Stainless steel 304 capillary tubes are a particular type of tube that is used in a variety of measurement applications. Due to their heavier wall construction and typically lower sizes, these high-precision measurement tubes are appropriate for use as nuclear reactor components in the aerospace sector. A tube with a very small internal diameter is a 304 capillary made of stainless steel. It has a very long length and is coiled into multiple turns to take up less room. The internal diameter of the Stainless Steel 304 Capillary Tubes is calibrated, and the length is used to regulate the refrigerant flow. Additionally, it links the thermostatic expansion valve to the remote bulb or the other way around.

The benefits of capillary 304 stainless steel tube include good corrosion resistance, heat resistance, softness, tight tolerances, rust resistance, ability to support heavy loads, and ease of cleaning. Because stainless tube is lighter than its comparable bar shape, it is more useful for use in fabrication when weight is an issue. Oil, grease, and other material are not present on the tubes' interior surface. This guarantees, for instance, that liquids and gases flow optimally and uniformly from the sensor to the measurement device.

Features:

Capillary Tube is a long, narrow tube of constant diameter. The word "capillary" is a misnomer since surface tension is not important in refrigeration application of capillary tubes.

Exceedingly demanded in precise apparatus or instruments,automatic instruments,eletronic parts,oil or gas plants and other industries.

Stainless Steel Tube is a good choice for most applications due to greater corrosion resistance and precision.

Alloy 304 stainless steel is one of the most common stainless steel and it is having nickel and chromium alloy metal as non-iron constituents.

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.

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.
