TCR Arabia offers Short Wave Guided Wave Ultrasonic Techniques

TCR Arabia (www.tcr-arabia.com) in conjunction with its international partners now offers Short Range Guided Wave Ultrasonic Technique (SRGUT) which has been designed to test the annular plate of above ground storage tanks (AST’s) while the tank remains in-service.  The technique is based on the concept of pulsing guided laminar waves into the base material from the chime area.  The waves propagate up to three feet into the annular plate.  When corrosion, pitting, erosion are present the ultrasonic waves mode convert and are received by the same transducer. 

The technique is also being used to test for corrosion under pipe supports, corrosion at soil air interfaces, and similar difficult to access locations.


The above figure depicts the transducer placement on the chime plate propagating long range ultrasonic waves into the annular plate.  The sound reflects at top side or underside corrosion providing a c-scan image of the defect.  The signal strength at the defect provides evidence of the depth and overall morphology of the defects.


The above figure provides a visual presentation of the collected data providing distance inspected, with of inspection along with details on the indications identified.

Some limitations exist when using this technique to including:

•    Top or Bottom Side Differentiation
•    Must Have 2” Space for Probe Placement


•    Tank Floor Annular Plate Testing
•    Testing Concrete Coated Interfaces
•    Testing Under Pipe Supports
•    Tank Dyke Piping Interfaces
•    Scan Under Vessel Supports

Short Range Guided Wave Testing has become a proven and reliable technique as one method for determining the integrity of tank annular plates where the highest probability of corrosion exists to help prioritize out of service tank maintenance requirements.

Paresh Haribhakti and Rohit Bafna conduct Metallurgy training for Group Five Pipe Saudi Ltd Co.

Representing TCR Arabia (www.tcr-arabia.com), Mr. Paresh Haribhakti and Mr. Rohit Bafna conducted training on “Metallurgy for Non-Metallurgists” for 3 days in April 2011. This training was conducted at the office premises of Group Five Pipe Saudi Ltd Co.

This dynamic three-day course for non metallurgists, including designers, engineers, technicians, sales engineers and purchasers, is designed to give your company a strong competitive edge in today's rapidly changing marketplace.

The course focus is on translating complex principles and procedures into easy to understand terms that will enable participants to gain a valuable working understanding of the fundamental principles of metallurgy as well as the basic structure, properties, heat treatment and processing of metals and alloys.

Metallurgy pervades the full gamut of engineering product design and processes.   It is the basis from which optimum properties for a given design are determined. Product life and maintenance are key issues in all manufacturing product design using metals. Component properties must be adequate to ensure the desired product life in complex environments involving wear, corrosion, and elevated temperatures. Metallurgy is thus a vital basis of every major engineering field, and it contributes to virtually all engineering applications where a metallic component or system experiences use.

Adapting Materials and Energy.   Lawrence Van Vlack's text "Elements of Materials Science and Engineering" defines engineers as "those who adapt materials and energy for society's needs." This definition goes a long way in emphasizing the vital importance of an understanding of materials to today's design engineer. Compounding this importance is the rapidity of technological change in our emerging global society -- both in the design of materials themselves -- and the demands placed upon those materials by product performance requirements.

Bridging the gap between theory and practice.  TCR's "Metallurgy for Non Metallurgists" course takes the mystery out of metallurgy! Participants gain an understanding of the field, technical familiarization with metallurgical terms, an overview of the material selection and processing parameters to obtain optimum properties for a given design, and how to apply them to save money, increase profitability, and enhance customer satisfaction.

Practical training with significant benefits.   This interactive, highly practical course will be of significant benefit to anyone who needs a working understanding of metals and their applications, those with no previous training in metallurgy, technical, laboratory, and sales personnel, engineers from other disciplines, management and administrative staff, and non-technical support staff. Participants will gain a technical familiarization with ferrous and non-ferrous metals and their processing and optimization to meet specific product needs. Emphasis will be given to the foundational concepts of metallic structures and phases and the latest developments in material processing, in combination with an overview of metallurgy, which will provide a solid foundation and understanding of the significance and impact of metallurgy in product design, whether you:

Are seeking ways to cut costs, improve performance and increase profitability.

Have employees who want to learn more about complementary or competitive technologies.

Have employees who want to update present knowledge of metals, processing, and optimization.

Have employees who are just starting out in the field and need a basic knowledge of metallurgy.
