Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe sealing technology, and in particular to a surface treatment device for a spiral pipe joint. Background Technology
[0002] Spiral pipe, also known as spiral steel pipe or spiral welded pipe, is made by rolling low-carbon structural steel or low-alloy structural steel strip into a pipe blank at a certain spiral angle (called the forming angle) and then welding the pipe seam together. It can produce large-diameter steel pipes with narrower steel strips.
[0003] In the use of spiral pipes, multiple pipes are usually welded together to extend their service life. The weld joints between adjacent pipes are usually cleaned manually after welding to remove the weld slag. This method is inefficient in cleaning the weld slag on the pipe surface, requires a lot of manpower, and is costly. Manual cleaning of the weld slag on the pipe surface is not thorough. The high temperature of the pipe surface after welding can cause injury to workers. In addition, workers can inhale harmful gases left over from welding during the cleaning process, which can affect their respiratory system.
