IRISPIG: - IRISPig Inc. Dl. IRISPIG: A new ultrasonic pig for inspection of short, small diameter lines, ie flow lines, production lines and other non-piggable pipes. Instrument consists of self contained modules housing power supply and electronics data acquisition module.
IRISPIG is made to test pipelines that have not been able to be inspected or have been un-economical to inspect by traditional inspection methods. There are other similar systems but they are supported by umbilical cables and have to be winched through the pipe.
Pressure is maintained on sealine to hold batch pig while water is being used to push in.
The inspected section of sea-line was 465m long. Using Viewer program software, the pipe
image is broken into smaller 3m sections. The inspector can then “walk”
along these sections 6mm at a time, looking at the B scan thickness presentation. i.e.
The inspector opens up the condensed image into 3m sections and can scan along these
B scan frame by frame, looking at the ID & OD wall. On screen measure cursors give
immediate thickness readings in addition to the color thickness range codes.
