Frequently Asked Questions

Q1: How does the 3000 Mpa compressive strength impact performance?
A1: The 3000 Mpa compressive strength ensures the tube withstands mechanical loads in high-temperature environments, thereby reducing deformation risk during operational stress. This structural integrity is essential in maintaining protective performance where pressure fluctuations occur.

Q2: What handling and storage conditions are recommended?
A2: Store the tube in a low-humidity, temperature-controlled environment to preserve its mechanical and thermal properties. Use the provided anti-static, cushioned packaging to minimise contamination and mechanical shock during transport and storage.

Q3: What is the significance of the tube’s 29 W/(m·k) thermal conductivity?
A3: The thermal conductivity of 29 W/(m·k) facilitates efficient heat dispersion within high-temperature systems, thereby reducing local thermal gradients. This controlled heat transfer is key to preventing thermal-induced material stress and maintaining consistent performance.
