Description |
Name |
Element identifier. When checked, displays in 3D view |
Radius, R |
Mean bend radius. For Short, Long, or 3D bends, radius follows ASME B16.9-2012. For non-standard outside diameters (OD), R=OD (Short), R=1.5OD (Long), R=3OD (3D) |
Get properties from matching pipe |
Import properties from connected pipe |
Calculate weight automatically |
When enabled, calculates bend weight as torus volume using wall thickness from adjacent pipes |
Weight |
Bend weight including flanges, excluding insulation and content. Based on standard weights without overload factors. Content and insulation weights with overload factors auto-calculated from adjacent pipes |
Longitudinal Weld Joint Efficiency Factor, E |
Longitudinal weld joint efficiency factor. More... |
Manufacturing technology |
For ASME B31.1, ASME B31.3, DL/T 5366-2014, seamless pipes use Wl=1.0. Electric-welded pipe Wl values come from database. More... For GOST 32388-2013, pipe properties are sourced from different materials databases based on pipe type (seamless/welded). |
Material |
Material selection from materials database |
k-factor |
Flexibility factor for operating and test conditions. Minimum value: 1.0 Click |
SIF |
io - out-plane, ii - in-plane, it - torsion, ia - axial stress intensification factors. Minimum value: 1.0 Click |
Nominal bend wall thickness |
Nominal wall thickness for flexibility analysis, k-factor, and SIF calculations. Section modulus uses matching pipe thickness, not bend wall thickness |
Refresh SIF and k using FEA |
