[0002] Steel pipe is a pipe made of steel with a hollow cross-section. The steel plate is bent into a circle and welded to form a steel pipe. After welding, a weld will be formed on the surface of the steel pipe. A grinder is needed to grind the weld to make the surface of the steel pipe flat.
[0003] After searching, the prior art (publication number: CN111590423A) is a stainless steel pipe weld grinding device, which states that "it includes a base, support plates are fixedly connected to the top of the left and right ends of the base, a clamping mechanism for fixing the stainless steel pipe is arranged on the inner side of the support plate, a grinding mechanism is arranged between the support plates on both sides, and the grinding mechanism is connected to the base through a support mechanism with an adjustment function."
