There are many tools and amidst them, one is bolt tensioner. It is an annular jack that simply fits over the fastener to get tightened. The tensioner simply fits over the bolt and nut that demand tightening. The tensioner pushes against the bolted joint and even pulls on the end of the bolt, to promise proper engagement of the puller, a least of one bolt dia length of thread above the nut must be maintained.
Well, as the force generated by the bolt tensioner is directly applied to the end of the overall bolt, load equivalent tension produced by the jack is to simply shank of the bolt. With the jack in the realm of tensioner applying tension, it makes turning the nut with zero torque absolutely convenient.
Flexible hoses or pipes with self-sealing quick connect couplings get connected to multiple bolt type of tensioners to form a hydraulic ring main. The bolt type of tensioners and ring man are quite pressurized by three ways known as air driven, even electric driven or hand pump. These are the off-shelf bolt type of tensioners that get designed to work on standard flanges such as API, ANSI, etc. To offer utmost convenience, one can get them in sets. This enables the operator to tension nearby sized bolts by making use of the same load cell by just change of puller.
The designs
All bolt types of tensioners are properly designed to tension ANSI type flanges. In some of the cases, these tensioners are customized and specifically designed to cater non-standard flanges; these customized bolt tensioners can simply fit into restricted spaces or even work at a higher pressure to offer more load, since they have a tinier dia in comparison.
To offer the same or even more load in which radical space is restricted, bolt type of tensioners are constructed with puller threads that are integral with the load cell to diminish the dia of the tensioners. The only difficulty of these tensioners is that it is somewhat restricted to work on a specific bolt dia and thread pitch. For your information, special sort of need for such types of customized tensioners can be found in industries such as infrastructure and wind, where the need of bolt load is higher and even need a special multistage tensioners to accomplish the desired output. Since these tensioners have a tiny dia and are somewhat taller in height, the bolt protrusion above the nut requires to be controlled.
However, no matter how effective, efficient and productive a tensioner maybe, if it is not made up of a good quality, it may underperform only. So, you have to be confident that you use only the best and most effective, quality tensioners. Don’t compromise with the quality or it may be harmful for your operations, procedures and tasks.
Conclusion
To sum up , whether tensioners or impact wrench or any other tools; the best ones can make your procedures effective, easy, efficient and absolutely result oriented Talk to the experienced and right manufacturers or the suppliers and choose the right tools only..
