Corrosion Assessment
Corrosion assessment documents deterioration and measured material loss to support maintenance and, when separately commissioned, engineering review.
Overview
Corrosion assessment documents deterioration and measured material loss to support maintenance and, when separately commissioned, engineering review.
NDT Australia provides a single enquiry and co-ordination point for industrial inspection through specialist partners. The proposed provider, personnel competence, method-specific qualifications where required, insurance and any separate approval requirements are checked for the actual scope before appointment; no general accreditation or acceptance guarantee is implied.
Assets & Materials
Accessible tanks, pressure components, pipework and steel structures can be surveyed for general corrosion, pitting and erosion concerns.
Methods & Limitations
Visual observations and identified ultrasonic thickness points form a repeatable condition record. Local survey grids can describe accessible wall loss; automated mapping or concealed-area techniques are not assumed.
Sampling can miss local pits between readings. Insulation, supports, linings and buried sections conceal surfaces; removal or a verified specialist method needs separate planning. Future corrosion rates cannot be inferred reliably from one survey.
Typical Defects & Conditions
- General thinning and local pitting at accessible locations
- Erosion patterns around nominated service features
- Coating breakdown and visible corrosion at interfaces
Planning the Inspection
Describe contents, temperature, exposure, insulation and previous losses. Agree whether the objective is baseline condition, a repeat survey or evidence for a separate integrity decision.
Expected Reporting Deliverables
Reports link condition photographs, thickness locations and measurements to the asset register. Trend comparisons state whether prior data is comparable; any remaining-life or fitness-for-service opinion identifies separate assumptions.

Applications
Corrosion Assessment is applied across a wide range of assets and industries, including:
- Accessible tanks, pressure components, pipework and steel structures can be surveyed for general corrosion, pitting and erosion concerns.
- Inspection planning for water authorities assets and operators
- Inspection planning for manufacturing assets and operators
- Inspection planning for infrastructure assets and operators
Standards & Competence Context
The references below are planning context, not a claim of accreditation, certified compliance or a universal acceptance rule. Confirm the applicable edition, part, material, procedure and acceptance criteria for this asset. Verify the appointed personnel's method, level and sector competence, insurance and any engineering authority required for the scope before work. A method standard is not itself a return-to-service approval.
- AS 3788 — Pressure equipment in-service inspection
- ISO 16809 — Ultrasonic thickness measurement
- AS 2885 — Pipelines integrity (where applicable)
Why Choose NDT Australia
- One enquiry point for scope and specialist-partner co-ordination
