Some necessary words are in the word bank. Calculate the following dimensions. (Ignore the thickness of the sheet metal for now.) 1. pipe diameter 80 mm; insulation thickness 30 mm Calculate the outer diameter.  80 + 2x 30 = 140 mm 2. outer overall diameter 220 mm; insulation thickness 60 mm Calculate the pipe diameter.  220 – 2x 60 = 100 mm 3. pipe diameter 150 mm; outer diameter 250 mm Calculate the insulation thickness.  (250 – 150)/2 = 50 mm Mosaic The shaped but unbent state of a sheet metal cladding is called “development”.
