CLEARGUARD AUTORDDER
TOXIC SERVICE INSTALLATION
Click anywhere to proceed
In 2013, Clearguard received an enquiry to trial an Autorodding solution on a Toxic service application.
Details
The trial vessel has three tapping points; one in a vapour space that does not block; and two others located in close proximity to each other, that required regular blowing out with high pressure purge to ensure reliable and accurate Pressure Measurement.
The Autorodder was designed, engineered and manufactured in Perth, Western Australia. Once manufactured itwas function and hydro tested, then shipped via air freighted to site, ready for installation.
The trial unit was installed on one of the two tapping points that required constant maintenance.
The purpose of the trial was to compare the Autorodder tapping point against the reference tapping point and standard site tapping point over the three month period.
Prior to Autorodder installation, Clearguard provided in depth training on Autorodder operation and tapping point and impulse line design.

• 50mm diameter Stainless Steel Cylinder, 1000mm stroke Autorodder• 16mm shaft with special 20mm scraper tip that is stroked through the tapping point to clear any blockage• 24VDC battery control system with local position indication, manual test button and timer control• Pressure sealed body with energised packing and special ‘tell-tale’ option to indicate repacking required
Design
Result
The Autorodder maintained tapping point has tracked the reference tapping point consistently and ensured thatthe operators are receiving constant, accurate, reliable pressure measurement readings.The non-Autorodder maintained tapping point has required high pressure blowing with purge at ever increasing frequencies and caused significant production loss on two occasions. The first loss was due to a reduction in process efficiency and the second loss was as a result of the unit being shutdown, both times due to the inaccuracy and lack of confidence in the readings provided by the non-Autorodder maintained tapping point.
