For facility managers and maintenance teams across Arizona, aging infrastructure presents an ongoing challenge. Pipelines that have been in service for decades often develop hidden defects that can lead to costly leaks, emergency repairs, and unplanned downtime. One of the most concerning issues is Corrosion Under Insulation (CUI), which can remain undetected until significant damage has already occurred.
Traditional inspection methods often require removing insulation, erecting scaffolding, or taking systems out of service. These processes consume valuable time and resources, especially during planned shutdowns. That is why Code Steel Industrial Inspections has implemented Guided Wave Inspection (GWI) as an efficient and cost-effective way to evaluate pipeline integrity.
The Challenge of Inspecting Aging Piping Systems
As pipelines age, corrosion can develop on both the interior and exterior surfaces of the pipe. Unfortunately, these issues are not always visible during routine inspections. For reliability managers, maintenance supervisors, and turnaround planners, the risk of a hidden defect becoming a production-stopping failure is a constant concern.
When every hour of downtime affects productivity and revenue, expanding a shutdown window to inspect miles of piping is rarely an attractive option. Facilities need a solution that provides meaningful data quickly while minimizing operational disruption.
What Is Guided Wave Inspection?
Guided Wave Inspection is an advanced, non-destructive testing method designed to assess long sections of pipe from a single access point. Using specialized sensor collars, low-frequency ultrasonic waves travel through the pipe wall and identify areas where corrosion, cracking, or wall loss may be present.
Depending on the pipe diameter, insulation, and coating conditions, Guided Wave Inspection can evaluate up to 200 feet of pipe in either direction from the testing location. This allows inspectors to screen large sections of piping without removing extensive insulation or interrupting normal operations.
GWI is particularly effective for identifying:
- Corrosion under insulation (CUI)
- Circumferential cracking
- Large corrosion pits
- General wall loss
- Hidden defects in difficult-to-access areas
Because the technology can often be performed while systems remain in service, it is an ideal solution for facilities looking to maximize maintenance efficiency and reduce downtime.
Faster Inspections, Better Decisions
Finding potential defects is only the first step. Facility managers need information they can act on immediately.
At Code Steel in Arizona, Guided Wave Inspection results are delivered with clear, detailed documentation that pinpoints the location of identified indications. Rather than providing generic observations, we help clients understand where potential issues exist and how those findings relate to industry acceptance standards.
For example, our reports can identify a defect’s location relative to specific flanges, valves, or other reference points, allowing maintenance teams to quickly prioritize repairs and plan corrective action.
Experience That Extends Beyond Inspection
Successful asset integrity management requires more than simply identifying problems. It requires understanding how those problems impact operations and determining the most effective path forward.
Code Steel brings extensive experience across multiple industries and infrastructure environments. Our team has worked on everything from aircraft and pipelines to chemical facilities, bridges, dams, and marine applications. This broad industry perspective allows us to provide practical recommendations that support both safety and operational goals.
When critical assets are at stake, having experienced professionals who understand real-world inspection and repair challenges can make all the difference.
Make the Most of Every Maintenance Window
Whether you are planning a turnaround, evaluating aging infrastructure, or looking for ways to reduce the risk of unplanned failures, Guided Wave Inspection provides a practical solution for assessing pipeline integrity without unnecessary disruption.
By identifying hidden corrosion and other defects early, facilities can extend asset life, better prioritize maintenance budgets, and avoid costly emergency shutdowns.
If your facility is located in Phoenix, Chandler, Mesa, Gilbert, Glendale, or anywhere else in Arizona, Code Steel can help you assess the condition of your pipelines, identify potential issues before they become costly failures, and develop a proactive inspection strategy to keep your operation safe, reliable, and running efficiently.
