Le tuyau de soudage à l'arc submergé longitudinalement est subdivisé en tuyau d'acier UOE, RBE, JCOE selon ses différentes méthodes de formage. Les tubes en acier soudés à haute fréquence longitudinaux ont les caractéristiques d'un processus relativement simple et d'une production continue rapide, et sont largement utilisés dans la construction civile, la pétrochimie, l'industrie légère et d'autres secteurs. Principalement utilisé pour transporter des fluides basse pression ou transformé en divers composants d'ingénierie et produits industriels légers.
