Galvanized Industrial Pipe

 

Galvanized industrial pipe is corrosion-resistant welded steel pipes widely used in construction, machinery, energy, transportation, and infrastructure. By coating the surface of the steel pipe with a dense zinc layer, its corrosion resistance is significantly improved, extending its service life. As a key material for industrial structures and fluid transportation, galvanized industrial pipes combine strength, durability, and economy.

 

 

 

1. Hot-Dip Galvanized Pipe

Process: The welded steel pipe is first formed, then immersed entirely in molten zinc to form a zinc-iron alloy protective layer.

Zinc layer thickness: 200–460 g/m², strong adhesion, corrosion protection lifespan of 10–20 years.

Features: The weld area is also covered with zinc, providing excellent overall corrosion resistance, suitable for outdoor and humid environments.

 

2. Pre-Galvanized Pipe

Process: Made by rolling and welding pre-galvanized steel strip.

Zinc layer thickness: Thinner, no zinc layer at the weld, limited corrosion resistance.

Features: Smooth surface, low cost, mostly used in dry indoor environments or lightweight structures.

 

> Mainstream recommendation in industrial fields: Hot-dip galvanized pipe, due to its more reliable full-surface protection.

 

 

 Excellent Corrosion Resistance
The zinc coating, through a sacrificial anodic protection mechanism, effectively prevents the substrate from rusting, making it particularly suitable for high-humidity and high-salt environments such as coastal areas, chemical plants, and underground locations.

 

 High-Strength Structure
Industrial galvanised pipes are made of Q195, Q235B, or Q355B materials, with a tensile strength ≥370MPa, capable of withstanding high loads and impacts.

 

 Easy Installation

Supports threaded connections, flange connections, or welding, adaptable to various engineering scenarios.

 

 Economical and Practical

Compared to stainless steel pipes, industrial galvanized pipes are less expensive; compared to ordinary black pipes, they have a longer service life.

 Outdoor or highly corrosive environments → Select hot-dip galvanized pipes with a zinc coating ≥275g/m²;

 

 Welded areas → It is recommended to apply cold-dip galvanizing coating for corrosion protection and reinforcement;

 

 Storage and transportation → Avoid prolonged contact with acids, alkalis, and salts. Elevate the pipes during stacking to prevent moisture and the formation of "white rust."
