Our explosion venting systems only use our FM Approved explosion venting fasteners. Explosion venting fasteners is a specially designed mechanical fasteners, It is mainly used in explosion venting structures in explosive dangerous environments. Explosion venting systems generally use FM explosion venting fasteners as a means of securing the venting panels to the structure and the panels shall release at a minimum internal pressure of 20lbs/ft2 (0.96KPa) and a maximum internal pressure of 40lbs/ft2(1.92KPa) (According to FM1-44). They shall be designed to relieve at the lowest possible pressure that will provide adequate resistance to any applied wind loading to which it may be subjected.
