Tubos Estruturais Circulares

Tabela das 142 bitolas de tubo estrutural de seção circular, laminados a quente pela Vallourec Tubos do Brasil (Usina Barreiro), diâmetro de 33,4 mm a 355,6 mm. Fabricação conforme ABNT NBR 8261, que também define graus de aço, tolerâncias dimensionais e regra de designação.

Por simetria da seção circular, Ix = Iy, Wx = Wy, Zx = Zy e rx = ry — publicados numa coluna só por eixo, como nas cantoneiras.

Fontes: Catálogo "Tubos Estruturais, Seção Circular, Quadrada e Retangular" — Vallourec & Sumitomo Tubos do Brasil, Usina Barreiro · ABNT NBR 8261:2019 — Tubos de aço-carbono, com e sem solda, de seção circular, quadrada ou retangular para usos estruturais

Método: Extração via pdfplumber (find_tables + extract_tables) da seção "Seção Tubular Circular (TC)" (4 páginas). O diâmetro e a coluna U são células mescladas, centradas no grupo de espessuras, e por isso não alinham com nenhuma linha da grade extraída — foram recuperados casando a posição vertical de cada rótulo (via extract_words) com o centro de cada linha de dado. Conferido por amostragem visual (menor e maior bitola) contra o render das páginas do catálogo original.
