A guide to 125-degree galvanized steel pipes

A 125-degree galvanized steel pipe is a highly corrosion-resistant steel pipe coated with a protective zinc layer through an immersion process in molten zinc. This galvanization enhances its durability, strength, and environmental resistance, making it suitable for a wide range of applications.

1. Manufacturing Process of Galvanized Steel Pipes

The production of galvanized steel pipes involves several key steps to ensure high-quality corrosion protection and structural integrity.

Material Preparation: Selection of high-quality steel.

Pickling: Removes rust and impurities from the surface.

Hot-Dip Galvanizing: The most commonly used method, involving:

Pickling

Water washing

Drying

Immersion in molten zinc

Cooling

Removal of zinc slag

Cold-Dip Galvanizing: An alternative process with different adhesion properties.

Among these, hot-dip galvanizing is the preferred method due to its strong, uniform zinc coating that provides long-lasting protection.
