Mirror pipe stainless steel
Advantages
Mirror stainless steel pipe has a surface of the highest quality polished to a mirror shine, which does not allow the adhesion of dirt. The smallest defects are visible on it. The electropolished surface has a higher Fe/Cr ratio, which increases anti-corrosion resistance. Mechanical strength increases due to reduction of stress concentrations. The highest resistance has high-alloys with high content of nickel, copper, molybdenum, silicon. Alloy grade with the necessary set of properties is selected depending on specific conditions (concentration of aggressive factor, operating temperature). Auremo supplier guarantees high quality of mirror stainless steel pipe in accordance with GOST and international standards.
Disadvantages
Mirror pipe (welded by means of HF welding) cannot be used in medical, food industries, as well as in pressurized pipelines due to its untreated inner wall.
Manufacturing
Mirror stainless pipes are made of steel grades - 316 AISI, 304 AISI (in limited positions) according to standards: DIN 72 263, DIN 17 457. DIN 722 263 standardizes the quality of pipes produced by high frequency HF-welding of strips (stainless steel strip). HF welding speed is up to 40 m/min, which significantly reduces the cost of the product. Although these pipes are almost ideal for welded constructions, they are not suitable for the food industry. Although they cost a third less than TIG welding, the HF weld seam is 20% less strong than the base material.
Treatment
Welding - TIG (Tungset Inert gas) gives one hundred percent strength to the weld, 25 mm thick. The weld is flush according to DIN 17 457. The seam is as smooth as heat treated steel. For the food industry, the inner seam must undergo additional finishing sanding. Mirror stainless pipe of the type SS according to DIN 11 850 can undergo heat treatment (light annealing), grinding treatment, chemical treatment (pickling).
The machined surface of the pipes | Grinding cleanliness, μm. |
---|---|
internal weld surface | 1,6 |
Outer surface of pipes | less than 1.0 |
Main tube material | 0,5 - 0,8 |
Mirror pipes are ground with grinding units, the number of brushes is at least 5, usually 6) with the use of polishing paste on 1-2 end brushes. The grit size for grinding should be 600 grit or more. The inside (and outside) can be polished using the electrochemical method, also known as the "alternating cladding process" or "chemically treated process", which is much more effective than conventional mechanical polishing. Electropolishing smoothes out defects and gives the steel a mirror-like shine. The correct ratio of current and electrolyte temperature makes it possible to selectively remove defects by increasing the electric current density, thus producing a completely smooth surface.
Applications
The luster of polished tubes looks very attractive. They are popular when decorating offices, bars, shopping malls, residential buildings. Their aesthetics are also important in sanitary (e.g. sewage systems).
