HydroFORM utilizes an ingenious water-column concept that eliminates the need for a wedge, thus providing the benefits of a phased array immersion-tank inspection.
The FlexoFORM™ solution integrates flexible phased array probe technology in a scanner to solve pipe elbow inspection
Tank Floor and Corrosion Under Pipe Support Inspection
SRUT technique was designed to test the annularplate of above ground storage tanks (AST’s) whilethe tank remainsin service.
CUPSorTouchpointcorrosion,is a challenging issue for the inspect thearea without lifting the pipeline or asset off the supporting structure. With SRGW, it is possible to pass the signal through the pipeline at thespecific touchpointarea to effectivelyscreen for corrosion.
Pulsed eddy current, or PEC, is an advanced electromagnetic inspection technology used in detecting flaws and corrosion in ferrous materials typically hidden under layers of coating, fireproofing, or insulation,
Masts and derricks support enormous loads when drilling and running casing. API-recommended practice for mast and derrick inspections is a critical element to avoiding potentially non-productive time or even serious incidents and catastrophic events during drilling operations or following rig reactivation
