A snapshot of complex pipeline interventions completed safely under tight turnaround schedules.
Executed 2,200 bar hydrojetting on a 1.4km underground cooling header, removing 12 tons of calcium carbonate scale and restoring 98% design flow.
Applied 3LPE heat shrinkable sleeves on 420 field welds of a 24” crude oil pipeline with 100% holiday testing clearance prior to backfilling.
Conducted hydrotesting followed by foam pigging and dry air flushing to achieve a certified dew point of -42°C across a 45km natural gas trunkline.
Answers to common technical queries regarding our specialized interventions.
No. Water jetting relies on kinetic shear force to fracture scales rather than abrasive impact. Since water is softer than steel wall material, it cleans down to bare metal without causing metal thinning or surface pitting.
Yes. We utilize specialized ultra-flexible foam pigs and multi-diameter bi-di pigs engineered specifically for unpigged lines containing short-radius bends (1.5D) and restrictions.
We perform grit blasting to achieve ISO 8501-1 Sa 2.5 cleanliness with an anchor profile of 50–90 microns, followed by pre-heating via induction coils to ensure 100% epoxy primer cross-linking.
