Pipelines made from welded tubes used for oil or gas transport under high pressure are often subjected to hydrogen damage because of the humid hydrogen sulphide contaminating these media. This process called the SSCC stress corrosion (sulfide stress corrosion cracking) is caused by the chemisorption dissociation of the humid H2S on surface of tubes. The atomic hydrogen created in this reaction is absorbed by the surface layer of the pipes and penetrates inside the steel. The migrating H atoms are trapped in gaps in the neighbourhood of the nonmetallic inclusions and other defects, where they are recombined to the H2 particle form. The inflow of the H atoms into these gaps and the exothermic recombination reaction of this element causes development of the H2 gas bubbles with the growing pressure, which summing up with the constant or pulsating pressure of the transported medium leads to nucleation and development of cracks, succoured by segregation of the atomic hydrogen in stress conce

在这里输入管道从焊接管用于石油或天然气运输高压下经常受到损害，因为氢的湿硫化氢污染这些媒体。这一过程称为SSCC应力腐蚀（硫化氢应力腐蚀开裂）的原因是化学吸附分解硫化氢的湿润表面管。氢原子在此反应是吸收表层穿透内管和钢。氢原子的迁移被困在缺口附近的非金属夹杂物和其他缺陷，他们在那里重组的氢粒子形式。

流入的H原子到这些差距和重组的放热反应的原因这一要素发展的氢气气泡的压力不断增加，其中总结与不变或脉动压力的运输中等导致核开发的裂缝， succoured的隔离的氢原子在应力集中在前面的顶点。因此，钢材用于这些设备应具有细粒度结构的连贯性或半连贯的MX阶段，加强和粒子的有限部分非金属夹杂物和杂质。
