Product Key Highlights: Superior anti corrosion performance, tight zinc alloy coating, good mechanical property, easy welding & cutting, rich size selection, long service life, suitable for outdoor & underground projects
Product Overview
Hot-dip Galvanized Steel Pipe is high performance steel tubular material processed by hot-dip galvanizing technology, based on welded or seamless steel pipe substrates. Through metallurgical reaction between steel base and molten zinc liquid, a compact zin iron alloy protective layer is formed on steel surface. Featuring outstanding rust proof & anti corrosion performance, firm coating adhesion and convenient on site fabrication, it is an ideal tubular product for water supply drainage, fire fighting, structural framework and various overseas engineering projects.
Key Features
Excellent Anti Corrosion Performance Zinc alloy coating isolates moisture and air, performs well in humid, coastal and underground buried working conditions, greatly extending service life.
Firm Coating Adhesion Zinc layer keeps intact during cutting, bending and transportation without peeling or chipping off.
Rich Customized Dimensions Wide range of outer diameter, wall thickness and arbitrary cut to length to satisfy diversified project requirements.
Good On Site Processability Suitable for common cutting, welding and drilling operations for field installation.
Stable Mechanical Performance Retain original mechanical strength of steel substrate, meet load bearing requirements for piping and structural applications.
Long Service Life Effective rust protection reduces later maintenance frequency for outdoor and buried usage.
Mechanical Properties
Stable comprehensive mechanical performance of steel substrate Good cutting, welding and bending capability High zinc coating adhesion against peeling and cracking Adaptable for secondary on site fabrication Consistent quality for mass volume production
Production Process
Raw steel pipe inspection → Pickling & degreasing pretreatment → Hot-dipping in molten zinc bath → Cooling & passivation treatment → Zinc layer thickness testing → Surface inspection → Finished HDG steel pipe
This process ensures: Uniform zinc coating thickness; Stable surface finish; Reliable anti corrosion performance; Superior on site processability
Applications
