Some Definitions in Nuts and Bolts

Many industries, from energy to railroads to construction, need outstanding equipment, from hydraulic bolt tensioners to pneumatic hydraulic pumps and electric torque wrenches. To the unfamiliar, these tools create confusion. One may be tempted to throw in the towel when he hears the words hydraulic bolt tensioner. Below are some basic definitions.

Nuts and bolts, used in construction and other applications, are what hold structures together. These nuts and bolts can be found in wind turbines, which convert kinetic wind energy into mechanical energy. The oil and gas industry use hydraulic nuts, which have their own internal hydraulic jack. High tensile bolts are used mostly in shipyards, mainly on mast, jib and slew ring bearings on crane joints. The railroad industry often encounters these nuts being loosened, a phenomenon known as torque bleeding. All of these problems can be fixed with hydraulic bolt tensioner.

Finally, there are hydraulic flange spreaders that do the opposite of hydraulic bolt tensioner. These flange spreaders, while expensive, are more user friendly than traditional flange wedges and banana wedges, and can greatly reduce the chances of a flange dislodging. These are only some of the tools used in the nuts and bolts industry.
