Customer-Supplied Pipe Nipple Analyzer Mounting
If you can’t mount the analyzer flush with the process as described under
“Analyzer Flush Mounting (Preferred Method)” – for example, the process wall
is curved sharply, covered with insulation, or obstructed with reinforcing mem-
bers – you can instead:
1. Weld a short 8.89 cm (3 1/2") diameter pipe nipple to the process wall and
make sure to extend the nipple through the skin of the process (see Figure
2-7).
2. Weld the 17.78 cm x 19.37 cm (7" x 7 5/8") supplied plate to the end of the
nipple, taking care to center it over the hole.
3. Wrap the nipple with at least 2.54 cm (1") weatherproof insulation and
heat trace it.
4. Bolt the analyzer to the plate.
If mounting the analyzer using this method, you can also install the probe
heater to minimize the possibility of the sample gas cooling below its dew-
point.
Sensor bolted to mounting plate after
plate is welded to nipple by customer.
