Production process of precision stainless steel capillaries

 1. Raw material selection:
    - Mainly use stainless steel materials such as 316L and 304L. These materials contain more chromium (Cr) and nickel (Ni) elements, ensuring the corrosion resistance and strength of the products.
    - Consider chemical composition, accuracy requirements and surface condition when selecting materials.

2. Pipe making process:
    -Cold drawn pipe process: Through multiple cold rolling and drawing processes, the hot-rolled plate is gradually turned into a small diameter pipe.
    - Hot pressed tube process: Utilize the plasticity of the material to produce capillary tubes with thin walls and smooth surfaces through metal pressing in a hot state.
    - Cold drawing pipe making process: requires high accuracy of material cross-sectional area and circumference, which depends on the impact of organizational structure and performance.

3. Surface treatment:
    - The purpose is to reduce scale and improve surface finish and corrosion resistance.
    - Common surface treatments include pickling, mechanical polishing and electric rust removal.

Longyu 304 Stainless Steel Capillary Seamless Steel Tube China Suppliers
4. Detection:
    - As precision mechanical parts, capillary tubes must undergo strict testing and quality control.
    - Testing methods include metallographic testing, mechanical performance testing and ultrasonic testing to ensure that the internal structure and physical properties of the product meet standards.

5. Special process:
    - Annealing: Solution heat treatment process to improve corrosion resistance and eliminate work hardening.
    - Annealing conditions: including reaching the required temperature range (1040~1120°C), using pure hydrogen as the annealing atmosphere, maintaining the sealing of the furnace body, maintaining positive air pressure, and ensuring a dry state in the furnace.

6. Processing technology:
    - Stainless steel capillary tubes can be subjected to various finishing processes such as edge milling, rolling, punching, closing, hole making, surface grinding, flaring, shrinking, bending, etc.
7. Measurement and inspection:
    - Measure the outer diameter, inner diameter, wall thickness, straightness, length, and check that there are no cracks and pits on the pipe surface, and conduct a surface roughness test.

8. Applied research:
    - High-purity 304 stainless steel precision tube capillary tubes are widely used in fields such as microfluidic technology, fiber optic sensors, and liquid chromatography technology.

9. Development prospects:
    - With the development of technology, the demand for high-purity stainless steel precision tube capillary tubes will further increase, especially in fields such as biomedicine, environmental monitoring, and chemical analysis. The entire production process requires extremely high precision and quality control to ensure the high performance and long life of the stainless steel capillary tubes.
