Energas Technologies has introduced the new Protectoseal Series 26000E / 36000E bi-directional overdriven and unstable detonation arresters, aiming to allow operators to withstand both deflagration and detonation flame fronts
“The beauty of our new Series 26000E / 36000E bi-directional overdriven / unstable detonation arresters is that the flow and pressure drop performance for these units are extremely competitive compared to other manufacturers’ devices,” said Lavenda Sekwadi, process engineer at Energas.
“Protectoseal’s Series 26000E / 36000E detonation flame arresters are designed to withstand deflagrations, as well as stable detonations overdriven/ unstable detonations. These arresters are bi-directional, capable of stopping a flame or detonation approaching from either direction of a piping system,” added Sekwadi.
The Series 26000E / 36000E detonation flame arrester aims to utilise improved-flow, crimped metal flame arrester elements. The range comes with high-strength, welded housing, both hydrostatically and pneumatically tested, said Energas.
“Protectoseal’s Series 26000E / 36000E detonation arresters are suitable for short time burn when additional external safety equipment is properly used in accordance with the requirements of EN ISO 16852. The temperature probes are used to detect a burn on the flame arrester element and send a signal that will trigger emergency functions within a burning time of 50 per cent of the specified burning time,” according to the company.
Unstable detonation arresters are required for safety in piping containing flammable vapours, as encountered in vapour recovery or manifolded tank systems. A confined flame front will accelerate from the point of ignition, quickly reaching the speed of sound in the pipe run. During the unavoidable transition period from subsonic to supersonic speeds, flame front pressures and velocities are far greater than before or after the transition (an unstable detonation), explained the company.
Energas Technologies has been one of the leading suppliers of high-end and specialised equipment to the oil and gas industries in Southern Africa since 2001 and is the distributor for Mokveld in South Africa.
