This photgraph shows: (1) a specimen of a brass sleeve, hydraulically expanded into a brass tube, sectioned to show the assembly and (2) a brass sleeve hydraulically expanded into a brass tube with drilled holes in the tube to show the effect of the hydroexpanding of the sleeve.
We recommend the HydroPro® systems for hydroexpanding tubes into tubesheets and sleeves into tube ends. We recommend the BoilerPro® system for hydroexpanding boiler tubes into boiler drums and tubesheets. The HydroPro® and BoilerPro® hydraulic expanding systems are available from HydroPro, Inc. of San Jose, California.
