Ống tôn mạ kẽm là gì?What are galvanized steel pipes?

Galvanized steel pipes are steel pipes that have undergone a specialized coating process to resist corrosion and increase the lifespan of the pipes. These pipes are typically made of carbon steel and coated with a layer of zinc, creating a protective barrier between the steel and the surrounding environment. The zinc coating not only provides exceptional rust and corrosion resistance but also enhances the overall durability of the pipes.

Manufacturing process

The manufacturing process of galvanized steel pipes involves several steps to ensure the final product is durable and reliable. Here is a brief overview of the process:

• Cleaning: The steel pipes are thoroughly cleaned to remove any impurities or dirt, ensuring proper adhesion of the zinc coating.
• Pickling: Subsequently, the pipes are immersed in an acid solution to remove mill scale or oxides present on the surface. This step further prepares the steel for the electroplating process.
• Galvanizing: The cleaned pipes are then immersed in a molten zinc bath. Through a metallurgical reaction called hot-dip galvanizing, zinc forms a tightly bonded coating on the surface of the steel.
• Cooling and inspection: After galvanizing, the pipes are cooled and inspected to control quality. This step ensures a uniform zinc coating with no defects.

Benefits of galvanized steel pipes

Galvanized steel pipes offer various benefits, as listed below:

• Superior durability: Galvanized steel pipes are known for their exceptional durability. The zinc coating acts as a sacrificial layer, protecting the steel underneath from corrosion and extending the pipes’ lifespan.
• Corrosion resistance: The primary benefit of galvanized steel pipes is their superior corrosion resistance. They can withstand harsh environmental conditions, including moisture, chemicals, and even contact with soil.
• High longevity: Due to their excellent corrosion resistance, galvanized steel pipes have significantly higher longevity compared to regular steel pipes. They can last up to 50 years or more, reducing the need for frequent replacements.
• Low maintenance: Galvanized steel pipes require minimal maintenance throughout their lifespan. The zinc coating acts as a self-healing barrier, ensuring that minor scratches or abrasions do not compromise the integrity of the pipes.
• Flexibility: Galvanized steel pipes are suitable for a wide range of applications, including water supply systems, plumbing systems, gas pipelines, outdoor structures, fencing, etc. They are compatible with various fittings and connectors, providing flexibility in installation.
• Cost-effectiveness: While galvanized steel pipes may have higher initial costs compared to some other materials, their long lifespan and low maintenance requirements make them a cost-effective choice in the long run.

Specification of galvanized steel pipes

When specifying galvanized steel pipes, providing accurate and detailed information is essential to ensure the pipes meet the desired requirements. Here are some key factors to consider when specifying galvanized steel pipes:

• Pipe size: Specify the nominal pipe size of the galvanized pipes based on the intended application. They have the same basic nominal sizes as regular steel pipes.
• Length: Specify the desired length of the galvanized pipes. Common lengths include 6.4 meters or 7.3 meters, with custom lengths available if needed. Consider transportation and installation requirements when determining the pipe length.
• Coating thickness: Specify the requirements for the zinc coating. Galvanized steel pipes typically have a hot-dip zinc coating, but you can also specify alternative coating options if necessary. This includes specifying the thickness of the zinc coating.
• Standards and specifications: Identify the relevant standards and specifications that the galvanized pipes must meet. This may include standards set by organizations such as ASTM International or ANSI.
• Quantity: Specify the quantity of galvanized steel pipes required for the project. This ensures accurate procurement and delivery.
  Additional requirements: Specify any additional requirements, such as specific threading, end connections, or special testing needs.

Additional requirements: Specify any additional requirements, such as specific threading, end connections, or special testing needs.

Applications of galvanized steel pipes

Galvanized steel pipes are widely used in various industrial, commercial, and residential applications. Some common applications include:

• Water supply systems: Galvanized steel pipes are widely used to transport drinking water in residential and commercial buildings. Their corrosion resistance ensures the delivery of clean and safe water.
• Plumbing systems: These pipes are often used for installing plumbing systems due to their durability and reliability.
• Gas pipelines: Galvanized steel pipes are an ideal choice for gas pipelines because they can withstand pressure and provide a safe conduit for natural gas distribution.
• Outdoor structures: The corrosion resistance of galvanized steel makes it a popular choice for outdoor structures such as handrails, fencing, guardrails, and signage.
• Irrigation systems: Galvanized steel pipes are suitable for irrigation systems due to their ability to withstand moisture and soil conditions.

Price of galvanized steel pipes

There are various price ranges on the market, but below is the latest price range for your reference:

• Price range: 24,100 – 726,000 VND per pipe
• Pipe length: 6 meters
• Pipe specifications: D12.7 – D113.5
