Technical Properties

Tensile & Bend Strength

  • Tensile Strength: Ranges from 350–550 MPa (ISO 1461), exceeding ASTM A53 Grade B requirements for industrial pipelines. This ensures reliability in high-stress applications like structural frameworks and water distribution systems.
  • Bend Strength: Achieves 3T bend radius (3x pipe diameter) without cracking, validated through cold-forming tests. Ideal for outdoor projects requiring flexibility, such as agricultural irrigation systems.

Weight Calculation

Weight (kg/m) = (OD – WT) × WT × 0.02466
Example: For a 4" OD pipe with 6mm wall thickness:
(114.3 – 6) × 6 × 0.02466 = 16.2 kg/m. Custom calculators provided for bulk orders.

 

Identification Marking

  • Laser-etched labels include:
    • Grade (e.g., S275JR, ASTM A106).
    • Zinc coating thickness (e.g., Z275).
    • ISO 9001 certification and production batch code.

Why Stainless Steel Corrodes?

While galvanized pipe resists rust via sacrificial zinc protection, stainless steel may corrode due to:

  1. Chloride Exposure: Coastal environments or de-icing salts induce pitting, especially in 304/316 grades.
  2. Mechanical Damage: Scratches or improper welding expose the base metal to oxidation.
  3. Galvanic Corrosion: Contact with dissimilar metals (e.g., copper) accelerates degradation.
  4. High-Temperature Stress: Prolonged exposure to >400°C destabilizes passive oxide layers.

Manufacturing Process

Stage Description
Material Prep Low-carbon steel (Q235B) pickled to remove oxides, ensuring optimal zinc adhesion.
Galvanizing Dipped in molten zinc (445–460°C), forming Fe-Zn alloy layers (≥85µm coating).
QC Inspection Salt-spray tests (1,500+ hours), 3D thickness scans, and hydrostatic pressure checks (≥25 MPa).

Durability & Maintenance

  • How long can galvanized pipe last: Properly maintained galvanized pipes can endure 50+ years in moderate environments. Coastal or high-humidity regions may reduce lifespan to 20–30 years.
  • For repairs, use a pipe cutter for galvanized pipe like the VEVOR 3PCS Tubing Cutter Set or RIDGID Model 258 to ensure clean, burr-free cuts.
