Pipe Cleaning Using 3M HFE Solvents and the RAAF Oxygen System Pipe Cleaning System

Abstract

This report details the stages in the development of a novel oxygen system pipe cleaning system, and associated cleaning procedures, for use at RAAF oxygen maintenance workshops. This cleaning system uses 3M HFE solvents and pressure vessels for solvent delivery. Detailed test results and procedures are included. These tests covered RAAF oxygen system pipes in various diameters ranging from 1/8" to 1/2" in stainless steel, copper and aluminium, and various pipe connectors. The tests showed that the final system developed is able to meet the RAM cleanliness specification for oxygen systems for both non-volatile residue and particulate contamination.
