Detailed introduction
Product Overview
Galvanized steel pipes are steel pipes that have been coated with a protective layer of zinc to prevent rust and corrosion. This process significantly extends the lifespan of the pipes, making them ideal for various industrial and construction applications.
Types of Galvanized Steel Pipes
Hot-Dip Galvanized Pipes: Superior corrosion resistance with a thick, durable zinc coating
Cold Galvanized Pipes: Electroplated zinc coating suitable for specific applications
Hot-Dip Galvanized Pipes
Hot-dip galvanized pipes are manufactured by immersing steel pipes in molten zinc, creating a metallurgical bond between the zinc and steel. This process forms multiple protective layers that offer exceptional durability.
Key Features
Zinc-iron alloy layer provides superior corrosion resistance
Coating thickness typically ranges from 45μm to 200μm
Service life of 20-50 years depending on environment
Suitable for outdoor applications and harsh conditions
Manufacturing Process
Alkaline cleaning to remove grease and dirt
Acid pickling to eliminate surface oxides
Fluxing to prepare surface for galvanizing
Hot-dip galvanizing in molten zinc at 450°C
Cooling and passivation treatment
Cold Galvanized Pipes
Cold galvanized pipes are produced through electroplating, where a thin layer of zinc is deposited on the steel surface through electrical current. While less durable than hot-dip galvanizing, it offers precise coating control.
Characteristics
Zinc coating weight: 10-50g/m²
Smoother surface finish compared to hot-dip
Primarily used for indoor applications
Not recommended for water supply systems
