Fracture Analysis

Before repairing, assess the criticality of the cracks!

 

During maintenance inspections on equipment and industrial plants, after carrying out ultrasonic, TOFD, eddy current, ACFM or phased array tests, it is necessary to carry out a criticality assessment of cracks or flaws.

 

The repair of flaws and cracks has disadvantages (such as the introduction of stresses due to welding) and should only be carried out as a last resort. In most cases, cracks can be approved using API 579 / ASME FFS-1 / BS 7910 criteria.

 

In 1994, Tresca Engenharia developed the SafeCrack software, based on the criteria of API579 / ASME FFS-1 and BS 7910. And since then it has carried out the assessment of thousands of cracks and flaws and the calculation of the remaining useful life for mechanical damage processes.

 

Tresca Engenharia also assesses thickness reduction, deformations and other non-conformities found in the inspection of equipment.

The fracture calculation and the calculation of other damage phenomena such as localized corrosion, creep and fatigue is carried out according to the English Standard BS 7910 or the American Standard API 579.
