All,

I just found out that the 2013 Edition of the ASME Code is due to hit the streets in early July. Section I will include the modernized Part PR and supporting mandatory and nonmandatory appendices.

Key changes include:

Part PR, Requirements for Boilers Fabricated by Rivets; Mandatory Appendix V, Additional Rules for Boilers Fabricated by Riveting; including Nonmandatory Appendices A-1 through A-6, Efficiency of Riveted Joints; and Nonmandatory Appendix A-75, Computations of Typical Nozzle Fittings Attached by Rivets.
Mandatory appendix added to address establishing governing Code edition and addenda for new construction and for parts. Manufacturer's Data Reports are revised to provide for reporting the governing edition and addenda.
Par. PEB-8.3 allowing the use of the rules in the new Section VIII Appendix 41 to be used in the design of Electric Immersion Heater Element Support Plates for Section I applications.
Addition of 1-1/4 NPS, 1-1/2 NPS, 2-1/2 NPS values to the table in PG-39.5.2.
Revision to PW-39, P-No. 3 to impose the carbon content limitation on pressure parts.
Addition of SA/GB 713 Grade Q345R material for Section I application up to 800°F(427°C).
Addition of SA-350 to PG-9.1.
New paragraph PG-60.1.2.1 on requirements for independent remote water level indicators.
