Metal
Stitching
Metal Stitching is a cold repair process
for broken and cracked castings. Metal stitching can be performed on-site
without the need for major disassembly. The result is a repair stronger
than the original design. For more detailed information about metal
stitching, click here. Runner
Repairs
Runners often suffer metal loss or develop
cracks due to foreign objects, cavitation, and abnormal operating
conditions. The Schulz Group repairs minor cavitation areas, runner
surfaces and discharge ring surfaces if required.

CO2
Dry Ice Cleaning
Dry ice cleaning is a unique, technologically
advanced cleaning method that is easy to use, harmless to the environment,
and exceedingly cost effective. The CO2 cleaning system uses rice-like dry
ice pellets, called DRICE, blasted at subsonic or supersonic speeds to
remove surface contaminates.
