“…Therefore, O 2 content was divided into three ranges [0, 1], (1, 2) and [2,3] according to the recommended materials. The higher the O 2 content was, the more serious the In addition, the recommended materials with O 2 content in the range (1, 2) and [2,3] were determined by the same working condition division method, as shown in Table 15. Corrosion material selection in Table 15 is only applicable to material selection in the in-situ condition range in Table 7.…”

“…1 The safety of pipelines is often closely related to their inherent properties and environment. 2,3 At present, the excellent quality and cost-effectiveness of carbon steel have made it often used in various process treatment systems in oil and gas fields. However, in harsh corrosive environments, certain types of carbon steel are highly inapplicable and can undergo rapid corrosion perforation failure in the short term.…”

The corrosion in the aqueous environment of CO2–H2S–O2–SO2 is extremely severe, causing frequent failures of pipeline and posing a challenging issue for material selection. This paper drew on excellent standards and past experiences to provide a suitable method for selecting materials. The method consisted of four components: standard primary selection, corrosion evaluation selection, mechanical property selection, and economic final selection. A case study demonstrated that the applicable materials for the environment (total pressure of 1.5 MPa, temperature of 30–120 °C, H2S content of 0.1–1.5%, CO2 content of 8–55%, SO2 content of 0–0.00015% and O2 content of 1–3%) were composed of 2Cr13 or 316L. Additionally, the main control factors for corrosion rate were ranked as follows: O2 > H2S > temperature > CO2 > SO2. And a reduction in mechanical properties was observed for 2Cr13, 316L, and 825 after corrosion.

The residual stress magnetic measurement method is a new non-destructive testing method developed in recent years. This article studies the magnetic properties of ferromagnetic materials and the principle of stress relationship, develops a nine pole residual stress magnetic measurement instrument, and conducts practical engineering testing of residual stress in high-risk and crack prone areas of lifting equipment. A safety evaluation method for lifting equipment that considers both residual stress and working stress is proposed. The engineering application of residual stress detection in lifting equipment shows that the magnetic anisotropy detection method for residual stress is more direct, reasonable, fast, and convenient. The safety evaluation of lifting equipment needs to consider the impact of residual stress, and the safety evaluation of lifting equipment considering the impact of residual stress is more safe and scientific.

“…A quantitative variation law of the magnetic signal with internal pressure and detection height also was obtained. He et al [25] developed a magnetic stress-detection method for girth welds with unequal wall thickness. A new index, residual strength ratio (RSR), was proposed to quantify the stress damage level of girth welds.…”

During the construction and long-term operation, stress concentration zones (SCZs) will inevitably occur in buried pipelines. It may cause pipe leakage or fracture failure. Therefore, it is essential to inspect the precise position and stress damage degree of SCZs. Pipeline non-contact magnetic-based stress inspection (PMSI) is an important issue in the oil and gas pipeline stress inspection field. In order to determine the response of the non-contact magnetic gradient signal on stress damage of SCZs, we established a pipeline magnetic-based stress detection model to analyse the three-dimensional magnetic signal of SCZs. The effect of changes to the axial stress value, the stress concentration length, the detection height, and the gradiometer jitter is also studied. Moreover, the PMSI is carried out on a 10.3 km LNG buried pipeline, which is validated by the excavation inspection results. The results indicate that the Gx shows sinusoidal fluctuation near the SCZ. The Gy and Gz reach a peak value. The Gmax increases with the severity and length of SCZs. Two level-II SCZs and two level-III SCZs are found.
