How is a continuous cylindrical section without longitudinal or circumferential joints described ____________________?
Show answer Hide answer
Answer: E. seamless section
Explanation
A continuous cylindrical pipe produced without any longitudinal or circumferential welded joints is known as a seamless section. Manufacturing this geometry without seams ensures uniform structural integrity throughout the entire length of the component. Eliminating weld lines removes potential weak points where high-pressure failures or corrosive cracking could otherwise originate. Seamless metal tubes are typically manufactured through hot piercing or extrusion of solid cylindrical metal billets. Welded pipes require forming flat metal plates into cylinders and fusing the touching edges using electric resistance or arc welding. The absence of a weld seam provides superior mechanical properties and higher burst pressure ratings for demanding industrial applications.
A jointless section is a colloquial descriptor rather than the standard engineering terminology used for manufactured tubular components. Homogeneous materials possess uniform properties throughout their volume, but this term does not specifically describe cylindrical geometry. The term manufactured section is overly broad because it applies to virtually any fabricated engineering component regardless of shape.
