BELIUM BBHN series hydraulic nuts are designed and manufactured for inspection and regular maintenance of flange connection. Unlike traditional hydraulic bolt tensioners, the BELIUM BBHN series
hydraulic nuts are designed to permanently replace the flange with a standard hex nut. Once the hydraulic tension force is applied to the bolt, the hydraulic tensile force is permanently preserved by the built-in mechanical load ring of the hydraulic nut.
The BBHN Series Hydraulic Nuts standard thread sizes are from M22 to M100, other sizes can be available on request.
