Faber cylinders comply with the most stringent specifications set down by International Bodies and Local Authorities.
All over the world Faber is well known for the comprehensive range of safety and standard approvals of its cylinders.
A list of Faber Approvals is available.
The design of Faber cylinders uses not only specified calculation formulae but also the finite element linear analysis.
The calculated data are then verified experimentally using strain-gauge measurements.
The materials (steel, fibres, resins, etc.) are carefully selected depending on their eventual use conditions, after verifying the chemical, physical, mechanical characteristics and, where necessary, their stress-corrosion resistance.
The fracture mechanics analysis of the steel allows us to define the maximum permissible defects in the cylinders, in order to enable us:
The cylinders' surface protection is considered to be a function of the various environmental conditions of use and of the various corrosion agents.
Design Tests and Analysis are performed for new design approvals:
On materials - Mechanical tests: tensile, elongation, impact, toughness, ductility, stress-cracking - Chemical analysis On prototype cylinders (check of safety performances) - Hydraulic burst test - Pressure cycling test - Ductility and impact resistance test - Bonfire test (resistance to fire) - Gunfire test (resistance to bullet penetration) - Environmental test - Extreme temperatures monotonic and cycling tests - Flawed cylinder burst test
During production all the cylinders are subject to:
