Integrity Testing

Overview of Integrity Testing Services for Infrastructure Condition Assessment

Integrity testing provides a detailed evaluation of the physical condition and performance of infrastructure assets operating in corrosive and high-demand environments. These services go beyond visual inspection by using quantitative testing methods to measure material loss, coating performance, and structural condition. The data collected allows for accurate identification of active deterioration, hidden defects, and areas of elevated risk that may not be immediately visible.

By establishing a clear understanding of asset condition, integrity testing supports informed decision-making related to maintenance, rehabilitation, and replacement planning. It also provides a defensible technical basis for prioritizing capital expenditures and reducing the likelihood of unexpected failures.

Integrity Testing Methods, Inspection Techniques, and Engineering Capabilities

Corrosion Probe, Inc. provides a range of integrity testing services designed to assess both materials and protective systems under real-world operating conditions. Testing programs are developed based on asset type, exposure environment, and known degradation mechanisms to ensure meaningful and reliable results.

Our services include non-destructive testing methods such as ultrasonic thickness measurements to quantify material loss, holiday detection to verify coating continuity, and adhesion testing to confirm bond strength. We also perform weld inspections, lining inspections, and targeted destructive sampling where laboratory analysis is required to fully understand material condition.

Testing results are documented and interpreted to provide clear conclusions regarding asset condition, areas of concern, and recommended next steps. This data can be integrated into mechanical integrity and asset management programs and used to validate rehabilitation strategies or confirm installation quality.

Applications of Integrity Testing in Water, Wastewater, and Industrial Systems

Integrity testing is applied across a wide range of infrastructure systems including pipelines, storage tanks, manholes, wet wells, lift stations, and process equipment. These assets are often exposed to corrosive environments such as hydrogen sulfide gas, chemical attack, and microbiological activity, which can accelerate deterioration if not properly managed.

Testing is commonly performed during condition assessments, prior to rehabilitation projects, after installation of coatings and linings, and as part of ongoing maintenance programs. It is also used in failure investigations to determine root causes and prevent recurrence.

By providing measurable and objective data, integrity testing supports risk-based decision-making, improves reliability, and helps extend the service life of critical infrastructure assets.

Frequently Asked Questions

Integrity testing uses quantitative methods to measure the condition of materials and systems, while inspection is typically visual. Testing provides objective data such as thickness loss, coating defects, and adhesion strength, allowing for a more accurate assessment of asset condition and remaining service life.
Integrity testing is typically performed during initial condition assessments, before and after rehabilitation work, and as part of ongoing asset management programs. It is also recommended when there are signs of deterioration, performance issues, or when assets are operating in aggressive environments.
Testing can identify material thinning, corrosion damage, coating failures, voids, leaks, and loss of adhesion. It is particularly effective at detecting hidden defects that are not visible during standard inspections but can lead to failure if left unaddressed.
In many cases, testing can be performed while assets remain in service, depending on access, safety requirements, and the type of testing being conducted. This allows for condition evaluation without significant operational disruption.
Results are used to support maintenance planning, prioritize repairs, validate rehabilitation work, and guide long-term asset management strategies. The data provides a defensible basis for decision-making and helps reduce risk associated with unexpected failures.
