Product Details of Hot-dipped Steel Pipe
Description
Hot-dip galvanized steel pipe is manufactured using high-quality carbon steel pipes as the base material. Through an advanced hot-dip galvanizing process, a dense and uniform zinc-iron alloy layer is formed on the surface of the pipe. This zinc coating provides durable electrochemical protection, effectively preventing pipe corrosion, while presenting a characteristic crystalline zinc-flake texture on the surface. The product offers excellent corrosion resistance, high mechanical strength, and a long service life, making it widely applicable in building structures, water transmission pipelines, municipal engineering, agricultural greenhouses, power supports, industrial equipment, and other fields. Based on different galvanizing processes, it is mainly categorized into hot-dip galvanized steel pipes and electro-galvanized steel pipes.
Electro-galvanized steel pipes form a fine zinc layer on the pipe surface through an electrolytic process, with a typical zinc coating thickness of 5–25 μm, resulting in a smooth and uniform surface. This process is suitable for applications requiring high dimensional accuracy and subsequent processing. It is primarily used for indoor electrical conduit pipes, furniture structural pipes, precision instrument components, and decorative purposes.
Hot-dip galvanized steel pipes are produced using a molten zinc immersion process, typically forming a zinc coating thickness of 65–300 μm, which creates a strong metallurgical bond. This process provides comprehensive protection for both the inner and outer walls of the pipe, making it particularly suitable for outdoor exposed environments and fluid transmission applications. Common specifications range from DN15 to DN600, with wall thicknesses of 1.0–20 mm, while custom non-standard sizes are also supported. Hot-dip galvanized steel pipes combine superior corrosion resistance with good workability, making them widely used in construction scaffolding, water supply systems, HVAC pipelines, and structural supports.
Product Features:
- Exceptional Corrosion Resistance: The zinc coating forms a sacrificial anode protection with the steel pipe, maintaining rust prevention even if the surface is scratched. Outdoor service life can reach 20–30 years.
- High Strength and Durability: While retaining the mechanical properties of the base pipe, the zinc coating enhances overall rigidity, providing excellent compression and bending resistance.
- Process Flexibility: Supports various secondary processing methods such as post-galvanizing welding, threading, and stamping.
- Easy Installation: Offers multiple connection interfaces, including standard threaded connections, flange connections, and grooved connections.
