Hydraulic Bolt Tensioners: Types, Applications and Essential Factors
Hydraulic bolt tensioners are crucial tools for industrial applications seeking out for accuracy and consistency. These instruments utilize hydraulic pressure to load a bolt in a controlled manner and provide the necessary clamping force. This process is more precise than traditional methods of tightening bolts based on torquing such as manual fastening. Tritorc is a growing leader in bolting solutions, offering several kinds of hydraulic bolt tensioners to diverse industries. In this blog, we will be discussing the various types of hydraulic bolt tensioners produced by Tritorc, their uses and consideration while choosing the right tensioner for a project.
What are Hydraulic Bolt Tensioners?
Hydraulic Bolt tensioners are the tools that utilizes hydrostatic stress on a threaded stud by torquing the nut against predetermined load. This guarantees preciseness and accuracy during tightening which is crucial for maintaining joint integrity at varied operational conditions without relaxation of bolts. They are highly applicable in high stress zones like oil and gas fields, power plants or heavy machinery sectors.
Types of Hydraulic Bolt Tensioners
High tensioning force applied on the bolts are the reason multi-stage tensioners are designed. Their ability to produce the desired load through numerous hydraulic phases makes them perfect for heavy-duty applications involving very large bolts.
High Load Capacity: Able to exert a considerable amount of force on big bolts.
Precision: Assures consistent and precise tensioning at various phases.
Durability: Capable of withstanding hard industrial settings.
Applications:
