***Safety Notice***

You may be coming into close proximity of energized (active) equipment, evaluate the system and surroundings for hazards. Your survey is a non-intrusive visual inspection. Proceed with the utmost caution.

Click the toolbox and select the Pi/Diameter tape. Once the OD has been determined, use the "Pipe and Flange Measurement Table" in the toolbox to determine the ID.

The ID can be found using any of the following methods:
• Pipe size tables to relate OD to ID
•Flange markings
•Welded stamps on pipe body
•Markings on current expansion joint

It is recommended to use at least (2) methods to validate.

Measure face to face dimension at no less than (4) locations (3 o'clock, 6 o'clock, 9 o'clock, 12 o'clock in this example). Click the toolbox then click the Tape Measurer button. Once measured, record the value in the form.

Click the magnify icons to inspect the expansion joint then click the Expansion Joint Survey icon and check the appropriate boxes. Then click Next to continue.

Inspect the number of Arches and denote on the survey sheet.

Then inspect the Retaining Rings.

Determine the drilling using a combination of the following:
•Stamp on retaining rings
•Stamp on pipe flange
•OD, # of Bolt Holes - Reference the drilling table

Click the hotspots for hints

Now inspect the Control Unit. If there is a Control Unit being used, enter the number of rods being used.

Now inspect the Pipe Run (pipe orientation).

Inspect for tapers and lateral offsets

For this scenario they are both n/a

Evaluate the general disposition of the application ... is it clean, dirty, oily, etc? Is it properly anchored? Is there anything affecting the performance of the expansion joint?

What do you think? You want to be a trusted technical advisor? Is the expansion joint in good working order? If not, what needs to be done?

If replacement is recommended, STAMP data must be obtained.

Talk to and listen to plant personnel ... what is working? What is not? How can we improve our product?

Feel free to make a recommendation ... you are onsite and have the best vantage. Use your field experience. Carry an expansion joint technical manual and match specifications ... the current expansion joint over-engineered? Or under-performing?
