Polishing Stainless Steel Tubing Definition

Stainless steel pipe polishing process is actually the inside or outside surface of the pipe polishing process, using polishing equipment and the friction of the pipe’s surface, to meet the roughness requirement.

Polishing Tubing Surface Grade

Outside surface of 240 Grit, 400 Grit, 600 Grit, 1000 Grit, Mirror, Brushed , Silk hair

Polishing Tubing Advantages

  • Greatly improved corrosion resistance. ​Electropolishing selective dissolution of the elements, making a solid surface of chromium-rich layer of dense solid transparent membrane, and formation of electric surface, eliminating and reducing micro-cell corrosion.
  • Micro-electrolytic polished surface are is more smooth than mechanical polishing, reflecting a higher rate. This makes the device non-stick wall, not hanging material, easy to clean surface with a reduction of approximately one wire, to GMP and FDA regulatory requirements .
  • Electrolytic polishing from the workpiece size and shape restrictions. Mechanical polishing on the appropriate implementation of the workpiece can be polished, for example, thin tube wall, elbow, bolts, nuts and containers inside and outside the wall.

Polishing Stainless Steel Tubing Procedure

Electro-polishing EP and Mechanical Polishing MP. Electro polishing is the use of stainless steel in the electrolyte solution in the selectivity of the anode to achieve the purpose of polishing and cleaning the surface of a surface treatment .

Electro polishing is superior than mechanical polishing :

  • A. a surface potential conditions,
  • B. difficult to capture pollutants,
  • C. surface can form a more solid salt corrosion resistance of the transparent membrane,
  • D. does not produce Beillby layer.

Electrochemical Polishing Characteristics

Electrochemical polishing is the use of electrochemical anodic dissolution of metal grinding polishing principle. The electrochemical pre- polishing and fine polishing machine together organically, playing two types of electrochemical polishing expertise and institutions. It is not material hardness and toughness of restrictions , complex shapes can be polished workpieces. The method and electrolytic grinding are similar .

Polishing Stainless Steel Tubing Type

Stainless steel tube of polishing with internal surface polishing and external polishing; Dry Bright and Wet Bright.

Polishing Tubing Difference between Wet bright and Dry Bright

Grinding resistance: light resistance and abrasive grinding machinery, the rigidity of the workpiece support system , but also with grinding in the grinding temperature, vibration , or a relationship , but also affect the life of grinding tools , grinding the surface of the characters .

Polishing Tubes Grinding temperature

Grinding thermal deformation temperature would reduce dimensional accuracy , surface grinding process also affected the metamorphic layer

Polishing Stainless Steel Tubing Application

Mechanical treatment, Mechanical working, Tool, CNG, Automobile engine, Decoration.
