Stress Indices for Non-Radial Branch Connections for Piping

Sajish, S.D. / Sati, Bhuwan Chandra / Jalaldeen, S. / Selvaraj, P. / Chellapandi, P.

Procedure for determining the stress indices for non radial branch connections is discussed. A typical non radial branch connection, commonly used in the piping system of FRFCF is modeled and analyzed using CAST-3M for calculation various stress indices for the connection. B2 Stress indices for the branch connection for in plane bending and out of plane bending is arrived at based on nonlinear finite element analysis and limit load approach. K2 factor is determined using Peterson's curve, based on the curvature at the junction of run pipe and branch connection. Stress index C2 and the stress intensification factor i are determined by employing the relations of these factors with other stress indices.
