Adding |Pipe| to values in cells

Hi I have a column of barcodes. I need to get a formula or script to put |Pipes| as the before the 1st and after the last character in the cell.

E.g. barcode 123456789 should be converted to |123456789|

I then want all the individual barcodes to appear in 1 cell next to each other

E.g. in one cell |123456789|987654321|244346473|686541234|479854635|132498569| and so on.

Thanks in advance!
