Continuous vibration combined with limited inspection access increases the risk of joints loosening, which can lead to system failure or mission loss. Nord-Lock® wedge-locking washers secure the joint and maintain clamp load under dynamic conditions.

Infrequent inspection makes it difficult to detect preload loss before it impacts performance. Nord-Lock® wedge-locking technology maintains bolt tension over time, ensuring long-term reliability without frequent maintenance.

Ensure long-term reliability

Severe vibration and thermal cycling can cause joints to lose preload, leading to instability and reduced performance. Nord-Lock® washers maintain tension under dynamic conditions, ensuring consistent joint performance.

Harsh subsea environments expose joints to vibration, dynamic loads, and corrosion, while limited access increases the risk of undetected preload loss. Superbolt® tensioners deliver accurate preload and maintain performance in demanding marine conditions.
