Tubo capilar de acero inoxidable
Stainless Steel Capillary Tubes are high-precision, corrosion-resistant tubes essential for applications requiring accurate flow control and durability.
Their production involves cold drawing, recocido, acabado superficial, and careful inspection to meet stringent dimensional and performance standards.
- Descripción
Stainless Steel Capillary Tubes are thin-walled, small-diameter tubes used in applications requiring precise fluid control, alta resistencia a la corrosión, y durabilidad.
Son ampliamente utilizados en refrigeration systems, climatización, dispositivos médicos, instrumentation, hydraulic systems, and laboratory equipment.
Capillary tubes require high precision in diameter, espesor de pared, y acabado superficial, which demands specialized manufacturing and processing techniques.
Proceso de fabricación
1. Selección de materiales
-
High-quality stainless steel, típicamente 304, 304l, o 316, is selected for corrosion resistance, ductilidad, 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. Recocido
-
Solution annealing is performed to relieve internal stresses caused by cold drawing.
-
Enhances ductilidad, resistencia a la corrosión, and mechanical stability.
4. Tratamiento superficial
-
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 longitudes estándar o personalizadas, depending on application requirements.
6. Inspection
-
Dimensional checks for diámetro exterior, espesor de pared, and roundness.
-
Surface quality inspection ensures smooth finish for fluid flow and precision applications.
