Scope

This standard specifies the type, size and technical requirements for reinforcing rings used to reinforce openings in steel pressure vessel shells. This standard is used when steel pressure vessel shell openings are reinforced with reinforcing ring structures, and the following conditions should be met at the same time: a) The design pressure of the vessel is less than 6.4MPa; b) The design temperature of the vessel is not greater than 350°C; c) The vessel shell The nominal thickness at the body opening is ξn≤38mm; d) The lower limit of the standard tensile strength of the container shell steel is not greater than 540MPa; e) The thickness of the reinforcing ring should be no more than 1.5 times the nominal thickness at the shell opening. This standard is not recommended for containers made of chromium-molybdenum steel, nor is it recommended for containers containing extremely toxic and highly hazardous media. This standard does not apply to vessels subjected to fatigue loads.
