Understanding the Need for Flange Analysis Software

Flanges must be carefully designed to prevent leakage, garantir a segurança, and comply with international codes such as ASME Section VIII Div. 1 & 2, EN 1591-1, e outros. Traditional hand calculations, while still relevant, often fall short when assessing complex load conditions, expansão térmica, comportamento da junta, or non-standard designs. This is where dedicated flange analysis software becomes indispensable.
