Piping Methods for Explosion-proof Distribution Boxes
The following are the specifications for the inlet and outlet lines of explosion-proof distribution boxes: Wiring methods Generally, explosion-proof steel pipe wiring and cable wiring are used. Unlike standard distribution boxes that could become shrapnel shards in. The 'Ex d' protection method, today indicated as 'Ex db', is based on a simple theoretical concept: the containment by means of a robust casing and the non-propagation of the flame (flameproof enclosure). This protection method, in addition to being one of the first to be created in a historical. 1 The requirements for laying explosion-proof pipes are higher than those for laying ordinary open pipes. Need to use thick-walled pipe (galvanized water pipe), each connection also has special requirements. 2 Pipes and pipes need to be connected with junction boxes and switches using threaded. 1. 2 Plastic-Coated Rigid Steel Conduit 2.
