Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a bending-resistant seamless pipe. Background Art

[0002] Seamless pipe is a long strip of steel with a hollow cross-section and no seams around it. The thicker the wall thickness of the seamless pipe, the more economical and practical it is. The thinner the wall thickness, the greater the processing cost of the seamless pipe. Seamless pipes include seamless pipes for fluid transportation, seamless pipes for structures, seamless pipes for petroleum cracking, and seamless pipes for ships.

[0004] However, when the existing seamless pipe is used, the seamless pipe will be subjected to external pressure. When the pressure on the seamless pipe is too large, the surface of the seamless pipe will bend. The bending will cause cracks or breakage in the seamless pipe, which will have a certain impact on the service life of the seamless pipe. Therefore, a bending-resistant seamless pipe is provided. Utility Model Content
