Certain Joint Configurations for the Attachment of Welded Unstayed Flat Heads

October 24, 2018 By Michael Rodgers

FEA Joint Heads

Finite Element Analysis (FEA) is used to investigate reasons why ASME VIII-1, FIG.UW-13.2, does not permit certain joint configurations for the attachment of welded unstayed flat heads:  Joint Orientation: The eccentrically attached weld allows the joint to open under pressure.  Fatigue Life: The peak stress created at the weld root limits the fatigue life. Weld size: The weld size is insufficient to satisfy the Code’s geometric requirements  To open sample discussion

Tri-Clamp Sanitary Fitting

October 24, 2018 By Michael Rodgers

Tri-Clamp

This Tri-clamp connection is designed to comply with ASME B31.3-2008. It is an unlisted component because of its shape, hence the ASME VIII-1 Appendix-24 (24-1(b)) cannot be used to validate it. Two options remain for determining the MAWP:1. A burst test per UG-101(m)2. Finite Element Analysis (FEA) per ASME VIII-2, Part 5 The Tri-Clamp can be qualified using Option 2 under ASME B31.3 304.7.2(d). Allowable stress should be taken from

What is FEA?

October 24, 2018 By Michael Rodgers

What is Finite Element Analysis (FEA)? Finite Element Analysis (FEA) is used to solve engineering problems that are too complex to be handled using the traditional mathematically closed form solutions. According to my course notes from university: “the finite element method is a numerical method used to find an approximate solution for such complicated problems which involve irregular domains and difficult boundary and load conditions.” In broad terms, a static
