 Longitudinally Submerged Arc Welded Steel pipe



How can there be longitudinal weld when steel pipe is matched?



The welding current of the positioning weld shall be selected to be larger than that of the formal welding, usually 0% to 5%, to ensure the penetration of welding.5 welding of pipelines: the quality of welding seams shall be in accordance with the relevant provisions of GB50 ii-6-9 paint ii. The welding seams shall be smooth, uniform in width and width, and the root shall be thoroughly welded without obvious concave and convex defects and undercut phenomenon. The strengthening surface of welding seams shall be about two millimeters higher than the pipe surface, and the edge of groove shall be two to three millimeters.When the land pipe is welded to the flange, the pipe shall be inserted into two thirds of the flange, the flange and the pipe shall be vertical, and the axes of the two shall coincide.


A. the slope of horizontal pipeline shall not be less than 0.3%.


B. Before welding, the welding environment shall be checked, and the drying and cleaning of welding installation equipment and welding materials shall comply with the specifications and welding operation regulations.


C. When welding double-sided welds, the back side of the root of the weld shall be cleaned and inspected. The back side of the weld shall not be welded until the defects are cleared.It is stipulated that the welding seam of root cleaning shall be inspected by appearance before welding.


D. Bevel shall be made before welding of pipes with a wall larger than 4 mm, and there shall be no interlayer, crack, machining damage, burr, flame cutting slag and other defects on the surface of the groove.After welding, the coating should be clean, and the welding joint should be even fish scales, and there should be no porosity, slag inclusion, cracks, welding nodules and other phenomena, and the length of the meat should be within the requirements of the specification
