Sheet Metal Basics - Duct Construction- Joints & Seams fullofsheet - Mar 31, 2008 - 08:54 PM Post subject: Duct Construction- Joints & Seams
Attending Building Inspection Technology(BIT) program here in CA. Instructor hands out workbook final a couple of weeks ago. Out of 70 students, there are about about 20-30 of us going bonkers trying to fill-in a section on duct construction(the others could care less). Where can I find diagrams of: 1) machined seams, 2) Lap seams, 3) Joint connections? Also joint connections for round piping? Thanx and safe snipping!!!bordontn2 - Apr 01, 2008 - 02:40 PM Post subject:
