Components operate at high temperatures can fail due to creep, oxidation, carburization and metal dusting.

Eventual failure of the high temperature component can occur either by leakage or rupture at the operating temperature.

A failure in any plant will ultimately affects the shutdown of the plant and that leads to heavy losses.

It needs to be addressed by a methodology that will be developed and incorporated into design codes such as ASME, as well as in Fitness for-Service assessment procedures.

This is due to the complex microstructures of weldments that include base metal, heat affected zone and weld metal. The reliability of the structural assessments following the codes depends strongly on availability of reliable data required as input data.

Micro cracks during production either at the parent metal or at the weld metal can affect the service condition of the component which affects the life of the component.

So there is a need to qualitative and reliable check of the various components and its pressure parts by various non-destructive testing methods  for the successful and cost effective operation of the plant.

REMAINING LIFE CALCULATION                                                                             

 The remaining life assessment will be done using the following methods;

  • Metallographic analysis method
  • Oxide scale thickness method

Data collected from the site are compiled as per regulations and compared with the available plant history data. Based on the results available, it is compiled and compared with metallurgical analysis and oxide scale measurement. The expected life of the plant component is thereby predicted, specific points/findings, which needs an immediate attention will be notified to plant authorities.

Benefits

  • Enhance the operating life.
  • Increase safe operational reliability for extended life.
  • Quality assurance and Improve availability of the Plant.
  • Prevent the catastrophic failures of pressure Components.
  • Prevent forced outages & repairs.
  • Improve Overall efficiency.
