Hi All.
1. Does everyone else keep getting spam messages from
Scott Waters?
2. I have finalised my HP air system. Ive probably
made a meal out of something relativly simple but i havent ever
built a HP system like this before so have had to figure
it all out.
The system will be designed to route as per K350 design but use
swagelok fittings and run at higher pressure. The
system is designed to opperate at a max pressure of 1000 psi
but will run normally at lower. Most of the system will be 1/4
inch pipe, with just the variable tank inlet\vent part 1/2
Inch.
The limitation on the design is the worcester ptfe sealed ball
valves which have a maximum working pressure of 1000psi
(69bar).
I have 2 last questions.
1. I have decided to use worchester ball valves (466TSE
ptfe sealed) instead of the diaphragm valves or even needle
valves. Do you think this will be ok?
2. Does anyone have any suggestions for the thickness for
my 300bar manifold.
I am going to make a 4300psi (300bar) stainless manifold to
accept the tanks.
The manifold will have 2 x standard scuba quick release high
pressure hose fittings. Like you would use for a BCD or gauge
off your 1st stage. This means i can run 2 tanks to the system
but be able to get them on and off easily and quickly.
There will be a 300 bar gauge attached to the top of the
manifold to measure manifold inlet pressure, a manual relief valve
off another port and then the outlet which will go to a 300bar -
70bar pressure reducing regulator with inline gauge to measure
system pressure.
Emile says that the HP port on a normal 1st stage does not
give a lot of flow, so i am going to just run it and see if its
enough. If not, i can pipe the manifold directly to the
tanks.
The idea with this is that 1, the 2 x tanks can come off easily
and 2, i have adjustable high pressure outlet.
Sorry, after all that, the question is. Any suggestions
for thickness of the manifold to hold at 300 bar? I think i
might go to my local dive shop and measure the thickness of their
filling station manifolds. hmm, good idea.
Thanks as always,
regards
James
