An independent device for autofrettage of diesel injection lines up to 8,000 bar is the diesel injection line autofrettage system. The majority of Poppe + Potthoff Autofrettage rigs can be expanded to a multi-chamber system and updated to 10000 bar and 12000 bar autofrettage systems. You can also alter the method similarly if your production increases. Because it may be progressively raised from one chamber to two chambers, and in some cases even up to six chambers, this specially designed autofrettage unit makes an excellent beginning system.
