With the rapid development of the modern construction industry, various types of building materials are emerging in endlessly. Among them, galvanized tube, as an important pipe material, has attracted much attention due to its excellent performance and wide range of application fields. This article will provide a detailed introduction to galvanized pipe to help you solve your work needs and better understand this material.

How to learn about:

  • What is galvanized pipe
  • Classification of this type of tube
  • Performance, specifications and uses

Galvanized Pipe

1. What is galvanized pipe?

Galvanized pipe refers to a pipe that is galvanized on the surface of the steel pipe.
Galvanizing is a metal anti-corrosion method. By covering the metal with a layer of zinc, it can effectively prevent the metal from corrosion. This not only allows it to inherit the advantages of steel pipes such as strength, pressure resistance, and ease of installation, but also increases anti-corrosion performance and improves service life.

2. Classification of galvanized tubes:

Galvanized pipes can be divided into hot-dip galvanized tubes and cold-dip galvanized tubes according to the production process.

  • Hot-dip galvanized pipe adopts hot-dip galvanizing process, with thick zinc layer, strong adhesion and excellent anti-corrosion performance;
  • Cold-dip galvanized tubes use electroplating technology and have a bright appearance, which is suitable for some occasions that require high aesthetics.

3. Key points to note about galvanized pipes:

(1.  Strong anti-corrosion performance: The galvanized layer can effectively prevent metal from corrosion and extend the service life of pipes.

  • However, the zinc layer of the hot-dip galvanized pipe is closely combined with the steel pipe matrix to form a zinc-iron alloy layer, so it has better corrosion resistance.
  • In contrast, cold-dip galvanized tubes (electro-galvanized) have a thin zinc layer and poor corrosion resistance, and have been gradually phased out.

(2.  Specifications and standards: Galvanized tubes have different nominal wall thicknesses and corresponding weight coefficients. These parameters are formulated according to different usage requirements and standards.

  • For example, GB/T3091-2015 specifies the standards for welded steel pipes for low-pressure fluid transportation;
  • Other standards such as GB/T13793-2016 stipulate information such as the size and unit length weight of straight seam electric welded steel pipes.

(3.  Usage: Galvanized pipes are widely used in water delivery and heating systems in the construction industry, as well as as pipelines for low-pressure fluids such as gas and oil. In addition, it is also used in offshore oil fields, chemical equipment and various industrial structural parts.

Galvanized Pipe

To sum up, galvanized pipe is one of the important products in the steel pipe industry. It improves the durability and application fields of the material through special processing technology. When choosing, you should choose the appropriate type and specification according to your needs, and pay attention to the quality and relevant standards of the product.
