Because there are sediments on the surface of the steel pipe, the sediments are prone to sintering under high-temperature annealing conditions, and these sediments may be released in gaseous or liquid states during the annealing process. During annealing, the amount of oxide generated will increase with the increase in temperature, and a small amount of MnO will be formed. Cr will be reduced to Cr2O3 under highly reducing conditions. If not cleaned in time, the residue of these sediments will not only affect the uniformity of the stainless steel pipe annealing, but also damage the surface of the stainless steel during use.
