The use of titanium alloys for details of downhole hammers [PDF]
, 2016 The influence of cementation technology of titanium alloy Ti-Al-Mn on its wear resistance is studied. It is established that after lubrication a friction pair with mineral oil the wear resistance of the cemented titanium alloy is comparable to wear ...

WATER HAMMER IN PIPELINE WITH DIFFERENT CHARACTERISTICS OF VALVE CLOSING AND UNSTEADY WALL FRICTION [PDF]
Civil Engineering Journal, 2019 This paper presents an analytical investigation of water hammer pressure variation in a reservoir-pipe-valve system. Laplace transform method is used to get the analytical solutions for different characteristics of the valve closing. Specifically, sudden

Analysis of natural gas flow reversal in integrated energy system based on dynamic simulation
Energy Reports, 2021 The inertial water hammer pressure propagates along the pipeline at the speed of sound wave, which makes the pressure along the pipeline rise or fall rapidly and the inertial water hammer pressure attenuate in the process of propagation.

Modeling and analysis of water-hammer in coaxial pipes
, 2014 The fluid-structure interaction is studied for a system composed of two coaxial pipes in an annular geometry, for both homogeneous isotropic metal pipes and fiber-reinforced (anisotropic) pipes.

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated
