Description

Technical Field

[0001] This invention belongs to the field of steel pipe cleaning technology and relates to a steel pipe outer wall cleaning device, specifically an adaptive multi-diameter stainless steel pipe outer wall cleaning device. Background Technology

[0002] Seamless steel pipe is a type of hollow steel pipe with large diameter and thin wall. Due to its excellent corrosion resistance, high temperature resistance, low temperature resistance, and oxidation resistance, it is widely used in various industries such as petroleum, chemical, energy, and food. Seamless steel pipe is made from steel ingots or solid billets through piercing to form a rough tube. The cold rolling (drawing) manufacturing process includes: solid billet → heating → piercing → heading → straightening → annealing → pickling → oiling (copper plating), etc. Pickling is an essential process for cold-rolled stainless steel pipes. The main purpose of pickling is to remove the iron scale (oxide layer) formed on the surface of the steel pipe during hot rolling and annealing, and to passivate the surface, improving the corrosion resistance of the steel pipe. However, if residual acid, dirt, and residual oxides are not removed from the surface of the stainless steel pipe after pickling, it will accelerate the corrosion of the steel pipe, reducing its quality and service life.

[0003] After pickling, most seamless steel pipes are typically rinsed manually with a handheld high-pressure water gun at close range, relying on visual inspection of the surface cleanliness of the stainless steel pipe. This process is repeated several times. This method has the following main problems:

[0004] 1) When manually rinsing stainless steel pipes, workers need to hold a high-pressure water gun and come into close contact with the pickled pipes. Because the working environment is not enclosed, the acid mist and residual acid produced may come into direct contact with the workers, seriously threatening their personal safety.

[0005] 2) The steel pipes to be rinsed come in a variety of sizes. When rinsing manually, workers operate water guns and rely on visual inspection to determine whether the rinsing is clean. Ordinary rinsing equipment on the market can only be used with steel pipes of specific sizes, which can easily lead to a waste of water resources and does not guarantee the rinsing quality.

[0006] 3) During the cleaning of the outer wall of the steel pipe, due to its large size and weight, after the worker cleans one side, he needs to use a rope to rotate the steel pipe, which will inevitably cause the steel pipe to bump and affect its surface quality. It may also cause the steel pipe to slip and roll, which poses a certain safety hazard to the workers. Summary of the Invention

[0007] In response to the problems and needs existing in the background technology, the present invention proposes an adaptive multi-diameter thin-walled stainless steel pipe outer wall cleaning device.
