Infrastructure and Equipment Need Protection from Corrosion

Existing installations are at high risk when signs of corrosion are exhibited. Typically, corrosion originates from electrical, electrochemical, chemical or bacterial interaction with the components and requires specific analyses.

A corrosion survey will result in a significant reduction of the costs generated by corrosion. Once your requirements are clear, we start with basics by developing first the corrosion survey scheme considering the specifics of the structure or asset at hand.

While formulating corrosion survey scheme, review of the available as-built documentation, drawings and other investigations are undertaken.

ASSESSMENT DURING CORROSION SURVEY

In order for the engineer to develop a full and detailed understanding of the type and condition of materials, construction and defects exhibited by the structure under examination, the type and extent of survey and testing undertaken will be prescribed. It is expected that direct inspection and testing will be required. This may include destructive and non-destructive testing [NDT] and sampling as well as laboratory analysis.

The corrosion survey on-site generally starts with assessment which include:

• Visual Survey and Assessment
• Half-cell Potential Mapping
• Corrosion Rate Measurement
• Water and Soil sampling
• Close Interval Potential Survey [CIPS]
• Direct Current Voltage Gradient [DCVG] Survey

We put our experience, qualified and dedicated personnel to determine the probable cause of deterioration through interpretation of the available documentation, survey and test data.

The qualified inspectors are well competent in various construction codes, various NDT techniques, mechanical tests, various damage mechanism, welding and corrosion of metals having qualification in ASNT, AWS, CSWIP and NACE.
