Paper Machine Dryer Inspection in Green Bay
One of our main areas of expertise is the inspection of paper machine dryer cans. Over the years, we have inspected thousands of dryer cans. All of this work has been done throughout the United States. During the past ten years, we have served on the TAPPI Committee, which formulated the TIS-0402-16 document, “Guidelines for the Inspection of Paper Machine Dryers.” This document along with insurance company requirements states that all dryers be inspected every 5 years. TPS Consulting Engineers, Ltd. in Green Bay uses the latest test equipment to ensure accuracy.
