What parts do I need to buy to replace drain situation?

What parts do I need to replace this 40mm setup? I'm thinking of cutting the pipe to the right and replace the rotten part with a flexible connection. The T goes into a ceramic drain pipe.

Flexible double waste adapter
Length of 40mm solvent weld pipe
2x 40mm bends
1x 40mm socket
Solvent glue
