The Pipe Lock Seamer is a pneumatic pipe seamer that closes the lock seam on round pipes. No more hammering. It seams internal, outward and middle twist locks on pipe diameters from 150 mm up to 1000 mm, and a 120 cm pipe takes about 3 seconds. Use it for ventilation pipes and solar energy systems, where a neat, evenly closed seam matters. A foot pedal runs pinching and rotation, which leaves one of the operator’s hands free to guide the pipe (catalogue: Pipe Lock Seamer, LSM 15).

Where It Fits in Your Duct Line
The pipe lock seamer is the last forming step for round pipe with a longitudinal lock seam. The pipe lock edge can be rolled on the Pittsburgh Lock Former, which has a pipe lock function, and the sheet is rolled into a cylinder on a slip roll (see Hand Operated Machines). The LSM 15 then closes the seam. For spiral-seamed round duct, see the Spiral Duct Machine. Other round fittings are on the Round & Spiral Duct page, and the full sequence is on the HVAC Duct Production Line page.
