Fixed Stud Tensioners

Hydraulics Technology Inc. provides a wide range of fixed stud tensioners. For tightening bolted connections, fixed hydraulic stud tensioning is the ideal method to choose. Hydraulic stud tensioning eliminates inaccuracies and helps achieve correct bolt loading in critical connections.

HTI’s standard hydraulic tensioners are designed to fit most ANSI and API flanged connections. With HTI hydraulic tensioners, the stud can be exactly tensioned to the required bolt load.

Stud tensioning is the optimum method used to achieve proper bolt loading. Hydraulics Technology Inc has over twenty years of experience designing engineered solutions to your toughest bolt tensioning problems.

How The Fixed Model Stud Tensioner Works

The operator selects the Tensioner for the stud and nut size to be tensioned. After placing the Bridge and Nut Rotating Socket over the nut, the operator threads the Load Cell Housing onto the stud. He then connects the Stud Tensioner to the Hydraulic Pump, using Hydraulic Hoses with Quick-Disconnect (QD) fittings. The Hydraulic Pump supplies high-pressure hydraulic oil to the Tensioner Load Cell, producing an accurate axial tension that stretches the stud. When the pump reaches a pre-set pressure, the operator uses a small bar to tighten the nut by hand. He then removes the Stud Tensioner and the process is completed.

We also provide Variable Stud Tensioners and hydraulic nuts and pumps. Contact HTI today! Let us assist you with your hydraulic tensioner requirements, industries include Cell Tower Hydraulic Tensioning.
