It is a new technology to connect pipes with pipe joints made of ferrous shape memory alloy, which provides a safe and reliable method for small and medium-sized pipe connection, especially suitable for internal coated pipe engineering, serious weld corrosion pipe engineering and fireless-connection required pipe engineering. This paper introduces the material property, major speciality and superiority of pipe joints made of ferrous shape memory alloy in detail. It also discusses the principium, operation regulation, construction peculiarity, engineering application and reliability evaluation of pipe connection with pipe joints made of ferrous shape memory alloy. In conclusion, it is of high engineering applicability to connect pipes with pipe joints made of ferrous shape memory alloy, especially suitable for fieldwork which is in bad conditions. Therefore, it has a perfect application prospect in engineering and it is worth advocating and spreading further.
