| 摘 要： | 针对输送管道的3种主要开裂形式，即：高pH应力腐蚀开裂、近中性pH应力腐蚀开裂及氢致开裂，阐述其发生机理，比较其发生条件和形貌特征，并具体讨论环境溶液、阴极保护、涂层、温度、应力应变和材料等因素对开裂过程的影响。结果表明，环境、应力和材料对高pH应力腐蚀开裂、近中性pH应力腐蚀开裂及氢致开裂起到主导作用。

| Abstract: | With regard to three main cracking forms in oil & gas pipelines, i.e. high pH SCC, near-neutral pH SCC and hydrogen induced cracking (HIC), it is discussed well on the mechanism of their occurence, occurrence conditions, and characteristics. The controlling factors of SCC, and HIC, such as the environmental solution, catholic protection, coating, temperature, corrosion products, stress and strain, materials etc. are also discussed in detail. The results show that environments, stress and materials play important roles in high pH SCC, near-neutral pH SCC, and hydrogen induced cracking (HIC). |

| Keywords: | oil and gas gathering and transporting pipeline SCC (stress corrosion cracking) negative pole protection coating HIC (hydrogen induced cracking) |
