What is galvanized pipe?
Content list
Galvanized pipe is one of the most used pipes in the industry. This type of pipe is made of metals that are vulnerable to corrosion. For this reason, at the time of production, a coating of another metal is placed on them, which is resistant to corrosion. In fact, with this coating, the metal pipe is protected against corrosion, which is done through galvanization. For this reason, this tool is called galvanized pipes.
Therefore, it can be said that it is a steel pipe whose surface is covered with a metal layer, which is generally zinc and iron, to be resistant to corrosion. Increasing the resistance of this pipe model against corrosion and minerals increases its lifespan. These features made this pipe to be used as the most common water transfer pipe. Galvanized pipes are divided into two categories, galvanized steel and iron, based on the material.
Galvanized iron pipe
One of the most interesting features of this tube is its color recognition. The color of this tool is gray and dark and usually buyers identify and buy it through its color. This pipe is produced from white rolled iron and includes two types of light and medium. Another feature of this pipe model is its seams, which are connected through welding machines. For this reason, this pipe model is called spiral tubes.
Galvanized steel pipe
This type of pipe, which is more common in Iran, is produced from mild steel. In this way, first it is passed through the mold and with pressure, and then it is placed in the zinc plating bath, or galvanized, to increase its resistance against metal corrosion factors. This pipe is also seamed like the iron pipe. with the difference that it is more shiny and lighter than the iron type. Of course, the resistance of this pipe against acids is lower than iron pipe.
Galvanized Iron vs. Galvanized Steel Pipes:
Choosing between galvanized iron and steel pipes can be challenging. Both types of pipes have their own advantages and disadvantages that should be considered before making a purchase.
Key Differences:
Material: Galvanized iron pipes are made from wrought iron, while galvanized steel pipes are made from rolled steel.
Weight: Galvanized iron pipes are generally heavier than galvanized steel pipes of the same diameter.
Strength: Galvanized steel pipes are generally stronger and more durable than galvanized iron pipes.
Corrosion Resistance: Both types of pipes are protected with a galvanized coating, but galvanized steel pipes are less resistant to acids.
Price: Galvanized iron pipes are generally less expensive than galvanized steel pipes.
Applications:
Galvanized Iron Pipes: Suitable for general applications such as water, sewage, and HVAC piping.
Galvanized Steel Pipes: Suitable for heavier applications such as water transmission lines, steam pipes, and structural steel.
The following table provides a summary of the key differences between galvanized iron and steel pipes:
