4.2.5 Installation of the purging tubes
Note
The purging tubes are unsymmetrical with slanted ends and must be mounted such that the
larger side of the tube end points against the direction of the process flow.
The purging tubes ① are mounted by clamping the purging tube flange ⑤ between the
customer flange
② and the SITRANS SL process interface ④. The sealing is accomplished
by the two process gaskets
③ as shown in the following figure.
When using an ANSI 4"/150 lbs process interface the purging tubes
① have to be clamped
between the ANSI 4" adapter flange delivered with the system and the process interface
④.
