Bolt Tensioners

Hydraulic Bolt Tensioners are utilized in bolting applications including pipeline flanges, heat exchangers, pressure vessels, anchor bolts and many others. There are different versions and some are designed for subsea work where others are intended for topside applications.


There are also standard and spring return varieties. However, regardless of the design, all of the tensioners work at 21750 PSI (1500 Bar). At Winshaw Hydraulic Tools, we sell, rent and repair hydraulic bolt tensioners, but we can train your personnel on their use and help in the tensioner selection process as well. In addition, we can provide the hoses, fittings and pumps which go along with the tensioners to complete the hydraulic stud tensioning system.
