Ordinary steel pipes, such as tap pipes, are usually welded through plates after bending. You can find the weld on it. The diameter of steel is usually spiral.


Seamless steel pipes are usually formed by pressing the molten steel through the annular notch and then drawing, so that there is no welding. It is usually used in the performance of high-pressure equipment, especially in the bearing capacity, much higher than ordinary steel pipe.



For example, pipeline connection of hydraulic equipment. The welding position of common steel pipe is its weak link, and the quality of weld seam is also the main factor affecting its overall performance. People living in the North usually have experience with pipes or heating pipes in winter. The place where the explosion occurs is usually the weld. Welded pipe is not seamless steel pipe.
