[QGIS-ZA-user] links between nodes as feature lines, data from CSV files

Hello,
The attached COORD columns are all in SID:2053 (metres) I can easily import the MANHOLEDATA and display as nodes:
COORD1 column =X, COORD2 column = Y

But how do I create line features using the PIPEDATA txt(csv)?

PIPEDATA has two node columns: "Upstream_MH","Downstream_MH"
A line feature is needed between those nodes, the coordinates provided by MANHOLEDATA.

Start of line, PIPEDATA: Upstream_MH = MANHOLEDATA: Manhole_No 

End of line, PIPEDATA: Downstream_MH = MANHOLEDATA: Manhole_No

Note:
Even though the PIPEDATA includes COORD columns, these need to be ignored - only use the node positions provided by MANHOLEDATA.

Thanks for reading and helping,

Kevin.
