API 579 Part 6 Pitting Assessments Using INSPECT

INSPECT performs Part 6 level 1, 2 and 3 pitting assessments and generates detailed API 579 reports with one button click.  Assessments can be performed for both localized and widespread pitting.  In addition, pitting damage may be located internally, externally, or on both sides of the vessel.  Interactions between pitted regions and local thin areas are automatically detected and addressed as well.  Other Part 6 highlights include:

  • Pitting flaws are displayed to scale on the INSPECT 3D model.

  • Images may be added to the Level 1 pitting report to satisfy the Part 6 requirement for a scaled photo or rubbing of the surface of the damage.

  • Pitting measurements may be entered manually or copied and pasted from a spreadsheet.

  • Individual joint efficiencies may be defined for each pitted area.

  • Calculations using ASME Section VIII Division 1 or Division 2 equations can be performed.

  • Supplemental load calculations are provided.  INSPECT calculates Part 6 supplemental loads automatically, with vessel geometry, vertical loads, lateral forces, wind and seismic loads taken into consideration.  Supplemental loads may also be manually entered.

  • Tensile and compressive longitudinal stresses are considered for all applicable load cases.  The allowable compressive stress is calculated using the methodology in API 579-1 Annex A.

Increase Your Capabilities With INSPECT

API 579 Part 3 Ensure your operating procedures limit the risk of brittle fracture by automatically running Part 3 assessments. API 579 Part 4 & 5 Perform general and local metal loss assessments and quickly generate detailed reports. API 579 Part 6 INSPECT performs level 1, 2 and 3 pitting assessments and generates detailed API 579 reports with a click of a button. API 579 Part 7 Perform Level 1 and 2 assessments from Hydrogen Induced Cracking (HIC) and Hydrogen Blister damage. API 579 Part 8 Ensure that vessels subject to external pressure are within the allowed roundness tolerance with out-of-roundness assessments. API 579 Part 9 Level 1 and 2 assessments quickly determine which crack-like flaws can be safely left in service and which require more investigation. API 579 Part 10 Perform creep damage assessments by recording equipment operating histories and calculations. API 579 Part 11 Perform fire damage assessments and document conclusions in a consistent series of data entries and reports. API 579 Part 12 Perform Part 12 assessments and generate detailed API 579 reports. Level 1 and 2 dent, gouge and dent-gouge combinations are available. API 579 Part 13 Model laminations and provide rapid results so you can make the necessary mediation decisions with confidence API 579 Part 14 INSPECT’s fatigue assessment scans the vessel for other flaw types and allows the user to adjust the “remaining strength factor” (RSF) as required by API 579. API 510 Address in-service activities such as inspection, remaining life determination and repair. API 570 3D inspection data management and calculations simplify compliance with the requirements of the API-570 Code. API 653 Track tank thickness inspection measurements and provide calculation reports. Gage Integration Set up and retrieve inspection grids from thickness gages fast and easy. OSHA 1910 Meet the Mechanical Integrity requirements of OSHA1910.119 (j) and EPA Title 40 part 68.73. Undocumented Vessels Pressure Vessel Inspection Code requires owners to maintain permanent, progressive records as listed in API 510 Section 7.8 The INSPECT IDMS Show condition monitoring locations (CML’s) and API 579-1 flaws directly on pressure equipment models. Auto-Refrigeration MAT curves are employed to determine which process conditions put equipment at risk of failure by brittle fracture. Old ASME® Codes Supported Increase vessel life automatically by using the higher allowable stresses per NBIC Section 3.4.
