Staff at PP SIMTECH have specialist knowledge and more than 25
years of hands-on experience in the application of fracture mechanics
technology to assess defect tolerance of many safety critical and
high value pressure vessels and piping. We consider this to be a
fundamental strength which supports our risk based integrity assurance
technical support services.
We also have active representation on the British Standards Institute
technical committee for fracture mechanics code BS7910.
We have used our expertise in this technology to deliver innovative
and highly cost saving solutions to a variety of cracking mechanisms
induced problems encountered in service as well as to complement
the RBI Assurance process
of detect detection criteria for NDT methods.
of decision trees for analysis of actions to be taken
detection of crack like defects.
of the significance of known defects in equipment items.
of structural integrity or safe operating limits, on a
basis for defects not acceptable to design Codes.
of defect growth rates and tolerable defect sizes provided
to derive more economic inspection intervals and reliable
in successful preparation of many technical safety cases for a
plant items on a fitness-for-service
Types of equipment items where we have carried out these assessments
include reactors, distillation columns, pressure swing absorbers,
reformer components, steam drum and superheater headers, ammonia
storage tanks, other types of pressure vessels and piping, which
have been subjected to a variety of cracking damage
Capability of PP SIMTECH in reliably matching plant users needs
is demonstrated by illustration of two case study examples.
