Precautions for ensuring the safe operation of pressure vessels tanks

A cryogenic pressure vessel storage tank is a closed device that holds a gas or a liquid and carries a certain pressure. This equipment is recognized as a hazardous equipment, so to ensure the safe operation of the equipment, we should pay attention to the following:

Smooth operation: During the operation of the pressure vessel tanks, frequent changes in pressure and large fluctuations are unfavorable to the fatigue damage of the container. The operating pressure should be kept as stable as possible. At the same time, during the operation of the container, sudden changes in the temperature of the housing should also be avoided to avoid excessive temperature stress.

Prevent overload: Prevent overloading of vacuum pressure tanks, mainly to prevent overpressure. The reaction vessel should strictly control the feed amount and reaction temperature to prevent the reaction from being out of control and over-pressurize the container. When the storage container is filled and fed, it must be strictly measured to prevent over-loading and prevent the material from being over-pressed by thermal expansion.

Condition monitoring: The vacuum pressure vessel operator should constantly supervise the working condition of the container during the operation of the container, timely discover the abnormal situation in the operation of the container, and take corresponding measures to ensure safe operation. The supervisory control of the operating state of the container is mainly carried out in terms of process conditions, equipment conditions, safety devices and the like.

Emergency shutdown: When one of the following abnormal phenomena occurs in the pressure vessel, the operator should immediately take emergency measures and report the relevant departments of the unit in accordance with the prescribed procedures. These phenomena mainly include: working pressure, rapid change of medium, medium temperature or wall temperature exceeding the allowable value, and measures can still not be effectively controlled; cracks, bulges, deformation, leakage, etc., which are the main pressure components, endanger the safety; safety accessories Failure; damage to the pipe and fasteners, it is difficult to ensure safe operation; the fire directly threatens the safe operation of the pressure vessel tanks; overfilling; the liquid level is out of control; the pressure vessel and the pipeline are seriously vibrated, endangering safe operation.
