Simulation Analysis of Sealing Characteristics of K-Shaped Metal Ring on Tubing Hanger
Shiyou jixie, 2021 To study the optimal precompression of the self-tightening metal sealing ring and its sealing performance affected by the pressure and temperature load of the working medium, a K-shaped metal seal ring on the tubing hanger is taken as an example.

STRENGTH ANALYSIS OF THE SPLIT RING OF THE TUBING HANGER LOCKDOWN MECHANISM
IZVESTIA VOLGOGRAD STATE TECHNICAL UNIVERSITY, 2020 The article discusses the analysis of the stress-strain state of the split ring of the locking mechanism of the pump and compressor pipe suspension in the unpressed position by analytical and numerical methods. In the analysis by numerical method, the rationale for using an elastic-plastic model of the material is given and the structural strength is ...

Risk Analysis of Tubing Hanger Installation Based on Fuzzy Bayesian Network
Shiyou jixie, 2020 To address the inability of quantified analysis due to the lack of actual data during the risk analysis process of tubing hanger installation, a fault probability calculation method based on fuzzy Bayesian network system is proposed.

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance
Advanced Functional Materials, EarlyView.A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Reliability Analysis of Subsea Christmas Tree System Based on FFTA and FMEA
Shiyou jixie, 2022 At present, most of the reliability analysis on subsea Christmas tree system only considers the influence of some typical fault modes on the system. Therefore, in the paper, the fuzzy fault tree analysis method(FFTA)and the fault mode and effect analysis

Hybrid Scaffolds Decouple Biochemical & Biophysical Regulation of Cell Phenotype
Advanced Healthcare Materials, EarlyView.Replicating tissue‐specific extracellular matrix is crucial for understanding its role in disease. This work demonstrates independent control over stiffness, composition and 3D collagen architecture using hybrid scaffolds: patterned collagen perfused with defined hydrogels.
