Issue of the length of the flange reinforcement fitting for the long diameter
Thread Content
When calculating the reinforcement for openings, it is necessary to enter the protrusion length of the reinforcement fitting; for WN flanges, this is naturally the length of the fitting itself. What about LWN flanges? It doesn’t seem right to enter the entire length of the joint; there should be a range within which stress concentration decreases in the flange diameter area, and this section cannot be used as a reinforcement element. Is there any calculation formula for determining the reinforcement length required for joints using such LWN flanges? How do people handle it in actual work?

Although it is not explicitly stated, the strength calculation for LWN flanges should be the same as that for WN flanges.
