Enerpac’s GT-Series hydraulic bolt tensioners, in capacities up to 2845kN (320 tonne) at 1500 bar, are particularly suitable for achieving known and accurate bolt loads across multiple applications, such as pipelines and flanges.
This precise, safe and time-saving fastening technology is particularly useful in applications involving critical tolerances and multiple bolting tasks on heavy industrial processing, power generation and resource exploration and development equipment and infrastructure.
According to the company, a major advantage demonstrated at QAL is that multiple bolts can be fastened at one time using exactly the same pressure from the same power source.
This ability to “daisy chain” hydraulic tensioners gives even load across a bolted surface, which is a major advantage in the industries in which they are used, especially where high technology, high pressure equipment is involved, the companys says.
