Galvanized Pipe
1.Product Overview
Galvanized steel pipes are carbon steel pipes coated with a protective layer of zinc to prevent rust and corrosion. They are widely used in construction, plumbing, fencing, and industrial applications due to their durability and cost-effectiveness.
Key Features:
Corrosion Resistance: Zinc coating protects against rust and extends service life.
High Strength: Suitable for structural and pressurized applications.
Easy Installation: Compatible with threading, welding, and mechanical joints.
Cost-Effective: Lower maintenance costs compared to non-coated pipes.
2. Types of Galvanized Pipes
(1) Hot-Dip Galvanized (HDG) Pipes
Process: Submerged in molten zinc (450°C) for a thick, durable coating (≥85µm).
Standards: ASTM A53, BS 1387, EN 10240
Applications: Water supply, gas distribution, outdoor structures.
(2) Electro-Galvanized (EG) Pipes
Process: Electroplated with a thinner zinc layer (5–25µm).
Standards: ASTM A153, ISO 2081
Applications: Indoor plumbing, electrical conduits, lightweight frameworks.
