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

A Stainless Steel Needle Tube is a specialized type of tubing made from stainless steel characterized by its small diameter and thin walls. These tubes are precisely engineered to have a hollow, cylindrical shape with a narrow internal diameter similar to a needle's. The high-quality stainless steel manufacturing process ensures excellent durability, corrosion resistance, and strength.

Stainless Steel Needle Tubes find diverse applications in various industries due to their unique properties. In the medical and healthcare sectors, these tubes are commonly used in diagnostic and therapeutic procedures, such as blood sampling, intravenous therapy, and catheterization. Their small size and precise dimensions make them suitable for delivering medications or extracting fluids with minimal discomfort to the patient.

Moreover, scientific research and laboratory settings utilize stainless steel needle tubes. They are crucial in precision instrumentation, chromatography, and gas analysis applications. Additionally, these tubes are employed in industrial sectors, including automotive, aerospace, and electronics, where they serve as conduits for fluids, gases, or electrical wiring in compact or tight spaces.

What are the key properties and advantages of using stainless steel needle tubes?

Stainless steel needle tubes possess several key properties and offer numerous advantages that make them highly desirable in various applications. These tubes exhibit exceptional corrosion resistance, thanks to chromium in stainless steel. This corrosion resistance ensures the longevity and reliability of the needle tubes, making them suitable for use in harsh and corrosive environments.

Stainless Steel Needle Tubes have excellent mechanical strength and durability. The inherent strength of stainless steel allows these tubes to withstand high pressures, making them ideal for applications that involve transporting fluids or gases under significant pressure. Additionally, their durability ensures minimal risk of deformation or breakage, ensuring consistent performance over time.

Furthermore, stainless steel needle tubes offer precise dimensions and tight tolerances. The manufacturing process ensures accurate inner diameters and thin walls, enabling precise and controlled delivery of fluids or extraction of samples. This level of precision is critical in medical, laboratory, and industrial applications where accuracy and reliability are paramount.

Needle 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.
