Corrosion Under Pipe Support (CUPS) Inspection for Safer and More Reliable Industrial Pipelines
Extreme environmental conditions, moisture, chemical contaminants, vibration, and ongoing operational stresses are encountered on industrial pipelines. One of the most difficult integrity risks for industries today is corrosion under pipe support (CUPS) inspection, which occurs under pipe supports that are hard to access for inspection.
Corrosion typically goes unnoticed until a large amount of corrosion has taken place or walls begin to leak. This can cause unexpected downtime, environmental issues, costly repairs, and significant safety risks. Advanced inspection technologies are playing an increasing role in the oil and gas, marine, petrochemical, and power generation industries to ensure that potential failures are prevented by detecting hidden corrosion.
Today, modern inspection methods offer accurate and non-intrusive evaluation solutions that will help in maintaining asset integrity and operational safety in the long term.
Understanding of corrosion under pipe supports
Under pipe support corrosion is caused by water, dirt, salt deposits, and chemicals accumulating between the pipe and the support structure. This forms localized corrosion, which over time diminishes the strength of the pipeline.
A professional pipe support corrosion inspection program can detect these hidden problems early, thus avoiding major structural problems.
There are several factors responsible for the formation of CUPS:
Creating a zone of water retention at the supports
Worn or worn-down protective coatings
Extremely salty conditions in offshore areas
There is poor drainage and ventilation
A vibration and friction that continues throughout
Buildup of substances and sediment that cause additional pollution
These corrosion sites are hard to inspect visually, so special inspection techniques are needed to accurately assess the corrosion.
The role of CUPS Inspection Services is crucial
Corrosion may degrade pipelines' safety and reliability without being apparent. CUPS inspection services can be carried out regularly to help identify the early signs of damage that can progress to a more serious problem before it becomes an issue in the industry.
Key benefits include:
Improved operational safety
Early corrosion detection
A significant cost saving in repair and maintenance
Extended pipeline lifespan
Better regulatory compliance
Reduced unplanned downtime
Periodic inspections are particularly important in older industrial plants and at sea levels where the corrosion rate is greater.
Advanced Technology for UNDER Support Corrosion Detection
New inspection technologies allow for inspection of pipe support areas without extensive loss of the system.
Ultrasonic Thickness Testing (UT)
Under support corrosion detection is one of the most commonly used ultrasonic testing methods. It measures the thickness of the remaining metal and detects areas of corrosion damage to the metal.
Guided Wave Testing (GWT)
Guided waves are used for pipeline inspection, which requires less insulation or pipeline support removal to inspect a long section of pipe.
Eddy Current Inspection
The technique is used to identify surface and near-surface defects in conductive material, without touching it.
Ability to see and inspect with robots
Access to challenging or hazardous areas of pipeline support can be achieved in a safe manner by remote cameras and robotic inspection systems.
Digital Corrosion Mapping
Modern corrosion mapping methods give detailed images of the corrosion patterns for planning and assessment of corrosion risk.
Pipeline Corrosion monitoring plays an important role in asset integrity
It is important to monitor the corrosion of pipelines on a continuous basis to ensure the safety of the industry and avoid unexpected failures.
Modern programs for monitoring aid industries include:
Monitor the corrosion over the years
Forecast maintenance needs
Strengthen the control of assets and their integrity
Minimize the need for emergency repairs
Enhance operational efficiency
The proactive monitoring strategies can help bring down risks and improve the service life of equipment within the facility.
Industries to be inspected by CUPS
Corrosion under supports affects multiple industries where pipelines are in use under harsh conditions.
Oil and Gas Industry
Crude oil, chemical, and gas pipelines must be regularly inspected to ensure that there are no leaks or environmental accidents.
Marine and Offshore Facilities
Support structures of marine vessels and offshore platforms are subject to more corrosion when they come into contact with saltwater.
Petrochemical Plants
The higher the concentration of chemicals, the more likely there is to be hidden corrosion and degradation of the coating.
Power Generation Plants
It is important to regularly inspect steam lines, cooling systems, and high-temperature piping to ensure reliability.
Industrial Manufacturing Facilities
Moisture, vibration, and corrosive chemicals are common sources of problems in manufacturing plants.
Some of the challenges with conventional inspection methods
The conventional method for inspecting for corrosion under supports often has a limited ability to identify the corrosion.
Common limitations include:
Out of the way, concealed support areas that limit access
It is often hard to detect wall loss in a hidden wall
Labor-intensive and expensive to remove the insulation
The potential for downtime whilst inspecting the operation
The hazards of working in restricted and/or elevated areas
