Stainless steel capillary pipe and tube are thin-walled, high-precision pipes commonly used in industries requiring high-performance materials for critical applications. These pipes are manufactured from austenitic, ferritic, and martensitic grades of stainless steel, with the most common being 304 and 316 stainless steel due to their excellent corrosion resistance, strength, and durability.

Capillary pipes are typically used in applications involving fluid and gas transport, heat exchangers, instrumentation, medical devices, and laboratories. Their small diameter (usually less than 6mm) allows for precise control over the flow of materials, making them suitable for high-pressure and high-temperature conditions. Due to the thin walls and high accuracy, they are ideal for industries that require tight tolerances, such as pharmaceutical manufacturing, chemical processing, and food industries.

The corrosion resistance of stainless steel capillary pipes makes them highly reliable in challenging environments, including exposure to acidic or alkaline substances. This ensures their longevity and minimizes the risk of contamination, which is particularly important in industries such as healthcare and food processing. Furthermore, stainless steel’s inherent strength and resistance to oxidation enhance the performance of capillary tubes in harsh environments.

The fabrication process of stainless steel capillary pipes involves cold drawing and precision machining, which provides a smooth surface finish and uniform wall thickness. These properties make them suitable for welding, bending, and forming without compromising their mechanical properties.
