Subsea EziJac by Technofast have been used to speed up bolt tensioning procedures。

This is achieved by use of the unique patented Tri-Nut which passes over the thread majordiameter until seated, it then closes up onto the thread。This obviates the need for the time consuming process of screwingareaction nut down over the fullrequired threadengagement。
Because the nut is split into three sections, it is easilylockedhomeby the cam arrangement inside the cap。 This technology can reduce down time and maintenance problems andincreaseproductivity。It is user friendly, fast and accurate。 These tools are for purchase or hire and range in sizes to suit5/8” to 3-1/2”。

The Tri-Nut is opened, which allows it to pass over the bolt major diameter。 When the Jac is in position (fully contacted against the flange or loading surface), the Tri-nut is closed, engaging the thread。
After tensioning, the Tri-Nut is opened and removed over the bolt major diameter。 Spring return takes load cell back to zero stroke。

This speeds up the operation, saving vital diving time。

Applications include:

• Under water flanges
• Piping
• Petrochemical
