Pressure vessel which contain
Gas cylinder, acetylene cylinder, oxygen tanks, boiler, pressure cooker, air pump storage tanks, etc.
Pressure vessel is airtight certain media or vacuum containers, is divided into four categories: reaction, heat transfer, separation, storage containers.
Pressure vessel classification method (1) the basic division: shall be based on the characteristics of medium in the division of pressure vessel category classification according to the following requirements to choose the figure, and then according to the design pressure p (MPa) and volume V (L), mark the coordinate points, determine the type of pressure vessel. Category: (2) the cavity pressure vessel cavity pressure vessel (such as tube side and shell side of heat exchanger, jacketed vessels, etc.) according to the categories of high pressure cavity as the container type and use the management according to the category. But shall, in accordance with the pressure of each cavity each category respectively puts forward the design, manufacture technical requirements. Category for each pressure cavity to delimit, design pressure in the pressure chamber design pressure, volume take the pressure chamber geometry volume. (3) with the cavity when the medium pressure vessel classification: a pressure chamber with a variety of media, according to the categories of high medium category. (4) medium content of tiny pressure vessel classification: when a hazardous substance content in the medium very hour, ought to according to the content of its hazard degree and its comprehensive consideration, according to the pressure vessel design units to medium group is divided into categories. (5) the classification of the special circumstances
