Turn to us for autofrettage solutions.

The process of pre-stressing a material to improve its performance and reliability is known as autofrettage. At A & A Machine & Fabrication LLC, autofrettage is one of the many services we offer. We can perform autofrettage on high-pressure tubing (LDPE/EVA), high-pressure fittings (cylinders, blocks, and quills), and pressure vessels.

Autofrettage in La Marque, Texas

When we perform autofrettage on high-pressure tubing, the process involves pressurizing the material to 120-140ksi to deform the tube’s bore. We then move the plastic/elastic deformation interface toward the outer diameter. If the pressure were to continually increase, the deformation would eventually progress until it reached the outside wall, causing plastic collapse or rupture.

During autofrettage, we control the pressure to place this plastic region at a desired radial distance from the bore’s center. When we are done with this process, residual compressive stress remains in the bore and lowers stresses on any subsequent pressurization. This allows for a longer service life for that particular part.

We provide autofrettage solutions here in the La Marque, Texas area, and we are ready to complete your project with excellence. Customer satisfaction is always our top priority, and we will do whatever it takes to complete your autofrettage project according to your exact specifications.
