Flame arrestors from HMA INSTRUMENTATION are used as secondary protection against explosions by preventing the transmission of flame and explosion transfer in machines, equipment and plant, containing inflammable gas or steam-air mixtures of inflammable liquids. These autonomous safety systems limit the effects of the explosions, rendering them harmless, they are intended to allow flow but prevent flame transmission.

Today’s oil, gas, petrochemical, and industrial markets demand higher safety levels as technology continues to advance and quality standards become more critical. This means improved protection for both process plants and personnel. Here the implementation of appropriate safety measures to halt flame propagation in low-pressure gas and vapour systems is of particular importance.

BS&B FlameSaf Flame Arrestors from BS&B and HMA INSTRUMENTATION are often deployed in conjunction with emergency tank vents and pressure/vacuum relief vents. This technology combination gives users peace-of-mind that internationally-recognised certification is complied with, in order to ensure the highest level of protection for a range of industries and applications.

BS&B FlameSaf Flame Arrestors from BS&B and HMA INSTRUMENTATION are based upon the technical principle of preventing flame propagation and potential explosions being transmitted through gas pipelines. Additionally, BS&B FlameSaf Flame Arresters are necessary for the protection of flammable liquid storage tanks. The flame arrester essentially reduces heat from the flame source itself, while still allowing the flow of gas and vapours under normal operating conditions.

Traditionally, applications requiring both pressures, a vacuum relief vent, and flame arrester meant that these individual components had to be bolted together, resulting in a bulky assembly. BS&B FlameSaf Flame Arrestors from BS&B and HMA INSTRUMENTATION feature a unique design of a pressure and vacuum relief vent, with an integrated flame arrester, is substantially more compact, reducing the size and weight by up to half.
