GNEE P265GH LSAW Pipe Production Process

Longitudinal welded steel pipes are produced by feeding a certain specification of strip steel coil into a round pipe shape through a high-frequency welding machine unit, where the longitudinal seam is welded to form the steel pipe. The shape of the pipe can be round, square, or irregular, depending on the diameter rolling after welding. The specific process involves opening and straightening the end of the steel coil and feeding it into subsequent equipment. After uncoiling, the strip steel is leveled, the ends are trimmed, and the strip is sheared with a circular disc cutter before recoiling. The raw material from the steel mill is of a specific width, which is cut to the corresponding width based on the actual length of the pipe. During welding, I-shaped bevels are typically used to ensure uniform heating along the thickness direction and facilitate bevel preparation. After uncoiling, the strip steel is further leveled, the ends are trimmed, and scarfing (butt welding) is performed to ensure the continuous production of the forming unit. The prepared strip steel enters the continuous forming unit, where it is gradually bent into a round pipe by the action of squeeze rollers. The edges of the strip steel are heated by a high-frequency welding machine to welding temperature, then pressure welded by squeeze rollers. Subsequently, scarfing removal devices are used to remove internal and external burrs formed by the melting or plastic state of the metal squeezed onto the inner and outer surfaces of the pipe. After a period of air cooling, the pipe is water-cooled to prevent bending deformation due to air cooling. The steel pipe produced by the squeeze rollers has a certain ellipticity in its cross-section, with the outer diameter slightly larger than the finished pipe. To obtain precise outer diameter and cross-sectional shape of the steel pipe, cold sizing is performed on the welded pipe by a sizing machine after water cooling. The sized welded pipe is then cut into specified or multiple length sections while in motion, meeting the corresponding tolerance requirements.
