Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipes, in particular to a seamless stainless steel pipe. Background Art

[0002] Stainless steel seamless steel pipe is a long strip of steel with a hollow cross-section and no seams around it. It is resistant to corrosion by weak corrosive media such as air, steam, and water, and chemically corrosive media such as acids, alkalis, and salts. It is also called stainless acid-resistant steel pipe. Due to its excellent material properties, it can be used as a transmission pipeline and is widely used. However, some of the current stainless steel seamless steel pipes need to be butt-jointed and installed through connecting flanges when they are partially connected. During installation, the flanges need to be aligned first, and the bolt holes on the two flanges need to be aligned before the bolts are inserted one by one, and then the bolts are tightened and fixed one by one. This installation method is not only very time-consuming and laborious to operate, but also requires the use of operating tools to slowly install it, which is extremely time-consuming. In addition, when the pipeline is disassembled later, it also needs to be disassembled one by one. The overall disassembly and assembly operation of the structure is relatively cumbersome, which makes the butt-joint installation of the steel pipe lack of convenience and affects the butt-joint installation efficiency of the overall pipeline.
