What are the excellent characteristics of the vertical tube expander and the precautions for the use of the horizontal tube expander

The vertical tube expander has a variety of functions, which can meet our needs and bring convenience to us. The following mainly introduces the features of the down pipe expander:

1. The main engine and head of the tube expander are portable and can be operated on site, which greatly reduces the burden of operators and improves work efficiency. It is suitable for single person continuous operation of expanding joint.

2. The expanding force of the tube expander is uniform, which supports the expansion before welding, and can uniformly expand the tube sheet at one time.

3. High quality components are used during the tube expander period, so there will be no crash and black screen on site.

4. When the tube expander is expanded, it will not affect the expanded pipes around, and the stress on the tube bundle is small, and the end plate will not be damaged.

5. The equipment level has no axial expansion and contraction, which can reduce the operation noise.

6. After the expansion, the inner surface of the tube end is smooth, and the expansion joint along the end plate is uniform, and there is no mechanical damage.

To sum up, the vertical tube expander has many excellent characteristics, which can meet our needs and greatly improve the work efficiency. In order to ensure the normal operation of the equipment, we should standardize the operation and regular maintenance, so as to extend the service life.

With the continuous progress of science and technology, the horizontal tube expander is used more and more widely. In order to effectively ensure the normal operation of the equipment, the following is a detailed introduction to the precautions for the use and storage of the equipment:

When the horizontal tube expander is used, the ratchet wrench or connector should be set on the square head of the expanding rod, and then it should be rotated clockwise. When the required process requirements are met, it can be reversed and withdrawn. The electric tube expander is equipped with a reversing device. When expanding the tube with adjustment, the required position and depth can be set first, and then the tube can be expanded according to the above steps. After the end of use, the parts of the pipe expander should be cleaned, and the parts should be coated with butter or oil, and put into the toolbox and stored in a dry place to avoid the equipment from being affected by moisture and rust.

When the horizontal expansion bar is placed improperly, the tube should be avoided due to its high hardness. The friction heating of equipment will change the mechanical properties, so we should use the expander alternately and add some lubricating oil appropriately, so as to prolong the overall service life.
