Products Information

Vertical duct seam closing machine Products Information

Generally,three different seams are common in the industry to connect the corners of the ducts:button lock seam,Pittsburgh seam and Duct seam.Button snap lock and Pittsburgh lock can be produced on the  lock forming machines.the Pittsburgh seam shows much better results and can also be used for a higher pressure.

Vertical duct  is what we highly recommend.Pittsburgh joint is commonly used to join the seams of metal ducts. Seam closing has traditionally been accomplished by manually hammering the margin of the seam against the duct wall (peening). Disadvantages of such peening include the time required and the almost intolerable noise produced.

the latest design in seaming technology is now available. At the Pittsburgh joint, the individual seams are called (pittsburgh lock) and standing seam(right angle flange). on a Pittsburgh joint, the operator pushes the standing seam into the Pittsburgh seam, fastens them to each other and closes the joint on a seam machine.
