Pipe Clamps For Hazardous Areas


  For use in hazardous areas Ex zones 1 and 2 (gases, vapours, mists) as well as Ex zones 21 and 22 (dusts)
  Tested according to explosion group IIB
  Time-saving installation no need to deactivate systems/areas for welding or drilling works

So far equipotential bonding and lightning equipotential bonding of pipes in explosion-hazardous areas has been implemented by means of welded or threaded bushing connections. Using clamps was only permitted if evidence of no ignition sparking in case of lightning current loading was provided. Such proof has now been rendered for a pipe clamp by DEHN.

In compliance with and tested according to EN 50164-1 title English: Lightning Protection Components (LPC) - Part 1: Requirements for connection components in a potentially explosive atmosphere (clamps and connectors), the sample passed the test for no occurrence of ignition sparks at a lightning current loading of up to 50 kA (10/350 s). This novel, patented pipe clamp for hazardous areas not only ensures the safe electrical contact by means of two contact clips, but also the adequate mechanical fixing by an electrically insulated clamping body.

The Ex pipe clamp provides following connection possibilities:

- Round conductors made of Cu, St/tZn, Al, StSt with O8 mm or stranded copper conductors, cross section 16-35 mm2, with E-Cu crimping cable lug (DIN 46235)

- Flat copper conductors with minimum dimensions of 20x2.5 mm and a bore of O10.5 mm
