Round Duct Seaming Machine
Select round seam-closing capacity by diameter, prepared-joint length and material together.
- Diameter
- 110–2000 mm
- Length limit
- 1500 mm
- Sheet reference
- 0.4–1.2 mm
Size the whole cylindrical workpiece
| Dimension | Supplied reference | Buyer check |
|---|---|---|
| Diameter | 110–2000 mm | Actual tube support and seam position |
| Processing length | Maximum 1500 mm | Longest prepared longitudinal joint |
| Sheet thickness | 0.4–1.2 mm | Grade and profile compatibility |
Support is part of the closing process
Straight longitudinal joint
Model 1.2×1500 closes a prepared seam on round duct. The support arrangement must suit the cylinder and keep the joint aligned through its length.
A helical spiral seam is a different forming route. Do not use diameter alone to assign that work to this closer.

The source lists 7 m/min processing speed and 1.5 kW at 380 V / 50 Hz / 3P. Confirm grade, seam and full workpiece handling rather than extrapolating speed to dispatched ducts.
Measure accepted tubes, not only the closing movement
- 01
Roll and prepare
Form the tube and mating edges.
- 02
Locate seam
Check support, alignment and access.
- 03
Close length
Run the representative complete joint.
- 04
Release and inspect
Check closure, dimensions and required tests.
Questions to settle before ordering
Does it close a spiral seam?
The reference describes straight longitudinal seams on prepared round duct.
Can any 2000 mm cylinder be processed?
Confirm grade, thickness, length, joint and support; the diameter maximum alone is incomplete.
What happens above 1500 mm length?
Obtain a separately confirmed arrangement; do not assume the listed maximum covers longer work.
Is 7 m/min finished output?
Include loading, alignment, removal and inspection.
What should I send?
Tube diameter, grade/thickness, seam sample, length range and utilities.
