List of materials for pipe. All the possible combinations material/diameter are listed in this table. _displayname_fr, _displayname_de and _displayname_en are automatically generated by rules on insert and update. They are meant to be used in QGIS for the combo box of pipe.fk_material.

Remark: The pipe industry maintains two different ways to refer to the dimension of a pipe: - Nominal Diameter (DN) which is commonly used for steel/iron, plastic pipes. Both diameter_inner and diameter_outer refer to the tube. - Outer Diameter(OD) is taken into consideration for the insulation of the pre-insulated metal, flexible metal and plastic pipes (from 1 to 3 are maintained in pipe_section_pipe_od table)

The DN is a number that represents the approximate interior diameter, in mm. The value represents only an approximation of the pipe diameter so that engineers use a nice round number; the actual value is usually off by a few mm. So, when referring simply to the diameter, it is assumed that for plastic pipes you’re referring to the outer one, and for iron/steel and GRP ones to the approximate interior one - Nominal Diameter (DN).
