During WW2 Kaiser built a refractory plant at Moss Landing. Ca.  It used sea water pumped in 51" wooden pipes.https://www.waterboards.ca.gov/centralcoast/board_info/agendas/2015/november/item10/item10_stfrpt.pdf
The article doesn't say wood pipe but I've personally examined it.  Here's also a film from 1951 that shows the process and halfway though the film is a nice view of an SP hopper. https://californiarevealed.org/islandora/object/cavpp%3A11383
