Chintan Shah , Automation Client AddedFriday, March 11,2016 at 4:52 PM looking to automate Pipe ID measurement system with better coverage of product Hi All, We are looking to automate measurement of 30 feet long pipes. We are currently using CMM but that does not cover whole pipe ID. Any other ideas? We will be interested in buying a solution too. Answer Answer The Question Write your answer here Submit Cancel Reset Sort By Default not available Answered Friday, March 18,2016 at 12:28 PM In the pipeline inspection world we use what's called a deformation tool to measure the ID of a pipe. The tool is feed through the center of the pipe either by the pressure in the pipe line or it's pulled through with a long tether. It has lots of little arms on it that slide along the inside of the pipe and measure changes in the internal diameter. It's a pretty complex solution but there may be some variation on this that you could use. Dan Penczak , Control & Power Systems, Inc.

Determining whether a traditional external device (ultrasonic) can deliver the accuracy required would be step one. If not, more advanced measures can be considered, but come with a whole host of other considerations. X-ray for example would potentially handle it, but this would be expensive and introduces guarding challenges, etc. We have integrated 'pipe crawler' solutions that could be utilized and potentially offer a more appealing price point for a very accurate system. Understanding the material, size, and process would help drive more specific answers. Arun Sinha , OPTO 22 Answered Thursday, March 17,2016 at 7:54 PM Inner Diameter measurement in a pipe or tube I think is less common. There are sensors out there that do a combination of OD and Thickness, via ultrasonic technology...so this could get you there. Other people have talked about getting the data and what to do with the data. I think that part is less challenging versus getting the a sensor that can take the measurement. Once you have an output for the sensor (0-10VDC, 4-20mA) any of us PLC/PAC manufacturers in the Exchange can help you take it from there (historical data, control scheme, HMI etc.). But as mentioned, start with figuring out the sensor first.

We have come across some fairly high end gear before in the plastics industry that does pipe ID for PVC using ultrasonics. http://www.zumbach.com/pdf/Literature/UMAC-WALLMASTER/PIPE-WALLMASTER_UMAC.002.0002.E.pdf Marco Pinedo , WIIC Solutions Answered Thursday, March 17,2016 at 6:07 PM There are several ways to do this measurement. The main questions you have to answer is, What will you do with your measurement and How will you implement the solution and/or control to your actual process. We can help you to find out the best solution that fits your needs. Shawn Ebersole , Canary Labs, Inc. Answered Thursday, March 17,2016 at 5:44 PM You would also need to consider how you are going to capture and store your data. There will more than likely be a need for a data historian to collect and store the data, as well as a good trending tool to visualize the data. Please let me know if you have any questions related to our historian and trending solutions. I can be reached at (814) 793-5522 or via email at firstname.lastname@example.org. James A. Campbell , Viewpoint Systems, Inc. Answered Monday, March 14,2016 at 7:32 AM There are several methods for measuring the OD of a pipe. You can also assess concentricity. Accuracies can reach 0.001 inch levels. A pipe of that length will require either a lot of sensors or movement of a sensor along the length of the pipe. Can you describe more detail about your accuracy, precision, takt time, and pass/fail requirements?
