Building a Transparent Pressurize cylinder

[Shahid4u]

Hi,

I am looking for building a Transparent Pressurize cylinder to withstand a pressure of 300 psi. I am bit confused of Using either Poly carbonate or Acrylic as the material. Can anyone help me on this.

Instructions are somewhere on the board. Use “search” and dig around. I remember this being done before.

Why 300psi? That is over 20 ATA (2000m)!

Does the cylinder need to be transparent, or just a window looking onto a cylinder?

Filter containers like this are rated with a working pressure of 250psi:
10 Inch Clear Filter Housing Frp Vessel Transparent Active Carbon Filter Cylinder - Buy Frp Vessel,Active Carbon Filter Cylinder,Clear Filter Housing Product on Alibaba.com


If you can use something smaller, you can get glass tubing like this Hi-Pressure Clear Tubular Glass 1″ OD | Gage Glass that's rated to 300psi.

Google for "transparent pressure vessel" and you'll find tons of businesses manufacturing and selling scientific equipment like this.

I have noticed gravity getting stronger as I get older but had not noticed the atmosphere getting a lot heavier. Did you mean 200 meters.

Oops. Yes. My bad. What is a zero among friends?

SAFETY WARNING

Be very cautious when using plastic housings rated for internal water pressure. The issue is failure mode. A crack will drop the pressure instantly when the system contains all water (virtually no gas). Plastic pressure vessels containing gas will explode on failure due to expansion and creates little bits of shrapnel.

This is why OSHA (Occupational Health and Safety Administration in the US) prohibits using PVC pipe for air service.

The safe solution is to fill the filter housing with water and pressurize it with a small hand-operated water pump, NOT with air pressure.

Plastics used on internally pressurized systems that are designed for gas service have much greater safety margins and quality requirements than for water.

Gravity sucks.
