Memory alloy pipe connector
Aviation hydraulic pipe joint is one of the important components that affect aircraft safety. Highly reliable and lightweight pipe joint is an important guarantee for aircraft safety and economy. Shape memory alloy (SMA) pipe joint is a high-performance aviation pipe joint made of shape memory alloy (nitife, NiTiNb), which can be used in 13.8mpa ~ 55.2mpa pressure systems. When the memory alloy pipe joint is in the martensite state (liquid nitrogen / alcohol / petroleum ether), use the preformed pipe joint (the inner diameter is slightly smaller than the outer diameter of the pipe) with the corresponding diameter expanding mandrel to make the inner diameter slightly larger than the outer diameter of the pipe. During installation, take out the pipe joint from the liquid nitrogen and put it in the installation position. When the temperature of the pipe joint gradually rises, it will shrink and generate sufficient restoring force to clamp the pipe. At the same time, the inner ridge of the pipe joint is embedded into the pipe, A gold to metal seal is formed so that the connection has high connection strength and excellent sealing performance.
