Scuba concave convex

[Enkey]

Hola

Todos los tanques scuba que conozco tienen una base cóncava, pero al mirar una tienda en línea, vi que le ofrecían la opción en convexo, ¿alguien sabe las ventajas o desventajas del tanque scuba cóncavo o convexo?

Saludos

I think you have that backwards. My SCBA is convex, I have never seen one that is concave. I think if the bottom was concave they would stand up on their own and that might be better...

Hi 

You are absolutely right I put it upside down, but I cannot find the difference between one and the other

Look at a champagne bottle, bottom caves in to better withstand internal pressure.

Some SCUBA 200 and 230 bar bottles comes with a flat bottom which nessitates more material not to deform under pressure and in water the added weight is not a problem. But we landcrabs who has to haul our air around hates added weight.

So a pressure wessel with (outwards) domed ends gives the most strength for any given material = light as possible.
