Key Features
- Superior Corrosion Resistance: The hot-dip galvanized layer forms a protective zinc-iron alloy, preventing rust even in humid or saline environments.
- High Strength-to-Weight Ratio: Ideal for structural applications requiring durability without excessive weight.
- Precision Manufacturing: Tolerances within ±1% ensure seamless integration into complex projects.
- Versatility: Suitable for water supply, gas pipelines, scaffolding, and HVAC systems.
Technical Explanations
Tensile & Bend Strength
Our pipes achieve tensile strength of 370–550 MPa, ensuring resistance to cracking under heavy loads. The bend strength is optimized through cold-forming processes, allowing the pipe to withstand deformation without structural failure. For Sch 40 galvanized pipe, wall thickness ensures exceptional pressure resistance (up to 300 PSI).
Weight Calculation
Use the formula:
Example: A 3 inch galvanized steel pipe (OD: 88.9 mm, WT: 5.49 mm) weighs approximately 11.29 kg/m.
Identification Marking
Pipes are stamped with:
- ASTM standard (e.g., ASTM A53)
- Size (e.g., 1 inch galvanized steel pipe)
- Manufacturer’s logo
- Coating type (hot-dip or electro-galvanized).
Why Stainless Steel Can Rust
While stainless steel resists corrosion, improper handling or environmental factors may cause rust:
- Electrochemical Corrosion: Contact with dissimilar metals in humid conditions creates galvanic cells.
- Chemical Exposure: Acids, chlorides, or industrial pollutants degrade the passive oxide layer.
- Mechanical Damage: Scratches or abrasions expose the underlying steel to oxidation.
- Low-Quality Alloys: Substandard chromium/nickel content reduces corrosion resistance.
Galvanizing Process
- Surface Preparation: Acid pickling removes impurities and oxides.
- Fluxing: Immersion in zinc ammonium chloride to enhance coating adhesion.
- Hot-Dip Galvanizing: Dipping in molten zinc (450°C) to form a metallurgical bond.
- Cooling & Inspection: Air-cooling followed by quality checks for coating uniformity.
Applications
- Construction: Structural frameworks, handrails, and roofing.
- Plumbing: Water distribution systems and sewage lines.
- Agriculture: Irrigation systems and greenhouse structures.
- Mining: Ventilation and slurry transport pipelines.
