UOE is a kind of steel tube molding mode: molding the flat-panelto a U shape with a press first, then to an O shape, welding it,and expanding the diameter mechanically at last. It is featured byprotection of materials, high molding rate, and effective guaranteeof higher mechanical property of steel tubes made of samematerials. UOE longitudinal seam double-sided submerged arc weldedsteel tubes, with high strength, high toughness, high tensilestrength, high corrosion resistance and acid resistance, can beused for undersea petroleum and gas pipelines, land petroleum andgas pipelines in severe cold areas and places with big fall, andcoal slurry and ore slurry pipelines. This kind of steel tubes iswidely used in important oil and gas pipelines in the globe.
