The real cheap ones go to 25Bar mate not psi - plenty of pressure

50% above rated pressure.

 

[angellonewolf]

25 psi is about the bottom of car tyre pressure range, so that would be no good!. 150% of SWL is normal.

swl ?

50% above rated pressure.

as above ?

The real cheap ones go to 25Bar mate not psi - plenty of pressure

will cheak on this


im sure my old compresser is 8 bar will have to cheak

 

[Seadog]

SWL - Standard Working Load.
Used for cranes and gantries.

 

[mtt.tr]

SWL - Safe Working Load.
Used for cranes and gantries.

Slight correction

There should be a plate with the info stamped on it welded to the tank.

So that then is 11 bar so needs to be tested at 20 bar ?

 

[Seadog]

No, 16.5 bar.

 

[angellonewolf]

so a 25 bar tester would do then

Yes

Don't forget to remove all the fittings and bung up the holes with with BSP black iron bungs (from your local plumbers merchant etc)
Fill the tank from the tap, using that pump to fill it might take days and your arms will still fall off before it's full.

 

[Seadog]

You don't have to get every last cc of air out, but the more you do the less pumping.

Don’t stand in front of any plugs when testing. If one fails, it will be ejected like a bullet. Covered with something that would absorb the energy of any flying plug would be good

That 240psi test pressure would appear to be 50% above the safety valve (pressure relief) blow-off pressure.

I've got the plugs that I was going to test the old tank that failed so hope most of them I will have fitting for

I'm thinking find the top most hole open the 2nd Highest hole fill using water pipe and plug up as I go and when no water is going in start my son pumping

And I will stand to the side and should a few towels I can throw over

 

[angellonewolf]

Ok how to test

It's up to 17 bar now what

 

[angellonewolf]

I had a few leaks through blanks and have had to Reseat 3 of them but no water at this moment is coming out in thr walls of the tank

Just done the last one and leaving it for a bit see what happens

 

[angellonewolf]

There will be a maximum pressure-loss limit, in a prescribed time period, to pass the test. If it passes , empty the water and good to go with air, in order to test the safety relief valve is operating correctly. If that is OK, it should be good until the next test - providing the tank is drained as per operating instructions (or according to good operating practice).

and whats that

 

[angellonewolf]

Update now looks like this

got a bung in the end to get

And wire up the electrics


And need to know how to increase and decrease to air pressure in it


Before the unit stops I'm assuming it's in the black switched unit at the end there is a screw on top of a spring thing in the block

 

[dave h 2]

Just like the Tiger unit behind it, why the need to ask?
