Must Galvanized Steel Pipe Be Used in Explosion-Proof Areas

Usage is essential. The Industrial and Civil Electrical Distribution Design Manual (3rd Edition) on page 489 specifies: In environments with explosive dust, the employment of insulated wires or plastic conduits for exposed installation is strictly forbidden.

The recommended conduits are galvanized steel pipes, typically used in low-pressure fluid transport. These pipes must adhere to explosion-proof criteria, usually necessitating a minimum wall thickness of 2mm.
