Long Radius Bend (Curved Pipe)

Related Topics

Long radius bends feature bend radii R>10D. The central bend angle should not exceed 90 degrees (more information). See also prestressed long radius bend.

When used in Start-Base modules, these elements undergo automatic stability verification. Insufficient stability triggers error messages in the errors and warnings window. Additional stability analysis is available through Start-Elements using the bend stability function.
