In the realm of precision engineering, stainless steel capillary tubes stand out as indispensable components. Manufactured with meticulous attention to detail, these tubes offer unparalleled accuracy and reliability across various industries. At Jianglin, we pride ourselves on producing high-quality stainless steel capillary tubes tailored to meet the specific needs of our clients.
What Are Stainless Steel Capillary Tubes?
Stainless steel capillary tubes are slender, hollow cylinders with exceptionally small inner diameters, typically ranging from 0.1mm to 3mm. Despite their diminutive size, they exhibit remarkable strength and resilience, owing to the robust nature of stainless steel. These tubes are engineered to maintain consistent internal dimensions throughout their length, ensuring precise fluid flow control and measurement.
Chemical Composition and Mechanical Properties
The performance of stainless steel capillary tubes is largely determined by the specific grade of stainless steel used. Common grades include 304, 316, and 321, each offering distinct advantages:
Grade 304: Known for its excellent corrosion resistance and formability.
Grade 316: Offers superior resistance to corrosion, especially in chloride environments.
Grade 321: Provides enhanced resistance to high temperatures and oxidation.
These grades ensure that the capillary tubes can withstand various environmental conditions, maintaining their integrity and performance over time.
Manufacturing Process of Stainless Steel Capillary Tubes
The production of stainless steel capillary tubes involves several precise steps:
Material Selection: High-quality stainless steel is chosen to ensure durability and resistance to corrosion.
Tube Formation: The selected material is processed into thin-walled tubes through extrusion or pilgering.
Drawing Process: The tubes are drawn through dies to achieve the desired diameter and wall thickness.
Annealing: Heat treatment is applied to relieve internal stresses and enhance mechanical properties.
Surface Finishing: The tubes undergo polishing or passivation to achieve a smooth, corrosion-resistant surface.
Throughout each stage, stringent quality control measures are implemented to ensure the final product meets the highest standards of precision and reliability.
