Flame arresters are used as secondary explosion prevention measures for flame transmission or explosion prevention in machinery, equipment and installations containing flammable gases or vapor mixtures containing flammable liquids. According to Directive 94/9/EC, these are protective systems that limit explosions to a non-hazardous extent.
BS&B works on a proven principle called the "flame retardant gap" in the development and design of flashback holders. This principle is achieved by means of dry flame arresters, which are normally made of metallic belt holders with defined gap widths in different configurations, depending on the process requirement. Specially trained skilled workers, together with precision machinery, ensure that the gap widths of the belt holders are of equal quality. The latest measurement techniques guarantee objective testing and documentation of these safety-relevant quantities.
Test certificates are available for all required raw materials. Compliance with 94/9/EC of our flame arresters is an EC type test certificate, e.g. Certified by DNV, IBExU, BAM, PTB.
As a certified manufacturer of pressure regulating devices, BS&B is a leader in the manufacture of flame arresters with more stringent customer requirements.
The BS&B FlameSaf quality assurance system is controlled by Det Norske Veritas (DNV), which issues certification to BS&B according to ISO 9001.
