Use and maintenance of tube expanders

A pipe expander is a type of expansion tool used in the manufacturing and maintenance of various containers to expand the inner and outer diameters of pipes, so that the contact area between the pipes and the pipe plate is tightly connected, without water or air leakage, and can withstand certain pressure. Widely applicable for the manufacturing and maintenance of condensers, coolers, heat exchangers, boilers, and other pressure vessels in industries such as refrigeration, petrochemicals, power, shipbuilding, and metallurgy. Use a ratchet wrench (manual) or connector (electric) to cover the square head of the expansion rod, rotate clockwise to meet the process requirements, and then reverse the direction to exit. The electric expansion pipe machine has a set reverse device. When adjusting the expansion pipe, the required position and depth should be adjusted first, and then the expansion pipe should be completed according to the above steps. After use, clean and apply butter or engine oil to the reusable expander, put it into a toolbox, store it in a dry place, and avoid moisture and rust.

Use and maintenance of tube expanders

1. Use of tube expander: The main components of the tube expander have undergone heat treatment and have high hardness. When using, they must be placed flat with the expanded tube. During the tube expander process, even force should be applied to avoid improper use that may cause breakage of the expanding rod and bead.

2. Maintenance of the tube expander: Due to friction and heating with the tube, it can change the mechanical performance. The tube expander should be rotated and some lubricating oil should be added appropriately to extend its service life.

It has been widely used in various chemical, metallurgical, boiler and oil, refrigeration and other manufacturing sectors. Flaring machines are usually a combination of controllers and expander bodies, and are made from flexible hose coils.
