Tube expander technology principle
The hydraulic expander used in the hydraulic expansion joint technology of domestic tube expander is composed of high-strength alloy steel core rod and high-pressure imported elastic rubber. It is designed in an integrated design and can withstand high pressure without the use of seals. It is easy to use and has high work efficiency. , the working principle is as shown:
It uses the high-pressure hydraulic pressure provided by the expander to apply the radial pressure generated by the high-pressure resistant elastic rubber body to expand the pipe to the tube sheet. When the ultra-high hydraulic pressure enters the high-pressure resistant elastic rubber body through the high-strength alloy core rod. The high-pressure resistant elastic rubber body generates a radial pressure sufficient to plastically deform the tube material to achieve expansion between the tube and the tube sheet.
