The role of the tube machine in the work is getting more and more attention, what is the main role of the tube machine? Let's take a look at it below.
The main role of the pipe machine
Pipe-making machines are mainly divided into two categories: the most common high-frequency pipe welding machine, and the other is stainless steel pipe machine. The high-frequency pipe welding machine is mainly used to produce various iron pipes, water pipes, etc. produce.
Stainless steel pipe machine is mainly used to produce various stainless steel decorative products such as stainless steel decorative pipes, such as: stair handrail pipe, anti-theft door and window pipe, stair handrail pipe, guardrail, etc., can also produce various car exhaust Tube, heat exchanger tube, fluid tube, edible tube, etc.we are tube mill manufacturer,you can know it.
Pipe machine: stainless steel rust reasons
1. The surface of stainless steel adheres to acid, alkali, and salt substances (such as alkali water and lime water sprayed on the wall) to cause local corrosion.
2. The stainless steel pipe is a steel pipe that does not produce rust in a weak corrosive environment such as the atmosphere and fresh water, and the chromium content in the steel must be ≥12%. If the chromium content is low or not in a weakly corrosive environment such as the atmosphere (including in a weakly corrosive environment such as the atmosphere, but under Cl-local rich enrichment conditions), rust will be produced.
3. The surface of the stainless steel accumulates the dust or other metal particles attached to other metal elements. In the humid air, the condensed water between the attached material and the stainless steel connects the two into a micro battery, which triggers the electrochemical reaction. The protective film is destroyed, which is called electrochemical corrosion.
4, in the polluted air (the atmosphere containing a large amount of sulfides, oxides, hydrogen oxide), in the case of condensed water, the formation of nitric acid, acetic acid liquid point, causing chemical corrosion.
5. The surface of the stainless steel adheres to the organic juice, which forms an organic acid in the presence of water and oxygen, and forms an organic acid on the metal surface for a long time.
