publications listed in Clause 7.1.1 for temperatures -29 ‘C (—20’F) and greater Owners, designers, fabricators, and repair organizations should carefully review the material toughness requirements on a case-by-cost basis to determine if It might be necessary to apply one or more supplementary mat eraI requirements, such as heat treatment (specifying norrnoliied material),, fine groin size, snipoct testing, and/or more restrictive chemistry requirements (e.g.. manganese-carbon ratio greater than 5.0).
2) Designers, fabricators, and repair organizations should review carbon steel toughness requirements with the
owne,-, where appropriate, before applying the impact testing exemption allowed in
a) paragraphs UG-20(f), UCS-66, and UCS-67 in Section VIII. Division 1, of the ASME Code;
b) paragraph 3.11 in Section Viii. Division 2of the ASMF’ Code; or
c) paragraph 323 of ASME 831.3.
Owners, designers, fabricators, and repair organizations may consider performing Impact testing irrespectIve of the ASME Code impact frsting exemption rules, or the use of low-temperature materials (e.g.. 5.4-350 LF2,
5.4-333 Gr. 6, SA-420 WPL6).
7.1.2
The designer of a pressure vessel that incorporates a quick-actuating closure shall take into consideration the requirements of Section VIII, Division 1, Appendix FF of the ASME Code.
7.1.3
In addition to the impact testing requirements specified In the ASME pubhcations listed in Clause 7.1.1, carbon and low alloy steel used for the construction of pressure vessels at a minimum design metal temperature below —46 ‘C (—SO’F) shall be impact tested at the minimum design metal temperature or a lower temperature, and the test results shall meet the requirements of paragraph UG 84, Section VIII, Division 1, of the ASME Code.
7.1.4
All pressure vessels designed for cyclic service and pressure vessels designed to Section VIII, Divisions 2 and 3, of the ASME Code shall comply with the following requirements:
a) In ensuring maintenance and safe operation of pressure vessels, the owner shall maintain an appropriate equipment record system containing information about and documentation of incidents affecting the safe operation of the pressure vessels. The recordkeeping media for the equipment record system shall be retrievable and legible, and the information and documentation in them shall be secured to prevent unauthorized or undocumented revisions, additions, or deletions.
b) The owner’s equipment record system shall include documentation such as the user’s design specification, manufacturer’s design report, fabrication documents, and operation monitoring results.
c) The owner shall establish pressure vessel operation guidelines for operators of the vessels, including the definition of cyclic operations and cycles monitoring, in compliance with the user’s design specifications and manufacturer’s design reports.CSA B51-2019 pdf free download.
