The aim of the research is examining the influence of flowing fluid on the susceptibility of materials to environmental stress cracking such as stress corrosion cracking (SCC) and sulfide stress cracking (SSC) using the fracture mechanics circumferential notched tensile (CNT) specimen. A novel SCC/SSC testing flow loop was invented for performing the experimental work. The testing flow loop has been registered as a patent in recognition of its novelty and practical applications in several industries. The experimental conditions were testing the susceptibility of heat treated P110 steel to SSC in deoxygenated stagnant and flowing liquid consisting of 0.01 M Na₂S₂O₃ (as a supplier for H₂S) and 3.5 w% NaCl at room temperature. The results indicate that the heat treated P110 steel was susceptible to SSC in stagnant solution, while it was not susceptible in flowing fluid.

该研究的目的是使用断裂力学圆周缺口拉伸（CNT）样品研究流动流体对材料对环境应力开裂的敏感性的影响，例如应力腐蚀开裂（SCC）和硫化物应力开裂（SSC）。发明了新颖的SCC / SSC测试流程回路来执行实验工作。测试流程回路已被注册为专利，以表彰其新颖性和在多个行业中的实际应用。实验条件是测试热处理的P110钢在脱氧的停滞和流动的液体中对SSC的敏感性，该液体由0.01 M Na ₂ S ₂ O ₃（作为H ₂的供应商）组成S）和室温下的3.5 w％NaCl。结果表明，热处理过的P110钢在滞留溶液中易受SSC的影响，而在流动流体中则不易受SSC的影响。
