Cold Rolled Round Tubing (Hollow Section)
Find out what are the applications of a hot-dip galvanized Cold Rolled Round Tubing (Hollow Section) and what advantages it offers!

Round Tubing s, especially those that undergo hot-dip galvanizing, are items very popular on the market, especially for their versatility, since they is easy to use in different applications.

With that in mind, in today's article, we'll talk about the applications of a hot-dip Round Tubing , detailing its characteristics and advantages in each different application.

But first, let's learn more about hot-dip galvanizing!

Tube galvanizing: what it is and what are its characteristics

Hot-dip galvanizing is among the oldest and most successful protection processes. The reason for so much success is relevant to the way it is good.

For those unfamiliar, hot galvanizing is the hot-dip galvanizing process. That is, the Cold Rolled Round Tubing (Hollow Section) dips in hot zinc so that their entire surface comes into contact with the material.

The main purpose behind the galvanizing process

The purpose of this process is to prevent the contact of the base metal with the corrosive medium, in order to increase the resistance and, consequently, the durability of the tube.

Due to hot galvanizing, the tubes is easy to use in the most diverse applications, making their presence felt in several projects, especially due to the characteristics acquire after being galvanized.

Among the main features acquired, we can highlight the strength, versatility, durability, and safety that hot-dip Round Tubing have.

What are the applications of Cold Rolled Round Tubing (Hollow Section)?

Get to know some of the most common applications for Cold Rolled Round Tubing (Hollow Section).

Furthermore, what is the best type of Round Tubing?

Hidraulic installations

Yes, once galvanized, the pipes are easy to use without any risk of oxidation in hydraulic installations.

Unlike other conductors, keep in mind that Round Tubing can resist contact with water at different temperatures and pressure levels, which naturally expands its application for use in hydraulic installations.

Hot-dip Round Tubing s, therefore, is common, for example, in artesian wells, hydrants, and supply systems in residential, commercial, professional, and industrial environments.

Petrochemical industries: Cold Rolled Round Tubing (Hollow Section).


The industrial area is undoubtedly one of the right destinations for hot-dip galvanizes pipes. Among the sectors that most resorts to this type of pipe, the chemical and petrochemical industry are certainly the most important.

In these industries, Cold Rolled Round Tubing (Hollow Section) is easy to use in chemical conduction systems.

This is because, after galvanizing, the tube surface becomes anticorrosive, allowing it to come into contact with chemical fluids without reducing its useful life.

The high-definition plasma cutting method consists of an extra channel to output gas expelled by a small-sized nozzle.

What about an oxyfuel process?

Compared to plasma cutting in high definition, the oxyfuel process takes a long time and, often, by operating at low speeds and with less precision to create Cold Rolled Round Tubing (Hollow Section), it prevents very thin stainless-steel sheets from being cut efficiently.

#1: Performance and consistency in the process

The development of the high definition plasma cutting method is largely due to? ? incorporation of technologies that until then we cannot use in the plasma cutting process due to its high cost at the time.

Among the technologies, we have the creation of the Hyperformance process, also known as high-performance plasma. Its coaxial cutting technology allows the high-definition process not only to perform superior to conventional plasma cutting methods but also to offer? a consistency in the process consuming a considerably less energy reserve.

Now let’s check out the main differences here!

#2: Lifetime of Machinery Parts

When a part is subject to the cutting process, it is important that the machinery has good durability, being suitable for mass manufacturing of the necessary products like Cold Rolled Round Tubing 

Certain stainless steel plasma cutting methods, such as oxygen plasma cutting, cause the nozzle to lose its life more quickly.

In technologies that use the high-definition plasma cutting process, the machinery pen has a protection technology that guarantees its use for a longer period of time, allowing the cutting of steel plates for a long time without the need for maintenance nozzle and its channels for the plasma gas output.

# 3 Cutting Quality Requirement

This is possible thanks to the extra channel good for the exit of excess plasma gas, allowing for a higher quality cut and ensuring that your stainless-steel project of creating Cold Rolled Round Tubing (Hollow Section) is easy to execute without wasting energy or material.

The commercialization of steel tubes is one of the great flagships of the mechanical sector. Steel tube applications vary between different functions. Versatility and flexibility make stainless steel tubes ideal as part of structures such as piping and buildings. However, it is necessary to know the differences between the categories of sewn and seamless stainless tubes.

What are the characteristics of each of the above categories?

To help you with this, find out below what are the characteristics of each of these categories. Do you know which design and application are best suit for with seam or seamless stainless-steel tubes?

Check it out below!

Stainless steel tubes with seam

Manufacture of Sewn and Seamless Stainless-Steel Tubes

The manufacturing process is the great differential of stainless-steel tubes such as Cold Rolled Round Tubing (Hollow Section). The seam, in this case, is in relation to how the steel sheet will be deformed in the weld.

The main advantage:

The advantage of this welding process in the manufacture of stainless steel tubes in different formats. The variation of thicknesses, sizes, and diameters makes a difference in the applications of stainless-steel Cold Rolled Round Tubing (Hollow Section) with seams.
