There are a variety of different tools related to bolt tightening, including a hydraulic tensioner, a nut splitter, and a A hydraulic flange, among others. A hydraulic flange spreader is a type of mechanical spreader that spreads two materials apart so that gaskets can be changed.
Heavy industrial bolting tools, such as a hydraulic flange spreader, are important in a variety of different industries. The shipyard industry has high, specific tensioning demands, which means that reliable and durable tools are absolutely essential. Torque bleeding, which is an undesirable loosening of the nut from a bolt connected assembly, is a common occurrence in the railroad industry. They are also used in wind turbines; a wind turbine is a device that converts kinetic wind energy into mechanical energy. They are also used in mining, construction, and power plants, among many other places. Mechanical tools always have to be broken in prior to calibration, especially in the case of hydraulic torque wrenches, where both mechanical and hydraulic systems work together. These tools are also essential to maintain industrial bolts and replace them when necessary. Industrial bolt deterioration can be a serious problem, particularly in areas that are typically wet or damp.
