Advantages of Automatic Blowing System in Galvanizing Steel Pipes
What are the advantages of an automatic blowing system?
- Removes mill scale
- Low cost
- High impact resistance
The automatic blowing system in galvanizing steel pipes is one of the most advanced methods of producing this type of pipe. It ensures that the galvanized pipes’ walls and outer surfaces remain clean and free from any contaminants that may affect their functionality later on. Although the primary importance of the blowing function is to remove any unwanted substances from the steel material, they have lasting benefits for the galvanized steel that can make them last up to 17 decades.
The primary advantage of the automatic blowing technique is that it removes any mill scales from the galvanized pipe, improves its impact resistance, and protection. All of these considerations make this kind of method a cost-efficient and low-maintenance option.
Although the process is often associated with petrochemical plants that involve oiler systems and pipeline networks, the blowing method proves to be useful in the galvanizing process. Continue reading to learn more.
Removes Mills Scale
Steel pipes are manufactured through two methods — hot rolling and cold rolling. In this process, a steel sheet passes through a roller system that joins two opposite ends of the sheet together. This creates the unique cylindrical pipe shape that can be welded or seamed together, cooled, and cut according to size before any post-processing techniques to ensure its quality.
The need for post-processing is dependent on any defects in the steel pipe that may have been inadvertently caused by the various pipe manufacturing phases. Some of these defects are often residual in nature, such as the case with mill scales.
Mill scales are usually iron oxides or rust that appear powder-like on the steel material. Although they don’t have any implications on the quality of the pipe, they may become unsightly to look at and may even speed up the process of corrosion in the pipes.
In the galvanizing process, these mill scales have to be removed during surface preparation so that the zinc coating will properly adhere to the pipe. This is made possible by the automatic steam blowing process that thoroughly cleans the pipe and eliminates any other kind of impurities that may be found therein.
Aside from mill scales, automatic steam blowing also helps in the removal of any excess zinc. Likewise, this does not really have any direct effects on the quality of the steel pipe, but it can lead to a non-uniform appearance. Excess zinc oftentimes appears in the form of dross which is crystallized zinc that is formed by the metallurgical reaction. Steam blowing can easily remove this and improve the overall appearance of the pipe.
Low Cost
The automatic blowing method of pipe galvanizing also proves to be a low-cost option compared to other techniques. Stainless steel pipe manufacturing, in particular, can become expensive due to the complexity of the fabrication process. This makes galvanizing steel pipes more affordable when using them for different types of applications.
Galvanized steel pipes are budget-friendly options for plumbing systems for buildings, residential spaces, irrigation, or even sewer lines. As mentioned before, they can last several decades — even more than a century — with minimal maintenance and repairs required.
All of these are ensured by the steam blowing method that totally cleans the galvanized steel pipe in a single process. If you’re planning to install these types of pipes in your home, you’ll be able to spend less time-consuming and costly efforts in cleaning them.
High Impact Resistance
Automatic blowing generally removes any kind of residue trappings that are found in galvanized steel pipes. When left unaddressed, some of these residues may have performance impacts on the pipes that can affect their sturdiness. Grease, dust, and debris, for example, may contain substances that may cause a chemical reaction to the pipe. This may lead to unwanted pitting corrosion that causes irreparable holes in certain portions.
The steam blowing technique, however, improves the pipe’s impact resistance, due to the absence of any factors that can cause negative chemical or metallurgical reactions. All kinds of fluid transmission/conveyance can be done safely, without affecting the physical dimensions of the galvanized steel pipe.
Key Takeaway
The automatic blowing system in galvanizing steel pipes has several advantages. Primarily, it helps in removing any excess zinc or dirt that may be caused by the production process. Meanwhile, as an after-effect, using the steam blowing system on the pipes makes them a cost-friendlier option compared to stainless steel due to the high impact resistance that they provide.
The next time you’re choosing the best kind of pipe for your plumbing, it’s better to consider galvanized steel pipes, as they exhibit comparable performance and durability compared with stainless steel.
