API CORROSION/EROSION 4” Pipe (Inch Version) Material: Carbon Steel pipe, • 4” OD with variable schedules at Sch10 (0.156”), Sch80 (0.337”) and Sch160 (0.531”) • The pipe is a cut 180° segment with 12” axial length. • The ID has 3 machined steps; 0.156”, 0.337” and 0.531”, each step is 4” in axial length. Specifications: • Each wall thickness/step will contain 1 or 2 ID surface indications. • The indications include: • Corrosion • Random Pitting • Erosion • The indication depths will vary depending on the pipe wall thickness. • Typical depths range from 25%, 50% and 75% through wall. • The overall size of the surface indication will vary as to the depth of the indication. • The indication depth will be stated at the deepest point of each indication. Pitting indications will be based on the deepest pit. Final Documentation: • Includes C of C, “As Built” CAD and Measuring & Test Equipment Certificate • “As Built” CAD will show a general description of the flaws surface area.
