Pros and Cons of Galvanized Steel Pipes
Galvanized pipe is becoming more and more popular among people. This is because hot-dip galvanized steel pipe has the advantages of uniform coating, strong adhesion, and long service life. Hot-dip galvanizing is to pickle the steel pipe first. After pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution of ammonium chloride and zinc chloride mixed aqueous solution bath and then sent to hot-dip galvanizing bath. After galvanizing, the steel pipe is extremely resistant to corrosion. Next, we take you to know what are the benefits of using galvanized steel pipes.
Galvanized steel pipes have many uses in residential and commercial buildings. Generally, these pipes are used to transport oil, water, natural gas, and other types of liquid substances. These pipes are made of solid steel and come in a variety of forms. Currently, one of the most common and popular types of pipe is galvanized pipe. Galvanized pipe is made of solid steel with an additional coating of zinc. This zinc coating is used in order to avoid rust and corrosion. The schedule of the pipe indicates the thickness of the inner wall of the pipe. The higher the number in the schedule, the thicker the pipe is. If you use schedule 40 pipe in your residence, you will get more benefits. Since it does not rust or corrode, the pipe will not have any leaks and you can use it for years.
Galvanized Pipe Process
In the majority of cases today, steel manufacturers will galvanize a piece of steel by dipping it into a vat of molten zinc. When this happens, the zinc bonds itself to steel in a similar way to any other alloy – it becomes an actual part of the chemical composition of the steel itself.
This means that between the steel and zinc is a gradient mixture of both compounds that combines their properties. This is known as hot-dipped galvanization, and is the most common process. There is another process where zinc is sprayed onto the steel instead, but this process creates a weaker zinc layer and isn’t as common.

Pros of Galvanized Pipes
1. Durable Coating
Galvanization provides a strong layer for steel pipes. Galvanizing not only prevents rust but also greatly increases the life span of the steel pipe. If a steel pipe is known to last up to 50 years, galvanizing can extend its life by another 50 to 80 years. In many cases, the corrosion resistance of some steel tube products is often not up to the required level. This requires frequent maintenance work to be carried out on it in subsequent stages. Some people choose to paint or apply a dry coating to the surface of the pipe to protect the material. But galvanized steel pipe will save you this step. Its galvanized coating is very durable and does not require much maintenance. So you don’t need to spend too much effort on it.
2. Cost-effective
Galvanized tubes compared to stainless steel tubes
Galvanizing has been the preferred method over other types of coatings because of its relatively simple process, easy availability of raw materials, and reasonable price. While aluminum may be a cheaper option for corrosion-resistant materials, it can have drawbacks in terms of strength properties. Meanwhile, stainless steel tubing can be expensive and uneconomical for small applications. This makes galvanized pipe the most cost-effective solution. If your project is relatively small and your budget is low. Then galvanized steel pipe is your best choice.
3. Wide Range of Uses
Galvanized steel pipe is often used in a variety of industries because of its excellent corrosion protection. It has been used for more than 30 years as a material for water supply piping in homes and businesses. It is also a suitable material for sewer pipes. In addition to water and sewer piping, galvanized pipe has many other uses, including fences, railings, scaffolding, and farm irrigation systems. Although it has many uses, it cannot be used for gas piping. This is because when the zinc begins to flake off, it can clog the pipe. Flaking zinc can also cause galvanized steel pipes to burst. You can determine if galvanized pipe is suitable for your project based on the environment you are using it in.
4. Easy to Install
Did you know that in addition to having a strong protective surface, galvanized steel pipe is easy to install? Galvanized steel pipe is readily available and you do not have to purchase another coating to apply to the surface of the pipe. This will greatly reduce the construction time and ensure that you can complete the project at a much faster pace. There are many manufacturers of galvanized pipes on the market today. You can buy from the manufacturers and sometimes they offer installation services that will save you even more.
5. Increased Pressure Ratings
The galvanized round pipe has increased pressure rating. It has the great ability to increase the withstand pressure of the liquid substances. It is also easy to calculate the pressure of the galvanized pipe than the other type of pipe. Though the galvanized pipe is expensive than the other type of pipe for the extra coating, you will get the extra benefits from it as well.
6. Good Shape and Durable Wall
The extra coating of the zinc in the galvanized pipe ensures the thick and uniform pipe from all side. So, there is no chance of spillage and loss of the water or other liquid substances, if it transfers with the galvanized pipe. Welding pipe includes heat, stress, and the other forming process, which can affect the things inside the pipe but galvanized pipe is always safe to use.
Cons of Galvanized Pipes
Despite their longevity and corrosion resistance, galvanized coatings are still subject to chipping, cracking, and similar damage. Using it on bollards designed to protect retail storefronts from vehicle damage, for example, can mean plenty of dings, scratches, and chips. The exposed metal rusts in reaction to the elements and spreads corrosion throughout the rest of the pipe or bollard. This eliminates any rust protection the coating provides. Powder coating over galvanized bollards also means bubbling and chipping issues.
Pipes and bollards are heavy enough without adding galvanization to the equation. In addition to heavy handling, galvanized pipes and bollards are frequently environmental hazards. Any damage they sustain means rust may run into nearby drains, therefore polluting waterways and harming animal life. This is one of the many reasons galvanized piping is rarely used in the state of California anymore.
Additional galvanization disadvantages include the cost. Galvanizations add up to .50 cents per pound of piping to the final installation price. It also costs you more money in the event of any damage because the pipes or bollards will have to be replaced instead of just repaired.
The negative aspects of using galvanized pipelines as well as bollards much surpass the benefits. They are an expensive, eco-UNfriendly selection you should possibly prevent.
Conclusion
When you collaborate with Wanzhi Steel, you will certainly not handle the issues coming from galvanization. We use zinc primer instead of galvanized materials to layer our bollards, which lasts much longer and also is very efficient. It is also ecologically safe as well as works well with powder coatings. You will consequently appreciate high-grade, environment-friendly, cost-efficient bollards, whether you need them for your university or college, retail facility, restaurant, stockroom, or other business or company.
