The small punch test (SPT), as a testing method for acquiring the mechanical properties of materials in narrow areas, possesses unique advantages and great potential in characterizing the mechanical properties of pipeline girth weld joints. Taking the materials in various regions of X80 pipeline girth weld joints as the research objects, this paper combines in-situ tensile tests, SPT, finite element (FE) simulation, and machine learning (ML) methods to achieve the goal of efficiently determining the constitutive relationship of materials in various regions of pipeline girth weld joints. Specifically, the true stress-strain curves and SPT load-displacement curves of materials in various regions of X80 pipeline girth weld joints are obtained through in-situ tensile tests and SPT. And the reliability of the SPT FE model is verified with the help of experimental data. Many numerical simulation works are carried out to establish a ML database. Finally, a deep learning model (DLM) with a complex structure is established, which can realize the function of determining the true stress-strain relationships of materials from the SPT load-displacement data. This DLM performs well on both FE simulation data and experimental data, with a prediction error lower than 4.3 %. Moreover, it has a relatively fast prediction speed, enabling it to efficiently predict the constitutive relationships of pipeline steel materials and providing the possibility for practical applications in on-site engineering.</div></div>","PeriodicalId":54946,"journal":{"name":"International Journal of Pressure Vessels and Piping","volume":"217 ","pages":"Article 105570"},"PeriodicalIF":3.0,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144190445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To detect leakage losses, an experimental study is conducted to collect a dataset of 969 pressure signals, including leakage, stability, and interference signals. The results show that as the volume flow decreases and the distance between the leakage point and the sensor increases, the signal strength significantly attenuates. This attenuation reduces the distinguishability of leakage signals—especially under noisy conditions, where noise may even obscure the leakage features—thereby increasing the difficulty of accurate localization. To mitigate noise in signals, this paper proposes an adaptive denoising algorithm (IGWO-VMD) based on variational mode decomposition (VMD) and an improved grey wolf optimizer (IGWO), which effectively suppresses noise and enhances leakage features. In addition, to achieve accurate leakage localization in the presence of interference signals—such as valve closures that closely resemble leakage signals—a hybrid neural network combining temporal convolutional networks (TCN) and bidirectional long short-term memory (BiLSTM) is proposed. This model exhibits strong feature extraction capabilities and robust performance in complex signal environments, effectively reducing the risk of misjudgment. Comparative evaluations with state-of-the-art methods across multiple performance metrics show that the model accurately identifies leakage signals and precisely localizes leakage positions, demonstrating its potential as a reliable solution for intelligent water pipeline management.</div></div>","PeriodicalId":54946,"journal":{"name":"International Journal of Pressure Vessels and Piping","volume":"218 ","pages":"Article 105564"},"PeriodicalIF":3.0,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144230710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Determining the expansion limit of the SET is of great significance for reducing costs, improving design efficiency and ensuring construction safety. Therefore, a new method for studying and predicting the expansion limit of the SET is proposed. Based on the Johnson-Cook constitutive model and failure model, combined with the expansion test of the SET and the material tensile test, a numerical simulation of the expansion failure behavior of the SET were conducted. The influence of sensitive parameters such as expansion speed, pipe material, ovality, wall thickness, and wall thickness unevenness on the limit expansion rate of SET were systematically analyzed. The research results show that: 1) Either too fast or too slow an expansion speed will reduce the expansion limit of SET. The recommended expansion speed for 20G is 1 m/s 2) The limit expansion ratios of 20G, 316L, and Al (2024) pipe materials are 27 %, 51 %, and 22.5 % respectively. 3) For every 1 % increase in the ovality of the pipe, the limit expansion rate of the SET decreases by approximately 0.26 %. For every 1 mm increase in the wall thickness of the pipe, the limit expansion rate of the SET increases by approximately 0.65 %.

While the physical properties of the capsule itself lead to the phenomenon of insufficient and non-uniform localized heat and pressure transfer, thinning of the capsule becomes an important solution. Inevitably, capsule wall thinning will bring the risk of failure, especially at welded joints, so the quality control of the capsule is crucial. In order to achieve joint quality enhancement, this paper investigates the laser arc composite welding head used in the HIP process, which uses stainless steel wires in the welding of mild steel plates. The results show that the heat-affected zone of welded joints is characterized by the susceptibility to high-temperature plastic loss, which will become a potential risk during capsule operation. Furthermore, it has been demonstrated that thinner plates are more susceptible to the effects of welding action. The resultant welding stresses have the potential to compromise the capsule's capacity to regulate shape, and may precipitate high-temperature plastic loss. In light of these findings, this paper proposes a solution that involves replacing the heterogeneous weld with a homogeneous weld. This modification is expected to universally weaken the welding stress from the welding principle. Furthermore, the introduction of an equal-strength matching method between the weld and the base material is anticipated to result in the involvement of the weld region in the deformation process when high-temperature plastic loss occurs in the heat-affected zone. This, in turn, is expected to inhibit the occurrence of brittle fracture and thereby strengthen the welded joint.</div></div>","PeriodicalId":54946,"journal":{"name":"International Journal of Pressure Vessels and Piping","volume":"217 ","pages":"Article 105562"},"PeriodicalIF":3.0,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144137805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
