Design pressure of storage tank and heat exchanger

This post was last edited by sxf1028102800 on 2023-9-7 at 12:03. If the design pressure of storage tanks and heat exchangers is around 1.0 MPa, and a process accident occurs causing these devices to experience pressures higher than their design values, could the devices tear? By how much above the equipment’s design pressure does it usually tear? Please discuss it, thank you
If a storage tank or heat exchanger equipment exceeds its design pressure, deformation, warping, and rupture (tearing) of the equipment usually occur. This is because the design pressure of a device is determined based on the strength and stability of its materials; exceeding this design pressure causes the device to be unable to withstand internal pressures, leading to rupture. Generally speaking, the design pressure at which a device will tear depends on various factors, including the device’s size, the strength and stability of the materials used, and the rationality of the mechanical design. Different devices may have different tearing pressures. During the engineering design process, the design pressure of the equipment should be selected appropriately based on its operating conditions and requirements, with relevant calculations and analyses carried out to ensure that the equipment can operate safely under normal conditions as well as in the event of accidents. At the same time, appropriate safety measures and emergency response plans must also be established to ensure that actions can be taken promptly in case of abnormalities, thereby preventing damage to the equipment and accidents from occurring. .
