Conference Papers

As a FRP Subject Matter Expert, Geoff Clarkson frequently speaks at conferences to teach people about the benefits of FRP, assisting customers to make the right design decisions and explain UltraAnalytix, our non-destructive and non-intrusive FRP Testing System.  UltraAnalytix structural information about fiberglass reinforced plastic (FRP) – similar to Acoustic Emission – without the significant limitations.  Through our proprietary, advanced methods, readings taken using conventional ultrasonic equipment are used by UltraAnalytix to determine the structural condition and capacity of the material surveyed, including the presence of delamination, some resin changes and condition of the resin-to-reinforcement interface.  This differs significantly from conventional ultrasonic evaluation of metallic components – there are no known equivalent methods or standards for metallic evaluations.

Below is a selection of papers presented by Geoff Clarkson at conferences around the world.

Using Ultrasonic Technique to Determine Fitness for Service of FRP Equipment for Chemical Handling Applications

Authors: Pradip Khaladkar, PECT and Geoff Clarkson, UTComp

Fiberglass reinforced plastic materials are well suited to a wide variety of chemical handling equipment
where resistance to corrosion is required. A significant impediment to adoption of these materials for
many suitable applications lies with the inability to do a fitness for service determination after the
equipment and piping have been in service. This is largely due to the lack of effective non-destructive
and non-intrusive techniques for plastic materials. This paper presents a case study of a fiberglass
reinforced plastic scrubber which was evaluated with a novel ultrasonic technique followed by a
destructive evaluation for retained mechanical properties and corrosion barrier condition. When
compared, the results showed good correlation. Although the FRP unit was already discarded this
study indicated that significant life had still remained.
Key words: Non-destructive testing, FRP, corrosion barrier, fitness for service

Using Ultrasonic Technique to Determine Fitness for Service of FRP Equipment for Chemical Handling Applications

Lead Author: Pradip Khaladkar

Fiberglass reinforced plastic materials are well suited to a wide variety of chemical handling equipment where resistance to corrosion is required. A significant impediment to adoption of these materials for many suitable applications lies with the inability to do a fitness for service determination after the equipment and piping have been in service. This is largely due to the lack of effective non-destructive and non-intrusive techniques for plastic materials. This paper presents a case study of a fiberglass reinforced plastic scrubber which was evaluated with a novel ultrasonic technique followed by a destructive evaluation for retained mechanical properties and corrosion barrier condition. When compared, the results showed good correlation. Although the FRP unit was already discarded this study indicated that significant life had still remained.

Model to Optimize the Design of Fiberglass Reinforced Plastic in Chlorine Dioxide Service

Model to Optimize the Design of FRP in CLO2 Service: Paper

Model to Optimize the Design of FRP in CLO2 Service: Presentation

Fiberglass reinforced plastic (FRP) is used for tanks and pipe to contain a wide range of corrosive vapors and liquids – in many cases with superior performance and lower cost compared to stainless steels.  When designing metallic tanks and piping, the dominant and simplest damage mechanism is thickness loss due to corrosion and design standards are well developed. Assessment of steel structures is based primarily on the existing fitness for service (FFS) of the steel.   FRP experiences a number of simultaneous damage mechanisms that affect its structural capacity.  Design conventions and conventional practice for FRP defines the layers nearest the process-side of the FRP as the only component that is important for its fitness for service.  Based on extensive inspection history in similar services, this paper presents a model for design of FRP in chlorine dioxide service to optimize the life and maintenance of FRP assets.
