Destec Engineering Ltd. has 6 products.

Compact Flange

The first original Compact Flange designed to meet the requirements of ASME VIII Div 1 & 2, Type Approved & Fire Tested.

Offering weight savings of up to 88% when compared to the equivalent ANSI Flange. Quick and easy make-up with superior mechanical strength and fatigue performance.

The Desflex Compact Flange is ideal for both topsides and sub-sea applications where minimum weight is essential and reduced maintenance.

  • Both standard and swivel type weld neck flanges are available in Carbon, Stainless, Alloy and Duplex steels.
  • Desflex Flanges are Type Approved and have successfully passed API Fire tests.
  • Available to meet NORSOK standards
  • The patented design includes several unique features including spherical nuts on the bolting to reduce bolt stresses and a toe at the outside diameter to limit Flange rotation and to prevent overstressing of the flange.
  • Reusable metal-to-metal Seal
  • The Destec D and RD range of all metal Seal Rings are used.

On Site Services

Our wide range of versatile in-house designed and manufactured portable machine tools are well equipped to take on problems where accuracy and a good surface finish are paramount. Over the years we have added other associated on-site services, bolt tensioning, on-line leak sealing, polymer coating and repairs, and welding. Our world-wide service successfully operates throughout all industries including chemical/petrochemical plants, offshore, power generation, renewable energy, nuclear, marine, steel, mining, ports, docks and harbors.

By using multi-disciplined trained technicians, the client benefits by having less personnel on site.

  • On-Site Machining
  • Regenerator & Vessel Head Removal
  • Bolt Tensioning
  • On-Line Leak Sealing
  • Special Purpose Machine Tools

GSB Subsea Single Bolt Connector

The Destec GSB Subsea Single Bolt Connector is a purpose designed unit for operations where a conventional four bolt G-Range pipe connection would be impractical.

G-Range Hub Clamp Connectors

The Type Approved & Fire Tested G-Range clamp connector provides an ideal solution to piping installations, used extensively in production manifold, flow line and valve installations.

Due to their efficiency, lightness and reliability, together with extreme qualities of leak tightness, the G-Range pipe connection offers significant benefits for use in industrial plant in a wide variety of applications. Although designed primarily for adverse pressure and temperature conditions, more modest applications can be considered due to ease-of-installation and assembly, particularly when compared with the alignment and tightening of standard flanges.

The G-Range pipe connection comprises: a pair of hubs for welding to the pipe (similar to a flange); a clamp set, which can be rotated around the hubs to suit the most practical positions; and a seal ring.

The seal ring is a modified cone ring giving excellent leak tightness properties under the most severe conditions of pressure and/or thermal shock.

On assembly the taper joint faces compress the seal ring radially. The sealing force is provided by the stored energy in the stressed seal ring, any internal pressure intensifies the sealing action.
