The pressure that a steel tube can hold depends on various factors such as its dimensions, thickness, material grade, and the specific application it is intended for. Without knowing the exact specifications of the steel tube in question, it is challenging to provide a specific value.
To determine the maximum pressure a steel tube can withstand, engineers usually perform calculations based on the tube's dimensions and material properties. Additionally, industry standards and codes are often followed to ensure safe usage and performance.
If you have a particular steel tube in mind with specific dimensions and material grade, I might be able to assist further in calculating or estimating its maximum pressure capacity. However, for precise and safe results, it's essential to consult with a qualified engineer or refer to relevant technical documentation and standards.
