Process equipment that holds pressure must be protected against overpressure, and Roben Manufacturing integrates the safety equipment that provides that protection into the systems we build. Relief valves, rupture discs, and their connections are designed into the vessels and piping so the equipment is protected to code and personnel are kept safe.
Overpressure protection is not optional — it is a code requirement and a fundamental safety obligation. We design the relief connections and integrate the safety devices as part of our complete-system projects so that protection is built in, not bolted on as an afterthought.
Overpressure Protection Built Into the System
Every pressure vessel must be protected against exceeding its maximum allowable working pressure, and the code requires pressure-relief devices sized for the worst-case overpressure scenario. We design the relief connections — the nozzles and piping that carry relieving flow — into the vessels and integrate relief valves, rupture discs, or combinations of the two as the service requires.
Sizing the relief path correctly is essential: an undersized relief device cannot protect the vessel, while the relief piping must carry the relieving flow without excessive back pressure. We design the relief nozzles and connections to suit the selected devices and the relieving conditions, coordinating with the overall vessel design.
Rupture discs, relief valves, and other safety devices each have their place. Relief valves reclose after relieving, rupture discs provide fast, full-bore relief and isolation from the process, and the two are sometimes combined. We integrate the appropriate devices and their connections so the protection scheme matches the hazard.
By designing safety equipment into the system from the start, we ensure the relief connections are properly located, sized, and reinforced as part of the vessel's code construction. The integrated system arrives with its overpressure protection in place and documented, ready for the safe operation the code and good practice demand.
