Bs&b rupture disk catalog full#
BS&B has a full range of safety heads including screw type, union type, and full bolted style holders. Used in combination with the appropriate disk BS&B Safety Heads provide simple, fail-safe installation using asymmetric locating pins and J-Both to ensure correct disk orientation. Includes standard, solid metal, full opening, non-reclosing designs and composite or graphite, non-fragmenting designs for low burst pressures. Can be accompanied with a BS&B specific safety head or installed directly inline between existing flanges. Score lines can be added to the design for precise pressure control and increased capabilities. BS&B’s Sur-Saf™ system provides unmatched reversal safety ratios and damage safety ratios providing the most reliable line of rupture disks available.Īpplying load to the concave side, forward acting disks regulate burst pressures based on the tensile strength of the material. Designed primarily to meet the requirements of ASME VIII, these designs are provided with a safety head which ensure proper installation into the relief system. These discs have a 90% or greater opening ratio with a solid metal construction for optimum leak tightness. Designed for non-fragmentation upon activation, Reverse Buckling Disks can be used to isolate relief valves or as primary overpressure protection.
