φ8-φ12mm Ultra-thin-walled Galvanized Capillary Tube

Product Overview

φ8-φ12mm Ultra-thin-walled Galvanized Capillary Tube is a precision-engineered tube designed for applications requiring small diameters and thin walls. It falls under Asia Metal's galvanized coil product category.

Specifications

• Outer Diameter: 8mm to 12mm
• Wall Thickness: 0.2mm to 0.5mm (ultra-thin)
• Length: Standard coils up to 100m; custom lengths available
• Material: Low-carbon steel with hot-dip galvanization
• Zinc Coating: 50-100g/m²
• Tolerance: ±0.05mm on diameter

Material and Coating

The tube is made from cold-rolled low-carbon steel strip, formed into capillary shape, and welded longitudinally. Hot-dip galvanization provides corrosion resistance. The process ensures uniform zinc coating adhering to ASTM A653 standards.

Applications

This tube is used in refrigeration systems, medical equipment, instrumentation, and hydraulic lines where space constraints and corrosion protection are needed. It supports fluid transfer in compact assemblies.

Quality Standards

Products comply with ISO 9001 for manufacturing processes. Testing includes visual inspection, dimensional verification, and coating weight measurement. Tubes are supplied in coiled form for easy handling and installation.
