Inspection of the sealing weld will require removal of the flange and spectrometer from the
pressure vessel and can be completed as part of regular inspection/maintenance of the
spectrometer and pipework.
Do not use impact (e.g. a hammer) to separate components if the gasket becomes stuck to
the flange and hub.
The lap-joint flange may be manufactured from Hastelloy or stainless steel. Care should be
exercised to ensure that it is not corroded by aggressive chemicals during maintenance or
installation.
5.6. Cradle - ASM1453
A mounting system for the IRmadillo spectrometer is available to simplify the installation
process. The cradle allows for easy installation of the spectrometer into a pipeline with bolting
positions for lap joint flange and hub complying with ASME/ANSI B16.5 or other flange options.
An optional ball valve is also available.
