Bases: Profile

Representation of U/C shaped profiles.

For standard profiles, use the specific standard profile class like UNP. For example, 

unp_profile = UNP.UNP200

with_corrosion(corrosion: MM = 0) -> UNPProfile

Apply corrosion to the UNP-profile and return a new UNP-profile instance.

The name attribute of the new instance will be updated to reflect the total corrosion applied including any previous corrosion indicated in the original name.

Parameters:

  • corrosion (MM, default: 0 ) –

    Corrosion per side (default is 0).

Returns:

  • UNPProfile –

    A new UNP-profile instance with the applied corrosion.

Raises:

  • ValueError –

    If the profile has fully corroded.
