Online Companion Guide to the ASME Boiler and Pressure Vessel Codes: Criteria and Commentary on Select Aspects of the Boiler & Pressure Vessel Codes

ASME Press
Publication date:


Quick-actuating closures have been used on ASME pressure vessels for more than 50 years. This chapter was written because of the number of lawsuits filed against manufacturers of quick-actuating closures even though these were operated by the owners of pressure vessels for 20, even 30 and more, years without any serious accidents. This is because, in order to bring forth litigation, lawyers would skillfully take words in the ASME Boiler & Pressure Vessel Code completely out of context. Or, some attorneys for the injured party may misinterpret the Code rules to accuse the manufacturer of not having complied with the Code when the closure was made. So, based on experience, the author warns the writers of the ASME Code to assure that the rules are clear, concise, and understandable to the common man. He hopes that the rules in Section VIII, Division 1 will incorporate many of the suggestions mentioned in this chapter. To understand the current Code requirements for quick-actuating closures, the author identifies each of the changes made to the Code rules in Section VIII, Division 1, from 1952 Edition to the 2007 Edition of the ASME Code. The chapter includes an Appendix that provides guidance in the form of recommendations for the installation, operation, and maintenance of quick-actuating closures. This guidance is primarily for the use of the Owner and the User. The safety of the quick-actuating closure is the responsibility of the user. This includes the requirement for the user to provide training for all operating personnel, follow safety procedures, periodically inspect the closure, provide scheduled maintenance, and have all necessary repairs made in a timely fashion. The chapter also contains guidance for use by the designer. The chapter concludes with a list of suggested future changes in the Code for quick-actuating closures on pressure vessels.
