Kapillarrohr aus Edelstahl
Stainless Steel Capillary Tubes are high-precision, corrosion-resistant tubes essential for applications requiring accurate flow control and durability.
Their production involves Kaltziehen, Glühen, Oberflächenveredelung, and careful inspection to meet stringent dimensional and performance standards.
- Beschreibung
Stainless Steel Capillary Tubes are thin-walled, small-diameter tubes used in applications requiring precise fluid control, hohe Korrosionsbeständigkeit, und Haltbarkeit.
Sie werden häufig verwendet refrigeration systems, HVAC, medizinische Geräte, instrumentation, hydraulic systems, and laboratory equipment.
Capillary tubes require high precision in diameter, Wandstärke, und Oberflächenbeschaffenheit, which demands specialized manufacturing and processing techniques.
Herstellungsprozess
1. Materialauswahl
-
High-quality stainless steel, typischerweise 304, 304L, oder 316, is selected for corrosion resistance, Duktilität, and cleanliness.
2. Tube Extrusion or Drawing
-
Stainless steel billets or tubes are cold-drawn through precision dies to reduce the diameter to capillary size.
-
Multiple passes are used to achieve tight tolerances and uniform wall thickness.
3. Glühen
-
Solution annealing is performed to relieve internal stresses caused by cold drawing.
-
Enhances Duktilität, Korrosionsbeständigkeit, and mechanical stability.
4. Oberflächenbehandlung
-
Internal and external surfaces are polished to reduce roughness, ensuring smooth fluid flow.
-
Pickling and passivation may be applied for enhanced corrosion resistance.
5. Straightening and Cutting
-
Tubes are straightened to prevent kinks or bends.
-
Cut to Standard- oder Sonderlängen, depending on application requirements.
6. Inspektion
-
Maßkontrollen für Außendurchmesser, Wandstärke, and roundness.
-
Surface quality inspection ensures smooth finish for fluid flow and precision applications.
