Hydraulic bolt tensioning is now the preferred method of bolt tightening to achieve the high levels of first-time, leak-free joint integrity demanded by the industry.

Two years of design, development and field testing by Titan Technologies Inc. have significantly improved hydraulic bolt tensioner performance with a new tool sealing system that minimizes effort to retract the piston between cycles and eliminates oil leakage past the seal. Typically, tensioners that were easy to retract leaked. Tensioners that didn’t leak were difficult to manually retract. The new Titan seal achieves a balance of physical properties to achieve easy retraction without leakage.

This is no small achievement; Titans tools operate at pressures up to 2,500 bar (36,750 psi).
With no leakage the tools provide a consistently more accurate and uniform operating pressure. This translates in to faster performance and less downtime with more accurate and uniform bolt loads being achieved.

Hydraulic bolt tensioner tools are commonly used in significant numbers; therefore, time and cost savings achieved through easy piston retraction are impressive. When combined with the smaller dimensions of the Titan tools, a less costly solution is offered than tools fitted with mechanical retraction mechanisms. The whole bolt tensioning procedure can now be carried out in significantly less time and with less material cost, all the while achieving the most accurate and uniform bolt loads possible.
