ASSEMBLING AND ERECTION.
11.3.1
ERECTION CONDITIONS.
The pressure equipment shall be so installed that employees, operators or third person will not be
endangered.
Minimum safety distances as prescribed by local or national legislations shall be respected.
The pressure equipment shall be installed in such a way that:
•
Inspection openings will be accessible.
•
The nameplate is conspicuous wherever practicable.
•
Access to and operation of controls is possible.
•
All hot parts that can be touched or approached by the operator are properly shielded or insulated.
•
Outlet openings of safety accessories
(e.g. safety valves, pressure relieve valves)
or drains are directed
to a safe area.
Suitable foundation for the specific pressure equipment shall be provided to avoid deformation or sagging
due to its own load, its content or any other external loads e.g. resulting from traffic or other machinery,
wind, etc….
The pressure equipment installation shall be protected from access by unauthorised persons.
Protective measures shall be provided when in case of a fire the safety of the pressure equipment or its
controls and/or safety equipment may be endangered.

CONNECTING AND PREPARING THE PRESSURE EQUIPMENT.
The external connections shall be made to the connection points provided on the equipment, avoiding any
supplemental or fatigue loads or bending moments.
Any welded connection directly to the pressure equipment shall be made by qualified welders according to
qualified procedures and those welds shall be inspected and tested per local Regulations or Codes.
Bolted connections shall be diametrically and gradually tightened with a calibrated torque wrench and torque
load shall be appropriate for the bolt size and type.

chemicals or other aggressive products that may attack the materials, gaskets, instruments etc…
11.3.3
SAFETY AND PRESSURE ACCESSORIES.
To avoid that the allowable relevant operating condition such as pressure and/or temperature, level and/or
volume, etc.. can be exceeded, suitable measuring, control and limiting devices shall be provided and
installed.
Control devices :Suitable manual or automatic regulating devices to maintain all operating parameters within
the normal operating conditions shall be installed. E.g. pressure switches or transmitters, temperature
switches or transmitters, level switches or transmitters etc…
Monitoring and limiting devices :Relevant operation and parameter specific monitoring instruments and
alarm devices shall be provided. Limiters shall prevent that the maximum allowable operating parameters are
exceeded and require a manual reset intervention of the operator after solving the problem and before again
taking in operation the equipment.
Safety accessories :Suitable safety devices shall be installed to prevent that the maximum allowable
operating parameters are exceeded in case of failing limiting devices.
