The performance of prestressed metal corrugated pipes under extreme conditions is specifically as follows:
Under High Temperatures: The working temperature range of prestressed metal corrugated pipes is from -80℃ to 140℃. Materials for corrugated pipes operating at high temperatures should possess sufficient thermal stability. As the working temperature increases, the material's elastic modulus decreases, which leads to a reduction in the stiffness, pressure resistance, and fatigue life of the corrugated pipe.
At Low Temperatures: For corrugated pipes used in low-temperature environments, they should possess excellent low-temperature performance. In low temperatures, the material's brittleness is more sensitive to surface defects, so strict control over the material's surface quality is essential.
In summary, the performance of prestressed metal corrugated pipes under extreme conditions may be affected to some extent.
