The analysis procedures in the Code essentially assume that the strain range in the system can be determined from an elastic analysis. That is, strains are proportional to elastically calculated stresses. The stress range is limited to less than two times the yield stress, in part to achieve this. However, in some systems, strain concentration […]

This Blog focused on a number of elements that can be used to assure projects do not result in litigation. These elements include: Developing a sound, complete scope of work Selecting a qualified contractor Using proven industry standards […]
FCC’s are complex units – and the design of their transfer lines has some unique considerations. While many of the lines are refractory lined to permit construction with carbon steel piping, some sections are hot walled, at temperatures well into the creep range, for the purpose of balancing thermal expansion or, in the case of piping […]
Cracking of REAC Duplex Stainless Steel Failures of Refinery Hydroprocessing Unit REACs made of 2205 DSS have in some cases resulted in significant plant damage and extended outages for repairs. In a few cases, header box welds have ruptured. Additionally, failures have occurred at tube-to-tubesheet welds and in REAC inlet and outlet piping made of […]
Plan the Work and Work the Plan I am confident that we can agree that it is essential for all projects to have an execution plan to be successful. We have all heard the common phrase, “Plan the Work and Work the Plan.” Many have been participants in strategy meetings discussing the most effective and […]
This blog outlines ways to think about reliability to help drive a culture of continuous improvement. It is the fourth in a series of Blogs on improving plant reliability performance through changes in culture, programs, equipment design, maintenance and operation. The principles we applied in implementing successful reliability programs in a number of operating plants […]
