1. Flame cutting and gas cutting simply do not work. The end of the pipe must be discolored, and the melting points of the oxides of chromium-nickel stainless steel, aluminum and aluminum alloys are all higher than the melting point of the material itself, so it is impossible to cut with oxygen at all. Large diameter plastic coated steel pipe

2. Carbon arc air gouging Carbon arc air gouging refers to the method of using graphite rods or arcs generated between carbon rods and the workpiece to melt the metal and blow it off with compressed air to realize the processing of grooves on the metal surface. Carbon arc has smoke, dust pollution and arc radiation. Many metal residues after melting and cooling are attached to the inner wall, which is difficult to eradicate.

3. Wire cutting and fast wire cutting can meet the cutting quality requirements. However, it should be noted that the color of the pipe end line will change after being cut, and it needs to be polished. The slow speed is unbearable, and the small production volume can be considered. No investment is required for outsourcing processing. The speed is slow and the batch is small.

4. Turn on the cutting wheel of the grinding wheel (collaborative automatic steel pipe end burr eradication machine). After cutting with an ordinary grinding wheel, there will be burrs and hanging flashes. The use of the automatic stainless steel pipe end burr eradication machine can achieve Very good application effect, low cost, only the consumption of grinding wheel is a bit large, suitable for use when the quantity is small.
