[0002] In air conditioning pipe manufacturing, the pressure test is a critical quality control test conducted on air conditioning piping systems or their components. Its purpose is to verify the sealing performance, structural strength, and safety performance of the piping under specific pressure conditions, ensuring that it will not rupture, leak, or deform due to pressure changes, such as refrigerant circulation, or high-temperature and high-pressure environments, during actual use. Only air conditioning pipes that pass the pressure test can proceed to subsequent assembly stages, ensuring the performance of the final product and user safety.
