The cutting processing technology of stainless steel pipe
Without influence on the surface of the stainless steel pipe, how to quickly cut stainless steel pipe? One way is to use a grinding wheel cutting, this is now use most a way of cutting, is actually with grinding wheel as the cutting tools for cutting stainless steel pipe, this way of cutting cost is the cheapest, but it is easy to produce many burrs after cutting, lead to later also need to add deburr process, if there is no requirement, some manufacturer of burr then this method is one of the most practical, the lowest cost.
There is a kind of method is thread cutting, namely the stainless steel capillary progresses in wire-cutting machine wire walking, but it’s important to note that this method will result in color stainless steel pipe cutting, if strict in product manufacturers, so also need through post processing, such as polishing grinding to the secondary processing.
Another method is to use a metal disk saw cutting, using the cutting method for cutting of stainless steel pipe incision is very good, and it also can cut a few root together, so there is also a very good machining efficiency, but the downside is that chip easy to stick the cutting tool, therefore in choice of saw blade must be especially careful.
Fourth method is to use gear hob chipless cutting machine cutting, the basic method of cutting out of stainless steel pipe incision is perfect, is the choice of many manufacturers, but it’s important to note that this method is not suitable for cutting wave than stainless steel pipes, because it is easy to form the tear, lead to deformation of stainless steel pipe.
There are two kinds of stainless steel pipe, seamless steel pipe and welded pipe. At present more advanced cold working of the seamless steel pipe production process was followed by circular pipe billet heating, perforation (hot rolled) wall thickness, appearance, surface and high precision DuHuang pipe, 1 to 2 times cold drawn or cold rolled, protective atmosphere heat treatment, nondestructive testing online. This type of seamless steel pipe processing are mainly distributed in the south China sea, shunde, dongguan, guangdong Lan stone, in wenzhou, zhejiang province, jiangyin, jiangsu, Shanghai, tianjin and other regions. Thousands of XingHua port of stainless steel seamless pipe is mainly used in chemical, fertilizer, chemical fiber, petrochemical, electric power, nuclear industry, aerospace and aviation, etc. And welded pipe is made of stainless steel plate with welded pipe.
The use areas of Stainless steel pipes are mainly urban landscape engineering and architectural decoration engineering, in light industry, pharmaceutical, paper making, sewage disposal and water supply engineering and other fields, there are also a significant proportion in the field of chemical, fertilizer, petrochemical and other general selection specifications in to more than 159 mm in the low pressure pipeline, the field of automobile muffler is also the use of stainless steel welded pipe. pipe billet production, are generally choose required thickness of the plate or strip, after the drum with special welded butt welding. Has the quality of the pipe billet, directly depends on the board (with) material quality and welding quality. In general, it is easier to control the wall thickness tolerance.
