In-bulk steel degradation and a decrease in characteristics of brittle fracture resistance of pipeline steels under long-time operation increase significantly a failure risk. Therefore, deterioration of pipelines under operation calls for effective methods for currenWater-Brash 发表于 2025-3-27 17:23:34
https://doi.org/10.1007/978-3-322-81418-0of steel degradation is damaging along the boundaries between pearlite and ferrite grains manifested by more intensive etching the boundaries with extraction of cementite particles from the matrix. The most obvious effect of degradation is revealed for the steel 17H1S, and the least one for the stee脾气暴躁的人 发表于 2025-3-27 20:23:26

The need to transport fluids over considerable distances calls for carbon steel as construction material as it guarantees the required tensile strength and toughness properties.
