they can cause unfavou-
rable tension.
5. Always watch the vessel, valves and fittings during the start up of the system. If a
problem occurs, e.g. leaks or cracks, the vessel has to be closed down immediately.
6. During transport vessels must not be under pressure and they must not contain
media
.
7. When the working pressure is built up, check the vessel and its attachments for
leaks.
D. Operation of the vessels.
8. The vessel must be closed down immediately,
— if cracks appear,
— if there is a leak in a connection that can be disassembled,
— if there is a safety-equipment failure or defect (e.g. clogging of the safety valve)
or a failure of the level meter etc.,
— when there is immediate danger of an accident or a problem if operation conti-
nue,
— if any other unusual phenomena occur during operation whose causes cannot
be found or eliminated,
— if a deformation on the vessel wall occurs,
— if the temperature exceeds the maximum working temperature,
— in all cases stated in the manual that advise the operator to do so.
