Discussion Overview

The discussion revolves around the search for glassware capable of withstanding very high pressure, specifically in the context of superheating substances that generate significant pressure. Participants explore the limitations of glass and suggest alternatives.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about suitable glassware for high pressure, prompting others to clarify what constitutes "very high" pressure.
  • Another participant notes that pristine glassware is typically rated for around 40 psi, emphasizing the importance of avoiding scratches.
  • A specific pressure of 22242 kPa (approximately 220 atmospheres) is mentioned, raising skepticism about the feasibility of using glass for such conditions.
  • One participant suggests that a DOT tank might be a more appropriate solution than glass for extremely high pressures.
  • Another participant indicates that the application of the glassware is crucial for providing recommendations.
  • A later reply expresses doubt about the suitability of glass for superheating substances due to the risk of shattering under high temperatures and pressures.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of using glassware for very high pressures, with some suggesting alternatives and others questioning the practicality of the request. The discussion remains unresolved regarding the best material for the intended application.

Contextual Notes

Participants highlight limitations related to the pressure ratings of glass and the potential for shattering under high temperatures, but do not resolve the specific requirements for the application.

Hey all, I was just wondering if anyone can suggest a kind of glasswear that can withstand very high pressure.

thanks all:)

How high is 'very high'? Pristine glassware with ground glass joints is only good to roughly 40 psi... NO SCRATCHES!

Glassware in steel cyls or polymeric cyls can go much higher. Glass lined pressure reactors can go very high, for example.
 
something that can withstand like 22242 kPa of pressure

:rolleyes: You do realize what you're saying, right? You want a... glass vessel... that can withstand over two hundred atmospheres of pressure.

Good luck. You might want to try a DOT tank instead.

well it doesn't have to be glassware.
 
What are you using the glass for? It might help us give you a recommendation.
 
i 'm super heating a substance that when heated high tempetures it creates a huge amount of pressure. i don't think glass is the best use, cause it will shatter at a high tempeture and pressure.
