The introduction of Boarding Actions as a 40k game mode inspired several sets of ship-corridor terrain for printing, you could probably just buy the STLs for any of those and rescale them. But at the end of the day, Space Hulks aren't necessarily made up of imperial vessels at all, so there's no set aesthetic you need to match. Why aren't you just grabbing cheap model kits and junk from goodwill and kitbashing your hallways, then spraying them a black and drybrush them silver? Some of science fiction's most beloved designs are just a bunch of scrap parts hot-glued together and sprayed gray, just look at star wars.
Alternatively, just get some of the Joytoy diorama sets and use them to build your own hallways. They're modular, you can build them into whatever you want.
