Wall thickness [WALL]

Specification of pipe wall-thickness along pipeline axis (Input Table)

Table description:

Through the input data table WALL the nominal wall- thickness with minimum manufacturing tolerance and corrosion allowance along the pipeline axis is provided to the pipe model. The wall thickness data are provided as a polygon data line projected on one of the available coordinate axes by means of reference points.

A wall thickness is attached to each element by relating the coordinate of the centre-point of the element to the polygon data line and interpolating the wall thickness values at the adjacent reference points.

Coordinate data of successive data table lines shall have increasing values.

Info As the analysis method is based on thin-walled cross-sections the DOUT/WALL ratio shall be within reasonable values, ranging from 20 to 200.
