Brown</p><p>Number of Pages:</p><p>34</p><p>Abstract:</p><p>This WRC Bulletin chronicles the development of the methods detailed in ASME PCC-1-2010 Appendix O </p><p>Assembly Bolt Stress Determination. It includes all the information necessary to enable engineers concerned </p><p>with sealing reliability to reproduce and build on the work that went into that part of PCC-1. The intent is not </p><p>to reproduce the method or to include all details of the development of the method. Instead it is to provide </p><p>references to the documents written during the development of the method and to provide additional details to </p><p>assist in the understanding and extension of the method in the future. This WRC Bulletin provides references to </p><p>the historical development articles, an explanation of the basis for the method, a step-by-step guide as to how </p><p>to apply the ASME code equations to determine flange limits, and a commentary on the Elastic-Plastic Finite </p><p>Element Analysis (FEA) methods presented therein.</p><p>The information presented will assist in developing general limits for acceptable bolt stresses that can be </p><p>applied to flanged joints without damaging them. This is the case for both standard piping flanges and custom </p><p>pressure vessel and heat exchanger flanges. By incorporating the equations outlined in this document, not only </p><p>can the correct assembly bolt load be determined, but the joint can be designed such that it is not possible to </p><p>over-stress the gasket or flanges. This approach vastly improves the practicality and reliability of the joint. By </p><p>strictly following these procedures it will not be possible to permanently damage the joint during assembly or </p><p>operation. The method presented also, enables determining which of a joints components are limiting. Absent </p><p>that knowledge it is not possible to correct the root causes of joint leakage. Finally, the document provides </p><p>important insight into gasket relaxation factors.</p><p>$75.00</p><p>Page 2 of 3WRC 538 | Welding Research Council</p><p>7/2/2014https://forengineers.org/bulletin/wrc-538</p></li><li><p>Login Privacy Policy Terms and Conditions Frequently Asked Questions</p><p>Copyright 2014 Welding Research Council, Inc. </p><p>Add to cart</p><p>Page 3 of 3WRC 538 | Welding Research Council</p><p>7/2/2014https://forengineers.org/bulletin/wrc-538</p></li></ul>
