ステンレス鋼毛細管
Stainless Steel Capillary Tubes are high-precision, corrosion-resistant tubes essential for applications requiring accurate flow control and durability.
Their production involves cold drawing, アニーリング, 表面仕上げ, and careful inspection to meet stringent dimensional and performance standards.
- 説明
Stainless Steel Capillary Tubes are thin-walled, small-diameter tubes used in applications requiring precise fluid control, 高い耐食性, そして耐久性.
それらは広く使用されています refrigeration systems, 空調設備, 医療機器, instrumentation, hydraulic systems, and laboratory equipment.
Capillary tubes require high precision in diameter, 壁の厚さ, そして表面仕上げ, which demands specialized manufacturing and processing techniques.
製造工程
1. 材料の選択
-
High-quality stainless steel, 通常 304, 304L, または 316, is selected for corrosion resistance, 延性, 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. アニーリング
-
Solution annealing is performed to relieve internal stresses caused by cold drawing.
-
Enhances 延性, 耐食性, 機械的安定性.
4. 表面処理
-
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 標準またはカスタムの長さ, depending on application requirements.
6. 検査
-
寸法チェック 外径, 壁の厚さ, and roundness.
-
Surface quality inspection ensures smooth finish for fluid flow and precision applications.
