本文首先论述抗硫化物应力腐蚀开裂防喷器组设计制造的重要性,然后指出影响SCC发生的因素,这些主要因素是应力、环境以及材料对SCC的敏感性,其中包括显微结构、屈服强度、硬度和冷变形。作者根据这些因素和相关标准,提出防喷器抗SCC在设计和制造时应遵循的几项原则和工艺措施。 This paper first discusses the importance of the design and manufacture of the SSP group, and then points out the factors that affect the occurrence of SCC. The main factors are the stress, the environment and the sensitivity of the material to the SCC, including microstructure, yield strength , Hardness and cold deformation. Based on these factors and related standards, the author puts forward several principles and technical measures to be followed when designing and manufacturing BOP SCC.
