Product Details
The processing technology of stainless steel capillary tubes in Shaanxi mainly includes the following steps.5:
- Material preparation. :
Select suitable stainless steel materials.1.
Cut and clean the materials according to requirements.1.
- Cold drawing processing. :
Place the stainless steel material into the cold drawing machine.1.
Achieve the required diameter and wall thickness through multiple draws.1.
- Precision processing. :
Includes cutting, grinding, polishing, and other processes.1.
Ensure the surface quality and dimensional accuracy of the tubes.1.
- Surface treatment. :
Includes gas shielded welding, pickling passivation, bright annealing, cold drawing, etc.3.
Gas shielded welding protects the surface from oxidation.3.
Pickling passivation forms a passivation film to improve corrosion resistance.3.
Bright annealing eliminates internal stress and reduces stress corrosion.3.
- Cleaning treatment. :
Remove oil and impurities from the surface.1.
Ensure the purity and corrosion resistance of the tubes.1.
- Testing. :
Includes appearance inspection, dimensional testing, chemical composition analysis, etc.1.
Ensure the tubes meet the requirements.1.
- Special processing. :
Includes welding forming, tip processing, diameter reduction, expansion, grooving, etc.2.
Welding forming may use techniques such as argon arc welding.2.
Tip processing can use cold shrink or hot shrink techniques.4.
Expansion and reduction processes change the tube diameter.6.
- Cutting processes. :
Includes mechanical cutting, manual cutting, laser cutting, shearing, etc.7.
Choose the appropriate cutting method based on the tube diameter and wall thickness.1.
- Other processing. :
Such as bending, drilling, etc.6.
Bending is divided into hot bending and cold bending.6.
Drilling can be manual or automatic.4.
These processes ensure the quality, precision, and stability of stainless steel capillary tubes, while also improving their service life.3.
