  • EDSE Technology

    The Electric Discharge Sampling Equipment (EDSE) was developed by our UK based partner 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.…

  • Obikou

    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….

The portable I-SFM (Integrity-Scanning Force Microscope) has been developed for early stage damage detection such as creep cavitation (especially in P91 & P92 steels) which will not be found using traditional replication techniques.

Atomic, or Scanning Force Microscopy, is a surface examination technique using a mechanical tip in contact with a surface. The tip is attracted or deflected by surface features through inter atomic forces.

Plant engineers will no longer be required to machine out small pieces of material from thick section components for study in the lab under an SEM (Scanning Electron Microscope) – I-SFM is portable, so it is taken and used directly on components on-site during outages. I-SFM connects to a laptop while operating so that the information it detects is instantly available and can be recorded and manipulated by the user on-site, or can be instantaneously sent in electronic format for analysis.

The Problem

A number of welded P91 components have experienced premature failure, some after only 20,000 hours or less.Replication and associated SEM examination does not show significant cavitation until late in life (above 70% of life), and spheroidisation does not occur in martensitic steels.

New NDE techniques needed to be developed to predict in-service component deterioration at a reasonably early stage in life.

The Solution

The development and use of a portable Scanning Force Microscope (SFM) for detection and study of early stage creep cavitation and damage at the I-SFM truly represents the cutting edge in damage detection.
