Eco-Friendly Galvanized Pipe: Sustainable Construction Material

Product Specifications

Key Properties

1. Corrosion Resistance: The hot-dip galvanized coating forms a zinc-iron alloy layer, providing exceptional protection against rust and oxidation, even in harsh environments.
2. Durability: With a lifespan of 20–50 years, these pipes withstand extreme temperatures (-40°C to 120°C) and mechanical stress.
3. Eco-Friendly: Fully recyclable and compliant with environmental regulations, reducing carbon footprint.
4. Hygienic: Non-porous surface prevents bacterial growth, ideal for potable water systems.

Manufacturing Process

• Hot-Dip Galvanizing:

  1. Pickling: Acid treatment removes surface impurities and oxides.
  2. Fluxing: Ammonium chloride/zinc chloride solution ensures proper zinc adhesion.
  3. Galvanizing: Immersion in molten zinc (450–460°C) creates a uniform alloy layer.
  4. Cooling & Inspection: Air-cooled and tested for coating thickness and integrity.

• Threading: Precision-cut threads using galvanized pipe threader tools ensure leak-proof connections.

   

Technical Details

Tensile Strength

Tensile strength measures the maximum stress a pipe can endure before breaking. Our galvanized pipes achieve 330–500 MPa, suitable for high-pressure applications like water mains and gas lines.

Bending Strength

The zinc coating enhances flexibility, allowing bending angles up to 180° without cracking. Cold bending is recommended for radii ≥4× pipe diameter.

Weight Calculation

Use the formula:
Weight (kg/m)=1.0599(OD−WT)×WT×0.02466
Example: For a 1" pipe (OD: 33.7 mm, WT: 3.38 mm):
Weight=1.0599(33.7−3.38)×3.38×0.02466≈2.5kg/m

Identification Marking

Each pipe is stamped with:

• Manufacturer’s logo
• ASTM/BS standard
• Size (OD × WT)
• Grade (e.g., Q235)
• Batch number

Why Stainless Steel Can Rust?

While stainless steel is corrosion-resistant, improper use or maintenance can lead to rust:

1. Chloride Exposure: Saltwater or chlorine damages the passive chromium oxide layer.
2. Mechanical Damage: Scratches or abrasions expose the base metal to oxidation.
3. Low Chromium Content: Grades with <10.5% chromium lack adequate corrosion resistance.
4. Galvanic Corrosion: Contact with carbon steel accelerates rusting.
5. High Humidity: Prolonged moisture exposure degrades the protective layer.

Regular cleaning with pH-neutral solutions and avoiding abrasive tools can mitigate these risks.

Applications & Compatibility

• Plumbing: Compatible with galvanized steel pipe Home Depot fittings for DIY projects.
• Construction: Used in structural frameworks, scaffolding, and roofing.
