Hydraulic Bolt Tensioner Compatible Flange Suppliers

Destec designs the standard Desflex Compact Flange to accept hydraulic bolt tensioners, giving installation and maintenance teams a controlled, repeatable method of achieving the correct bolt load without relying on manual torque wrenching alone. Hydraulic tensioning applies a consistent, evenly distributed load across the bolt circle, which suits the flange's patented spherical nut design and helps maintain the controlled flange rotation the toe feature is designed to limit. This compatibility matters most on larger flange sizes or higher pressure ratings, where manual torque methods become impractical or unreliable, and on offshore or subsea projects where installation contractors typically have hydraulic tensioning equipment as standard kit. Flanges designed to accept hydraulic tensioning are available across the full Desflex size and material range, in both standard and swivel weld neck configurations.
