On-site machining challenges are often unique, which makes for an interesting life for the Project Engineer. The downside is that standard flange facing machine equipment quite often isn’t sufficient to get the job done correctly.

But before you either turn down your next flange facing job, or invest in a new product, it’s worth checking to see if any accessories can be used to convert your existing machines to suit a different purpose. In this article, we give an overview of the various accessories available to extend the capabilities of Mirage flange facing machines.

If you are an experienced field machinist, no doubt you'll have your favourite reference books and pocket guides you can turn to when either working on-site, or in the office planning your next project.

A book that contains absolutely everything the on-site machinist needs to know would be a great resource, but this is a big ask and it certainly wouldn't be ‘pocket-sized’.

Fortunately, there's plenty of great engineering resources online and the good news is many of them are completely free. So, to help you get fully equipped with extra information, we've found 6 useful websites you may want to look at and bookmark for later reference.

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.
