Shrink Fitting By: Olivia Newton
Definition Shrink Fitting-A technique in which pieces of a structure are heated or cooled, employing the phenomenon of thermal expansion, to make a joint.
Examples: Thermal expansion of a piece of metallic drainpipe can make a builder fit a cooler piece to it. The adjoined pieces reach the same temperature and the joints are strained and stronger. Fitting an iron strip around the edge or a cartwheel. The strip is then heated and expands around the wheel’s diameter, and is fit around it.
Risks Risks when shrink fitting include limits of parts exceeding and parts becoming deformed.
Cryogenic Institute of New England At the Cryogenic Institute of New England, they have accomplished many goals involving shrink fitting, with numerous projects.
Their Projects Some of their projects they have successfully completed include very large steel pipes, sized at over 24 inches diameter to intricate miniaturized parts.
Shrink Fitting It helps us with many different things to date, and it is used everyday to create things, such as jeans.
