This paper tests whether Antidumping (AD) protection affects the market power of importcompeting domestic firms. We use panel data of about 4000 EU producers that were involved in AD cases to estimate markups before and after the filing of a case. Our findings indicate that AD protection has positive and significant effects on domestic markups, except in cases where import diversion after prote...

Abstract In this study, the mechanical damage of Basalt/E-glass hybrid fiber-reinforced polymer composite tubes was evaluated experimentally using Micro hardness on transverse direction, uni-directional static tensile loading, and Quasi-static compressive loading. The Burn-off test method has been studied for volumetric fraction tubes. multi-layer composed eight layers plies at constant fiber t...

The aim of this study is to investigate the boiler tube failure mechanism using finite element analysis and experimental Analysis. numerical software used ANSYS steady-state thermal static structural analysis. independent variable for temperature from flue gas wall thickness tube. scope determine distribution, von mises stress, deformation safety factor by implemented design experiment. materia...

Wall-thickness eccentricity is a major dimensional deviation problem in seamless steel tube production. Although eccentricity is mainly caused by abnormal process conditions in the cross-roll piercing mill, most seamless tube plants lack the monitoring at the hot piercing stage but only inspect the quality of finished tubes using ultrasonic testing (UT) at the end of all manufacturing processes...

Two high-strength low-alloyed steels alloyed with various Nb contents were prepared using continuous casting (CC) technology. In the round Steel 30Nb CC billet, it was segregation of C and in central equiaxed zone that promoted precipitation primary NbC carbides at grain boundaries. After processing into seamless tubes, micron-sized located middle bands, surrounded by many nano-sized formed dur...
