New Joint Industry Project: Fatigue Evaluation

Project Omega
A study by MPC of available methods for remaining life assessment methods for pressure vessels and piping in creep service.
FFS
A study by MPC for determining Fitness-For-Service against a broad range failure modes for process equipment. The findings and data gathered from this group were adopted by API and eventually ASME as the basis for a global standard on procedures and relevant data, API 579-1/ASME FFS-1.
HEP
A series of failures of welded high-temperature steam lines at electric utility plants led to a comprehensive study of failure modes and preventative measures called HEP.
Residual Stress
Residual stresses associated with welds must be included in designing for fracture-safe and cyclic service. PVRC organized a major group sponsored program to validate methods for calculating residual stresses for a variety of materials and joint configurations.
HTHA
In light of continuing problems with low-alloy steels in high-temperature, high-pressure hydrogen (HTHA), API sought an assessment and explanation of the guidance offered in API 941, the “Nelson Curves.” A contract was awarded to MPC by API to review available data and provide an assessment of the appropriateness of the guidance in the document.
HPV Prevent
After fabrication of many hundreds of heavy wall pressure vessels and many years of successful service involving the MPC developed 2 1/4 Cr-1 Mo-0 25 V (22V) steel. Some fabricators encountered some incidents of stress relief cracking. MPC initiated a new group sponsored program (HPV.PREVENT-) to address that issue and other matters of interest to owners and designers.
