Pressure vessels are used for a variety of applications, most often in energy and transportation sectors.
Pressure vessel quality (PVQ) plate is used to produce pressure vessels due to its tensile strength, notch toughness, ductility and fatigue characteristics.
Common grades: ASTM A516, A537 Class1, 16Mo3, Q345R
PVQ Plate PropertiesBefore examining the properties of PVQ grades, here are a few terms used to describe the properties of steel, defined:
Strength: the load the steel can bear. Steel strength is determined by yield point and tensile strength. A yield point is the point at which a material is stressed to the point where it deforms but does not break. Tensile strength is the amount of stress needed for the material to break.
Notch Toughness: the level of impact steel can absorb before denting, typically measured by a Charpy Impact test.
Ductility: the capability of a material to be stretched out before it becomes weak or brittle. Ductility is measured by elongation, which is the percent the length of a stretched material increases before it breaks.
Pressure vessels are defined as closed containers that hold gases or liquids at a pressure substantially different than the ambient pressure. Since reliability and safety are so critical to pressure vessels, their production is regulated and tested for quality.
