Torispherical Head
Pressure vessels Pressure vessels are specialized containers designed to hold gases or liquids at pressures significantly different from the surrounding environment. These vessels are integral components across diverse industries, including chemical processing, oil and gas, and power generation. Typically constructed … Continue reading
ASME Torispherical Head Detail Dimension for Pressure Vessel
In the design and construction of pressure vessels, various types of heads are used to ensure the structural integrity and safety of the vessel. One commonly used type of head is the torispherical head, which includes the ASME flanged and … Continue reading
Understanding Minimum Design Metal Temperature (MDMT)
The Minimum Design Metal Temperature (MDMT) is a crucial factor in engineering and manufacturing, particularly for pressure vessels and piping systems. It represents the lowest permissible temperature at which a material can be safely subjected to design loads without experiencing … Continue reading
Acoustic Emission Testing – Data Analysis
The data obtained from an acoustic emission test of a pressure vessel are analyzed to determine the existence of flaws and their locations in the shell of the vessel. Accurate analysis of the data is highly dependent upon the expertise … Continue reading
Acoustic Emission Testing – Physical Principles
Sonic impulses are emitted by a flaw in a ductile material subjected to a gradually increasing applied stress, due to the release of strain energy in the intensified stress field associated with the flaw. The release of strain energy creates … Continue reading
Acoustic Emission Testing (AE)
AE was developed to assess the integrity of pressure-containing equipment in the nuclear power industry. Acoustic sensors are attached to the O.D. surface of the equipment to detect and locate flaws in the material during a pressure test. AE can … Continue reading
Acoustic Emission Testing – Acoustic Sensors and Instrumentation
Most acoustic sensors used for acoustic emission testing of pressure vessels employ piezoelectric ceramic elements that convert the stress waves (i.e., acoustic emissions) propagating through the vessel shell into electrical impulses. These sensors are usually attached to the vessel shell … Continue reading
Inspection of Spheres
In general, the practices that apply to pressure vessels also apply to spheres although the techniques may vary. The tall legs necessary to support spheres should be carefully inspected to determine the condition of the fireproofing and the rain seals. … Continue reading
