specified limits as mentioned on the data plate.
3.
No alterations shall be made to this vessel by welding, drilling or any other mechanical
methods without written permission of the manufacturer.
4.
Devices for pressure and temperature control must be attached to this vessel or its piping
system. The devices must protect the vessel against circumstances other than mentioned on
the data plate.
5.
These devices must be designed so that the pressure will not permanently exceed the
maximum allowable pressure PS, except for short pressure surges of 1.1 times the design
pressure.
6.
This vessel has been designed and built to guarantee an operational lifetime in excess of 20
