Why it matters
Key Benefits
Ultrasonic Testing for Pulp & Paper Equipment Reliability
Our airborne and structure-borne ultrasonic detection program inspects paper machine rolls and bearings, refiners, stock pumps, recovery boiler fans, chip conveyors, and dryer section drives to detect compressed air leaks, steam trap failures, bearing lubrication deficiencies, and partial discharge in switchgear. In pulp & paper environments — hot, humid, and corrosive mill environments with continuous 24/7 production and heavy water usage — extreme moisture and process chemical exposure accelerate corrosion and bearing degradation while continuous operation limits access windows. Our team delivers leak survey maps with estimated CFM losses and ROI calculations for repairs calibrated to the specific failure modes and operating conditions found in pulp & paper operations.
Supporting EPA/OSHA Compliance Through Condition Data
Pulp & Paper facilities operate under EPA effluent guidelines, OSHA combustible dust standards, and boiler/pressure vessel codes. Our airborne and structure-borne ultrasonic detection program generates documented condition records that demonstrate epa discharge compliance tied to recovery boiler and effluent system reliability; combustible dust program for wood handling areas. This audit-ready documentation reduces regulatory exposure and supports your team during inspections and third-party audits.
Reducing Paper Machine Downtime At $15K–$80K Per Hour in Pulp & Paper
Unplanned equipment failures in pulp & paper operations cause paper machine downtime at $15K–$80K per hour, broke generation, and off-spec product. Continuous process with shutdown costs so high that maintenance must occur during brief scheduled outages or on-the-run. By applying airborne and structure-borne ultrasonic detection to paper machine rolls and bearings and other critical assets, our program provides the advance warning needed to schedule repairs during available maintenance windows and protect machine efficiency (uptime × speed × quality) and broke percentage targets.
Context
Challenge & Approach
The Reliability Challenge
Large steam trap populations require systematic survey campaigns. Mill compressed air systems are extensive with leak accumulation across the facility. Paper machine roll bearings operate at low speeds where vibration analysis has limited sensitivity. Wet, noisy mill environments challenge ultrasonic detection if not properly managed.
Our Approach
We survey steam trap populations by system (dryer sections, process heating, tracing) with prioritized repair lists, detect compressed air leaks throughout the mill distribution, assess slow-speed paper machine roll bearing lubrication condition using contact ultrasound, and schedule surveys during normal production for maximum detection accuracy.

Learn More →In pulp & paper operations, our airborne and structure-borne ultrasonic detection program focuses on paper machine rolls and bearings, refiners, stock pumps, recovery boiler fans, chip conveyors, and dryer section drives. We measure high-frequency sound emissions from friction, turbulence, and electrical discharge to identify compressed air leaks, steam trap failures, bearing lubrication deficiencies, and partial discharge in switchgear before they progress to functional failure. Pulp & Paper facilities present specific challenges: continuous process with shutdown costs so high that maintenance must occur during brief scheduled outages or on-the-run. Our program is designed around these constraints, delivering leak survey maps with estimated CFM losses and ROI calculations for repairs that your maintenance team can act on within the scheduling realities of pulp & paper production.
extreme moisture and process chemical exposure accelerate corrosion and bearing degradation while continuous operation limits access windows. In this environment, equipment failures cause paper machine downtime at $15K–$80K per hour, broke generation, and off-spec product. Our airborne and structure-borne ultrasonic detection program specifically targets paper machine rolls and bearings, refiners, stock pumps, recovery boiler fans, chip conveyors, and dryer section drives — the assets where early detection has the greatest impact on machine efficiency (uptime × speed × quality) and broke percentage. We also account for continuous 24/7 production and heavy water usage, adapting our measurement approach to maintain data quality despite these operating conditions.
Yes. Pulp & Paper facilities must comply with EPA effluent guidelines, OSHA combustible dust standards, and boiler/pressure vessel codes. Our airborne and structure-borne ultrasonic detection program generates the condition documentation needed for epa discharge compliance tied to recovery boiler and effluent system reliability; combustible dust program for wood handling areas. Beyond compliance, the condition data drives measurable improvements in machine efficiency (uptime × speed × quality) and broke percentage by converting unplanned failures into scheduled repairs. Most pulp & paper clients see meaningful reductions in paper machine downtime at $15k–$80k per hour within the first 12 months of program implementation.
