The first company's endorsement document was thought to be the 1929 patent certificate awarded to Robert LEHMAN for the first "flame arrester by detonation". The arrester system consisted in a round filter made of corrugated metal.
Nowadays, the company is producing special equipment in order to protect pipeline systems and flammable fluid-filled tanks from explosion and deflagration hazards. This protection equipment for tanks and pipelines against explosions comprises breathing valves, flame arresters and others.
Economy fields where such equipment can be successfully used are quite numerous and various:
chemical industry
petrochemical industry
methane-gas extraction industry
terrestrial and naval transport systems
cryogenic storage tanks
underground storage tanks for inflammable substances
