SEEIssues
An explosive atmosphere can occur when flammable gases, mist, vapors or dust are mixed with air. When it is under atmospheric conditions there is a risk of explosion. An explosive environment includes anywhere that liquid fuels, flammable gases and explosives are stored or used.
Most explosions are initiated by a spark. Electrical equipment in gaseous environments can create a spark. As well as, wherever electric currents meet air, like a broken circuit.
But, electrical equipment is not the only thing that can cause an explosion. Built up static electricity can create a spark when it is discharged and metallic surfaces hitting each other.
There are several regulations covering potentially explosive atmospheres. The European standard is ATEX.
A gas leak is a leak of natural gas or other gaseous product from a pipeline or other containment into an area where it should not be present. It can be a very dangerous situation. because of the high risk of explosion if a flammable gas is exposed to a flame or spark.
To properly isolate some ventilation network parts from others or from the outside, closed dampers must have a low leakage rate.
In case of a duct network going through a wall, a fire damper must be installed in order to preserve the fire rating of this wall.
In the Oil and Gas market, resistance to corrosion is essential.
There are several different types of causes for corrosion, but the three major concerns for offshore or coastal equipment is aqueous corrosion, atmospheric corrosion and galvanic corrosion.
Aqueous corrosion occurs when metals come in contact with sea water.
Atmospheric corrosion occurs when metals that are on or near coast lines are exposed to hot or humid conditions combined with salt air.
Galvanic corrosion occurs when two different metals are in direct contact with one another. It is aggravated in a corrosive environment.
