Pipes (tubes)


Tubes and tube sections are hollow products, coiled or not coiled in coils, having a constant cross-section with only one closed cavity throughout the entire length of the product in the shape of circles, ovals, rectangles (including squares), equilateral triangles, or regular convex polygons, and having a uniform wall thickness. Products with a rectangular (including square), equilateral triangular, or regular convex polygonal cross-section with rounded corners along their entire length should also be classified as tubes and tube sections provided that their internal and external cross-sections are concentric and have the same shape and orientation. Tubes and tube sections having the aforementioned cross-sections may be polished, coated, bent, threaded, drilled, tapered, expanded, coned, or fitted with flanges, gaskets, or rings at their ends.
