If you’re in the market for galvanized pipes, you may have heard references to ASTM standards. But what are these standards, and what do they mean for your galvanized pipe purchase? In this article, we’ll explore some of the most common questions about ASTM standards for galvanized pipes.

What is the ASTM standard for galvanized pipe?

The American Society for Testing and Materials (ASTM) has developed a set of standards for galvanized pipes. These standards ensure that galvanized pipes are produced and tested to meet certain specifications, including strength, corrosion resistance, and durability.

The most commonly referenced ASTM standard for galvanized pipes is ASTM A53. This standard covers seamless and welded black and hot-dipped galvanized steel pipes in nominal sizes ranging from 1/8 to 26 inches. In addition to ASTM A53, there are other ASTM standards for galvanized pipes, including ASTM A123, ASTM A153, and ASTM A106.

Is ASTM A53 galvanized pipe?

ASTM A53 covers both black and hot-dipped galvanized pipes. However, it’s important to note that not all pipes that meet ASTM A53 standards are galvanized. You’ll need to look for additional specifications to ensure that the pipe you’re purchasing is galvanized. To be considered galvanized, a pipe must be coated with a layer of zinc to protect it from corrosion. This process is known as hot-dip galvanizing.

What is the difference between hot galvanizing and cold galvanizing?

What is the difference between ASTM A53 and A106?

ASTM A53 and ASTM A106 both cover seamless carbon steel pipes. However, ASTM A53 is intended for pressure and mechanical applications, while ASTM A106 is intended for high temperature service. ASTM A53 is commonly used for water and gas lines, while ASTM A106 is used for high temperature applications such as refineries and power plants.

In conclusion, if you’re looking for galvanized pipes, it’s important to ensure that they meet the appropriate ASTM standards. ASTM A53 is the most commonly referenced standard for galvanized pipes, but be sure to check for additional specifications to ensure that the pipe you’re purchasing meets your needs. By understanding the differences between ASTM standards, you can make an informed decision about which galvanized pipe is right for your project.
