Sweco Fab., a division of PT&P custom designed multiple duct work transition pieces for polyethylene dust at a chemical plant in Louisiana. The units are fabricated from carbon steel and include a 3- coat paint system on the outside, with a light grey finish. The dimensions are 15” length, 13-1/2” SQ flange end, and 10” NPS at the other end. Transition pieces are normally used to join duct work of dissimilar cross-sections and sizes. Media passing through the transition piece can be air, liquid, gasses, dust, dirt, chemicals, etc. Prior to shipment, each of the units underwent quality control inspections including 100% dye-penetrant examination.
