use of pressure vessel plates
(1) Definition: In addition to requiring a certain strength and toughness, it also requires uniform material and strictly limits harmful defects.
(2) Type: According to the composition classification can be divided into carbon steel plate, alloy steel plate two categories; According to the strength classification can be divided into high, medium, low pressure steel plate; According to the use of the environment can be divided into high, medium and low temperature steel plate and corrosion resistant steel plate.
(3) Main production plants and import main production countries:
① Domestic main production plants: Wugang, Angang, Laisteel, Shanghai Steel, Baotou Steel, Sansteel, etc.;
② Major foreign exporting countries and regions: Japan, Russia, Germany, Eastern Europe and other countries and regions.
Pressure vessel plates are steel plates used in the manufacture of steam boilers, pressure vessels and other pressure vessel structures. Because this steel plate is subjected to a certain air pressure and water pressure, as well as different temperature environments, such as high, medium, low temperature, etc., the requirements for this steel plate are more strict.
