Wall Thickness 2.0–25.4mm, optimized for structural support and high-pressure applications
Standards ASTM A53, EN 10255, ISO 9001, BS 1387, UL 6 for electrical conduits
Surface Finish Spangle-free chromate passivation (Cr3+), hot-dip galvanized with ≥85µm coating
Hardness 150–250 HB (Brinell hardness), validated via Rockwell C tests for mechanical stress resistance
Thread Compatibility NPT, BSPT, DIN 2999 for global adaptability
Temperature Tolerance -40°C to 400°C, engineered for extreme industrial and marine environments

Technical Properties

Tensile & Bend Strength

  • Tensile Strength: Ranges from 350–550 MPa (ISO 1461), exceeding ASTM A53 Grade B requirements. Validated through Charpy V-notch impact tests at -20°C, ensuring reliability in high-pressure applications like compression coupler for galvanized pipe installations.
  • Bend Strength: Achieves 3T bend radius (3x pipe diameter) without cracking, proven in cold-forming tests for structural frameworks and drainage systems.

Weight Calculation

Weight (kg/m) = (OD – WT) × WT × 0.02466
Example: For a 6" OD pipe with 8mm wall thickness:
(168.3 – 8) × 8 × 0.02466 = 31.6 kg/m. Custom calculators provided for bulk orders.

Identification Marking

  • Laser-etched labels include:
    • Grade (e.g., Q235, S275JR).
    • Zinc coating thickness (Z275–Z350).
    • Compliance marks (ISO 9001, ASTM A53).

Why Stainless Steel Corrodes?

While galvanized connectors resist rust via sacrificial zinc protection, stainless steel may corrode due to:

  1. Chloride Exposure: Coastal environments or de-icing salts induce pitting in 304/316 grades, penetrating passive oxide layers.
  2. Mechanical Damage: Scratches from connecting PVC to galvanized pipe tools or improper welding expose base metal to oxidation.
  3. Galvanic Corrosion: Contact with dissimilar metals (e.g., does SharkBite work on galvanized pipe) accelerates degradation in mixed-metal systems.
  4. High-Temperature Stress: Prolonged exposure >400°C destabilizes chromium oxide layers, leading to intergranular corrosion.

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).
Threading CNC-machined threads (NPT/BSPT) for leak-proof connections in compression coupler for galvanized pipe systems.
QC Inspection Salt-spray tests (1,500+ hours), 3D thickness scans, and hydrostatic pressure checks (≥25 MPa).

Applications & Maintenance

  • Hybrid Plumbing: Trusted for connecting PVC to galvanized pipe networks in chemical plants, ensuring compatibility and leak-proof joints.
  • SharkBite Compatibility: Does SharkBite work on galvanized pipe? Yes, but ensure the zinc coating is intact to prevent galvanic corrosion.
  • Corrosion Management: Regular inspections and Teflon tape sealing at threaded joints prevent leaks.

Keywords Integration:

  • Streamline compression coupler for galvanized pipe installations with precision-threaded connectors.
  • Trusted solutions for connecting PVC to galvanized pipe compliant with NSF/EN standards.
  • Resolve compatibility queries like does SharkBite work on galvanized pipe using non-abrasive tools to preserve coating integrity.
