Hydraulic Tensioners

Because ensuring a leak-free solution is critical. It has to be Hydratight. For more than 100 years, Hydratight has provided world-class bolted joint solutions, assessing and managing joints to ensure leak-free start-ups. Today, we continue to set international standards in joint integrity—but we’re so much more than just a bolting and on-site machining company. Because even the tiniest leak can be costly and time consuming to repair, we manage every joint on a project for leak-free start-ups and production, which in turn removes the threat of environmental impact caused by unsafe joints.

Tensioning Solutions Hydratight’s extensive line of tensioners are suitable for either topside or subsea applications. Our tools are available through sales, rental, or with on-site technical support. Safe, reliable, and repeatable, the use of hydraulic tensioners offers many advantages over less accurate tightening methods: • Direct: Tension is applied directly to stretch the bolt, so no need to fight against friction or losses. • Accurate: The applied load is controlled very accurately, because it is directly proportional to the pressure applied to the tensioner. • Calculated: The load transfer...
