When you use a bolt or stud as a fastener then you need to put enough force to keep the joint firm so that it works almost like a spring. In case the force applied is low or not sufficiently uniform then the joint may often fail.
In such conditions, hydraulic tensioners can provide number of advantages. With the help of hydraulic force tightening problem will become much easier and there will be no issues regarding improper tightening. This is one of the method of tightening the studs, some of the typical applications of hydraulic tensioner are as given below:
- Pressure vessels
- Valves and Pumps
- Heat Exchangers
- Steam and Gas Turbines
- Coal and Rock grinders
- Wind turbines
- Pipeline Flanges
- Diesel Engines
- Shaft couplings
- Catalyst reactor
Few advantages of using hydraulic tensioner
- Stud loading can become repeatable and accurate
When you use hydraulic based tensioner then the working of stud is based on a simple theory. This kind of tensioner consists of a certain very special type of hydraulic cylinder. The amount of pressure will depend upon the area of cylinder, which has been offered by the hydraulic pump. These are various parameters that can be accurately monitored and controlled. As a result, the tensioning of the stud can be obtained as per the exact requirements. If you want to repeat the process again then you can get same amount of force.
- Uniform stud loading
In many applications, you may need to use gaskets for loading each and every stud. Moreover, you need to do it in a proper manner. By introducing hydraulic tensioner for stud, you can obtain much better results and also you can use number of studs together. Tensioners used for these studs are so arranged that they are controlled with the help of a pump. Thus, the pressure on each stud remains almost the same when you use more hydraulic pressure. Flanges also come in uniform manner.
- You can save both your time and labor
By using few numbers of hydraulic stud tensioners, you can certainly save lots of time as they will work, simultaneously. If you compare with hydraulic torque wrenches you will find that hydraulic tensioner is much faster and therefore it will help you to save lots of time.
- Stud life will be increased
By using hydraulic tensioner, you can eliminate thread galling and seizing and thus stud life will get enhanced.
