Technical Parameters and Performance Highlights
| Dimension | Key Parameters | Technical Analysis |
|---|---|---|
| Material System | Stainless steel 304/316 (primary choice), carbon steel (zinc-plated) | - 304/316: Resistant to acids, alkalis, and salt spray (salt spray test ≥100 hours), suitable for food, chemical, and marine applications. - Zinc-plated carbon steel: Cost-effective, ideal for dry environments (salt spray test ≥48 hours). |
| Thread Specifications | Pipe threads (G1/8"–G2", NPT1/4"–NPT1"), metric threads (M8–M36) | - Pipe threads: G is a parallel pipe thread (requires a sealant); NPT is a tapered pipe thread (self-sealing, suitable for high pressure). - Metric threads: Designed for mechanical structural connections, with a thread tolerance class of 6g. |
| Custom Dimensions | Length: L=10–100mm (standard: 15/20/25mm); outer diameter: D matches the thread (e.g., G1/2" outer diameter ≈20.95mm); inner diameter: d=D–2*wall thickness (wall thickness: 2–5mm) | The hollow inner diameter can be customized (e.g., larger diameters for cable threading), and the wall thickness ensures tensile strength (≥200MPa). |
| Surface Treatment | Stainless steel mirror polishing (Ra≤1.6μm), blue-white zinc/plated color zinc for carbon steel | Enhances corrosion resistance and aesthetics. Stainless steel can be customized with passivation, nickel plating, or other special treatments. |
