Base Material | Material | AISI 304 Stainless Steel (UNS S30400) Capillary Tubing |
Key Properties | Good corrosion resistance (suitable for water/steam), high strength, non-toxic, easily sterilizable. | |
Component Design | Function | Directs and shapes a fluid stream into a defined spray pattern (jet, fan, cone, mist). |
Typical Features | Machined orifices/slotsat tip or along side,angled tip(e.g., 15°, 30°, 90°),mounting threads/flanges,bent/formed sections. | |
Orifice Types | Round hole, rectangular slot, conical bore, or custom shape milled into the tube wall. | |
Dimensions | Tube Outer Diameter (OD) | Custom, typically1.0 mm to 6.0 mm. |
Tube Inner Diameter (ID) | Custom, based on OD and required flow rate. | |
Wall Thickness | 0.2 mm to 1.0 mm(must sustain internal pressure and machining). | |
Overall Length | Custom, typically20 mm to 200 mm. | |
Orifice Size | Width/Diameter: 0.1 mm to 1.0 mm(machining limited). | |
Manufacturing & Precision | Core Process | Precision CNC Micro-Millingand Drilling. Tube may be fixtured in a 5-axis mill for complex angles. |
Orifice Tolerance | Position: ±0.05 mm. Size: ±0.02 mm(depending on size). | |
Angle Accuracy | Spray angle relative to tube axis:±1°. | |
Internal Finishing | Deburring and smoothing of internal passages post-machining to ensure clean flow. | |
Surface & Finish | Surface Finish | External surfaces can be machined, polished, or sandblasted. |
Internal Cleanliness | Cleaned to remove all machining debris and oils. Electropolishing available for superior cleanability. | |
Performance & Testing | Flow & Spray Pattern | Can be tested and validated per customer specifications for flow rate, pressure drop, and spray distribution. |
Pressure Rating | Dependent on wall thickness and orifice design. Can be calculated and tested for burst pressure. | |
Connection | Ends can be machined with threads (e.g., M3, M4), barbs, or left plain for press-fit/soldering. | |
Quality & Compliance | Inspection | 100% visual inspection. Dimensional verification of critical features via optical measurement or CMM. |
Cleanliness | Packaged clean and dry. Can be cleaned and bagged per industrial or medical cleanliness standards. | |
Applicable Standards | Suitable for use in systems designed per relevant industrial (e.g., SEMI, ISO) or sanitary (e.g., 3-A) standards. |
