... Abstract Failure rate is very important for the reliability and risk assessment of in-service pressure vessels. As early as in the 1970s and 1980s, the failure rate data of in-service pressure vessels has been collected in various countries, such as Europe and the United States, and in great...

... Abstract Autofrettage is a manufacturing process used during fabrication of Type 2 pressure vessels designed for usage at high pressures to enhance the fatigue life. The process locks high compressive residual stresses in the vessel’s liner wall that reduce the maximum and the mean stress...

This study used DED to process Monel K-500, a nickel-based alloy approved by the American Society Of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code. Fully dense Monel K-500 parts were printed...

... Abstract Project BRUTE has investigated weld materials extracted from the decommissioned Barsebäck 2 reactor pressure vessel. The materials investigated originate from the pressure vessel head (RPVH) and beltline regions. The performed mechanical testing include tensile, Charpy impact...

... Abstract Due to the complex working environment, the defects were easily produced on the surface of pressure vessel plate, such as scratch, wear and corrosion pit, which reduced the service life of equipment. As a new surface coating preparation technology, cold spraying technology can be used...

... Abstract The classical Tresca and von Mises strength theories have been utilized extensively for pressure vessel and pipeline design. For pressure vessel design, ASME B&PV code was developed using both Tresca and von Mises strength theories, where the yield strength (YS) was used...
