胀接 is a widely used connection process in fields such as mechanical manufacturing, pressure vessels, heat exchangers, and its main purpose is to achieve a good sealing effect by making the pipe tightly connected with the tube plate or connecting part through plastic deformation. In many industrial equipment, sealing performance is directly related to the operation safety and efficiency of the equipment, therefore, studying how to improve the sealing performance of胀接 technology is of great significance.



Firstly,胀接 makes the pipe material undergo plastic deformation through mechanical means, thus tightly adhering to the inner wall of the connecting part and forming a tight metal contact. This contact not only reduces the gap but also increases the friction force of the contact surface, thereby effectively preventing medium leakage. Compared with simple welding or threaded connection,胀接 can achieve a more uniform pressure distribution, avoiding local stress concentration that leads to sealing failure.



Secondly, precise control of the胀接 process is crucial for improving sealing performance. Modern胀接 often adopts advanced technologies such as hydraulic胀接 or rubber胀接, which can accurately adjust the胀接 pressure and amount according to parameters such as material properties, pipe diameter, and connection requirements, thus ensuring that the connection surface reaches the best fit. This precise control not only improves the sealing performance but also extends the service life of the equipment.



Furthermore, reasonable胀接 design is also one of the key factors for improving sealing performance. At the design stage, factors such as the expansion coefficient of the material, working temperature, and internal pressure should be fully considered, and the appropriate胀接 form (such as single groove胀接, double groove胀接, or rolling groove胀接) should be selected. For example, in high temperature and high pressure environments, the double groove structure can effectively distribute stress and enhance the stability of the sealing.



In addition, the detection and maintenance after胀接 should not be ignored. Means such as ultrasonic detection, penetration testing, or air tightness testing can be used to detect and handle potential sealing defects in a timely manner. Regular maintenance and inspections help ensure that the胀接 structure maintains good sealing performance over a long period of time.



In summary,胀接 technology forms a tight contact through plastic deformation, and combined with precise process control, reasonable design, and effective detection means, it can significantly improve the sealing performance of the connection structure. Against the backdrop of increasingly pursuing efficiency, environmental protection, and safety in industrial production, the application prospects of胀接 technology will be even broader.
