Layout and Fitting II
Advanced layout through a winter in Ironbridge Industrial's fabrication shop in Port Allen, Louisiana: pattern development by parallel lines, radial lines and triangulation, pipe cuts and segmented elbows, right, truncated and eccentric cones, square-to-round transitions, tees and laterals, round inlets through cones, nozzle openings on shells and heads, head types and inspection, fitting heads and cones to shells, and templates and CNC cutting files, ending with a capstone that lays out and fits a column section with a cone and a nozzle set.

What you'll learn
- Explain which surfaces can be developed, choose parallel-line, radial-line or triangulation development, find true lengths, and develop rolled parts on the mean line
- Develop pipe cuts and segmented elbows by the parallel-line method and work out gore throat, heel and centerline lengths
- Develop right cones by the radial-line method, split large cones along elements and form and check them
- Develop truncated cones from their imaginary apex and eccentric cones by triangulation, and check triangulated patterns
- Triangulate square-to-round, rectangle-to-round and offset transitions and form them by brake and roll
- Develop branch and header patterns for tees and laterals from the line of intersection
- Find the line of intersection between a cylinder and a cone with cutting planes and lay out the opening on the cone's pattern
- Lay out radial, hillside and tangential nozzle openings and necks on flat shell plate and on formed heads
- Describe head types and proportions, order and inspect heads, and find the height and slope of a head at any radius
- Fit heads and cones to shells by matching circumferences, spreading offset and checking square and level
- Make and mark templates, prepare CNC files with segment tolerance and kerf compensation, nest parts and check files before cutting
- Take a vessel section with a cone and nozzles from drawing to a recorded fit-up
