D-type large deflection pipe expander is mainly composed of bellows, pipes, flanges and fasteners. Among them, the bellows is the core component of the telescopic, which is made of high-strength and high-elastic materials, with good elasticity and corrosion resistance. The coupling is used to connect the piping system, and the flange is convenient for connecting and fixing the piping. Fasteners play the role of fixing and sealing, ensuring the stable operation of the expander in the piping system.
The working principle of the D-type large deflection pipe expander is mainly based on the expansion and contraction deformation of the bellows. When the pipeline system is affected by temperature changes, pressure fluctuations and other factors, the expander can expand and deform within a certain range to absorb and mitigate these effects, so as to protect the safe operation of the pipeline.
As an important pipeline connection equipment, D-type large deflection pipeline expander plays an important role in ensuring the safe operation of pipeline system. Its unique structural design and excellent working performance make it widely used in various industrial piping systems. With the progress of science and technology and the continuous improvement of engineering needs, the D-type large deflection pipeline expander will be continuously optimized and improved to provide a more reliable guarantee for the safe and stable operation of the pipeline system.
