What Are The Advantages Of Straight Seam Welded Pipes?

1. 100% ultrasonic testing of the base material ensures the inherent quality of the pipe body.
2. There is no unwinding and disc shearing process, so the material will have fewer pits and scratches.
3. Welding is performed in a straight line in a horizontal position after the molding is completed. Therefore, the staggered edges, seams, and pipe diameter and circumference are well controlled, and the welding quality is excellent.
4. There is basically no residual stress in the finished pipe after stress relief.
5. The welding seam is short and the probability of defects is small.
6. Can conditionally transport moist sour natural gas.
7. After diameter expansion, the geometric size accuracy of the steel pipe is high, which greatly facilitates on-site butt welding of the pipeline and improves the quality of the entire pipeline.
