What is the maximum pressure that a %99.9 pure tungsten tube can withstand?

SUMMARY

The maximum pressure that a 99.9% pure tungsten tube can withstand is determined by its ultimate tensile strength, which ranges from 80,000 to 500,000 psi based on various sources. The formula to calculate the maximum internal differential pressure is P = 2T·t/D, where T represents the tensile strength, t is the wall thickness, and D is the tube diameter. This calculation is crucial for applications requiring precise pressure tolerances in tungsten tubes.

PREREQUISITES
  • Understanding of tensile strength and its significance in materials science.
  • Familiarity with the formula for calculating internal pressure in cylindrical structures.
  • Knowledge of tungsten properties, specifically its purity levels and mechanical characteristics.
  • Basic mathematical skills for applying the formula P = 2T·t/D.
NEXT STEPS
  • Research the mechanical properties of tungsten, focusing on its tensile strength variations.
  • Study the application of the formula P = 2T·t/D in different engineering contexts.
  • Explore the effects of wall thickness and diameter on pressure tolerance in cylindrical tubes.
  • Investigate the manufacturing processes for high-purity tungsten tubes and their applications.
USEFUL FOR

I think the ultimate tensile strength of pure tungsten is about T = 100,000 to 500,000 psi, or 80,000 to 100,000 psi, depending on source.

If the tube diameter is D, and the wall thickness is t, then the maximum internal (differential) pressure is P = 2T·t/D.
