The STS Series preload cylinders in inch sizes are designed for topside applications in a wide variety of applications including pipeline flanges, heat exchangers, pressure vessels, compressor covers, boiler feed pumps, anchor bolts and more. The range consists of 26 inch options with thread sizes 3⁄4" to 4" and all models can run at an operating pressure up to 1500 bar. Each of the 6 hydraulic preload cylinder models can be operated with different thread pullers and nut washers to ensure that the largest possible range of bolt sizes can be used with the smallest possible number of hydraulic cylinders.
All Hi-Force hydraulic preload cylinders are equipped with a wear-resistant coated piston, a maximum stroke indicator, self-activating high pressure seals and dual quick-release couplings for easy connection of multiple preload cylinders and user-friendly operation/maintenance.
