Opportunity to join new Group Sponsored Project "Further Development & Refinement of an Electromagnetic (EM) Scanner for the Inspection of P91, P92 and Other Components in High Temperature Plant"

ETD, together with its industry sponsors, are planning to start a new multi-client Group Sponsored Project (GSP) in 2019.

Please click on the image on the left hand side for more information.

The benefit of joining this GSP, in which costs are shared, is that each participant gains the results of the whole project at a fraction of the total project cost.

For further details including costs involved please contact us.

Feasibility Study Phase of this Project Completed and a Proposal for Phase 2 of the project being launched for the development of a hybrid system

ETD, together with its industry sponsors, started a new multi-client Group Sponsored Project (GSP) at the start of 2018. The mere size of industrial plant (such as, for example, power plant boilers and HRSGs, burners, ducting etc.) means that visually examining various parts needs time, costly scaffolding and hazardous climbing. Some preliminary investigations on the use of commercial drones, with basic modifications for safe operation, are now being considered by some industrial plants. Similarly, the use of small robots or robotic arms that can help to inspect difficult to access areas or operate in environments that are hazardous can save cost, money and lives.

The aim of this short term (up to six months duration) feasibility study GSP “Drones and Robots for Inspection” was to investigate automated devices available in the market and those being developed by universities, research institutes or SMEs and make recommendations for appropriate and cost effective devices (which may even be used as consumables, for example, 3D printed drones with light plastic frames and safety cages) for industrial inspection. Please click on the image to see a brief of the proposal.

The benefit of joining this GSP, in which costs are shared, is that each participant gains the results of the whole project at a fraction of the total project cost.

The feasibility study phase of this project has now been completed and a proposal for phase 2 of the project is being launched in 2019 which includes the development of a hybrid system.

For the detailed proposal and costs involved please contact us.

Also in this newsletter you will find useful and interesting information on ETD’s unique Services for New & Running Plants involving Inspection, Monitoring, Assessment & Life Extension Services using various state-of-the-art techniques like Scanning Force Microscope (SFM) for early stage damage detection, Miniature sample removal (boat sampling) for quality checks and life/condition assessment, Precision Portable Hardness Tester (known as ‘Smart Sleeve’), ‘Obikou’ for Pipe Strengthening and Life Extension and Defect/Crack Assessment.

Offer of Unique P91, P92 Services for New & Running Plants

In this P91/P92 Services Brochure you will find useful and interesting information on ETD’s unique P91, P92 Services for New & Running Plants. These include:

a) Inspection, Monitoring, Assessment & Life Extension Services: Over the last decade through its collaborative research programmes, with its international industry partners, involving large pipe testing ETD has developed a suite of specialist inspection and monitoring techniques and life assessment methodologies that it offers to plants worldwide. These are offered in addition to the conventional NDE techniques for the detection and sizing of defects, together with replication and portable hardness testing for component condition and remaining life assessment. ETD carries out code-based calculations of creep life using either deterministic or probabilistic (another of ETD specialities) methodologies. Examples of these techniques include: Scanning Force Microscope (SFM) for early stage damage detection, Miniature sample removal (boat sampling) for quality checks and life/condition assessment, Precision Portable Hardness Tester (known as ‘Smart sleeve’), ‘Obikou’ for Pipe Strengthening and Life Extension and Defect/Crack Assessment.

 b) Root Cause Failure Analysis: Over the years ETD has developed an expertise in the root cause failure investigation of P91 and P92 components/welds. In the recent past, ETD has investigated a range of failures of T91 tube components and welds, and cracking in P91 pipes and drain-line components in conventional boilers and HRSGs. In these investigations, ETD identifies the root cause of the damage, and proposes remedial actions and solutions to the problem.

c) Consultancy & Guidelines on Materials & Welding: ETD provides P91 and P92 users with advice and guidance on the metallurgy, welding and heat treatment of these steels. This service includes reviewing weld procedure specifications (WPS) for similar and dissimilar metal welds, inspection of NDE records, and guidelines for repair welding of P91. The advice is provided to both the plant operators and designers/ manufacturers. This advice is based on ETD’s P91 experience in a number of Group Sponsored Projects including its running of the International P91 Users Group (Int. P91UG) for international industry over more than a decade and its involvement as consultants to many a power plants worldwide.

Dr Malgorzata Wiatros-Motyka of IEA Clean Coal Centre, UK, shares her thoughts on ETD’s Int. Conference on ‘Power Plant Flexibility’ held in London in July 2018

ETD successfully hosted a 3-Day Conference on ‘Power Plant Operation & Flexibility’ in July 2018 at The Institute of Materials, Minerals and Mining (IOM3), London.

The overall aim of this Conference was to provide an international forum for the exchange of knowledge, information, experience and data where possible. Hence plant owners and operators were the prime audience in this conference. It also attracted several researchers, plant manufacturers and inspection bodies. The underlying aim was ‘how to reduce costs associated with plant maintenance and cycling’. Key aspects were engineering design and materials R&D, cost analysis and plant management/ maintenance.

Dr Malgorzata Wiatros-Motyka of IEA Clean Coal Centre, UK, shared her highlights from the Conference and posted them on the IEA Clean Coal Centre website. To see her thoughts, please click here.

Renting of Electrical Discharge Sampling Equipment to a client for a project in Asia

EDSE (2).jpg

ETD was approached by a European based company to rent their Electrical Discharge Sampling Equipment (EDSE) for a month to cut samples from a power plant in Asia.

The EDSE was developed by ETD in collaboration with international partners to aid in the condition and life assessment of components. The sampling of in-service components has long been seen as an effective way of determining actual material properties and sub-surface material condition. However, many of the existing methods of sample removal require mechanical cutting which can deform the surface and usually require weld repair. Unlike the traditional mechanical ‘boat sampler’, with EDSE, the surface damage if any is of the level of only a few microns. EDSE can also be used to cut out specimens for small punch testing and miniature creep, fatigue or tensile testing for more accurate quantitative life assessment.

The EDSE is available to rent or for purchase. For more information on our EDSE services, please click here.
