Round Elbows

ATS Part Type #20

Our standard radius 90^o sweep elbows have a centerline (CL) radii equal to 1.5 times the nominal diameter. Extensions at each end of the elbow facilitate the use of ATS H-Collars (or ATS internal slip collars) for joining purposes.

If the elbow you require exceeds the size range, requires a shorter turning radius, or is otherwise unavailable as a standard radius sweep elbow, refer to ATS part types listed below:

• #19–Round Special Radius Sweep Elbow
• #21–Round 90° Short Radius Sweep Elbow
• #22–Round 90° 2 Gore Mitered Elbow
• #23–Round 90° Standard Radius 3 Gore
• #24–Round 90° 3 Gore Mitered Elbow
• #25–Round 90° 5 Gore Mitered Elbow
• #26–Round 60° Standard Radius Sweep Elbow
• #27–Round Standard Radius Sweep Elbow (degree specified)
• #28–Round Mitered Elbow (degree specified)
• #30–Round 45° Sweep Elbow
• #32–Round 45° 2 Gore Mitered Elbow Mitered Elbow
• #33–Round 45° 3 Gore Mitered Elbow
• #35–Round 30° Sweep Elbow
