API653 TANK AND
PIPING INSPECTION
Detect defects. Verify integrity. Keep assets operating.
Comprehensive Tank Inspection
External & Internal Assessment
IMIS provides inspection of critical tank components including:
-
Shell plates
-
Tank floors and bottom plates
-
Roof structures
-
Shell-to-bottom welds
-
Nozzles and penetrations
-
Welded connections
-
Foundations and settlement areas
-
Ladders and platforms
-
Internal structures
-
Previous repairs and alterations
Our inspection scope can be tailored around the tank configuration, service history, shutdown requirements and identified areas of concern.
What We Look For
Our tank inspections can identify and assess:
-
General corrosion
-
Localised corrosion
-
Pitting
-
Shell thinning
-
Floor plate degradation
-
Weld deterioration
-
Cracking
-
Leakage
-
Coating breakdown
-
Tank deformation
-
Settlement
-
Previous repair condition
-
Structural deterioration
Identifying these conditions early allows maintenance teams to prioritise repairs and better plan future inspection requirements.
NDT for Storage Tank Integrity
Multiple Inspection Methods. One Complete Picture.
Detailed external and internal examination for corrosion, deformation, cracking, coating deterioration, leakage and other visible indications.
Accurate measurement of remaining wall thickness across tank shells, roofs and accessible components to identify thinning and corrosion.
Leak testing of tank floor welds and repaired areas to identify potential loss of containment.
Detection of surface and near-surface discontinuities in suitable ferromagnetic tank components and welds.
Detection of surface-breaking defects in welds, repaired areas and suitable tank components.
Leak testing of tank floor welds and repaired areas to identify potential loss of containment.
Inspection of critical welds, repairs and alterations to identify defects that may affect tank integrity.
Our API 653 Inspection Process
We review available drawings, previous inspection records, tank history, operating conditions and project requirements.
Our technicians complete the required visual inspection and NDT across nominated tank components.
Inspection results and measurements are reviewed to identify deterioration, defects and areas requiring further investigation.
IMIS provides clear inspection documentation including findings, measurements, photographs, defect locations and recommendations.
Where repairs are required, IMIS can provide additional NDT and inspection support throughout the repair process and prior to return to service.
TANKS WE INSPECT & MAINTAIN
Our inspection capability supports a wide range of aboveground storage assets including:
