The effect of design pressure
Thread Content
Let’s discuss the role of design pressure in piping. Since there is no definition of pipeline design pressure in the standards, I’m really confused
The selection of pipes is related to the design temperature and design pressure.
The load-bearing capacity of pipes is related to both weight and pressure
The design of pipes is related to the design temperature and design pressure.
The design pressure is usually associated with a specific pressure rating. When designing pipes, once the fluid flowing through them, as well as the temperature and pressure, are known, an appropriate pressure rating is selected, and corresponding parameters such as the design pressure and wall thickness are determined through design checks. . . .
““There is no definition of pipeline design pressure in the standards” – it’s just that you haven’t come into contact with them enough; there are indeed standards
I remember there was a post about design pressure and design temperature; the original poster can take a look.
For equipment, the design pressure refers to the maximum pressure specified at the top of the vessel (including additional conditions of the process system). For pipes, the design pressure refers to the pressure under the most severe conditions among all the combinations of operating pressures and temperatures that may occur in the piping system under normal operating conditions.
Chapter 1 of the \"Code for Design of Process System Engineering\" (HG/T20570-1995) and the \"Code for Design of Industrial Metal Piping\" (GB50316-2008) should both address the issue of piping design pressure, right?
