Product Advantage
Galvanized steel pipes have been a reliable choice in plumbing for many years, thanks to their robust construction and protective zinc coating. These features offer several advantages that make them a viable option for various applications.
1. Durability
When properly maintained, galvanized steel pipes can last between 40 and 100 years. The wide difference in lifespan is mainly due to the varying levels of environmental factors such as water quality and exposure to corrosive elements.
2. Corrosion Resistance
The zinc coating provides a protective barrier against rust and corrosion by keeping out moisture, which can significantly extend the pipe’s lifespan compared to non-galvanized steel. While the zinc layer's effectiveness can vary depending on the environment, it typically rusts much slower than untreated steel, at about one-thirtieth the rate.
APPLICATION
1.Industrial and Commercial Buildings
Galvanized steel pipes are highly durable and resistant to corrosion, making them suitable for industrial and commercial buildings. These pipes can handle high pressure and are less likely to suffer from leaks or bursts, ensuring a long-lasting plumbing system that requires minimal maintenance
2.Budget-Conscious Projects
For projects where cost is a significant factor, galvanized steel pipes can be an economical choice. They are generally less expensive than some modern materials, providing a cost-effective solution for plumbing systems without compromising on strength and durability.
Packing &Shipping
Steel pipe suppliers know that it is very important to protect galvanized steel pipes for transportation after delivery. This is because without a protective coating, steel can easily rust, a process known as corrosion. Therefore, before shipping the pipe, manufacturers usually apply a layer of oil to the galvanized metal to slow the reaction of the zinc with the air. When this oil coating wears off, the zinc reacts with oxygen to produce a fine white film that changes the color of the metal from gray to a more unsightly off-white. When galvanized steel pipe needs to be imported, this type of pipe will usually have a passivation film to protect the metal from corrosion in the saltwater environment when it travels across the ocean on a cargo ship. When exposed outdoors, this passivation will weather within six months; when used indoors, it can be removed by etching the surface with a phosphoric acid solution.
