Stainless Steel Capillary Tubes are high-precision, corrosion-resistant tubes essential for applications requiring accurate flow control and durability.
Their production involves cold drawing, الصلب, التشطيب السطحي, and careful inspection to meet stringent dimensional and performance standards.

وصف

Stainless Steel Capillary Tubes are thin-walled, small-diameter tubes used in applications requiring precise fluid control, مقاومة عالية للتآكل, والمتانة.
وهي تستخدم على نطاق واسع في refrigeration systems, التدفئة والتهوية وتكييف الهواء, الأجهزة الطبية, instrumentation, hydraulic systems, and laboratory equipment.

Capillary tubes require high precision in diameter, سمك الجدار, والانتهاء من السطح, which demands specialized manufacturing and processing techniques.

عملية التصنيع

1. اختيار المواد

High-quality stainless steel, عادة 304, 304ل, أو 316, is selected for corrosion resistance, ليونة, 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. الصلب

Solution annealing is performed to relieve internal stresses caused by cold drawing.
Enhances ليونة, مقاومة التآكل, والاستقرار الميكانيكي.

4. المعالجة السطحية

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 القطر الخارجي, سمك الجدار, and roundness.
Surface quality inspection ensures smooth finish for fluid flow and precision applications.
