What Are the Uses of Galvanized Steel Pipes? A Comprehensive Guide!

Galvanized steel pipes are steel pipes coated with a layer of zinc, known for their excellent rust resistance, durability, and wide range of applications, making them an ideal choice for industries such as construction, water supply, and gas transmission. Whether you're a builder or a homeowner, galvanized steel pipes can provide an economical and high-performance solution for your needs.

1. Galvanized Steel Pipe Specifications, Materials, and Sizes

Galvanized steel pipes come in a variety of specifications, with common sizes including:

Outer Diameter: 15mm to 200mm (e.g., 20mm, 50mm, 100mm).

Wall Thickness: 1.0mm to 6.0mm (e.g., 2.0mm, 3.0mm).

Length: Typically 6 meters or 12 meters, but customizable to meet specific requirements.

Materials:

Q195/Q235: Ordinary carbon steel, suitable for general construction and water supply pipelines.

Q345B: High-strength low-alloy steel, ideal for high-strength applications.

Stainless Steel Composite Pipe: Suitable for highly corrosive environments.

Weight Calculation Formula:

Weight of galvanized steel pipe (kg/m) = 0.02466 × wall thickness (mm) × (outer diameter - wall thickness)

Example: Weight of a 50mm outer diameter, 3.0mm wall thickness galvanized steel pipe = 0.02466 × 3.0 × (50 - 3.0) = 3.48 kg/m.

2. Galvanized Steel Pipe Production Process and Workflow

Hot-Dip Galvanizing Process

Steel pipes are immersed in molten zinc to form a uniform zinc layer.

Hot-dip galvanized steel pipes have a thicker zinc layer, providing excellent rust resistance.

Electro-Galvanizing Process

A zinc layer is applied to the steel pipe surface through electrolysis.

Electro-galvanized steel pipes have a smooth surface, suitable for high-precision processing.

Surface Treatment

Passivation: Enhances the corrosion resistance of the zinc layer.

Oiling: Prevents rust during transportation and storage.

Color Coating: Improves aesthetics, ideal for decorative purposes.

3. Galvanized Steel Pipe Product Features
