Composite cylinders: conditioning gas in glass fibre cylinders

Composite cylinder inspection: new activity in full swing

When the first composite cylinders reached their expiry date, we developed and installed a specific inspection line for these cylinders

Composite cylinder particularities

The glass fibre cylinder inserted in rigid plastic housing needs to go through a specific, innovative inspection process, which we have developed.

Retesting

  • Valve disassembly and draining
  • Mechanical resistance testing with 30 bars pressure
  • External and internal visual inspection (flaw library validated by the cylinder manufacturer)
  • Plastic housing replaced if necessary
  • Valve inspection
  • Weighing
  • Regulatory marking of retesting
