Industries & Applications

Mineral

MineralMineral extraction and processing environments need fluid sealing products and other components that can safely withstand the harshest levels of abrasion and aggressive chemical action.

At James Walker, we have well proven ranges of products especially for these areas of operation.


Bolting Technology

90% of all bolted joint failures can be attributed to low tension on installation. Achieving and maintaining the correct tension will eliminate failures from fatigue, vibration loosening, structural slip and pressure containment. RotaBolt® technology is the science of measurement, t accurately measures tension so that it can be correctly achieved, maintained and monitored. With the right joint design, component quality and installed tension, integrity of the bolted joint is assured.
