Stainless Steel Capillary Tubes are high-precision, corrosion-resistant tubes essential for applications requiring accurate flow control and durability.
Their production involves vẽ lạnh, ủ, hoàn thiện bề mặt, and careful inspection to meet stringent dimensional and performance standards.
- Sự miêu tả
Stainless Steel Capillary Tubes are thin-walled, small-diameter tubes used in applications requiring precise fluid control, khả năng chống ăn mòn cao, và độ bền.
Chúng được sử dụng rộng rãi trong refrigeration systems, HVAC, medical devices, instrumentation, hydraulic systems, and laboratory equipment.
Capillary tubes require high precision in diameter, độ dày của tường, và hoàn thiện bề mặt, which demands specialized manufacturing and processing techniques.
Quy trình sản xuất
1. Material Selection
-
High-quality stainless steel, tiêu biểu 304, 304L, hoặc 316, is selected for corrosion resistance, độ dẻo, 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. Ủ
-
Ủ dung dịch is performed to relieve internal stresses caused by cold drawing.
-
Enhances độ dẻo, chống ăn mòn, and mechanical stability.
4. Xử lý bề mặt
-
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 or custom lengths, depending on application requirements.
6. Inspection
-
Dimensional checks for đường kính ngoài, độ dày của tường, and roundness.
-
Surface quality inspection ensures smooth finish for fluid flow and precision applications.
