Autofrettage is a method for increasing fatigue strength of components for use at high and pulsating pressures. In short, Autofrettage compresses a container’s inner surface, making better use of the material’s structural properties. The process can reduce fatigue concerns in pulsating applications and lets engineers reduce tubing thickness in high-pressure applications without sacrificing strength, life, or safety. The autofrettage method is based on the reciprocal relationship of the plasticized inner zone and the elastically deformed outer zone. The components are placed under so much pressure that their interiors become plastically deformed. After relaxing, pressure stresses are created in these areas, which prevent the outer areas from reforming to their original shape. Instead, it remains stretched. This prevents crack formation in the later application, increases the service life of

The Poppe + Potthoff impulse test stands test the operating or fatigue strength of various metal and plastic components. The endurance test in our high-pressure test systems simulates the life-cycle under varying loads. The failure tests thus show the potential weaknesses of the components with respect to design and material. The pressure is optionally modulated as a sine wave, trapezoid curve or needle pulse. Our test stands are characterized by a special ergonomics and are designed by Poppe + Potthoff machine design. Due to our flexible modular design, our machines are very variable, so that the pressure and volume range is designed according to the customer’s requirements. Of course, our systems are UL or CE compliant as required. In addition, we offer you service and support directly on-site.
