The inhibition properties of synthesized imine compounds N,Nʹ-bis(2,4-dihydroxyhydroxybenzaldehyde)-1,3-Propandiimine, N, N′-bis(2,4-dihydroxypropiophenone)-2,2-dimethylpropandiimine, N,Nʹ-bis(2,4-dihydroxyacetophenone)-1,3-Propandiimine has been investigated for API-5L-X65 steel corrosion in hydrochloric acid by scanning electron microscopy, potentiodynamic polarization and impedance spectrosc...

The corrosion behaviors of different weld heat-affected zones (HAZs) were investigated, comprising an API 5L X65 steel immersed in seawater with abundant native microbial community. Before tests, HAZ physical simulations performed at the peak temperatures 700 °C, 860 1000 and 1350 °C. Throughout 14 days immersion, various planktonic bacterial groups associated microbiologically influenced metab...

an experiment featuring waterhammer in viscoelastic pipes is presented in which the effects of pipe-wall viscoelasticity on waterhammer pressures are investigated. a large-scale pipeline apparatus made of polyvinyl chloride (pvc) at deltares, delft, the netherlands, has been used to carry out waterhammer experiments. tests have been conducted in a reservoir-pipeline-valve system consisting of a...
