Which characteristic is most critical when selecting tubing for pressurized applications?

In pressurized applications, selecting the appropriate tubing involves considering multiple factors, each playing a vital role in ensuring safety and functionality. The characteristic that is most critical includes flexibility, wall thickness, and material type.

Flexibility is important because it determines how well the tubing can accommodate movement within the system without kinking or breaking. This is particularly essential in environments where vibration or thermal expansion might be present.

Wall thickness is crucial as it affects the tubing's ability to withstand internal pressures. Thicker walls can endure more pressure, reducing the risk of rupture or leaks. This characteristic is particularly significant for applications with high pressure or where the risk of puncture is heightened.

Material type impacts the tubing's compatibility with the fluids it will carry, resistance to corrosion, temperature thresholds, and overall structural integrity. Different materials have varying strengths and weaknesses, making the correct choice critical to ensuring longevity and safety under pressure.

Given that all these factors contribute significantly to the performance and safety of tubing in pressurized applications, it’s clear why each plays a critical role, making the selection of all three characteristics essential.
