Manufacturing Process of SS Capillary Tubes

Material Selection

The process begins with the selection of high-quality stainless steel, typically grades like 304, 316, or 321, known for their superior properties.

Tube Drawing

The stainless steel is drawn through a die to create a tube with the desired outer diameter. This process involves multiple stages of drawing and annealing to ensure precision and consistency.

Annealing

Annealing is a heat treatment process that softens the metal, improving its ductility and reducing hardness, which is essential for further processing.

Cold Drawing

Cold drawing involves pulling the tube through a die at room temperature, refining the tube’s diameter and improving its surface finish.

Cleaning and Inspection

The tubes undergo rigorous cleaning to remove any residues or impurities. Inspection follows, using techniques like ultrasonic testing and eddy current testing to ensure the tubes meet strict quality standards.

Cutting and Finishing

Finally, the tubes are cut to the desired lengths and finished to meet specific application requirements. This step may also involve polishing to enhance the surface quality.

Advantages of Using SS Capillary Tubes

Longevity and Durability

Due to their resistance to corrosion and wear, SS capillary tubes have a long service life, reducing the need for frequent replacements.

High Precision

The precise internal diameter of SS capillary tubes ensures accurate fluid and gas flow, which is critical in applications like medical devices and analytical instruments.

Versatility

SS capillary tubes can be used in a wide range of applications, from medical to industrial, due to their adaptability to different environments and requirements.

Safety

In high-pressure applications, the mechanical strength of SS capillary tubes provides a safety margin, preventing failures that could lead to hazardous situations.

Selecting the Right SS Capillary Tube

Consider the Application
