Tube end requirements – correct cleaning

Published:  18 November, 2016

This article is based on guidance provided in the British Fluid Power Association’s training course titled ‘Small Bore Tubing Integrity Course – using twin ferrule compression fittings’. Following on from our look at tube preparation in our October edition, this month, we look at tube end requirements.

As explained last month, tubing that has been selected correctly, combined with correct assembly of twin ferrule compression fittings, will provide a reliable seal on a range of applications. Maximum performance will be achieved by:

• Selecting high-quality tube.

• Compression fittings assembled in accordance with the manufacturer’s assembly procedures.

• Using tube clamps to limit the movement during normal service.

• Adhering to good tube installation practices.

In addition to correct selection and installation practices, it is also important to adhere to correct cleaning procedures.

Deburring tool

The deburring tool can be used to remove internal/external burrs from the tube end.

After deburring, the tube must be clean. Deburr vertically where possible to allow debris to fall away from the tube.

Cleaning the tube

After deburring the tube ends, the tube must be cleaned to remove any contamination from the cutting process. This can be done in various ways such as using a foam pellet system or flushing rig.
