Custom Bend





Element name. If checked then it shown in 3D view

Radius, R

Bend average radius. If Short, Long, 3D bend specified, then radius got according to ASME B16.9-2012. If outside diameter (OD) is not equal to values in ASME B16.9-2012, then R=OD for short, R=1.5OD for long and R=3OD for 3D bends

Calculate weight automatically

If selected, reducer weight is calculated automatically as torus volume with wall thickness equal to that of adjoining pipes


Bend weight (with flanges) without insulation and product. Set according to standards without taking into account the overload factor. Product and insulation weight with corresponding overload factors are calculated automatically based on adjoining pipes

Longitudinal Weld Joint Efficiency Factor, E

Longitudinal weld joint efficiency factor, E. More...

Manufacturing technology

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).


Material from materials database


Flexibility factor for operation and test state. Not less than 1

If you push the button - the k-factor will be calculated as for pipe bend per ASME code


io - out-plane, ii - in-plane, it - torsion, ia - axial stress intensification factors. Not less than 1

If you push the button - the SIF will be calculated as for pipe bend per ASME code

Nominal bend wall thickness

Nominal wall thickness. Used for flexibility analysis, k-factor, SIF calculation. The moment of resistance is calculated using matching pipe thickness, not bend wall thickness
