Hi Trevor, I am evaluating a torispherical head with generalized corrosion and unknown weld examination using API 579 elastic analysis. Applying RSfa = 0.9 and weld efficiency = 0.7 reduces ASME II-D allowable stresses significantly. Since only the knuckle is weld-governed, should this reduction apply only to the weld band, or is this conservatism intentional in API 579?
I’m crazy about mold design and 3D printing. I love turning creative concepts into tangible items—mold design lets me nail the precise details that ensure products fit flawlessly, and 3D printing is ideal for fast design testing ahead of mass production. It’s so rewarding to see a rough sketch evolve from a digital model into an actual thing I can pick up.
