Galvanized Pipe Experts | Trusted Steel Pipe Manufacturers

Product Overview

As industry-leading galvanized pipe specialists, we deliver premium-grade steel pipes engineered for durability and versatility. Our products are manufactured using advanced hot-dip galvanization (HDG) technology, ensuring exceptional corrosion resistance for galvanized electrical pipe systems, structural frameworks, and industrial plumbing. Certified to ASTM A53, EN 10255, and UL 6 standards, our pipes are trusted by contractors and DIY enthusiasts alike, with availability at major retailers like galvanized pipe at Lowes and galvanized pipe Home Depot.

Key Properties

  1. Corrosion Resistance
    The zinc coating forms a sacrificial barrier against rust, even in saline or acidic environments. For galvanized electrical pipe installations, inner epoxy linings (≥250μm) prevent sulfide-induced degradation.

     

  2. Mechanical Strength

    • Tensile Strength: ≥500 MPa (ISO 6892-1)
    • Yield Strength: ≥300 MPa
    • Bend Resistance: Withstands 90° bends without cracking (EN 10242).
    • Impact Toughness: 27 J at -20°C (ASTM A370).

  3. Versatility
    Ideal for structural frameworks, HVAC ducts, fire sprinklers, and galvanized pipe at Lowes/Home Depot retail applications.

     

Weight Calculation

Calculate pipe weight using:

Where:

  •  = Outer Diameter (mm)
  •  = Wall Thickness (mm)
  •  = Length (m)
    Example: A 2" Schedule 40 galvanized electrical pipe (OD=60.3mm, WT=3.9mm, 6m length) weighs ≈16.2 kg.

Marking & Identification

Pipes are laser-etched with:

  • Manufacturer’s logo and batch number
  • ASTM/EN standard (e.g., ASTM A53)
  • Dimensions (OD, WT, length).

Why Stainless Steel Rusts?

While stainless steel resists corrosion, rust can occur due to:

  1. Damaged Passive Layer: Scratches or abrasive cleaning disrupt the chromium oxide film.
  2. Chloride Exposure: Coastal or de-icing agents cause pitting corrosion.
  3. Galvanic Corrosion: Contact with carbon steel or copper triggers electrochemical degradation.
  4. High-Temperature Oxidation: Prolonged exposure above 400°C weakens the alloy.

Applications

  • Electrical Systems: Galvanized electrical pipe for UL 6-certified conduit installations.
  • Retail Availability: Widely stocked at galvanized pipe Home Depot and galvanized pipe at Lowes for DIY projects.
  • Industrial Plumbing: Corrosion-free water and gas distribution with NSF 61 compliance.

Certifications & Compliance

  • ISO 9001/14001 (Quality & Environmental Management)
  • UL 6 / FM Approved (Fire Safety)
  • API 5L/5CT (Oil & Gas Pipelines)
