Discussion Overview
The discussion revolves around the necessity of conducting a hydrostatic test when head pressure remains in a system. Participants explore the implications of pressure maintenance on testing requirements, particularly in the context of safety regulations and industry standards.
Discussion Character
- Debate/contested
- Technical explanation
Main Points Raised
- One participant questions whether a hydrostatic test is required if head pressure is still present in a system.
- Another participant requests additional context regarding the type of system and pressure ranges to provide better assistance.
- A participant shares past experience with a 3000psi operating system, suggesting that hydrostatic testing could be bypassed if head pressure is maintained, but becomes necessary once the pressure is released.
- There is mention of regulatory bodies such as OSHA and the importance of understanding applicable regulations for hydrostatic testing.
- Participants point out that testing requirements may vary based on industry specifications, legal requirements, and local building codes.
Areas of Agreement / Disagreement
Participants express differing views on the necessity of hydrostatic testing based on head pressure, indicating that the discussion remains unresolved with multiple competing perspectives on the requirements.
Contextual Notes
Participants highlight the dependence on specific regulations and standards, as well as the need for more detailed information about the system in question to determine testing requirements accurately.

Welcome to PF.
Could you please add more context to your question? What kind of system? What kind of pressure ranges? Is the fluid water or something else?
The more details you can give us, the better we can help you.

WOW so cool thank you for being there..........
In the past....using pressurized N2 on a 3000psi operating system, in a steel flask...the 5 year requirement to hydrostatic test the bottle could be ignored if the head pressure remained on the bottle. once the head pressure was let off the hydro is now require before refill..???
where do i go to find these requirements...Jack

Ah, that kind of hydro test. 
It depends on what regulations apply to your installation. Are you covered by OSHA in the US? Are you at a company or a university, and do they have a Health and Safety Department?

If this is in the US, pressure vessel testing requirements are specified in ASTM and local building codes.
