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.

Excellent Opportunity to Join New & Active Group Sponsored Projects

ETD are planning to start four new multi-client or Group Sponsored Projects (GSPs) at the start of 2018. This is a good opportunity to consider how you can benefit from this offer of being involved in any of these four projects, or a currently running project, for a fraction of the total project cost. Apart from the data and reports/guidelines produced there is much learning through other project partners and experts during the on-going discussions and six-monthly project meetings which partners can attend in person or by Skype/ Video-Conferencing etc.

Details of the projects and the opportunities being offered can be seen by clicking on the image.

ETD's ‘HIDA-7’ Conference – Special Issue now published in the ‘Materials at High Temperature’, journal

ETD Consulting are pleased to announce that following its successful High Temperature Defect Assessment (HIDA-7) Conference on the subject of Life/Crack Assessment and Failures in Industrial Structures, in particular those operating at high temperature, which was held at Portsmouth University in May 2017; edited versions of several of the papers presented at this conference have now been published in the ‘Special Issue of Materials at High Temperature’ journal.

HIDA was originally the acronym for an EU Commission and Industry supported research project, led by Dr Ahmed Shibli of ETD, which aimed to develop a unified European High Temperature Defect Assessment procedure. The Brite-Euram HIDA project involved 11 organisations from 7 countries, with the effectiveness of the procedure developed being demonstrated using material models based on data generated and/or gathered on a number of CrMo(V), 9CrMoVNb and 17Cr12NiMo engineering steels. The original HIDA conference held at CEA (Saclay) in 1998 focused on the themes covered by the Brite-Euram project, and in particular topics concerned with crack growth and accurate assessment of the behaviour of high temperature plant components containing defects and operating under steady and/or cyclic loading conditions. The scope of subsequent HIDA conferences was extended to the consideration of aspects relating to life assessment and condition monitoring, integrity of repaired welds and the characteristics and performance-in-service of newer advanced martensitic steels such as P91 and P92.

The 22 papers included in MHT’s HIDA-7 Special Issue fall under the themes:

  • Deformation and crack growth and their modelling;
  • Life assessment and condition monitoring;
  • Advanced martensitic 9/10%Cr steels;

ETD's Invitation to Join New & On-Going Group Sponsored Projects (GSPs)

In response to the needs of the international industry, ETD Consulting regularly launches new multi-client projects which are open to all.

ETD has excellent expertise through its in-house R&D, plant service/technical consulting and project management experience and links with plant manufacturers, plant operators, service providers and researchers from around the world. The company is thus in an ideal position to conduct such projects on behalf of project partners/sponsors and bring together plant experience from best run plants and the latest technology development in Europe, Japan, USA and elsewhere.

The benefit of joining these GSPs, in which costs are shared, is that each participant gains the data and results of the whole project at a fraction of the total project cost. All work is carried out by ETD and its expert staff/ consultants but the sponsors determine its direction.

ETD Now Provides “Obikou” High Temperature Pipe Strengthening Service

As a result of a partnership agreement with a Power Company in Japan, ETD now offers this unique patented technology service worldwide (including Japan) for the creep life extension of high temperature, high pressure pipelines, especially those already showing creep damage. 

“Obikou” is an on-site service for power, process and other high temperature plant and has shown to achieve creep life extension by a factor of about 4. It simply involves quickly reinforcing a potentially vulnerable or creep damaged pipe with multiple layers of thin high-temperature alloys strip that is wound/wrapped around a pipe thus halting/ reducing the development of creep damage. Details can be seen in the ETD's “Obikou” Newsletter by clicking on the image (right).

References on the R&D work carried out in support of Obikou, Japanese plant experience with Obikou, and other details can be provided on request. Please contact: enquiries@etd-consulting.com.

Launch of a new Group Sponsored Project on Aberrant P91 Inspection, Repair and Life Extension

ETD Proposal No: 1558-gsp-prop17

To read the GSP Outline please click on the Proposal Image.

ETD has launched a new proposal for a Group Sponsored Project. The proposal is entitled 'Early Stage Damage Inspection, Repair & Life Extension of Aberrant P91 Components'. This newly launched proposal is aimed at testing some of the NDE techniques, tried and established in the earlier project, on the P91 aberrant microstructures, It is also looking at testing some newer NDE techniques developed since the start of the earlier project, and, also look at new ideas and technologies for the strengthening and life extension of P91 components which have either developed creep damage or contain aberrant microstructures.

As this is a Group Sponsored Project (GSP) costs are shared between a number of sponsors so each pays only a fraction of the total project cost. 

If you would like to obtain the full proposal or would like to discuss this Group Sponsored Project in more detail, please don't hesitate to contact us

Completed Project on ‘Best Practices for Welding P91 to P91 and P91 to P22 Steels’.

ETD Consulting have recently completed a project on ‘Best Practices for Welding P91 to P91 and P91 to P22 Steels’.

There was an urgent need to weld a new P22 boiler stop valve into a P91 main-steam line, which had been in operation for more than 100,000 hours. ETD was approached by a client for guidance on the current best practices for welding P91 to P91 and P91 to P22 steels. Based on its experience and knowhow, ETD provided a summary of the best practices and guidelines for this critical welding application.
