Tube expanders are widely used core equipment in HVAC systems, boiler manufacturing, heat exchanger production and refrigeration industries. Their core function is to expand tube ends through mechanical rolling or hydraulic pressure, enabling tight and seamless connection between tubes and tube sheets. In actual industrial operation, there is an unbreakable operating standard: only soft-state...

In industrial manufacturing, pipeline maintenance and HVAC engineering, tube expansion is a fundamental and frequent processing procedure. Traditional fixed tube expanders are bulky, immobile and costly, which greatly limits construction flexibility and increases operational costs. In contrast, modern handheld tube expanders stand out in the industry due to their outstanding economic efficiency...
