PRESSURE & VACUUM RELIEF VENTS
Pressure and vacuum conservation vents are employed where it is necessary or desirable to reduce evaporation of tank contents to the atmosphere. These vents are used for liquid storage applications in the chemical, petroleum, refining, renewable fuels, pulp and paper and power generation industries. Protectoseal vents feature a patented FEP film diaphragm and a low-leak pallet design and all vents are leak tested prior to despatch from the factory. Conforms to European ATEX Directive 94/9/EC and available in various configurations, materials and sizes. Clamp-on steam jackets are also available for standard vents.
EMERGENCY PRESSURE RELIEF VENTS
Emergency relief vents are used on tanks and provide a means of venting under extreme cases like tank exposure to fire. Venting requirements for fire far exceed the normal venting requirements. Conforms to European ATEX Directive 94/9/EC and available in various configurations, materials and sizes.
DEFLAGRATION & DETONATION ARRESTERS
Protectoseal deflagration and detonation arresters can provide an effective means against flame propagation into storage tanks and inside pipelines containing hazardous and flammable vapours, if applied correctly. The Protectoseal range includes end-of-line deflagration arresters through to unstable detonation arresters suitable for short-time burning. Arresters can be supplied in compliance with the stringent USCG specification or to ISO 16852.
- Petroleum storage tanks
- Vapour recovery units
- Flammable liquid loading terminals and gantries
- Near other sources of ignition (example blowers)
TANK BLANKETING VALVES
Tank blanketing valves provide an effective means of preventing and controlling explosions in flammable liquid storage tanks. Blanketing valves introduce an inert gas like nitrogen into the tank that forms an inert blanket above the tank contents to prevent explosive mixtures or to prevent contamination of the stored product. Blanketing valves are used on tanks with flammable or high purity liquids. Conforms to European ATEX Directive 94/9/EC and available with various options.
