The UCS-66 rules of the ASME Code apply to new construction. But what if the vessels in your plant were fabricated before the brittle fracture rules of UCS-66 were in effect and you want to make sure your operating procedures limit the risk of brittle fracture? This is where our API 579-1/ASME FFS-1 Fitness-For-Service software, INSPECT, comes into the picture. INSPECT includes API 579-1 Part 3 brittle fracture assessments and, starting with Build 7900, the ability to produce minimum allowable temperature versus pressure (MAT) charts. The INSPECT MAT feature automatically runs Part 3 assessments over a range of pressures to simplify and speed up the creation of pressure vessel MAT integrity operating windows.
In addition, satisfying the brittle fracture requirements of API 579-1 Part 3 is mandatory when performing Fitness-For-Service assessments on most flaw types including local metal loss, pitting, cracks, dents and gouges.
