Two recent case studies involving pulp and paper mills in Ontario and British Columbia, Canada demonstrate the benefit of UltraAnalytix™ inspection. Chlorine dioxide, used to bleach pulp, is particularly corrosive and often results in loss of FRP thickness. The pulp and paper mill in Ontario had … [Read more...] about Case studies: UltraAnalytix™ inspection shows FRP asset relining can be postponed
Non-Destructive Condition Assessment of Fiberglass Reinforced Structures
ABSTRACT: Fiberglass reinforced plastic (FRP) is used in wastewater processing for tanks, scrubbers, piping, ducting and other equipment. FRP often provides better corrosion resistance at lower cost than stainless steel. For some applications, regulators require structural evaluation of containers … [Read more...] about Non-Destructive Condition Assessment of Fiberglass Reinforced Structures
Case Study: Seal Tank (Pulp & Paper)
UltraAnalytix™ inspection results showed that the thickness and condition of the FRP in a pulp bleaching vessel were adequate to postpone scheduled relining. Background: The Owner Company operated a pulp and paper mill in British Columbia, Canada. Five seal tanks are used in the bleach plant, … [Read more...] about Case Study: Seal Tank (Pulp & Paper)
Case study: Relined Upflow Tubes (Pulp & Paper)
UltraAnalytix™ inspection results showed that the thickness and condition of the FRP in a pulp bleaching vessel were adequate to postpone scheduled relining. Background: The Owner Company operated a moderately sized pulp and paper mill located in Ontario, Canada. Chlorine dioxide is used to … [Read more...] about Case study: Relined Upflow Tubes (Pulp & Paper)
Non-intrusive FRP Inspection for Avoiding Premature Asset Retirement
UTComp’s UltraAnalytix system for fiberglass reinforced plastic (FRP) inspection is discussed in an article, Non-intrusive FRP Inspection for Avoiding Premature Asset Retirement, published in the November/December 2017 issue of Inspectioneering Journal. The article, by UTComp president & CEO … [Read more...] about Non-intrusive FRP Inspection for Avoiding Premature Asset Retirement
Damage mechanisms in FRP
Preventing failures and optimizing the service life of any structure is the result of a balance between the service loads applied and the actual capacity of the structure. This is the basis of Fitness for Service or Suitability for Service evaluation. Failure modes relate only to the way that … [Read more...] about Damage mechanisms in FRP
Case Study of Stress Corrosion Cracking of Glass Fibers in a FRP Vessel
One client of UTComp Inc is a large mineral processing facility that requires storage of hydrochloric acid (HCL)at concentrations from 5% to 33% as part of the production process. The subject of this article stores 18% HCL at 200°F. The 35 foot diameter storage vessel is made from FRP using … [Read more...] about Case Study of Stress Corrosion Cracking of Glass Fibers in a FRP Vessel
Using the UTComp System to Monitor Vessel Condition and Restoration
This case describes where the UTComp System has been applied to monitor the condition of a Fiberglass Reinforced Plastic (FRP) tank, recommend repairs to the tank and provide structural data on the repaired tank. At this writing, the FRP tank has been in service for 16 years. It is used in … [Read more...] about Using the UTComp System to Monitor Vessel Condition and Restoration
