Everyone should know that, PPH storage tank It is made of a special plastic material. Therefore, due to the limitation of data, the control of pressure and temperature is not as good as that of metal data. When designing the storage tank of PPH, the normalization of its pressure and temperature must be stopped.

1. The pressure here refers to gauge pressure unless otherwise specified..

1. Working pressure: refers to the high pressure that may appear on the top of the container during normal operation.

2. Design pressure: refers to the pressure used to determine the shell thickness at the corresponding design temperature.

3. The working pressure of the vessel under the internal pressure is 1.05 times of the hydrostatic pressure.

4. The design pressure of external pressure vessel shall not be lower than the pressure that may have large internal and external pressure difference under normal operating conditions;

5. Design vacuum vessel according to external pressure. When a safety control device (such as a vacuum relief valve) is installed, the design pressure is 1.25 times of the internal and external pressure difference or the smaller value of 0.1MPa. When there is no safety control device, take 0.1MPa.

6. Test pressure: the pressure at the top of the vessel under pressure test conditions.

2、 Temperature

1. The operating temperature is the high or low temperature that may occur during the operation of the vessel shell.

2. The design temperature refers to the temperature of the plastic shell set when the container works normally under the corresponding design pressure. The value is not lower than the temperature of the shell, which can reach high temperature. For the temperature below 0 ℃, the value is not higher than the temperature of the shell, which can reach low temperature.

3. The test temperature mainly refers to the temperature of the container shell during the pressure test.

After the storage tank of PPH reaches acceptable temperature and pressure during operation, it can also prevent some operation matters that are prone to problems during operation and help you operate. PPH mixing tank
