How to deal with the thermal expansion and shrinkage of seamless steel tube

    First, how to prevent thermal expansion and contraction

    If this process is extremely slow and the temperature difference is not large, after cooling, it can basically be restored to its original shape, for example, placing an open-air steel plate on the noon evening; if this process is more rapid, it will be remnant due to the expansion of the steel that is forced by the warming. Deformation, after the temperature is restored, the deformation will not be restored, the warping is inevitable, such as the welding process, and if the gas welding is used to correct the deformation technology.

    Second, how to prevent thermal expansion and contraction in buildings

    Seamless steel tube play a huge role in construction and engineering. Seamless steel tube are subject to thermal variability, especially when they are used to transport natural gas, water, and petroleum on pipelines. Due to the fact that the liquid is often hot and deformed, thermal expansion occurs. Cold shrinkage is the property of the vast majority of materials, especially the steel temperature is more sensitive to temperature expansion. The steel plate is thin and wide, and it is uneven when subjected to high temperatures.
