Advanced Creep

Coordination of Advanced Creep Activities to Improve Safety and Durability of High Temperature Plant Materials

 

 

European Creep Collaborative Committee (ECCC)

ECCC is a voluntary grouping comprising, at present, of some 16 countries involving over 40 European organisations. More European countries and organisations can join ECCC after signing a simple Memorandum of Understanding (MOU) to exchange information and data from their projects.

ECCC was formed in 1991 to co-ordinate Europe-wide development of creep data for high temperature plant. During the period 1992-1996 ECCC concentrated its efforts, through the European Commission supported Concerted Action BE 5524 'Creep' on the coordination of projects and data dealing with rupture strength data development for parent metals. This Concerted Action (CA) resulted in the development and publication of the European guidelines on harmonised data generation, exchange and assessment methods and in the publication of approved data sheets on a scale that had not been possible before. This project was followed by the European Commission supported Thematic Network BET2-0509 'Weld Creep' (1997 - 2001). This Thematic Network (TN) dealt with harmonisation of generation, exchange and analysis of creep rupture data for welded materials. Following this success with basic creep data harmonisation (such as rupture strength of various steels, weld strength reduction factors etc.), the ECCC consortium has now identified the Advanced Creep activity as the next important requirement for the safe operation of high temperature plant components and for input to European codes and standards bodies.

ECCC provides an excellent platform for co-operation of European industry and research in the harmonisation of data for materials operating in the creep regime. This data is then provided to the European Standards bodies as agreed European data. ECCC frequently produces guidelines for the generation, treatment and assessment of large creep datasets for use by industry. Information days are frequently organised to disseminate information on the work of ECCC.

Apart from work on these European Commission supported projects, ECCC supports and organises long term testing of new materials to fill in identified gaps in European data.

The composition of ECCC and its 'Advanced Creep' TN is made up of a large industrial representation comprising alloy producers, plant manufacturers and end users, and research organisations working on their behalf. The organisations represent fossil and nuclear power generation, waste incineration, chemical and refinery industry. ECCC has the strongest industrial base of any European collaborative project with a proven track record for effective co-operation.
