Installing / Disassembling Pipe Components - ABB Sensyflow FMT500-IG Instrucciónes De Puesta En Marcha

• The materials used must be checked by the user to ensure their suitability for the application
concerned.
• The maximum operating conditions relating to pressure and temperature, as stated on the
name plate / in the operating instructions, must not be exceeded.
• When installing and disassembling pipe components or flowmeter sensors, ensure that the
pipeline has been depressurized.
-
• Before carrying out installation work on pipelines used to carry aggressive or toxic measuring
media, media that may be classed as irritant, or other kinds of hazardous media, the fluids
concerned must be adequately flushed out. Compliance with the relevant accident
prevention regulations must also be ensured.
• If damaged, components must no longer be used. They must be taken out of circulation and
sent to the manufacturer for repair.
• If disassembled components have come into contact with aggressive or toxic measuring
media, media that may be classed as irritant, or other kinds of hazardous media, before
being sent off they must be cleaned and then packed and labeled accordingly.
• If leaks occur at the measuring point, it must immediately be taken out of service.
• Defective gaskets or O-rings must be removed from use and must be replaced as a matter of
urgency.
• The subsequent mechanical labeling or machining of pipe components and flowmeter
sensors can result in damage and is prohibited.

Installing / Disassembling pipe components

• During installation, it is important to ensure that the flow direction corresponds to the
attached label.
• When welding the weld-on adapter, remember to observe the relevant welding instructions.
The amount of heat introduced must be kept to an absolute minimum to prevent warping of
the mounting flange's sealing surface.
• In the case of flanged connections, flat gaskets must be installed. These must be in perfect
condition and resistant to the measuring media.
• Before installing pipe components or flowmeter sensors, check all components and gaskets
for damage.
• Pipe components must not be installed under tension, otherwise the pipeline may be
subjected to impermissible forces.
• When assembling the flanged connections, use screws that offer the required strength and
dimensions.
• The screws must be tightened evenly and to the required torque.
• Once the pipe components have been installed, the insertion connection must be sealed by
means of a blind flange plus gasket or by closing a shut-off device (if present).
CI/FMT500-IG-X1
Exception: If you are using a hot tap fitting.
Exception: Cutting to length and welding onto the pipeline in the case of weld-on
adapters.
