In-service inspection services from TWI
17/11/2010
In general terms, inspection may be applied to three main sectors of industry: manufacturing, fabrication and in-service.The manufacturing and fabrication sectors have developed inspection regimes specific to their products. These products are, in many ways, repetitive and predictable and inspection procedures have been proven to be effective when applied by competent inspection personnel.

In-service inspection has not been subject to the same level of development and scrutiny. With ageing assets and capital investment at a premium, it is necessary to try and develop non-invasive inspection techniques to locate and quantify failure mechanisms at an early stage in order to manage and control the possible interruption to production and possibly safety and revenue.By identifying the defined possible failure modes and mechanisms in a timely manner, it is then possible to re-schedule planned maintenance shutdown of plant to accommodate repair and, if necessary, replacement of components.
TWI recognises the importance of this sector of industry and has the necessary knowledge, resources and experience to assist in the management, control and development of relev
