Pressure vessels of Category 1, Category 2 and Category 3 are as follows:
Pressure vessels are closed devices used to contain gases or liquids and are widely used in industry, scientific research, medical and other fields. According to the nature of use and process requirements, pressure vessels are divided into Category 1, Category 2 and Category 3.
Category 1 pressure vessels refer to pressure vessels used to contain extremely hazardous media or extremely toxic media. This type of pressure vessel usually has higher operating pressure and temperature and larger volume, so it requires particularly strict safety measures. The design, manufacturing, inspection, and use of Class 1 pressure vessels must comply with relevant national regulations and standards to ensure their safety and reliability.
Category 2 pressure vessels refer to pressure vessels used to contain highly hazardous media or with a high degree of toxicity. The use conditions of this type of pressure vessel are looser than Class 1 pressure vessels, but certain safety measures still need to be taken. The design, manufacturing, inspection, and use of Class 2 pressure vessels need to comply with relevant regulations and standards to ensure their safety and reliability.
Category 3 pressure vessels refer to pressure vessels used to contain general media or those with low toxicity. The use conditions of this type of pressure vessel are relatively simple, so the safety requirements are relatively low. The design, manufacturing, inspection, and use of Class 3 pressure vessels need to comply with relevant regulations and standards to ensure their safety and reliability.
In short, the classification of pressure vessels is determined based on their nature of use and process requirements. Different types of pressure vessels have different usage conditions and safety requirements, so corresponding safety measures need to be taken during use to ensure their safety and reliability. At the same time, for different types of pressure vessels, their design, manufacturing, inspection, use and other aspects also need to comply with different regulations and standards to ensure that they meet relevant requirements.
