Too much pressure!?!

[kennyd]

I think using the cylinder above its rated working pressure will cause premature failures. The working pressure is there for a reason.

A closed cylinder with a full bucket on it may not see the 3000# pressure of a pump attempting to move it against an immovable force. A cylinder with 2500# moving against an immovable force will have less internal stresses also. A bouncing bucket may not exhibit the same duration of forces as a constant pump exceeding the cylinder's working pressure.

Because a cylinder can withstand twice its working pressure for a specific interval does not mean it can be run above its working pressure on a daily basis.

I guess we will have to agree to disagree:thumbsup:

Appreciate the discussion and perspective on testing limits and working limits.

I don't think I'd be willing to go the pressure reducing valve route just for use with the 1 cylinder - more trouble than having to rebuild the cylinder every 3-4 years - IMO.

Just "go with the flow"... and pay close attention to operating the cylinder to avoid "dead heading" it and going to relief!

Thanks again - all.
