How to Miter Pipeline and Fabrication Fittings

https://schofield-enterprise.myshopify.com I remember the first time I was taught how to miter fittings. We where welding some 12” .375 wall pipeline and I got asked to go build different degrees out of our 90 degree fittings. I had no clue how to do it. In this video I’m going to help you guys with the calculations on building these different degree fittings. All you need to remember is the formula. I.R divided by degree of fitting being used. Multiplied by wanted degree. Then O.R. Divided by degree of fitting being used multiplied by wanted degree.
