Anti-corrosion
spiral steel pipe is made of low-carbon structural steel rolled into a tube blank according to the relative helix angle, and then the pipe seams are welded together. It is also called spiral steel pipe or spiral welded pipe. Anti-corrosion spiral steel pipe manufacturers will produce slag inclusions, for what reason?
The first thing to consider is whether it is caused by more impurities in the raw materials. The raw materials include base metal, welding wire, flux, etc., and all possible causes of slag inclusions. Then the welding process parameters selected are inappropriate, which is not conducive to the formation of slag. Floating out leads to the appearance of slag inclusions; the cleaning between layers is not clean during multi-layer welding, which is also the cause of slag inclusions in the production of anti-corrosion spiral steel pipes.
To sum up, whether it is the selection of raw materials or the welding process, strict inspection by QC personnel is required to ensure the high-quality output of anti-corrosion spiral steel pipes
