Manufacturing Process

  1. Material Selection: Low-carbon steel billets for superior weldability and structural integrity.
  2. Pipe Formation: Electric Resistance Welding (ERW) ensures seamless joints for heavy-duty applications.
  3. Hot-Dip Galvanizing: Immersion in molten zinc (450°C) creates a uniform protective layer, enhancing corrosion resistance.
  4. Precision Machining: Threaded, grooved, or flanged ends for compatibility with coupling galvanized pipe systems.
  5. Quality Assurance: Hydrostatic testing, zinc thickness verification, and ultrasonic flaw detection.

Key Features & Benefits

1. Superior Structural Integrity

  • Tensile Strength: Withstands up to 500 MPa, ideal for high-pressure industrial pipelines and structural frameworks.
  • Bending Performance: Heavy-wall design allows bending galvanized steel pipe up to 2x diameter without compromising integrity.
  • Corrosion Resistance: Zinc coating prevents rust in humid, saline, or chemical-exposed environments.

2. Modular Compatibility

  • Connecting PEX to Galvanized Pipe: Use threaded adapters or compression fittings for secure transitions between materials.
  • Coupling Solutions: Flanged or grooved connectors enable rapid assembly in tight spaces.

3. Cost-Effective Longevity

  • Cost of Replacing Galvanized Pipes: Our connectors extend system lifespan (25+ years), reducing long-term replacement costs.
  • Low Maintenance: No frequent recoating required, unlike ungalvanized alternatives.

Technical Insights

Tensile & Bending Strength

Heavy-wall galvanized pipes retain 95% of their original strength post-galvanizing, ensuring reliability under extreme stress. The bending tolerance is validated through mandrel tests, confirming no kinking or wall thinning.

 

Weight Calculation Formula

Weight (lbs) = (Outer Diameter - Wall Thickness) × Wall Thickness × 10.68 × Length (ft)
Example: A 3" (OD 88.9mm) pipe with 6mm WT and 10ft length weighs ~28.5 lbs.

Why Stainless Steel Can Rust

While stainless steel resists corrosion, improper handling or environmental factors may cause rust:

  • Chloride Exposure: Saltwater or industrial chemicals degrade the chromium oxide layer.
  • Mechanical Damage: Scratches or abrasions expose iron to oxidation.
  • Low Oxygen Environments: Inhibits self-healing of the protective oxide layer.

FAQs

Q: Can I use SharkBite fittings for connecting PEX to galvanized pipe?
A: While SharkBite fittings work with copper/PEX, galvanized pipes’ rough surfaces may compromise seals. Use threaded brass adapters for leak-proof transitions.

 

Q: What factors affect the cost of replacing galvanized pipes?
A: Labor (8-10/ft for galvanized), and accessibility. Heavy-wall connectors reduce replacement frequency.
