I am seeking a method to accurately measure wall thickness in pipeline transportation. Our process involves using 8" schedule 80 pipe to convey raw materials for glass melting.
Interested in learning more about intelligent pigging or UT from an external source?
Tony, considering that your final output is glass, it can be assumed that the materials being transported are abrasive in nature. However, it is not specified whether the transportation medium is compressed air, water, or another fluid. Assuming that high transport velocities could lead to increased wear rates, it is recommended to use a liquid medium such as water. In the absence of information regarding the pipe's layout, it is presumed that the pipeline includes bends and slopes. To address potential wear issues, it is advised to set up ultrasonic measurement points at bends and elbows where wear is typically higher. Monitoring wall thickness trends through a database of readings can help identify potential areas of concern. For underground pipelines, conducting wall thickness measurements using radiographs is a more costly but effective method. Additionally, employing a magnetic particle catcher at the water separation unit can help detect wear particles and assess the extent of wear along the pipeline. In situations where intelligent pigs are considered for inspection, it is important to ensure that the pipeline is designed to accommodate such tools. While intelligent pigs can be costly, they can be justified in specific scenarios where thorough inspection is required.
Vee shared a remarkable post discussing the importance of checking wall thickness and ensuring proper installation engineering when selecting the most suitable metalurgy for your application. It is crucial to stay updated on the latest technology trends to find the best alloys available for tackling high-abrasive materials.
Based on Tony's post, I assumed the pipe has already been installed. If considering a redesign for cost effectiveness, opting for durable alloys is a wise choice. However, I also recommend exploring the affordability of rubber lined pipes as an alternative option.
You might want to consider using Ultrasonic Thickness Gauging; it's a non-destructive testing (NDT) method that accurately measures wall thickness by sending an ultrasonic wave through the material and calculating the time it takes to reflect back. This technique is especially effective for pipeline systems as it can detect internal and external corrosion or erosion that often lead to wall thinning. You might need a skilled operator for precise measurements, but it's been widely adopted in industries that heavily rely on pipelines. It's also safe to use around your raw glass materials.
You may want to consider ultrasonic testing (UT) for wall thickness measurement. It's a non-destructive method that uses sound waves to measure wall thickness, which would be ideal for your application in raw material transportation. It's accurate, reliable and can provide detailed information about potential issues like internal or external erosion, corrosion, etc. Also, there are portable devices available in the market that offer great mobility and ease of use. Plus, it can safely measure without interrupting your process or service.
You might want to look into ultrasonic testing devices. These instruments utilize high-frequency sound waves to measure wall thickness accurately. They're non-invasive and they provide real-time measurements, which is ideal for an ongoing process like yours. Additionally, these tools are portable and can measure different material types, making them quite versatile for your application in conveying raw materials for glass melting. Make sure you get one designed for high-temperature environments if your pipes are heated.
