Seamless-Weld Galvanized Pipe Fittings | Hydraulic System Reliability

Product Specifications

Parameter Details
Zinc Coating 275–350g/m² (Z275–Z350), hot-dip galvanized per ASTM A153/ISO 1461, ensuring corrosion resistance for galvanized steel drain pipe applications
Diameter Range 1/2" to 24" (15–600mm) – galvanized pipe dimensions chart available for precise sizing
Wall Thickness 2.0–25.4mm, ideal for high-pressure hydraulic systems and structural supports
Standards ASTM A53, EN 10255, ISO 9001, BS 1387
Surface Finish Zero spangle, Cr6+-free chromated layer, hot-dip galvanized with ≥85µm coating
Hardness 150–250 HB (Brinell hardness), suitable for mechanical stress in galvanized corrugated metal pipe installations
Thread Compatibility NPT, BSPT, DIN 2999 for global adaptability
Temperature Tolerance -40°C to 400°C, engineered for extreme hydraulic environments

Technical Properties

Tensile & Bend Strength

  • Tensile Strength: Ranges from 350–550 MPa (ISO 1461), exceeding ASTM A53 Grade B requirements for hydraulic and industrial pipelines.
  • Bend Strength: Achieves 3T bend radius (3x pipe diameter) without cracking, validated through cold-forming tests for applications like galvanized corrugated metal pipe frameworks.

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., ASTM A106, S275JR).
    • Zinc coating thickness (e.g., Z275).
    • Compliance marks (ISO 9001, EN 10255).

Why Stainless Steel Corrodes?

While seamless-weld 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, 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).
Seamless Welding High-frequency induction welding ensures joint integrity for galvanized steel drain pipe systems.
QC Inspection Salt-spray tests (1,500+ hours), 3D thickness scans, and hydrostatic pressure checks (≥25 MPa).
