BS&B
Rupture disks, buckling pin relief valves, explosion vents and flame arresters.
BS&B Safety Systems designs and manufactures pressure relief and explosion protection equipment: rupture disks and holders, buckling pin relief valves, safety relief valves, explosion vents, explosion suppression and isolation systems, and flame arresters.
What Ronsor supplies
- Relief valves: buckling pin relief valves, which open fully at a set pressure and are reset by replacing the pin: the in-line BPRV, the angle-pattern BPCV, the API-sized BPAV and pilot valves. Also Model 51 and Model 64 spring-loaded safety relief valves.
- Explosion protection: explosion vents, IQR flameless venting, explosion suppression, chemical isolation and flame arresters.
Where BS&B equipment is used
Our application pages show BS&B products on flare systems, silos, dust collectors and powder handling, containerised battery energy storage, storage tanks and loading and distillation columns and process vessels.
Built to order
Relief and explosion protection devices are sized and built to order for each duty: set or burst pressure, temperature, relieving capacity, materials and connections. We help size and specify BS&B devices for new plant and for replacing existing relief devices like for like.
