IIS SERVICE is committed to design critical repairing operations such as removal and repairing of defects detected during periodic inspections, replacement of components, repairing on in-service equipment. Such a kind of intervention is crucial where the repair is deemed necessary and the component or the pressure equipment are installed within continuous process plant and, therefore, with short time for intervention or with the need of ensuring the equipment availability for operations.

The IIS Group can support the User for pressure equipment which have to be subjected to important modifications that change their original design characteristics.

In all these cases, the IIS Group is able to perform:

  • Design of repairing / modification in compliance with ISPESL, ASME B&PV Code, EN 13445 according to national decree D.M. 01/12/2004 No.329;
  • Temporary repair design in compliance with ASME PCC-2;
  • Fulfillments with the national law requirements for the seismic action (NTC 2008 - D.M. 14/01/2008);
  • Evaluation of the component resistance during provision of repair according to API 579-1 (repairs under applied loads)

The IIS Group can provide in-field complete assistance for the supervision of the provisional works setting, for preparation and repair execution and for the final NDTs.

Furthermore, the IIS Group is able to provide overall assistance in Italy for the fulfillments of the repair according to the D.M. 01/12/2004 No.329 or the CE marking of the pressure equipment, in case of important modifications.
