Mechanical malfunctions
Damage to mechanical equipment can be caused by design or manufacturing defects, misuse, material degradation due to use in severe conditions or even a lack of maintenance.
Our scope
Air Liquide CTE conducts investigations to determine the causes of the damage.
We carry out these investigations after component failures, observation of cracks, or any other failure of mechanical parts.
What are the risks associated with mechanical failures ?
Defective equipment or accessories can cause dangerous situations (gas or liquid leakage, explosion, etc.) for users.
What are the consequences ? Asphyxiation, burns or injuries.
Which equipment can we analyse at CTE ?
Damaged materials and components, after accident or incident :
- After leaks, ruptures, cracks, etc.
- Analysis of metallurgical defects.
- Identification of technical causes.
The following equipment :
- Valves, hoses, regulators, fittings.
- Gas cylinders, tubes, cryogenic containers.
- Welded components.
What are the most common damage mechanisms seen ?
-
Stress corrosion
-
Dezincification of brass
-
Hydrogen embrittlement
-
Fatigue cracks
-
Ductile rupture
-
Crevice corrosion
-
Leak on gas cylinder valve
-
Abnormal rupture on a disc
Our testing activities
CTE offers tests on oxygen safety, cylinder conformity and equipment performance.
