DB61/T 1087-2017 DB61/T 1087-2017 Welding insulation cylinder regular inspection and evaluation
Basic Information
Scope
This standard specifies the terms and definitions, inspection agencies and inspectors, inspection cycles, inspection preparations, regular inspections and evaluations, assembly and degreasing of accessories, and post-inspection work for in-use welded insulated gas cylinders (hereinafter referred to as gas cylinders). This standard applies to vertical and horizontal gas cylinders that are used in normal ambient temperatures (–40°C to 60°C), store low-temperature liquids such as liquid oxygen, liquid nitrogen, liquid argon, and liquefied natural gas, have a design temperature of not less than –196°C, a nominal volume of 10L to 500L, and a nominal working pressure of 0.2MPa to 3.5MPa that can be refilled repeatedly. Gas cylinders with a nominal volume greater than 500L may refer to this standard for implementation.
