Couplings in Painted / Galvanized Finishes
Most GRINNELL Grooved Couplings in painted and galvanized finishes comply to the electric conductivity according to clause 11.1.2 of EN 61537-2007. Tests were performed by TÜV Rheinland® and test reports are available upon request.
Couplings in Other Finishes
Earth bonding of the GRINNELL couplings in other finishes
(such as epoxy, Rilsan, etc...) can be made in steel pipework systems with an electrical continuity clip. This clip, manufactured from 301-grade stainless steel, is designed to ensure electrical continuity in situations of high current loading and /or corrosive environments, providing equipotential bonding of the
conductive parts.
Test pipe at TÜV Rheinland®
It is recommended that the pipework is assembled and
installed as recommended and that the pipework is bonded
to the electrical earth and tested in accordance with the I.E.E. regulations for bonding (earthing). Installation should be regularly checked for equipotential bonding (earthing) in case of accidental damage or unauthorized pipework modifications. Following any future modification, electrical continuity clips must be used and the installation re-tested for equipotential bonding.
