In this paper, four quinoline quaternary ammonium salts were synthesized using quaternization reaction, which benzyl quinolion (BQL), naphthylmethyl quinolinium chloride (NQL), benzyl-8-hydroxy (BHQ) and 8-hydroxy (NHQ). The corrosion inhibition properties of the derivatives as inhibitors on P110 steel in 20% HCl solution at 60°C different concentrations investigated by weight loss electrochemical measurements. results showed that concentration inhibitor increases, rate decreased efficiency...
Under-deposit corrosion is widely present in the pipelines of oil and gas production, causing significant damage. In this paper, a novel electrochemical cathodic-polarization method was carried out to accelerate formation CaCO3 scale on X65 steel surface simulated solution containing scaling ions. Subsequently, pre-scaled placed high temperature pressure autoclave conduct weight-loss experiments situ measurements. The study mainly compared inhibition behavior four quaternary ammonium salt...
The impact of temperature on CO2 corrosion was investigated by weight loss, in situ electrochemical measurements, and characterization product film. results showed that with the increase temperature, rate decreased remarkably, which can be ascribed to different films formed metal surfaces. As increased, growth tendency FeCO3 crystals (012) plane becam more pronounced, ultimately forming a dense Synchrotron-based computed laminography analysis proved porosity products rising temperature....
Under-deposit corrosion is a key issue in various processes of oil and natural gas production. In this paper, the behavior X65 steel under CaCO3 scales was investigated, which are commonly occurred such environments. To simulate different conditions scaling, accelerated scaling achieved through cathodic polarization on samples. Subsequently, chemical immersion weight loss test performed over 72 h simulated produced water at 40°C with CO2 partial pressure 0.5 MPa (total 1 MPa). The results...
In this paper, a capable of loading, stress and strain monitoring system is developed, which based on fatigue reliability analysis theory. The 800 MN die-forging hydraulic press body structure pre-tightened condition was studied developed data processing methods. This also has on-line compressor structural static strength life prediction function, been conducted laboratory experiments. experiment using the actual use conditions close to at time piecewise continuous loading mode, signal any...
