Manufacturing Process
Our stainless steel precision tubes are manufactured through an advanced cold drawing process, followed by precision annealing and finishing steps:
-
Selection of high-purity stainless steel raw materials
-
Cold drawing or cold rolling to achieve required dimensions
-
Bright annealing in a controlled atmosphere
-
Straightening and length adjustment
-
Surface treatment: pickling, polishing, or passivation
-
100% dimensional and surface inspection
-
Optional eddy current or ultrasonic testing for critical applications
Frequently Asked Questions (FAQ)
Q1: What makes precision tubes different from regular stainless steel tubes?
A1: Precision tubes have tighter dimensional tolerances, better surface finishes, and are often used in applications requiring exact size control and cleanliness.
Q2: Do you offer seamless or welded precision tubes?
A2: Yes, we supply both seamless and welded precision tubes based on customer needs and application requirements.
Q3: Can I request ultra-thin wall precision tubes?
A3: Absolutely. We offer precision tubes with wall thickness as low as 0.05mm, suitable for micro-scale or sensitive fluid applications.
Q4: What quality inspections do you perform?
A4: Our tubes undergo dimensional inspection, surface quality check, and optional NDT methods like eddy current or ultrasonic testing.
Q5: Are these tubes suitable for high-pressure fluid systems?
A5: Yes, especially the seamless precision tubes are suitable for high-pressure, high-purity, and leak-sensitive systems.
