... 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...

... Abstract Pressure vessels play important roles in pressurized static equipment systems. In the oil and gas industry, for example, they are used to perform the process function, separation, filtration, and storage. Given the role of pressure vessel, which is subject to elevated pressure...

... windows. In particular, for cracked components inspected by NDE personnel with varying probability of detection (POD) qualifications, we find both Approach (1) and Approach (2) inadequate as a guide for maintenance decision-making and compliance with the ASME Boiler and Pressure Vessel Section XI Division...

... potential for in-situ alloying, which are highly desirable attributes for pressure vessel applications. 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...

... of the pressure vessel. The material of the head was SUS 304 austenite stainless steel. Failure analysis was conducted to investigate the cause of cracking. The testing and measurement included chemical composition analysis, metallographic examination, fracture surface observation and deposit elements analysis...

... Abstract The American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC) Committee has recently developed a new Section XI (Nuclear Components Inspection) Division 2 Code [1] named “Reliability and Integrity Management (RIM).” RIM incorporates a new concept known...

... Abstract Today the ASME Boiler and Pressure Vessel Code Section VIII (ASME Code) covers pressure vessels for design pressure above 15 psi (100 kPa) but not for design pressures below 15 psi. Manufacturers of pressure vessels under 10ft (3048mm) and with design pressure under 15 psi (100 kPa...

... Abstract Pressure vessels can be subjected to various external local forces and moments acting in combination with main internal pressure. As a result of the stress system set up, and in the presence of attachment welds, surface cracks can occur on the interior and exterior walls...

... Abstract Section VIII of the Boiler and Pressure Vessel Code is introducing the use of acrylics as a pressure vessel material. The design method is specified in ASME PVHO-1, Safety Standard for Pressure Vessels for Human Occupancy. The current method relies upon an empirical method developed...

... Abstract The pressure vessels are connected by pipelines to form a system. Thermal expansion of the pipeline imposes an additional load on the nozzle of the connected vessel. There are two methods to deal with the thermal expansion load of pipeline in the design of pressure vessel...

... Abstract Control of carbon macro-segregation in the steel-making process for large steel forgings is of great importance in order to achieve the material properties and structural reliability required for the pressure vessels of nuclear power plant components. It is well known that high carbon...

... Abstract The Steam Permeameter Cell is a laboratory-scale pressure vessel used to perform high pressure, high temperature testing on well cement slurries. Initial sizing of the concentric, two chamber vessel was based on design by rule concepts in the ASME Boiler and Pressure Vessel Code...

... Abstract In order to eliminate these welding residual stress which produced in the process of pressure vessel manufacturing and assembling, post-weld heat treatment is required for the weld structure. The Large size and complex structure pressure vessel which cannot integral post-welding heat...

... Abstract In recent years, a large number of pressure vessels for the petrochemical plants built in China in the 20th century have been in service for more than 20 years. The Chinese pressure vessel safety specification TSG 21-2016 “Supervision Regulation on Safety Technology for Stationary...

... Abstract Bonded composite repairs are commonly used as both a temporary and permanent repair method to restore damaged pressure vessels and pipelines. This repair approach is used in a wide variety of industries, including the oil and gas industry. Design and qualification of repair method have...

... Abstract When a small crack is detected in a pressure vessel or piping, we can estimate the fatigue life of the vessel or piping by applying the classical law of fracture mechanics for crack growth if we are certain that the crack growth exponent is correct and the crack geometry is a simple...

... Abstract Analyzing and solving the problem of practical cylinder-cylinder pressure vessel intersections is challenging when using a finite element approach. Although numerous theoretical and finite element solutions have been developed for the cylinder-cylinder intersection problem...
