Reply:It's for pneumatic material conveying lines...wood material typically. This one is for a pulp mill. Actually, we built 10 of these this weekend...most of the pieces were formed and half or more of the transitions were already done as well. They have to be hardsurfaced on the inside seams. About 6 hours of welding on each. The 0.52 metal core and a 6oo amp machine help it along.
Reply:Backs are formed in the press brake ...the mild steel parts and flatbars are rolled
