How PROTEGO® helps

Since 1954, we have engineered and built   Flame Arresters Flame Arresters A flame arrester, deflagration arrester, or flame trap is a device or form of construction that will allow free passage of a gas or gaseous mixture but will interrupt or prevent the passage of flame. , Pressure and Vacuum Relief Valves, and Tank Safety Systems backed by the world’s largest sector specific R&D center, serving upstream, midstream, downstream, and LNG.

We pair application-specific engineering with certified products to mitigate explosion Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. risk, manage tank pressure Tank pressure Tank pressure is the pressure within a tank. , and handle vapors safely across terminals, pipelines, and processing facilities.
