Paper Machine Inspection

Ultrasonic Inspection

Since most paper machine dryer cans are manufactured using a casting process, standard ultrasonic thickness equipment may not provide accurate results. SSS uses fully automated thickness crawlers capable of online velocity adjustments to compensate for the changes in acoustical properties inherent in the casting process. This allows for an accurate thickness scan across the full length of a dryer can. 

Internal Visual Examination

Internal visual examination of paper machine dryers is one of the most efficient and effective  methods of inspection. During a visual inspection, the condition of internal components alon with areas of shell thinning and grooving can be determined. 

Heads, Journals and Bolts

Magnetic particle inspection of the heads and journals of paper machine dryers, along with ultrasonic soundness inspection of the bolts is performed to find defects before they become major problems.
