Typical applications include: pressure test stands, burst testing,
autofrettage, chemical injection, gauge testing, work holding, jacking and lifting systems and valve actuation.
To counter this the US Naval Air Systems Command is funding Connecticut company Flightware to develop a surface protection process called "inverse
autofrettage".
has developed turnkey ultra high-pressure leak test systems and
autofrettage systems for R&D and production of diesel engine components.
This being said, the actual tube-sections used in project Babylon were pre-stressed, layered, compressed steel components produced through a mechanism called "
autofrettage." The latter is a process used almost exclusively for the manufacture of gun barrels.
In forming, they will be offering help in sizing, punching,
autofrettage; the redistribution of stresses; and shock hardening.
Their product range now includes single-stage gas guns, two-stage light-gas guns, firing-range chambers, detonation chambers, explosion-containment chambers, Split-Hopkinson bars for compression or direct-tensile tests and
autofrettage machines for gun barrels.
