过去,在国内石油企业中,耐氢诱导裂纹(以下称耐HIC钢)钢只限于用在含有硫化氢潮湿环境下的40公斤级钢制压力容器(板厚30mm以下)和换热器上。石油危机后,含硫气体的收集装置和海上注水注气采掘装置的建设,尤其是焦油砂和油页岩的加压采掘装置都正在进入实用化阶段。这些装置中的分离器都处在高压而且是严格的含硫条件下使用。这些用途促使着极厚钢板和耐硫管线用钢的生产技术发展,根据这些要求,成功地开发了耐氧诱导裂
In the past, the resistance to hydrogen-induced cracking (hereinafter referred to as HIC-resistant steel) in the domestic oil industry was restricted to 40 kg steel pressure vessels (plate thickness 30 mm or less) and heat exchangers in humid environments containing hydrogen sulfide. After the oil crisis, the construction of sulfur-containing gas collection facilities and offshore water injection and gas extraction and extraction facilities, especially the pressurized extraction of tar sands and oil shales, are entering the practical phase. Separators in these units are used under high pressure and under severe sulfur-containing conditions. These uses have led to the development of technologies for the production of very thick steel and sulfur-tolerant pipeline steel. Based on these requirements, the successful development of oxygen-induced cracking
