Applications for compact flanges

Compact Flanges are commonly used in offshore rigs and various subsea installations including;

  • Flexible and rigid risers
  • Subsea production flowlines
  • Christmas trees
  • Subsea gas-lift and water injection flowlines
  • Subsea metering equipment
  • Subsea, valves, pumps and compressors

Joints of this type are thought to be stronger than the actual pipe they are connecting and also have better fatigue properties than the flange pipe weld. This means they are specified for critical areas where conventional flanges are not accepted. There are commonly 3 sealing faces in a compact flange joint, with the ‘heel’ sealing the internal bore.

The Casing Double Pin Drill

In our previous blog we told you about our band saw and how it performed during workshop trials. This time we take a look at the DDU1636 double drill unit which was also designed by the Mirage team for offshore decommissioning projects.

In 2012 the Mirage DDU was runner-up product at the World Oil Awards on the ‘Health, Safety, and Environment / Sustainable Development Offshore Award’ category.

The machine is mostly used for drilling lifting holes into casings, which can then be severed using a portable band saw and lifted out of position. The robust construction and carbide tipped cutters makes it an ideal tool for cutting through different materials as used in cemented casing strings.
