The SPX FLOW Tube Self-Inspection process enables you to actively monitor your Scraped Surface Heat Exchanger cylinders throughout their life cycle. Based on your routine and scheduled preventative maintenance program, this program allows you to identify the current tube inner diameter and surface conditions with a series of SPX FLOW recommended procedures and documented measurements. By conducting an efficient self-inspection process, and with the rapid response from SPX FLOW on the final disposition of your cylinder, the pace of refurbishment or replacement is enhanced. Unnecessary shipping and crating costs can be eliminated when the tube final disposition is not aligned with ASME rated pressure and temperature values.

Your participation in the Tube Self-Inspection Program lowers refurbishment costs and increases credits towards new tube purchases. Now, data-driven decisions become faster, easier and less costly with SPX FLOW programs tailored to operating and maintaining your Scraped Surface Heat Exchanger. This program is applicable to only United States and Canada at this time.

Recommended Tools: Starrett Micrometer Model 824D (customer can order qty 1 of 5-6” range or a set) INSIZE Depth Gauge Model 2341-E1 (qty 1)

How To Get Started

STEP 1 Use calibrated telescopic micrometer around the circumference of the tube ID from both the opposite drive and drive end of your Scraped Surface Heat Exchanger.

STEP 2 Measure multiple data points and their locations (distance of data point to tube opening and circumferential position as defined above).

STEP 3 Record three (3) largest tube ID data points in the charts listed above in fields 1-3 for opposite drive end and drive end.

STEP 4 Repeat steps 1-3 using a dial depth gauge with a narrow point locator pin. Record largest measurements in chart above in fields 1-3 for opposite drive end and drive end.

STEP 5 Any unusual scars/gouges should be recorded on this form.

STEP 6 Submit inspection form for data review.
