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.
