Capillaries, also called microtubules or microcapillaries, are small diameter tubes with precise dimensions. They are widely used in different applications across various industries, from medical and scientific instruments to automotive and electronics. Among the different materials used for manufacturing capillary tubes, stainless steel stands out for its excellent properties. In this article, we will explore the types of stainless steel capillary tubing available on the market.
1. Seamless stainless steel capillary tube:
Seamless stainless steel capillary tubes are made by perforating blanks or hollow bodies and then extruding them. The advantages of seamless pipes are uniformity and smoothness both internally and externally. They offer excellent corrosion and temperature resistance and are suitable for applications involving corrosive liquids or extreme conditions.
2. Welding stainless steel capillary tube:
Welded stainless steel capillary tubes are manufactured by forming stainless steel strips or coils into a tube shape and then welding the edges together. Welding can be done using different methods, such as TIG (tungsten inert gas) welding or laser welding. Welded pipe is cost-effective and available in a variety of sizes and wall thicknesses.
3. Electrolytic polished stainless steel capillary:
Electropolishing is a process used to remove surface defects from stainless steel pipes, resulting in a smooth, bright and highly reflective surface. Electropolished stainless steel capillary tubes are ideal for applications where cleanliness and hygiene are critical, such as the pharmaceutical or food industry. Smooth surfaces also help minimize flow resistance and increase fluid flow rates.
4. Stainless steel spiral capillary tube:
Stainless steel spiral capillary tubes are made by winding long strips of stainless steel into spiral coils. The coiling process allows for flexibility and ease of installation, making it suitable for applications that require bent or curved tubes. Spiral capillary tubes can be used in heat exchangers, cooling systems and refrigeration.
5. Nano-sized stainless steel capillary tube:
Nano-sized stainless steel capillary tubes are tubes with extremely small diameters, usually in the nanometer range. These tubes are used in cutting-edge applications such as nanofabrication, microfluidics, and lab-on-a-chip devices. They play a key role in precisely controlling fluid flow and improving chemical and biological analysis at micron and nanoscales.
In summary, stainless steel capillary tubes are available in different types to meet different applications and requirements. Whether seamless, welded, electropolished, rolled or nano-sized, the choice of type depends on factors such as corrosion resistance, temperature resistance, surface finish, flexibility and dimensional accuracy. Understanding the different types of stainless steel capillary tubing can help engineers and designers choose the one best suited for their specific application, ensuring optimal performance and durability.
