Pengaruh Pengisian Lilin Terhadap Kualitas Pembengkokan Pipa Galvanis Menggun…

ABSTRACT The bending process of galvanized pipes often causes cross-sectional deformation, one of which is ovality—a change in the pipe's cross-sectional shape from circular to oval. This deformation can affect the strength and reliability of piping systems. This study aims to analyze the effect of wax filling inside galvanized pipes prior to the bending process on the quality of the bending…
