Nauts could do with your help
I am currently working at a petro chemical site. There is a big nitrogen tank there that groans and creaks…it’s fantastic, almost like it is alive
I need sounds like that. The closest I’ve found are these

This is from meagre searching from my phone as I’ll not be home for at least another week, would love help finding similar sounds
Many thanks x
Try getting hold of a Zoom recorder and a mic and capture the sound. It’s a lot of fun, both the recording and experimenting with back home.
Plus they will be your own unique samples.
Try to sample
Far too noisy there for recording sadly
Contact microphones?
Look for samples involving dry ice and cymbals or any other metal. Commonly used technique in foley and sound design.
Thanks Brute
I must also say we’re not allowed any form of electronic device on site incase we blow it up
110v tools from a diesel generator are fine though 
Seems like a 110 V diesel powered field recorder is the way to go then!
Haha
I had a job once at a factory too with all these sweet metal pipes and steam and noises. Sometimes there’s even some rhythmic stuff going on. There’s definitely a beauty to such a soundscape. They had a similar policy about electronic devices in certain areas.
I don’t know how strict they are at your place, but I’ve seen people walk around with their phones in these areas without anybody lifting an eyebrow. Had a chat with a superior about recording some of the noises and we jokingly came to the conclusion that as long as the recording device is outside of the designated zone, I can use a veeeeery long XLR cable and a microphone to record the stuff. As long as there’s only a very small signal-voltage going in and out of the zone it’s fine.
So I’m neither confirming nor denying that I recorded some samples, but since you mentioned noise – I was able to cut out lots of unwanted noise with filters or gates on my samples.
