Versatile Galvanized Pipe | Multi-Purpose Water & Gas Lines

Parameter	Details
Material	Low-carbon steel (Q195, Q235) with hot-dip galvanized coating (60–275 g/m² zinc)
Standards	ASTM A53, BS1387, EN10219, API 5L, ISO 9001
Diameter Range	1/2" (21.3 mm) to 12" (323.9 mm), including black galvanized pipe for industrial use
Wall Thickness	0.5–6.0 mm (customizable for high-pressure applications)
Length	Standard: 6 m, 12 m; Custom: 1–12 m (pre-cut galvanized 3 x2 sections of vent pipe for sale)
Surface Finish	Smooth spangled finish (hot-dip galvanized), matte or glossy options
Hardness	Rockwell B scale: G300–G550 (suitable for structural loads)
Max. Working Pressure	300 psi (2.07 MPa)

Corrosion Resistance:
- The zinc-iron alloy layer formed during hot-dip galvanizing offers 4–6× longer lifespan than electro-galvanized pipes. Ideal for coastal and high-humidity environments.
- Black galvanized pipe variants provide enhanced UV resistance for outdoor installations.
Durability:
- Tensile Strength: 330–550 MPa (varies by steel grade; Grade Q345 recommended for heavy-duty use).
- Bend Strength: Withstands 180° bending without cracking (tested per ASTM A370).
Versatility:
- Compatible with compression fitting for galvanized pipe, ensuring leak-proof connections for water, gas, and HVAC systems.
- Suitable for structural frameworks, fire sprinklers, and ventilation systems (e.g., galvanized 3 x2 sections of vent pipe for sale).

Stage	Description
Material Prep	Steel coils pickled to remove oxides, followed by fluxing in zinc ammonium chloride.
Pipe Formation	High-frequency induction welding (HFIW) for precision seam integrity.
Galvanizing	Immersion in molten zinc (450–465°C) to form alloy layers.
Quality Control	Hydrostatic testing (1.5× working pressure) and salt spray compliance (5,000+ hours).

Tensile Strength: Ranges from 330 MPa (Grade Q195) to 550 MPa (Grade Q345). Higher grades (e.g., ASTM A106) are ideal for load-bearing structures and high-pressure gas lines.
Bend Strength: Achieves a minimum bend radius of 2.5× pipe diameter without fracture (tested per ISO 8491).

Formula for galvanized pipe weight:
$Weight (kg/m) = \frac{( O D - W T ) \times W T \times 0.02466}{1000}$

Example: A black galvanized pipe with 60.3 mm OD and 3.2 mm WT weighs ~4.5 kg/m.

Pipes are stamped with:
- Manufacturer’s logo
- ASTM standard (e.g., ASTM A53)
- Size (e.g., compression fitting for galvanized pipe compatibility)
- Coating type (HDG for hot-dip)

While stainless steel resists rust due to a chromium oxide layer, corrosion can occur due to:

Chloride Exposure: Coastal environments accelerate pitting (common in vent pipe systems).
Mechanical Damage: Scratches or welding disrupt the oxide layer, exposing the substrate.
Chemical Contamination: Acids or alkalis (e.g., industrial pollutants) degrade protective layers.

Bulk Pricing Advantage: Competitive rates for galvanized 3 x2 sections of vent pipe for sale with volume discounts (FOB: $680–850/ton).
Custom Solutions: Precision threading for compression fitting for galvanized pipe and pre-cut lengths.
Certified Quality: ISO 9001, RoHS, and ASTM compliance with 5,000+ hours of salt spray testing.
Global Logistics: Sea-worthy packaging and 15–30 day delivery worldwide.

While galvanized pipes excel in cost-effectiveness, our stainless steel alternatives offer unmatched longevity for specialized applications:

Superior Corrosion Resistance: Chromium-nickel alloys (e.g., SUS 304/316) resist rust even in acidic or marine environments.
Hygienic & Aesthetic: Non-porous surface prevents bacterial growth, ideal for food processing and architecture.
Low Maintenance: No recoating required, reducing lifecycle costs by 30% compared to galvanized options.
