Q345 straight seam submerged arc welded steel pipe is a steel pipe with excellent welding performance and is widely used in various engineering fields.
Submerged arc welding is a method in which the arc burns under the flux layer for welding. Its advantages are stable welding quality, high welding productivity, no arc light and little smoke. Therefore, Q345 longitudinal submerged arc welded steel pipe can ensure high welding quality and production efficiency during the manufacturing process, while having lower pollution emissions and complying with environmental protection requirements.
Q345 straight seam submerged arc welded steel pipe also has good mechanical properties and corrosion resistance, and can meet the needs of use in various complex environments, such as transporting fluids, withstanding pressure, resisting corrosion, etc. Therefore, Q345 longitudinal submerged arc welded steel pipe is widely used in pipeline systems in petroleum, natural gas, chemical industry, electric power, urban public utilities and other industries.
