Types of Pressure Vessels

 When the container is under pressure, the pressure will be applied to the container wall. Regardless of the shape, the pressure on the surface is always normal. It is a container whose pressure is different from atmospheric pressure. There are many kinds; thin-walled, thick-walled, sturdy tanks, transportable containers, propane cylinders and gas cylinders. It is a container that contains liquid, steam or gas whose pressure is different from atmospheric pressure at the same height. Generally, if the radius is greater than 5 times the wall thickness, then a is considered thin-walled. In this case, it can be considered that the tension in the wall is uniform. Thin walls are very common. There are two specific types; cylindrical pressure vessels and spherical pressure vessels. In this case, it can be considered that the tension in the wall is uniform. The stress in a thin-walled container varies from a maximum value inside the container to a minimum value outside the container. The storage tank is a type of thin-walled pressure vessel.

The thick wall means that the wall is 10% thicker than the inner diameter. Thick-walled pressure components that operate at high temperatures in power stations, chemical and petrochemical industries can be damaged by high temperatures, mechanical stress, and corrosive environments. These factors can lead to thermal fatigue, creep-fatigue and other processes that lead to degradation. When subjected to internal and external pressures, tension and strain exist in thick-walled pressure vessels. They have high tensile strength and can withstand the maximum load.

 

Removable containers are the most common and probably the most overlooked type. These are mass-produced and must be tested for propane and gas every 10 years. The steel pressure vessel is designed to perform dual air storage and partial separation of moisture. These are equipped with all the standards to be able to work safely. The pressure vessel must be designed to operate efficiently under high pressure. There must be no cracks or leaks to ensure complete safety to the environment. Cracked and damaged containers can cause leakage or breakage. Damage may cause significant loss of life and property. For the health and safety of workers, safety design, installation, operation and maintenance must be carried out in accordance with applicable codes and standards.
