Product Description

Features of Stainless Steel Precision Tubes:

1. High Precision:
   Wall thickness and outer diameter have extremely high accuracy, with tolerances typically controlled within ±0.05mm or even smaller.

2. Excellent Surface Finish:
   Inner and outer surfaces are polished or pickled, providing superior surface quality with smooth, oxide-free inner walls.

3. Good Mechanical Properties:
   Due to cold working, the tubes exhibit high strength along with good plasticity and toughness.

4. Diverse Material Options:
   Common materials include SUS304, 316L, 321, etc., allowing for selection based on specific usage environments.

5. Strong Corrosion Resistance:
   Thanks to the properties of stainless steel, these tubes can resist corrosion from acids, alkalis, and salts.

6. Great Machinability:
   Precision tubes are easy to process further, such as bending, flaring, reducing, and welding.

Applications of Stainless Steel Precision Tubes:

1. Automotive Manufacturing:
   Used for fuel pipes, brake pipes, and exhaust systems.

2. Medical Equipment:
   Used to manufacture high-precision components such as medical needles and catheters.

3. Aerospace:
   Applied in hydraulic systems and fuel delivery systems for aircraft and spacecraft.

4. Industrial Manufacturing:
   Used for precision mechanical parts, bearings, and cylinders.

5. Food Industry:
   Utilized in pipelines of food processing machinery.

6. Instruments and Meters:
   Used in transmission systems of high-precision measuring instruments.

Manufacturing Process:

• Cold Drawing (Cold Rolling):
  Precision molds and cold processing achieve strict size and surface quality standards.
• Heat Treatment:
  Enhances toughness and stability while improving structural properties.
• Surface Treatment:
  Processes like pickling and polishing ensure bright and clean tube surfaces.

Common Specifications:

The outer diameter typically ranges from 0.2mm to 76mm, with wall thickness from 0.05mm to 2mm. Custom sizes can be manufactured according to specific requirements.

How to Choose Stainless Steel Precision Tubes:

1. Define the Application: Select materials and dimensions based on usage scenarios.
2. Focus on Precision Requirements: Different industries have varying tolerance demands.
3. Choose Reliable Manufacturers: High-quality raw materials and precise processing are key to ensuring superior product quality.
