Note that the equipment is also used incorrectly if the materials of the equipment are not suitable for
the fluid.
The equipment is also considered to be used improperly if:
the equipment is not in proper working condition when being used the equipment is operated or serviced by
unqualified personnel. The personnel must have the necessary qualification and experience for
the required work.
Basic safety notes Explosion hazard Explosion risk if equipment is used that is not
suitable for the environmental conditions. When using the equipment in explosion risk areas
make sure that:
The permissible surface temperature of the equipment for the place of installation must
not be exceeded.
If electrically insulated equipment is installed appropriate measures must be taken to
discharge any static electricity between pipe flanges.
The heat generated by friction caused by moving parts that do not run smoothly can
cause explosions. Make sure that all moving parts can operate smoothly.
When carrying out welding work in order to install or remove the equipment flying sparks
may be generated that can cause fire or explosion. Observe any on-site regulations for
fire and explosion prevention.
Only qualified personnel is allowed to mount or remove the equipment or its components.
The mechanical strength of the equipment is designed for DN 25 end connections. If the pipe
end connection load exceeds the strength limit for DN25 there is a risk of explosion. In this
case take appropriate measures to provide additional support so that the pipe end
connection load does not exceed the strength limit for DN 25.
Risk of severe injuries The equipment is under pressure during operation and may be hot. Before carrying out
any work on the equipment make sure that the following requirements are met:
The pipes must be depressurized (0 bar).
The fluid must be completely removed from the pipes and the equipment.
During work on the equipment the installation must be switched off and
protected against unauthorised or unintended activation.
The pipes and the equipment must have cooled down to room temperature (approx.
20 °C).
If the equipment is used in contaminated areas there is a risk of severe injuries or death caused
by harmful substances in or on the equipment.
Before working on the equipment make sure that it is completely decontaminated. Always
wear the protective clothing prescribed for contaminated areas when working on the
equipment.
The equipment must only be used with fluids that do not attack the material and the gaskets
and sealings of the equipment. Otherwise leaks may occur and hot or toxic fluid could escape.
The equipment and its component parts must only be mounted or removed by qualified
personnel. A qualified person must be acquainted with and experienced in the
following:
Making pipe connections.
Selecting suitable lifting gear and understanding the rules for its safe use.
Working with dangerous (contaminated, hot or pressurized) fluids.
If the admissible temperature and pressure limits are exceeded the equipment may be
destroyed and hot or pressurized fluid may escape. Make sure that the equipment is only
operated within the admissible service range and limits.
For more information on limits and pressure & temperature ratings see name plate and the
section "Technical Data".
