The crack position and direction was determined, by using non-destructive tests. Distribution of outer surface temperature was measured by using thermography method and for the measurement of inner surface ten thermocouples were installed inside the casing wall. The temperature data was applied as ...
An original erosion-resistant coating (ERC) establishes a new category with a system that resists erosion inside pipes located near fracking wellheads, thereby reducing downtime maintenance costs and enhancing drilling productivity.Corrosion Control: Options for Combating Damage Due to Black Powder in Pi...
The specimens were tested in the presence of a corrosive environment at low loading frequencies (0.3 Hz). The medium used was an aqueous solution with 115.000 ppm of chloride, pH adjusted to 4, and CO2 bubbling inside the solution during the test. The end of the test was determined in ...

(Bakos, Fidanidis, & Tsagas, 1999). The system could maintain an inside temperature of 20 °C when the outside temperature was 7 °C and the inside temperature of 15 °C when the outside temperature falls to 2 °C.Kondili and Kaldellis (2006)studied the heating performance of a ...
In a turbine disk and a gas turbine, the turbine disk is firmly connected to a rotor () to be rotatably supported; a plurality of rotor blades () is arranged on an outer circumference thereof in a circumferential direction; first cooling holes () penetrating the turbine disk from inside to...
A gas turbine engine rotor disk has a single-piece hub with a radially-outer surface, and with an annular cavity inside the single-piece hub. The annular c... HO Eric,J Zeinalov 被引量: 0发表: 2020年 Crack growth rate and lifetime prediction for aviation gas turbine engine compressor ...
If it is necessary to contain the leak immediately on site, the cylinder may be placed inside a special larger cylinder “coffin” specially designed for this type of situation. This coffin may then be moved to a location where it can be connected to a scrubber and safely vented. This type...
Particularly, when the stress dropped suddenly, the EP signal has a sudden mutation, and the acoustic emission (AE) signal suffered the pulsed increase, while the crack grew and expanded rapidly. Furthermore, when local severe damage occurs inside the coal mass, there was abnormal EP spatial ...
soap inside a spray bottle and spray the solution directly on pipes, hoses, and valves. If there is a leak, the solution will bubble where the leak is detected. Be sure to avoid using any soaps that contain ammonia, as this can cause brass fittings to become brittle and crack. ...
