Heat exchanger gas liquid tube expansion machine

Heat exchanger gas liquid tube expansion machine

Function

Heat exchanger gas liquid tube expansion machine is a special hydraulic expansion equipment for the expansion and tight connection of tubes and tube plates in the manufacture of heat exchangers, condensers, high-pressure heaters and other equipment. The use of hydraulic expansion technology has the advantages of low manufacturing cost, light labor intensity, short manufacturing cycle, uniform and reliable expansion quality. Hydraulic expansion joint technology has been widely used in the manufacturing of heat exchangers in petrochemical, electric power, boiler, nuclear power, refrigeration and other fields, greatly improving the quality and production efficiency of domestic heat exchanger equipment.

Heat exchanger gas liquid tube expansion machine is a new generation of expansion equipment developed by our company, driven by compressed air, specially used for ultra-high pressure expansion of ultra-thick pipe walls. The application of this equipment can be a variety of specifications, a variety of materials of the heat exchange pipe for reliable expansion. The heat exchanger manufactured by the technique has the advantages of uniform and reliable expansion quality, long service life and low failure rate. Moreover, the expansion operation is simple, the expansion speed is fast, the manufacturing or maintenance time is greatly shortened, the production loss of chemical equipment is reduced, and the economic benefits are very high. As the earliest enterprise committed to the research and development of hydraulic expansion technology in China, after more than 10 years of continuous improvement, the products are leading in China.

Characteristics

1. The 25-400mm thickness tube plate can be uniformly expanded at one time with full thickness;

2. The full thickness expansion can be applied to intermediate tubeplate or multi-tubeplate heat exchangers of any depth;

3. The full thickness expansion can be applied to intermediate tubeplate or multi-tubeplate heat exchangers of any depth;

4. The residual stress of the device after expansion is low, which is not easy to produce gap corrosion;

5. The axial direction of the heat exchanger after expansion does not stretch and slightly shrinks, which is conducive to reducing operating noise;

6. The error of the inner hole of the pipe is large, and the diameter of the expansion head can be adjusted appropriately on site;

7. No pollution at the expansion joint, the first expansion after welding is not affected;

8. The edge of the heat exchanger with the tube box can be directly expanded, which is very convenient;

9. One person can continuously expand, can expand 5-7 tube heads per minute;

10. The comprehensive economic benefits have been greatly improved.

11. Can expand copper, carbon steel, stainless steel, duplex steel, titanium alloy, composite materials, etc.;

12. High pressure imported rubber expansion bag has strong fatigue resistance, and the average service life is more than 100 times/branch;

13. Integrated design of vulnerable parts - expansion rod, easy to replace;

14. Low labor intensity, high production efficiency, each equipment can expand more than 2000 pipe holes per shift.
