Autofrettage system for high-pressure applications PPM 320

Autofrettage Machines up to 15,0000 bar What is Autofrettage? Increase Components Fatigue Strength in Pulsating Pressures 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 components, and thus offers the corresponding cost reduction potentials. For High-pressure Components Poppe + Potthoff Maschinenbau offer equipment for the precisely defined Autofrettage of prototypes and standard components, which are subject to a constant change of high and low pressures. Applications Components for high-pressure hydraulic and diesel injection systems Pressure vessels, gas cylinders and components for water-jet cutting systems Pipes for chemical plant construction, plant and power station construction Pressure sensors and transmitters
