Design pressure: new challenges for veteran revolutionaries
Thread Content
For a certain project, it involves an atmospheric-pressure reactor; ~3 kilograms of nitrogen is used for pressurizing the material, while the designed pressure is set at 4 kilograms. The discharge pipeline operates at atmospheric pressure, with a design pressure of 2 kilograms. Refer to \"Determination of Design Pressure and Design Temperature for Equipment and Piping Systems\" (HG/T 20570.1-95), 2.0.4.3: The design pressure of all pipes connected to equipment shall be no less than the design pressure of the equipment to which they are connected. How can this problem be solved?
Follow the regulations; in fact, for pipes, the design pressures of 4 kilograms and 2 kilograms have little impact on the wall thickness
How should the relevant parameters in the equipment list and the pipeline characteristics table be filled in to ensure consistency and appropriateness?
The pipeline characteristic table usually has a remarks column; the design pressure of the pipeline is set according to the design pressure of the equipment, which is 4 kilograms. Note in the remarks section that the design pressure for pipeline operation on weekdays is 2 kg.
