Lightweight Galvanized Pipe | Easy-Install Iron Tube Solutions

Product Overview

Our lightweight galvanized pipe offers unmatched durability and corrosion resistance, designed for contractors and DIY enthusiasts seeking hassle-free installation and long-term reliability. With advanced hot-dip galvanizing technology, these pipes are ideal for plumbing, HVAC, and structural applications. Compatible with compression coupling for galvanized pipe, our solutions simplify repairs and upgrades in both residential and industrial settings.

Specifications & Technical Data

Key Features

1. Lightweight Design: 30% lighter than traditional steel pipes, reducing transport and labor costs.
2. Corrosion Resistance: Hot-dip galvanized coating prevents rust, even in humid or coastal environments.
3. Easy Installation: Compatible with compression coupling for galvanized pipe for leak-proof joints.
4. Cost-Effective: Lower cost to replace galvanized pipes compared to full-system overhauls.

Technical Explanations

Tensile & Bend Strength

Our pipes achieve tensile strength of 370–550 MPa, ensuring structural integrity under high-pressure conditions. The bend strength is optimized through cold-rolling processes, allowing the pipe to withstand deformation without cracking. For example, a 2-inch pipe can endure lateral forces up to 1,200 N/m, making it suitable for seismic zones.

Weight Calculation

Use the formula:
Weight (kg/m)=1000(OD−WT)×WT×0.02466
Example: A 1-inch pipe (OD: 33.7 mm, WT: 3.38 mm) weighs approximately 2.5 kg/m.

Identification Marking

Pipes are stamped with:

• ASTM/EN standard (e.g., ASTM A53)
• Size (e.g., 1/2" or DN15)
• Zinc coating grade (Z30-Z275).

Why Stainless Steel Can Rust

While stainless steel is corrosion-resistant, certain conditions may cause rust:

1. Galvanic Corrosion: Contact with dissimilar metals (e.g., copper) in humid environments triggers electrochemical reactions.
2. Chemical Exposure: Chlorides (e.g., road salt) or acids degrade the passive chromium oxide layer.
3. Mechanical Damage: Scratches or abrasions expose untreated steel to oxidation.
4. Low-Quality Alloys: Substandard grades (e.g., 201 vs. 304) reduce corrosion resistance.

Galvanizing Process

1. Surface Cleaning: Acid pickling removes mill scale and impurities.
2. Fluxing: Zinc ammonium chloride immersion enhances adhesion.
3. Hot-Dip Galvanizing: Dipping in molten zinc (450°C) forms a metallurgical bond.
4. Cooling & Inspection: Air-cooling followed by thickness checks (40–275 g/m²).

Applications

• Plumbing: Repair corroded galvanized pipe with compression couplings for seamless upgrades.
• HVAC: Lightweight design reduces load on support structures.
• Agriculture: Resists soil acidity and moisture in irrigation systems.
• Industrial: Ideal for chemical transport due to zinc’s inert properties.
