Please ask about design temperature and pressure.
Thread Content
Excuse me, if there is a piece of equipment with a design pressure of 1.45MPa, a design temperature of 220°C, a working temperature of 59.4°C, a working pressure of 0.961MPa, and the medium is gasoline, how should the following items be filled in? Is it a matter of saturated vapor pressure? Maximum operating temperature consistent with design pressure (°C). Maximum allowable operating pressure at maximum design temperature (MPag). External pressure EXT. PRESS. (actual operating pressure)
I think this should be related to the material of your equipment. It should be based on the allowable stress of various steel materials, corresponding to the maximum allowable temperature and pressure of various steel materials.
The high temperature properties of materials are well documented.
You can consult the manual on chemical equipment design, which contains calculation methods. You're sure to find what you need.
The poster can check the first volume of "Technical Regulations for Engineering Design of Process System Engineering" to determine the design temperature and pressure to see if there is anything you need.
1. The maximum operating temperature (°C) consistent with the design pressure. This should be the maximum temperature when the material pressure in the equipment reaches 1.45MPa, and this temperature must be lower than the design temperature. 2. The maximum allowable working pressure (MPag) under the maximum design temperature condition. Same as 1, it should be the pressure when the material temperature in the equipment reaches 220 degrees, and it should also be less than the design pressure. 3. External pressure should be the pressure generated by the pressurizing equipment to which the material is subjected. . . 4.EXT. PRESS. (Actual working pressure) 0.961MPa For reference only, I am just guessing. . . :lol
hehe. ． ． The design pressure is usually 1.2 to 1.4 times the working pressure. ． The maximum working temperature consistent with the design pressure and the maximum allowable working pressure under the maximum design temperature condition must be determined through actual testing or calculation.
