Did you know that the first torque wrench was invented by Conrad Bahr in 1918, while working for the New York City Water Department? He designed to prevent overtightening bolts on water main and steam pipe repairs underground.
Pneumatic torque wrenches are a thing of beauty when handling tough jobs, find this useful anywhere accurate torque is required on a nut and bolt, or where a stubborn nut needs to be removed.
In general, any equipment that is used to tighten high tensile bolt connections (for example, torque wrench or hydraulic tensioning devices) needs to be calibrated in strict accordance with the manufacturer instructions.
Proper torque wrench calibration can prevent disaster and ensure everything works according to plan and keep the job on schedule
Every garage, engine builder, or race team has a torque wrench, and no doubt will use it quite a bit. But when was the last time you gave more than a moments glance at your torque wrench? Without a doubt one of the most often overlooked and most used pieces of equipment in any race teams or home garage has to be their torque wrench.
A torque wrench actually is a relatively inexpensive piece of equipment when you consider how often it is used to create serious horsepower or to ensure our wheels do not come flying off driving down the road. A typical “click style” torque wrench will usually run between $100 $400 and if cared for properly can last a very long time.
Be careful to make sure you know for sure just how accurate your favorite torque wrench calibration is. Improper torque wrench calibration can have devastating effects. Any mechanic understands how crucial it is to have torque wrench calibration on point. Those who work closely with many of the top NASCAR and NHRA teams as well as numerous engine builders across the country to supply engine and driveline fasteners live by good torque wrench calibration.
There are many different varieties of tensioners, including variable, fixed, subsea, wind turbine, and pump coupling tensioners. Are you looking for a hydraulic tensioner, a hydraulic torque wrench or a nut splitter? Hydraulic tensioners are primarily used for many types of bolt and stud tensioning applications, along with turbines, wind turbines, steam turbines, heat exchangers, pipeline flanges, valves pumps, pressure and reactor vessels
Torque bleeding often results from improper torque requirements upon fastening, this is something to avoid.
Hydraulic flange spreaders are most usually the best tool to use for medium to large high pressure flanges. Proper torque wrench calibration can save your life.
