Need to build an underwater housing for camera

[Barry Geer]

will an aluminum tube 127mm in diameter, 3.5mm wall thickness, enclosed on either end by 12mm thick disks with o-rings be able to with stand 15bar of pressure. Its for an underwater camera housing.

What is your question? What part are you having trouble on?

 

[Barry Geer]

Will a vessel of those constraints be able to withstand 15bar of pressure?

How long is the tube?

 

[Barry Geer]

Hi there..its 750mm long

Hi there..its 750mm long

Why so long? What kind of camera is it? Is there a reason you can't use a commercially-available underwater camera housing?

 

[Barry Geer]

This section is to house batteries for the camera and motors. Its part of an ROV that will be going down to 100m.

Seeing as you can't do the engineering yourself why not just use pipe and fittings with the appropriate pressure ratings?

 

[Barry Geer]

Hi Billy
Thanks..but we struggling to get that info. Very frustrating!

 

[billy_joule]

You have all the info you need. Call your local pipe supplier, tell the sales engineer you want pipe rated for 15 bar vacuum with X OD and X length, along with a blank cap and a site glass cap. I don't know if they'll be flanged or threaded but he will. If your lucky, he'll price it over the phone andemail you a formal quote within an hour.

Thanks Billy..will do that..appreciate the responses!
