Details about DN150 galvanized steel pipes

DN150 galvanized steel pipe refers to a steel pipe with a nominal diameter of 150 mm, coated with a protective layer of zinc to enhance its corrosion resistance. This type of pipe is widely used in construction, engineering, petrochemical, and other industries due to its durability and strength. The zinc coating acts as a barrier against oxidation and environmental elements, significantly extending the pipe’s service life.

Production Process of DN150 Galvanized Steel Pipe

The manufacturing of galvanized steel pipes generally follows these steps:

Steel Pipe Pretreatment

The raw steel pipe undergoes cleaning processes such as pickling and rust removal to eliminate surface oxides and impurities.

Pickling

This step dissolves iron oxide scale, ensuring a smoother surface for better zinc adhesion.

Galvanizing

The cleaned steel pipe is immersed in a hot-dip zinc bath, where the zinc coating forms through a reaction between the steel and molten zinc.

Cooling

The galvanized pipe is removed from the zinc bath and cooled to solidify the coating, ensuring a uniform and durable protective layer.

Inspection

A thorough quality check is conducted to examine the coating uniformity, adhesion, and physical properties, ensuring compliance with industry standards.

Advantages of DN150 Galvanized Steel Pipe

Superior Corrosion Resistance

The zinc coating provides excellent protection against rust and environmental factors, extending the pipe’s lifespan.

High Strength and Durability

With a robust steel core, galvanized pipes can withstand high pressure, impact, and mechanical stress.

Aesthetic Appeal

The metallic luster and smooth finish make it suitable for structural and decorative applications.

Easy Installation

DN150 galvanized steel pipes are often threaded for quick and straightforward assembly and disassembly.
