Using tension from a bolt, you can secure anything. Safely maintaining the correct mechanical tension requires a tension within around 80% of the bolt’s optimum tensile strength. To tighten a bolt, a machine is used to stretch the stud bolt. When a nut is screwed onto a bolt, the material is stretched. When the nut is tightened, the head of the bolt’s metal springs back to its pre-stretching form, releasing the stress. Read below to learn more about the hydraulic bolt tensioner.
The term “spring tension” describes this action. The required force is generated when the bolt relaxes to its original position and tightens on the nut. The program’s connection was established to ensure reliability throughout service. When the nut is tightened, the stud bolt is stretched using a hydraulic bolt tensioner to the correct preload.
Industrial bolts may last forever if they are installed correctly and serviced periodically. The correct amount of stress on the bolts is achieved and kept constant with the help of a bolt-tensioner system.
What is the value of Hydraulic Bolt and Stud Tensioning Systems?
- Loading Studs Accurately and Consistently:
Hydraulic studs and bolt tensioners and tensioners are easy to use and understand in principle. A hydraulic stud tensioner is a hydraulic cylinder designed for a specific function. Its ability to apply tension to a stud is proportional to the hydraulic cylinder’s cross-sectional area and the Pump’s hydraulic pressure output.
You have tight control over these factors, allowing precise stud tensioning. Therefore, hydraulic tensioners will make it simple and repetitive to load and tighten studs properly.
- Evenly Loaded Studs:
When using gaskets, it is crucial to load each stud evenly. The expert hydraulic bolt tensioner manufacturers recommend Multiple Hydraulic Stud Tensioners for situations requiring more than one stud. The Pump and each of these Hydraulic Tensioners are linked inside. When the hydraulic pressure increases, the flange comes together uniformly and simultaneously due to the uniform tension across every stud.
- Usability and security:
Power to weight is very high in hydraulic studs and bolt tensioners. They are significantly more portable, lightweight, and simple to use than torque instruments. Most software now requires a single operator. The operator handles the load cell, pulley bar, and bridge of the hydraulic tensioner.
Compared to a hydraulic wrench and socket of the same stud size and tightening capability, the weight of these components is often far lower.
Instead of using a slug wrench or a bolt warmer, you may use a silent, safe hydraulic stud and bolt tensioner. Hydraulic pumps run by air or operated manually are safe from explosions.
- Enhanced Stud Survival Rate:
When using hydraulic stud tensioning, thread galling, and seizing are avoided. Galling is prevented on the threads and nut interfaces while employing hydraulic tensioners.
Summary:
It’s hard to conceive that the stud or bolt in your hand can also function as a spring, yet that’s precisely what it does. In reality, bolts do exactly that in a connection. They must be stretched during assembly to a sufficient degree to ensure that the joint remains securely fastened together once it is put into operation. The joint might fail when the load in the studs is too low, too high, or inconsistent from stud to stud.
The quick and easy solution to this issue is to use tensioners or a hydraulic nut-tightening system. The enormous expenditures caused by improperly tightened studs may be kept in check by paying attention to the tightening process.
