Q235 ERW pipe

Galvanized ERW steel pipe

Hot-dip galvanized steel pipe is a kind of steel pipe treated by galvanizing process, which has excellent anti-corrosion performance and long service life. The manufacturing process involves immersing the steel pipe in a molten galvanizing solution to attach a uniform layer of zinc to its surface. 

This kind of steel pipe is widely used in construction, transportation, water conservancy and other fields, and plays a role of structural support and protection. Its length can be customized according to demand, the common several meters to tens of meters. Due to its excellent corrosion resistance, hot-dip galvanized steel pipes show good durability in harsh environments, greatly extending the service life and reducing maintenance costs. In short, hot-dip galvanized steel pipe is an efficient and reliable metal pipe, which provides a solid support for various projects.

 Specification parameters

High Frequency ERW (Electric Resistance Welded) Pipe is a type of steel pipe manufactured through a process that uses high-frequency current to heat and fuse the edges of steel strips, forming a strong and uniform weld seam. This production method ensures high efficiency, stable quality, and consistent dimensional accuracy, making ERW pipes widely used in structural and industrial applications.

These pipes are known for their excellent mechanical properties, including high strength, good toughness, and reliable pressure resistance. The smooth internal and external surfaces reduce fluid friction, making them suitable for transporting water, oil, gas, and other fluids. They also offer good weld integrity and uniform wall thickness, which enhances overall performance and durability.

High Frequency ERW welded pipes are commonly used in construction, machinery manufacturing, automotive components, scaffolding structures, and pipeline systems. Depending on requirements, they can be produced in various sizes, grades, and surface finishes such as black, galvanized, or coated.

With cost-effective production and strong performance characteristics, High Frequency ERW Welded Pipe remains one of the most widely used steel pipe solutions in modern engineering and infrastructure projects.
