NOTES:
1. Wall thickness is the nominal wall thickness of the thinner of
components joined by butt weld.
2. Height: For "Normal Service" and "Severe Cyclic" conditions, use the
listed value. For "Category D Fluid Service," use twice the listed value.
Measure from surfaces of adjacent components. The lesser of the two
measurements, in any plane through the weld, shall not exceed the applicable
value at right. Weld metal shall merge smoothly into component surfaces.
