Title (EN) ENHANCED WELDED PIPE, THREADED CONNECTIONS, AND METHODS FOR ACHIEVING THE SAME
(FR) TUYAU SOUDÉ RENFORCÉ, CONNEXIONS FILETÉES ET LEURS PROCÉDÉS DE RÉALISATION
Abstract:
(EN) A tubular member (100) includes a tube body (109), a tube end (112,113), an exterior surface (140), an interior surface (142), a nominal wall thickness, a longitudinal axis (111), a welded seam (110), and a patch of material (205). The welded seam forms an arcuate portion of the interior surface, and the patch covers a portion of the interior surface that includes a portion of the welded seam, extending from the tube end to an axially spaced first location. The resulting interior surface from the tube end to the axially spaced first location has a uniform inside diameter.
(FR) L’invention concerne un élément tubulaire (100) comprenant un corps de tube (109), une extrémité de tube (112, 113), une surface extérieure (140), une surface intérieure (142), une épaisseur de paroi nominale, un axe longitudinal (111), une soudure (110) et une pièce de matériau (205). La soudure forme une partie arquée de la surface intérieure, et la pièce recouvre une partie de la surface intérieure qui comprend une partie du cordon soudé, s'étendant de l'extrémité du tube à un premier emplacement espacé axialement. La surface intérieure résultante de l'extrémité de tube au premier emplacement espacé axialement a un diamètre intérieur uniforme.
