Product Specifications

Premium-grade galvanized pipes tailored for industrial durability and precision

Mechanical Properties

Tensile Strength

Our galvanized steel gas pipe achieves tensile strengths ranging from 315 MPa (Q195) to 630 MPa (Q345). These values ensure structural integrity in high-pressure environments, such as gas distribution systems and HVAC frameworks. For instance, Q235-grade pipes (375–500 MPa) are ideal for industrial scaffolding and underground utilities due to their balanced strength-to-weight ratio.

Bending Strength

The bending strength of galvanized pipes is approximately 60% of tensile strength, allowing flexibility for complex installations like handrails, agricultural machinery, and automotive exhaust systems. This property outperforms galvanized pipe vs black pipe alternatives, which lack zinc protection and are prone to rapid corrosion under mechanical stress.

Identification & Standards

Marking Methods

• ASTM A53/A106: Seamless/welded galvanized steel pipes for general and high-temperature service.
• EN 10255: European standards for dimensional tolerances (e.g., ±1% wall thickness) and zinc adhesion testing.
• JIS G3466: Japanese specifications for structural applications, including earthquake-resistant designs.
• Grade Codes: Laser-etched markings (e.g., "Q235" or "S355") ensure traceability and compliance with OEM requirements.

Weight Calculation

Formula

Weight per meter (kg/m) = (Outer Diameter – Wall Thickness) × Wall Thickness × 0.02466
Example: For a galvanized steel gas pipe with 50mm OD and 3mm thickness:
(50 – 3) × 3 × 0.02466 = 3.48 kg/m .

Custom Shapes

• Round Pipes: Use the standard formula.
• Square/Rectangular Pipes: Weight = (4 × Wall Thickness × (Side Length – Wall Thickness)) × 0.00785.

Stainless Steel Corrosion: Causes & Prevention

Why Does Stainless Steel Rust?

1. Surface Contamination: Oil, grease, or iron particles disrupt the passive chromium oxide layer, leading to localized rust.
2. Chloride Exposure: Coastal or industrial environments accelerate pitting corrosion in grades like 304/316L.
3. Mechanical Damage: Scratches or weld splatter expose raw steel to oxidation.
4. Improper Heat Treatment: Incorrect annealing reduces chromium’s corrosion-blocking efficacy.

Key Comparisons & Applications

galvanized pipe vs black pipe

• Corrosion Resistance: Galvanized pipes excel in humid or alkaline environments due to zinc barriers, while black pipes (uncoated carbon steel) require frequent maintenance.
• Cost: Black pipes are 20–30% cheaper initially but incur higher lifecycle costs due to rust replacement.

galvanized pipe vs copper

• Durability: Copper pipes resist acidic water but degrade in alkaline soils, whereas galvanized pipes offer balanced pH resilience.
• Applications: Copper is preferred for potable water (antimicrobial properties), while galvanized suits gas lines and structural frameworks.

• Safety: Zinc coatings prevent methane leaks and static sparks, compliant with NFPA 54/ANSI Z223.1 standards.
• Installation: Threaded or grooved ends simplify joining without specialized welding.
