Hi-Force
Hi-Force is a leading global manufacturer of high pressure hydraulic tools and offers a range of hydraulic bolt tensioners for topside and sub-sea applications, operating at maximum pressures of 1500 bar (21,750 psi).
Available with imperial bolt sizes of 3⁄4” to 4” and metric bolt sizes of M16 to M100, the STS topside and SBT spring return tensioner ranges offer up to 26 imperial and 32 metric models. Both these ranges are designed primarily for topside operations in a wide variety of applications including pipeline flanges, heat exchangers and pressure vessels.
The SBT range offers the additional feature of the spring assisted return piston which reduces bolt tensioning cycle times considerably. Once the hydraulic pressure is released, the tensioner piston automatically starts to retract, thus removing the need to manually wind down the threaded puller.
The STU sub-sea tensioners are designed and manufactured to suit the demanding requirements
of divers operating in harsh sub-sea environments. With an easy to operate two piece design comprising of a quick fit/release threaded puller and a hydraulic load cell with integral bridge, the STU series offer a reliable and cost effective method of tensioning sub-sea imperial bolted joints up to 3 1⁄2” and metric bolted joints up to M90.
Suitable pumps for the bolt tensioner ranges include the AHP275BTU and AHP2-237BTU air driven pumps as well as the HPX1500BTU manually
operated pump. Each pump operates at a maximum working pressure of 1500 bar and is supplied complete with a pressure gauge and quick connect couplings for ease of use.
With the best available technology, world class manufacturing principles and the accredited ISO9001:2008 procedures, quality control is assured in the Hi-Force brand. “All the components of the hydraulic bolt tensioners are designed, produced and tested at our manufacturing facility in Daventry on a fleet of twelve Mori Seiki machines and using only the highest quality materials. All our products, for example the tensioner load cells, are issued with a unique serial number which gives us the ability to identify precisely the material certification, machining batch numbers, heat treatment process and finally the build and testing information,” says Chris Dickinson, Hi-Force Group Operations Director.
