CAESAR II 2018 (Version 10.00) Part 1 of 2

Image result for hexagon software

New and extended capabilities have been added to the latest version of CAESAR II, version 10.00 – 2018.
The software has been updated to B31.3-2016, EN-13480 (2016), B31.8-2016, B31.8 Ch VIII 2016.
Other piping and equipment codes support have been updated, like B31.3 Chapter IX (high pressure piping) and  Kouatsu-Gas Hoan Kyoukai KHK level II seismic analysis.

Is now possible to identify supports, by using the new support tag field in the extended Restraint auxiliary panel, where two additional restraint definitions have been added. In this way all the six degrees of freedom of a support can be described in one single panel.
A tag hanger field has been added to the Hanger input list as well.

Very interesting is the Element name or in the Piping Input Window or in the Elements list input.
You can choose to show supports and hanger tags and element name in the graphic view.
Other two fields have been added to hangers and support lists, in order to read and import data from PCF files and to export through output reports and MDB output tables.
This topic will be discussed in the second part of this article.

A number of important enanchements in Piping Input:

  • new find and replace function (in the right-click menu) added in the List dialog.
  • when a pipe element in deleted is no more necessary to reset the coordinates
  • is now possible to display the North arrow in both Classic Piping Input and Static Output Processor
  • Previous and Invert options
  • Added Mill Tolerance icon and new Mill Tolerance options
  • When load cases are deleted in the Load case editor, the remaining load cases are renumbered after a windows shows the load cases and their dependents that will be deleted or revised.

Global pressure equipment regulations and guidance

Lloyd’s Register has created a Pressure Equipment Regulation map, that covers 70 countries/areas.
By clicking on any of the coloured countries and regions is possible to know what is the “country specific regulation governing the manufacture of pressure vessels, equipment and accessories, having a high level summary and the direct links to governmental websites of countries where available.”
This is a very useful tools to reduce compliance risks and expand in new markets.
As LR writes, since “requirements for a given jurisdiction change from time to time, you should always contact the regulatory body to confirm the accuracy of the requirements summarized” on what this knowledge map.

A deep knowledge of the local pressure regulations is a time-saving key-skill to stand in piping stress analysis engineering market.
Should you find some update to the regulation indicated on the LR map, feel free to add a comment or to contact LR.

ASME B31.3 – 2012

New version of ASME B31.3 has been issued.
In this version the table of Basic Allowable Stresses (A-1) has been totally revised. It has also been added a version with metric units (Table A1-M).
Also has been added the metric unit version of Table A-2 (Design Stress Values for Bolting Materials) and of the sample calculations for Branch connections (Appendix H).
Another change of B31.3 2013 is the Appendix N about  Application of ASME B31.3 Internationally. Continua a leggere

Mill tolerance and Piping Stress Analysis

“Where does mill tolerance come from?” Does the mill tolerance affects weight, Fy and sustained stress for B31.3?”, “What should be taken as a tolerance on plate? “, “What is the significance of “-12.5% Mill Tolerance”. “What if I check “all case corroded” in Caesar?”. These are samples of questions about mill tolerance found on forums.

PCL Gold 4.01: new release of Pipe Stress FE/Pipe

New pipe stress module PCL Gold available in the latest release of FE/Pipe.
PCL Gold can be used in case of friction and other non linerarity convergence issues, to automatically run FEA at intersection, to study pipes with large D/T, in case of multiple load cases, high number of cicles, if we want to automatically run FEA at intersections, if accurate ASME B31.1 and B31.3 i-factor and k-factor has to be calculated, for  acoustically involved vibrations, glass line pipes and refractory line pipes.
