Type

• Butt Weld - SIF depends on mismatch (δ) and wall thickness (t)

δ – mismatch, t – pipe wall thickness

• Tapered Transition (butt weld) - SIF depends on Do, δ, and t

δ – mismatch, t – pipe wall thickness, D – diameter of pipe with thinnest wall

• Threaded Joint or Threaded Flange - SIF = 2.3

• Single-Welded Slip-On Flange - SIF = 1.3

• Double-Welded Slip-On Flange - SIF = 1.2

• Lap Joint Flange - SIF = 1.6

• Fillet Welded Joint or Socket Welded Flange (Unfinished) - SIF = 2.1

• Fillet Welded Joint or Socket Welded Flange (Finished) - SIF = 1.3
