Fluid & Gaz Transport
Nimesis Technology is specialized in the integration of specific components in Shape Memory Alloys (SMA) used for gas or fluid transport requiring a temperature control. The Shape Memory Alloys components are in the form of cable, spring or strip and they react to the change of temperature by giving a mechanical or electro-mechanical action.
Some other tubular components can also handle the link between two tubes in case of difficulty or impossibility to weld.
Shape memory coupling sleeve
A coupling sleeve is expanded and putted around the two extremities of the tube. When heating, the coupling sleeve gets back to its contracted shape and ensures a perfect sealing. It can replace a welding, having the added value that this sealing is dismountable.
A Shape Memory Alloys component, a spring, a strip or a cable takes back its original shape above a given temperature. In this way, an alarm can be activated, an electrical or gas circuit can be broken and an orifice can be opened or closed.
The change of the surrounding environment’s temperature in a pipe causes more or less complex changes of shape of a SMA component (pierced plate, blade…). Consequently, the fluid flow is changed, slowed or speeded up.
A fluid flow can be controlled using SMA flow regulator, with temperature changes of the environment. When triggered the SMA component will change shape and thus impact the fluid flow.
Slack adjustment device
Many devices subjected to fast temperature variations are degraded by the distension of the elements. Some ingenious Shape Memory Alloys components can balance this distension phenomenon.
