Product Description:

The SZY-400-A high-pressure hydraulic tube expanding machine is the third generation hydraulic tube expanding machine developed by our company, mainly composed of hydraulic system, high-pressure cylinder, high-pressure hose, tube expanding gun, expanding rod, control box and other components. Especially in deep hole expansion joints, it can accurately locate and meet the expansion joints of different materials and specifications of pipe holes. The expansion gun is lightweight, easy to operate, and suitable for single person operation. After expansion, the pipe hole is free of pollution, residue, and uniform expansion. In addition, it has the function of adjustable forced pressure relief in cases where the pipe hole is too small or the expansion rod is worn and difficult to pull out. Reducing losses during the production process has improved overall economic benefits.

The liquid bag expander can be divided into adhesive type and rubber sleeve type.Adhesive tube expander is suitable for adhesive expansion and strength expansion of ordinary materials. Suitable for pressures below 180Mpa, with a small expansion hole diameter ≥ 8mm. This tube expander has the advantages of easy installation and short customization time, but its disadvantage is that it has a low service life during strength expansion.The rubber sleeve expansion tube relies on its own sealing effect, which makes it more widely applicable and has better stability, especially suitable for high-strength expansion; The small expansion joint aperture must be ≥ 12mm, and the customization time is long.
