Description

Technical Field

[0001] The utility model relates to the field of steel pipe processing, in particular to a steel pipe which is convenient for butt connection. Background Art

[0002] Stainless steel pipe is a kind of pipe with corrosion resistance, mainly composed of iron, chromium, nickel and other elements. Stainless steel pipe has the advantages of high strength, high corrosion resistance, high temperature resistance, low temperature resistance, etc., and is widely used in petroleum, chemical, pharmaceutical, food, machinery, construction and other fields. According to different manufacturing processes and uses, stainless steel pipes can be divided into many categories, such as seamless stainless steel pipes, welded stainless steel pipes, precision stainless steel pipes, industrial stainless steel pipes, decorative stainless steel pipes, etc.

[0003] After searching, the Chinese patent announcement number is: CN219755674U. The utility model relates to the technical field of stainless steel pipes, and discloses a stainless steel pipe that is convenient for docking, including a stainless steel pipe 1 and a stainless steel pipe 2. The stainless steel pipe 1 is provided with a flange ring 1 at one end close to the stainless steel pipe 2, and the stainless steel pipe 2 is provided with a flange ring 2 at one end close to the stainless steel pipe 1. The side wall of the flange ring 1 is fixedly connected with a clamping assembly, and the flange ring 1 and the flange ring 2 are abutted, and then the fixed block is inserted into the card groove of the side wall of the clamping member, and the flange ring 1 and the flange ring 2 are clamped by the cooperation of the limit block and the clamping member. The spring 1 pushes the limit rod to clamp the limit rod with the limit groove set on the end face of the fixed block, so as to conveniently dock the flange ring 1 with the flange ring 2. Press the slide bar 2 to push the slide bar 1 to release the clamping connection with the through hole of the side wall of the slide groove, and the spring 2 pushes the block to block the groove, and the magnet attracts the two blocks together to prevent the accidental pulling of the limit block from causing the flange ring 1 and the flange ring 2 to be accidentally separated.
