How to match a flange to a terminal box
Matching flanges correctly involves several considerations: Flange Type – Weld neck, slip-on, blind, threaded, or lap joint. Learn the correct methods for making flange connections and avoid common mistakes with bolts and gaskets. The flange can withstand high pressure and temperature, so they have different pressure and temperature ratings for different. A pipe "flange" is a ring of metal, usually welded to the end of a pipe, with holes drilled in it parallel to the pipe centerline to accept several bolts: Flange joints are made pressure-tight by inserting a donut-shaped gasket between the flange pairs prior to tightening the bolts. I want to make a box (a base & 4 sides), with nice walls and the flange edges that come together equally, so I can run a fillet weld down the seam. The flanges mate at their inside edges, no overlaps, gaps, or anything, just inside edge to inside edge. It is also important to pay attention to the position of the loose flange/backing.
