Our hydraulic bolt stretcher can quickly and safely synchronously stretch bolts.
They can apply force to each bolt evenly and permanently. If the bolt is not properly stretched, it will not work properly. For the connection combination, accurate stretching combination is the key. Hydraulic bolt tensioner reduces this risk. Precise calculation of preload can avoid bolt damage during tension.
Hydraulic bolt stretcher is a tool for bolt disassembly and assembly. Synchronized pre-tightening, pre-tightening and disassembly of high strength bolts can be realized by using bolt stretching technology. Synchronized compression or separation of contact surfaces can be realized.
It can provide all kinds of required pressure and thrust. The tensioned bolt is subjected to pure tensile force and will not distort or damage the surface of the fastener.
It can also tighten several bolts at the same time, which greatly improves the assembly efficiency.
Hydraulic bolt stretchers are fixed and variable. They can be used in reactors, flanges, pressure vessels, compressors, turbines, pipelines, clamping connectors, underwater operations and nuclear power applications.
The built-in spring can automatically reset the piston.
Hydraulic bolt stretcher is widely used in and has strong adaptability.
