Weatherproof Galvanized Pipe Fittings | Outdoor Project Durability

Product Specifications

Parameter Details
Zinc Coating 275g/m² (Z275) hot-dip galvanized, compliant with ASTM A153 and EN ISO 1461
Diameter Range 1/2" to 6" (15mm–150mm) – galvanized threaded pipe options available for seamless connections
Wall Thickness 2.0mm–12.7mm, ideal for structural supports, handrails, and outdoor HVAC systems
Standards ASTM A53, EN 10255, BS 1387, ISO 9001 certified
Surface Finish Zero spangle, chromated (Cr3+), oil-free for corrosion resistance in coastal climates
Hardness 150–250 HB (Brinell hardness), ensuring durability under mechanical stress
Thread Type NPT (National Pipe Thread), BSPT (British Standard Pipe Taper) for global compatibility
Temperature Range -30°C to 120°C, suitable for extreme weather conditions

Technical Properties

Tensile & Bend Strength

  • Tensile Strength: Ranges from 350–500 MPa (EN 1562 standards), capable of withstanding heavy loads in construction and infrastructure projects.
  • Bend Strength: Achieves 4T bend radius (4x pipe diameter) without cracking, validated through cold-forming tests for outdoor applications like agricultural frameworks.

Weight Calculation

Weight (kg/m) = (OD – WT) × WT × 0.02466
Example: For a 2" OD pipe with 3mm wall thickness:
(50 – 3) × 3 × 0.02466 = 3.48 kg/m. Custom calculators provided for bulk galvanized threaded pipe orders.

Identification Marking

  • Laser-etched labels include:
    • Grade (e.g., EN-GJMB-350-10).
    • Zinc coating thickness (Z275).
    • Production batch and compliance marks (e.g., UL Listed, FM Approved).

Why Stainless Steel Corrodes?

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

  1. Chloride Exposure: Coastal environments or de-icing salts induce pitting.
  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.

Manufacturing Process

Stage Description
Material Prep Low-carbon steel (Q235) pickled to remove oxides, ensuring optimal zinc adhesion.
Galvanizing Dipped in molten zinc at 450°C, forming Fe-Zn alloy layers (≥70µm coating).
Threading CNC-machined threads (NPT/BSPT) for leak-proof galvanized threaded pipe connections.
QC Inspection Air-tightness tests (0.6MPa pressure), salt-spray tests (1,000+ hours), and 3D thickness scans.

Maintenance & Repair

  • How to Repair Galvanized Pipe:
    1. For minor leaks, use epoxy putty or compression couplings.
    2. Replace severely corroded sections using a pipe cutter for galvanized pipe to ensure clean cuts.
    3. Seal threads with PTFE tape or thread sealant to prevent future leaks.
  • Recommended tools: Pipe cutter for galvanized pipe (e.g., VEVOR 3PCS Tubing Cutter Set) ensures burr-free cuts.
