At request of a client Wagenborg Foxdrill has modified a sucker rod tong (used to make/break connections in oil pump rods).

Starting point was a US built & designed tong, which in its specific type was not available with ATEX certification, required for safe use in explosive atmospheres.

The clients’ request was to make the tong compliant in such way that it could be used in a Zone 1 environment (directly above the wellhead).

After the leader of the project followed a course for explosive analyses, cooperation was started with MIBEX (explosion safety expert for product design) to create an ignition hazard assessment. Following this ‚Äčassessment several tests and modifications were carried out, including material use, anti-static features and reducing operating speeds.

After review of the technical documentation by a notified body, a declaration of conformity was issued, formally completing the project.
