De-coupling SRD type
A risk of explosion widely occurs in almost every branch of industry, transportation and explosive dust or liquids storage. Lots of preventing methods are known, many designing solutions may be applied, either. Explosion protective systems distinguish on following classes: venting, suppression and insulation. Venting and suppression of explosion are applied for appliances like closed solids, so as to protect them against overpressure.
The aim of explosion insulation systems is to defend against the fire and pressure expansion. Chemical decoupling is a solution for fire (caused by explosion) spreading prevention in connected pipelines, as chemical powder barrier is created. The system comprises of adequate detector and a bottle filled with powder under a pressure of nitrogen.
FIKE’s decoupling systems are placed at pipeline’s junction. Due to appliance insulation, following steps are taken: detection, initiation and insulation. All these aspects influences the effectiveness of protective system. Providing suppressing powder, after the detection, is of order of milliseconds. It’s a crucial moment. Also a powder selection is of high importance, considering a speed of fire and process parameters.
