Autofrettage System

The autofrettage system applies ultra-high pressure to cylindrical components, producing localized plastic deformation and beneficial residual compressive stress at the bore after depressurization. This offsets operating stress, suppresses crack growth, and greatly improves fatigue life in cyclically loaded high-pressure tubes, actuator cylinders, valves, and gun barrels.

· The system provides stable pressure output for autofrettage at different pressure ratings.

· Intelligent high- and low-pressure monitoring, multiple pressure safeguards, pressure-relief protection, emergency shutdown, and safe venting.

· High structural strength and reliable guarding contain fragment impact and enable remote operation.

· High-precision pressure, flow, and temperature sensors enable real-time monitoring, timed pressure holding, and test-data recording.

· A wide pressure adjustment range with programmable, automatically controlled pressurization rate.

· Multiple outlets support multi-station autofrettage, with automatic recording, real-time pressure curves, and process-report generation.

· Applies ultra-high pressure to common rails and high-pressure fuel tubes to create residual compressive stress and significantly improve fatigue life under cyclic pressure.

· Strengthens ultra-high-pressure vessels and reactors, producing a more uniform wall-stress distribution and higher pressure capacity at the same wall thickness.

· Introduces beneficial residual stress to improve the strength and fatigue resistance of gun barrels and nuclear-reactor components.
