What is a stainless steel capillary tube, and what are its applications?

A Stainless Steel Capillary Tube is a small, narrow, and cylindrical tube made from a corrosion-resistant alloy. These tubes are characterized by their precise and uniform dimensions, typically with an outer diameter ranging from a few millimetres to sub-millimetre sizes. The inner diameter of capillary tubes is significantly smaller, allowing for the controlled flow of liquids or gases.

Stainless steel capillary tubes find extensive applications across various industries due to their unique properties. In the medical field, they are used for precise fluid delivery in applications such as blood sampling, drug delivery systems, and chromatography. Their small size and excellent corrosion resistance make them ideal for analytical instruments like gas and liquid chromatography.

In the automotive and aerospace industries, stainless steel capillary tubes are crucial in fuel injection systems, hydraulic lines, and brake systems. These tubes offer high strength, resistance to extreme temperatures, and durability, making them suitable for harsh operating conditions.

What are the advantages of using stainless steel capillary tubes compared to other materials in various industries?

Stainless steel capillary tubes offer several advantages over other materials, making them a preferred choice in various industries. Stainless steel is known for its exceptional corrosion resistance. This property ensures the longevity and durability of capillary tubes, even in highly corrosive environments, such as chemical processing plants or offshore oil rigs.

Stainless steel capillary tubes exhibit high strength and durability, enabling them to withstand mechanical stress, pressure, and temperature variations. This characteristic is particularly valuable in automotive, aerospace, and oil and gas industries, where the tubes may encounter challenging operating conditions.

Another advantage is the dimensional accuracy of stainless steel capillary tubes. They can be manufactured with precise outer and inner diameters, producing consistent and reliable performance. This precision is crucial in applications such as medical devices, analytical instruments, and fluid control systems, where precise measurements and controlled flow are necessary.

Stainless Steel Capillary Tubes also possess excellent thermal conductivity, which is advantageous in applications requiring efficient heat transfer, such as electronics and automotive industries. Additionally, stainless steel is non-reactive, ensuring the purity and integrity of fluids or gases passing through the tubes remain unaffected.

Capillary Stainless Tube Manufacturing Process

Welding Process

The grade and application requirements have an impact on tube welding and forming. For the manufacturing of tiny diameter tubes, we employ TIG welding. Steel sheets are coiled and welded inside of a welding machine. The steel sheets are shaped into a coil before entering the machine. The seam between these coils is then welded to create a tube.

Drawing/ Floating Process

Pulling a metal bar, rod, or wire through the entirety of a die to change its finish, shape, size, and/or mechanical qualities is known as floating or drawing. The tube's outer, inner, and wall thicknesses are all reduced via the tube drawing procedure. Stainless steel tubes benefit from maintaining the integrity of their surface.

Continuous Seamless Tube Mills

The production of seamless tubes has been transformed by continuous tube mills. These mills do away with the necessity for forging welding or filler metal, in contrast to conventional procedures. With the use of this technology, seamless pipes and tubes may be produced continuously, increasing productivity while lowering costs and improving efficiency.

Continuous Casting

A notable advancement in the production of seamless tubes is continuous casting. The metal is solidified into a continuous billet through the continuous pouring of molten metal into a water-cooled mould. Better uniformity and enhanced mechanical qualities are guaranteed by this continuous casting technique for the tubes.

Annealing

Metal is heated above the point of re-crystallization and cooled to room temperature during the annealing process. The molecular bonds in metal tighten when it is shaped, making it rigid. The metal is put through an annealing process to regain its ductility.

Sinking Process

Tube sinking is a drawing technique that reduces the diameter of tubes. In this drawing technique, a tube is run through a die without the need of a mandrel. Good inner surface quality is not ensured when using a mandrel. The die angel determines the integrity of the outer surface. The die being used produces a uniform surface. A tube can be significantly smaller than it was originally. When cost is a factor, tube sinking is ideal.

Inspection and Testing

Before sending our items to our consumers, we conduct inspection procedures to verify their integrity.
