Attachments on elbows affect elbow flexibility (k) and strength (i). But the piping codes do not define adjustments to k and i (flexibility and stress intensification factors, respectively) for use in pipe flexibility and stress analysis.
Attend this webinar to learn about important considerations when modeling and evaluating these piping components and assemblies in CAESAR II.
The following poll questions will be asked:
- Does your company offer a standard approach to modeling trunnion-supported elbows?
- Do you address any change to the elbow flexibility factor when modeling an elbow attachment?
- Do you adjust elbow SIFs or set trunnion SIFs when a trunnion is attached to your elbow?
David Diehl graduated with a BSME from Lehigh University USA in 1976. Upon graduation he took a post as a technical support representative for Auton Computing in New York City. After four years David relocated to Houston, Texas providing technical support for Auton’s Dynaflex – a mainframe-based piping system analysis program. In 1986, he took a position at Intergraph CADWorx & Analysis Solutions (COADE, Inc.) introducing and selling CAESAR II – the world’s first PC-based pipe stress analysis package. While at ICAS Dave earned his Professional Engineering license and served as the product manager for CAESAR II. He currently manages ICAS training and is the lead instructor for CAESAR II and the principal author of the CAESAR II on-line training course (available at www.pipingdesignonline.com). Dave joined the B31.3 Process Piping Committee in 1999. He now serves as the Vice-Chair of that committee and a prior Chair of the B31.3 Subgroup on Design. He also served 16 years on the Board of Directors for SPED – the Society of Piping Engineers and Designers.
