Product Description

GH3030 Capillary Tubes: Precision Engineering for High-Temperature Applications

GH3030 capillary tubes are engineered for precision fluid control in high-temperature operations. With 58% nickel and 20% chromium, the alloy offers exceptional oxidation resistance up to 1100°C and maintains strength during thermal cycling.

Manufacturing Excellence:

• Vacuum Induction Melting: Ensures ultra-low impurity content.
• Cold Drawing & Annealing: Multi-stage process for optimal mechanical properties.
• Electropolishing: Achieves a surface finish of Ra ≤0.1μm.
• Eddy Current Testing: 100% inspection for defect detection.

Applications:

• Aerospace: Fuel injectors in scramjet engines.
• Energy: Coolant channels in fusion reactors.
• Industrial: Gas quenching nozzles.
• Research: High-temperature sensor lines.
• Electronics: MOCVD reactor capillaries.
