The quest to replace toxic chemicals in the nearest future is revolutionizing corrosion inhibitor research world by turning its attention plant biomaterials. Herein, we report inhibiting potential of butanolic extract date palm leaves (BUT) on API 5L X60 carbon steel 15 wt.% HCl solution. mass loss, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), linear (LPR), ...

This study conducts a capacity factor calibration for steel and steel-concrete composite columns with helical seam pipe (also known as spiral welded tube) sections considering the following three member types: (i) under axial compression, (ii) concrete-filled tubes (CFSTs) (iii) CFSTs combined compression uniaxial bending due to load eccentricity. The has been conducted both forward inverse rel...

The process of thermo-mechanically controlled rolling in the conditions Steckel mill Ferriera Valsider plant was developed for first time hot-rolled coils sizes 12 mm × 1510 from steel X65 grade further production electric welded pipes according to API-5L standard. provides carrying out roughing-rolling two stages facilitating forming a smaller austenite grain and therefore more dispersed homog...

The hydrogen embrittlement (HE) leads to severe steel degradation of mechanical properties. atoms diffuse into the and get positioned reversible irreversible trap sites. pipe transport oil gas needs be welded construct long-distance pipeline projects; thus, friction-stir welding (FSW) has proven an excellent alternative joining these pipelines. Therefore, this work assessed analyzed influence o...
