1 - reinforcement pad, 2 - matching pipe, 3 - header pipe
A stub-in is a T-shaped joint with the same cross-section as adjoining elements. Branch and header axes are perpendicular. All properties are automatically determined from adjoining elements.

Branch not perpendicular to header |
If checked, branch and header joint angle is not checked and analysis is header as for a slanted stub-in (according to GOST R 55596-2013 and RD 10-249-98). If not checked, branch and header joint is checked and if it is not equal to 90 degrees, an error is displayed. |

For ASME B31.1, ASME B31.3, DL/T 5366-2014 seamless pipe will always use Wl=1.0. For electric-welded pipe Wl will be specified from database. More... When using GOST 32388-2013, pipe physical properties are taken from different materials databases depending on pipe type (seamless/welded). |
