In the actual production of cold-drawn steel pipes, it is often affected by various factors. That is to say, the defects caused by cold drawn steel pipes are often caused by the combined effect of several factors. For example, a narrow V-shaped mouth does not necessarily produce peroxide oxides, unless the extrusion amount is slightly smaller than the normal requirement.
If the amount of extrusion is too small, it may be caused by the slightly narrow slitting width of the steel strip, or the wear of the tooling, and the improper installation of the equipment. In addition, the welding defects of cold-drawn steel pipes are also caused by reasons other than the welding area. For example, cold welding may be caused by the cavitation (evacuation) phenomenon of the cooling pump, which cannot fully cool the magnetic rod, and the magnetic rod becomes hot instantly. In this way, the effect of the current concentrated in the V-shaped port will be weakened, the current will be conducted along the back of the steel pipe, the heat of the V-shaped port will be reduced, and cold welding will occur.
There are many processes for cold-drawn steel pipe processing, and these different processes have different left and right. Processing such as mirror polishing, brushed surface, etc. is to make the surface of the guardrail more beautiful.
Cold-drawn steel pipes can be combined with solar photovoltaic power generation systems, solar vacuum tubes, etc. during processing. This processing technology can make cold-drawn steel pipes have the effect of solar energy, and because of the strong mechanical properties and corrosion resistance. The stainless steel is the raw material, so the service life will be longer.
When the cold-drawn steel pipe is processed, the structure of the elbow at the turning position of the main surface pipe must be smooth and without traces. In addition, the stainless steel pipe fixed on the ground should also be kept perpendicular to the main surface pipe, because the hardness of stainless steel is relatively large. If there is a certain angle, it may affect the subsequent installation. There are also vertical stainless steel pipes that should be kept parallel to this time to minimize errors in spacing.
