This paper compares the design rules in main standards including GB/T 150.3, GB/T 4732.3, ASME Ⅷ-1, ASME Ⅷ-2, ASME Code Case 2286-6 and EN 13445-3. The theoretical basis of design rules among these standards is presented while equations for calculating key parameters are compared. Torispherical and ellipsoidal heads are designed as hemispherical heads by equivalent methods. The buckling pressure difference between torispherical and ellipsoidal heads and corresponding equivalent hemispherical heads is compared by finite element eigenvalue buckling analysis. For most torispherical heads, the equivalent design method is conservative. For ellipsoidal heads, the equivalent design method adopted in EN 13445-3 is conservative. The Four-Center equivalent method is aggressive for thin heads but conservative for thick heads. Further, head thicknesses calculated according to different standards for six design cases are compared. The results indicate that EN 13445-3 is more economical for low design pressure, and GB/T 4732.3, ASME Ⅷ-2 and ASME Code Case 2286-6 are more economical for high design pressure. For moderate design pressure, the choice of the standard depends on the material, with GB/T 4732 being more economical for Q345R, GB/T 4732.3, ASME Ⅷ-2 and ASME Code Case 2286-6 for S30408 and ASME Ⅷ-2 for S22053. Meanwhile, the thicknesses calculated by ASME Ⅷ-1 are always the largest.

The aim of the overlaying process was to enhance the corrosion resistance and erosion performance of the base alloy. Pulsed current gas tungsten arc welding was employed as the overlaying technique. Detailed microstructural assessments were performed using optical microscopy and field emission scanning electron microscopy, supplemented by energy dispersive X-ray spectroscopy. The ratio of ferrite to austenite was evaluated through X-ray diffraction analysis and measurements using a ferrite scope. Results indicated that increasing the heat input reduced the ferrite phase in the ER 2594 and ER 2209 overlays. To assess corrosion behavior, Tafel polarization and electrochemical impedance spectroscopy tests were carried out on both the substrate and the overlay materials. Among the overlays, ER 2594 produced under moderate heat input showed the best corrosion resistance, with a notably low corrosion current (i<sub>corr</sub> = 6.6 nA/cm<sup>2</sup>) and higher impedance (Z) compared to other overlays. Furthermore, erosion performance was evaluated using a slurry test with water containing 5 wt% sand particles at a flow rate of 10 m/s, with an impact angle of 30°, and varying duration.

Firstly, a method for the quantification and localization of small defects in pipes was developed using the relationship between reflection coefficients, section loss rates and signal amplitudes.

Due to the increasing trend of using functionally graded cylinders in industries, this paper endeavours to explore the applicability of thermal autofrettage to functionally graded cylinders for the first time. A theoretical approach is made to investigate the development of stresses during thermal autofrettage of a thick-walled cylinder made with functionally graded material. Under the application of a through thickness temperature gradient to the functionally graded cylinder, the loading stage of thermal autofrettage is modelled to exhibit elastic-perfectly plastic behaviour incorporating von Mises yield criterion. The cylinder end condition is assumed to be open-ended conforming generalized plane strain condition. The in-loading thermo-elastic-plastic stress formulation is carried out and post-unloading of temperature gradient, the residual stresses induced in the cylinder are evaluated. The current process is exemplified for a typical FG cylinder composed of aluminium alloy (Al A359) and silicon carbide (SiC). The analysis reveals that a significant amount of compressive residual stresses of the order of 0.99 times the yield strength at the inner radius can be induced by thermal autofrettage in FG cylinder which enhances its pressure carrying capacity. For instance, in the present Al A359/SiC FG cylinder of wall thickness ratio 3, the maximum achievable pressure carrying capacity is nearly 40 %.</div></div>","PeriodicalId":54946,"journal":{"name":"International Journal of Pressure Vessels and Piping","volume":"216 ","pages":"Article 105505"},"PeriodicalIF":3.0,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143644317","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}
