The tool stalls or slows sharply during rolling
How to fix it
Φ45–Φ159 mm thick-wall tubes: DZ-C large-tube electric tube rollers
High torque or hazardous areas: HD series hydraulic tube rollers
Rolling and flaring in one pass: F series flaring expanders
Use a balancing arm or reaction arm to take the reaction torque
What to send us
Tube material, OD and wall thickness (mm or BWG)
Tubesheet thickness and hole size
Number of tubes; site conditions (power or air supply, hazardous area)
