The Issue
UGL-Kaefer is contracted to the Longford Gas Plant facility in Gippsland, Victoria. Clearflow was contracted by UGL-Kaefer to pig the heater tubes of a gas fired heater to remove build-up of carbon coke to ascertain their condition and longevity. The tube line was 400m in length with ten 180 degree bends.
The Solution
Clearflow installed pig traps and used specially designed wire impregnated spherical pigs to remove hardened carbon build-up from the 180 degree bends. Similar debris from remaining pipelines resulting in 89-100 percent refurbishment of the internal bores.
