Abstract

"TUBO CILìNDRICO PARA INSTALAçõES QUìMICAS INDUSTRIAIS". A invenção provê um tubo para ser utilizado em fornos onde passam meios gasosos e líquidos pelo tubo a partir de uma extremidade para a outra enquanto que submetidos a um aquecimento substancial e decomposição resultante do mesmo. O tubo cilíndrico é feito em uma liga de aço inoxidável a base de ferro-níquel-cromo que compreende em % em peso: no máximo 0,08% de C, 23-27% de Cr, 33-37% de Ni, 1,3-1,8% de Mn, 1,2-2% de Si, 0,08-0,25% de N, 0,01-0,15% de terras raras, e Fe e impurezas usuais. O tubo cilíndrico apresenta uma superfície externa lisa e uma superfície interna provida com vales e recessos que se estendem longitudinalmente com um perfil de fundo ligeiramente curvo."CYLINDRIC PIPE FOR INDUSTRIAL CHEMICAL INSTALLATIONS". The invention provides a tube for use in ovens where gaseous and liquid media pass through the tube from one end to the other while subjected to substantial heating and resulting decomposition. The cylindrical tube is made of an iron-nickel-chromium-based stainless steel alloy comprising by weight%: maximum 0.08% C, 23-27% Cr, 33-37% Ni, 1 , 3-1.8% Mn, 1.2-2% Si, 0.08-0.25% N, 0.01-0.15% rare earth, and Fe and usual impurities. The cylindrical tube has a smooth outer surface and an inner surface provided with longitudinally extending valleys and recesses with a slightly curved bottom profile.
