Specifications & Technical Data

Mechanical Properties

Tensile Strength
Galvanized steel pipes exhibit exceptional tensile strength, ranging from 315–630 MPa, depending on the steel grade. For example:

• Q195: 315–430 MPa
• Q345: 470–630 MPa
  
  This ensures resistance to deformation under heavy loads, making them ideal for structural applications like building frameworks and industrial supports.

Bend Strength
With a yield strength of 195–345 MPa, our pipes maintain structural integrity even under bending stress. The galvanized layer further enhances fatigue resistance, critical for applications involving vibrations (e.g., machinery, HVAC systems) .

Identification & Marking

Pipes are labeled with:

1. Laser Etching/Stamping: Includes grade (e.g., Q235), thickness, and standard (e.g., ASTM A53).
2. Color Coding: Per ISO 3864 standards (e.g., blue for water, yellow for gas) .
3. Certification Marks: Third-party inspection stamps (e.g., SGS, BV) for quality assurance.

Weight Calculation

The weight of galvanized pipes can be calculated using:
$\text{Weight (kg/m)}=(OD-WT)\times WT\times 0.02466$
Where:

• OD: Outer Diameter (mm)
• WT: Wall Thickness (mm)

For example, a 50 mm OD pipe with 2.5 mm wall thickness weighs:
$(50-2.5)\times 2.5\times 0.02466=2.93\text{kg/m}$
Online tools like GI Pipe Weight Calculator simplify this process.

Why Stainless Steel Rusts?

While stainless steel is corrosion-resistant, rust can occur due to:

1. Chloride Exposure: Salt or chemicals damage the chromium oxide layer .
2. Mechanical Damage: Scratches or abrasions expose the base metal.
3. Improper Welding: Incomplete passivation post-welding leaves vulnerable spots.
4. Low-Quality Alloys: Grades like 201/202 lack sufficient nickel, reducing corrosion resistance.

Regular maintenance and selecting high-grade stainless steel (e.g., 304/316) mitigate these risks.

Applications & Advantages Over Alternatives

• Cost Efficiency: Replacing galvanized pipes with PVC might save upfront costs (~$0.40–$3/ft), but galvanized steel offers 2–3x longer lifespan .
• Durability: Welded galvanized pipe joints withstand pressures up to 5 MPa, outperforming PVC in high-temperature environments .
• Ease of Installation: Threading galvanized pipe is straightforward with standard tools, unlike complex PVC solvent welding .
