range.
Sensing element chamber and housing design shall be such that element failure does not
cause the housing to become pressurised. Where appropriate to meet this requirement,
a blow-out disk shall be provided preferably in the bottom of the housing.
Materials (including bolting) for in-line instruments shall be, as a minimum, in accordance
with the piping specification and shall be compatible with and appropriate for the
production stream. However, where suitable, an appropriate grade of stainless steel may
be used for the internal trim and/or body.

The use of brass or copper bearing alloys shall be avoided where possible. The use of
aluminium for instrumentation bodies/casings shall be only permitted if available as
“Marine Grade”, low copper, and the combined magnesium and titanium content is less
than 0.6% and the surface is coated to prevent corrosion from the environment and
sparking by abrasion with iron objects..

7.4.3. INSTRUMENT PROCESS CONNECTIONS & HOOK-UPS

The process connections on all non-flanged instruments shall be ½” NPT, while flanged
instrument connections such as thermowells shall be ANSI 150# RF as a minimum.
The process hook-up shall utilise integral single block and bleed units at the instrument
process tie- in. Double block and bleed units shall be used for severe service. The
instrument, if mounted remote from the process line, shall be connected using impulse
tubing and compression fittings. At the instrument, an instrument manifold (2 or 3-way
manifold for pressure, 5-way manifold for differential pressure) shall be fitted for
calibration. Furthermore, it shall be possible to remove the instrument whilst leaving the
instrument manifold, impulse tubing and compression fittings in-situ

7.4.4. INSTRUMENT TUBING & FITTING

All tubing and fittings shall be of imperial size. Materials shall be 316 SS.

7.4.5. NAMEPLATES
Nameplates and tags shall be provided to properly identify each piece of instrumentation
equipment. This information is to be stamped or engraved on a permanent 316 stainless
steel plate affixed to the equipment in a permanent manner. Lettering shall be a minimum
of 12mm high. The nameplate shall provide the following data as a minimum:

• Tag number
• Manufacturer’s name, model number, serial number

7.4.6. SURGE PROTECTION

Additional surge protection device shall be provided for electronic equipment which
has direct connections to telecommunication tower devices or installed at outdoor with
high elevation, such as telecommunication system and CCTV system.
