Hose assembly fabrication
People fabricating hose assemblies should be trained in the proper use of equipment and materials. Properly assembled fittings are vital to the integrity of a hose assembly. Incorrectly assembled fittings can separate from the hose and may cause serious injury or property damage from whipping hose, or from fire or explosion of vapour expelled from the hose.
Component inspection
Prior to assembly, examine components for:
• Configuration and types
• Cleanliness
• Damage on cover
• Nicks
• Proper diameters
• Any inside obstruction of the tubes
• Visible defects
• Damage in general
• Make sure that the lengths are suitable
• Swelling
• Machining burrs
• Corrosion
Hose fittings compatibility
Pay attention to the hose-fittings compatibility. Do not use a hose from one manufacturer with a hose fitting from another manufacturer without the consent from the same manufacturers.
Safety equipment
During fabrication, use proper safety equipment, including eye protection, respiratory protection, and
adequate ventilation.
Reuse of hose and fittings
Do not reuse:
• Field-attachable fittings that have blown or pulled off hose
• Any part of hose fittings that were permanently crimped or swaged to hose
• Hose that has been in service after system checkout
Clean inside of the hose and fittings. They may have collected contaminants during processing. Flush until they reach an optimum level of cleanliness.
