ATEX Zone Pipe Clamps for Explosive Atmospheres
Conductive, anti-spark stainless pipe clamps for ATEX zone 0/1/2 and 20/21/22 installations.
In ATEX-classified zones, a normal rubber-lined clamp is an isolated metal mass that can accumulate static charge — a potential ignition source. NIBRO ATEX-zone clamps use conductive static-dissipative liners and integrated bond straps to maintain electrical continuity with the pipe and the support structure.
ATEX zone classification refresher
• Zone 0/20: continuous explosive atmosphere — gas or dust.
• Zone 1/21: occasional, occurring in normal operation.
• Zone 2/22: rare, only in abnormal conditions.
Clamps in zone 0/1/20/21 require explicit conductive design. Zone 2/22 typically accepts standard stainless if bonded.
Conductive design features
• Static-dissipative EPDM liner (surface resistance < 10⁹ Ω).
• Internal bond strap from clamp body to pipe contact face.
• Optional external earthing lug on the mounting plate.
• Body: 316L for chemical service · 304L for grain/dust service.
• Fasteners: A4-70 with conductive nylon-free lock washers.
Typical ATEX applications
Hydrogen distribution headers · Solvent transfer lines · Methanol/ethanol pump skids · Grain elevator dust ducts · Sugar handling lines · Powder coating booths · Battery manufacturing electrolyte lines.
