What is internal inspection of a pressure vessel?
Internal inspection of a pressure vessel is a detailed examination
of the inside surfaces and internal components of the vessel to
assess its condition, safety, and structural integrity. This type
of inspection helps identify hidden defects that may not be
visible during external inspection.
In India, internal pressure vessel inspections are commonly
carried out in industries such as manufacturing, chemicals, oil &
gas, pharmaceuticals, and power plants, in line with safety
requirements under the Factories Act, 1948 and applicable state
factory rules.
Internal inspection typically includes:
- Examination of internal surfaces for corrosion, pitting, and erosion
- Checking for cracks, scaling, or material thinning
- Inspection of weld joints and seams from inside the vessel
- Assessment of internal fittings, trays, or components (if present)
- Verification of cleaning condition and residue buildup
- Identification of any deformation or structural weakness
This inspection is usually carried out during shutdowns when the
vessel is depressurized and made safe for entry.
