|Here are the purchasing tips for metal bellows expansion joints that most people are not aware of. Today, Xiong Sen will share with you the selection skills of metal bellows expansion joints. Please read on: When purchasing good metal bellows expansion joints, consider the comprehensive factors of the product, the medium characteristics, operating conditions, natural conditions of the installation site, diameter of the expansion joint, and larger displacement. If it is to compensate for displacement, installation deviation, and foundation settlement, reduce noise, and absorb vibration, it is recommended to use annular corrugated pipe metal bellows expansion joints. If it is for high pressure but infrequent displacement and vibration, spiral corrugated pipe metal bellows expansion joints should be selected. The nominal pressure of the metal bellows expansion joint should not be lower than the design pressure of the main pipeline. When used at a working temperature ≥ 100°C, the working pressure must be included in the temperature correction factor. The rated working pressure of the metal bellows expansion joint used for liquefied gas tanker loading and unloading must not be less than four times the maximum working pressure of the loading and unloading system. The length of the metal bellows expansion joint should be determined according to different purposes and relevant regulations. When selecting metal bellows expansion joints, confirm that the manufacturer's qualification, product quality certificate, and product usage instructions are complete. The above are the purchasing tips for metal bellows expansion joints. If you want to know more, please feel free to consult us.
