There are various types of steel available in different shapes, sizes, grades, finishes, and other specifications. One key difference between them is the roll processing method used. Steel-processing takes place using a variety of machines at different temperatures.

If you are looking for seamless tubes for your projects, then it helps to know which type of steel is more suitable for your specification application. The right type of steel can save you a lot of time and money and will help you achieve the desired result. Here’s a quick guide to help you understand the difference between cold drawn steel, hot rolled steel, and cold rolled steel so that you can make an informed decision.

Cold Drawn Steel, Hot Rolled & Cold Rolled Methods

Hot-Rolled Steel Products

 
The processing of hot-rolled steel products occurs at a very temperature, as high as 1000 degrees Fahrenheit, which is above the recrystallization temperature for most grades of steel. This makes the steel easier to form, mould, and work with. Hot-rolled seamless tubes are ideal for making railway tracks, metal sheets, and structural components in construction projects.

Properties of Hot-Rolled Steel Products:

  • Rough surfaces with a rounded appearance
  • Cost-effective and malleable
  • The final form of the product may have slight variations

Cold-Rolled Steel Products

 
Cold-rolled steel products involve roll processing at around room temperature. The recrystallization temperature is kept below the normal. Cold rolled steel is not as malleable as hot-rolled steel. However, the main difference between hot-rolled and cold-rolled seamless tubes is that the latter is stronger. Cold-rolled seamless tubes also have better surface quality and greater dimensions than hot-rolled ones. Cold-rolled steel is ideal where structural finishes and technical precision are important. For example, the automotive and the construction industry.

Properties of Cold-Rolled Steel Products:

  • Greater mechanical strength and tolerance
  • Superior surface finish
  • Seamless tubes have concentric uniformity and straightness
  • If not treated properly, it can lead to unexpected warping

Cold-Drawn Steel

 
Cold-drawn steel is given additional pressure, more than other types of steel to give them the desired shape. Similar to cold-rolled steel, the professing of cold drawn steel happens at room temperature. However, while cold-rolled steel has a flat surface, cold drawn steel has a thin shape like that of a wire or rod.

A few noticeable differences between cold drawn steel and other types of steel:

  • Cold-drawn steel has precise measurements and sharper edges.
  • Cold-drawn seamless tubes have improved tensile strength.
  • Projects that require making structural components can use cold-drawn steel because of its aesthetic appeal. Consumer products such as paper clips, cables, and bolts also use cold-drawn steel.
  • Using cold-drawn steel could lead to high production costs.

The Bottom Line

 
The type of steel you buy depends on what you’re looking to build. Each processing method has its benefits and drawbacks. But having a deeper understanding of seamless tubes and roll processed steel can help you save time and effort and make better buying decisions.

Seamless Tubes

 
A seamless tube, also known as a seamless pipe, is a tube/pipe with no welding seam. It is made of a single piece of metal without any joins. Each end of this tube is connected to another tube without any welding joint. The ends have threads that help in forming a connection with other tubes.

Seamless tubes are made from a solid cylindrical piece of alloys or metals such as stainless steel, tungsten, carbon steel, etc. known as billets. These billets are heated, pierced through the center, and rolled over a form until they take the shape of a hollow tube. The wall thickness of the tube is usually specified as per the requirements of the customers.

Major suppliers of these billets are from Venezuela, Egypt, Qatar, Saudi Arabia, United Arab Emirates, and Oman.

The industries where safety requirements are very high, tend to use seamless tubes. Because these tubes have better pressure capacity, strength is higher as compared to welded tubes.

The seamless tube is a hollow cross-section pipe with no seams. Usually, the maximum diameter of a seamless tube is 650mm and the minimum is 0.3mm. The thickness of the wall depends on the usage.

As there are no joints in a seamless tube, the working pressure can remain much higher as compared to the welded tubes of same size where same material is used. Seamless tubes prevent the probability of flaw and differences in malleability as it does not have any joints. These concerns are usually associated with the welded areas in welded tubes. Moreover, in seamless tubes, it is not required to test the weld strength. Therefore, these are more appropriate for significant and crucial applications.

Welded Tubes

 

Welded tubes are steel pipes made from long, coiled steel plates. These plates are cut into particular lengths that give flat rectangular sheets.

The rectangular sheets are converted into cylindrical shape tubes with the help of rolling machines. These machines work on a high-frequency electrical current that helps the sheets to melt and fuse together. In other words, the rolling application is the process that forges the welded seam or joint. The best part of this process is that no welds are visible in the finished product. And because of these joints, welded tubes are manufactured in long continuous lengths.

The welded sections are inhomogeneous that results in malleability, greater dimensional variation, and less corrosion-resistant feature. Therefore, drawing the tubes is required here. It reduces these deviations. It is a process where a tube is passed through a die.

The production process of welded tubes is simple with a variety of specifications. However, the strength of the tubes is comparatively lower than that of seamless tubes. As less drawing and strengthening is required in the process, the manufacturing cost also comes down.

How are Seamless Tubes Different from Welded Tubes?

How Do Seamless Tubes Enhance the Business Production?

By adminDec 22,2018

Quick Inquiry





captcha

With great tensile strength and a solid round shape, you might have noticed these seamless tubes in many manufacturing units. Someone who is a novice to the workings of the manufacturing units may just find these tubes to be ordinary with no unique feature. These people also believe that these tubes are just pipes which are used to carry liquids or gasses from one place to another.

This blog is for them. Below we have mentioned a few ways the seamless pipes can enhance the business production with its unique qualities that definitely makes it different from the other ordinary pipes.

1. Can Withstand Strong Pressure

This is a very strong advantage of seamless pipes. They have a great ability to withstand strong pressure. This makes them far more durable than the welded pipes as they tend to have a weak point, their weld. Since the seamless pipe does not have a welded seam, there are no chances for it to have a breakdown. The whole circumference of the pipe is strong, with no weak points.

This quality makes it more costly than the normal pipes but can effectively enhance the business production. This ability can also help you to pick a thinner, less costly pipe which can allow you to cut down costs effectively.

2. Uniform Shape

Seamless tubes are a perfect round, how? Because there is no weld. Welding can induce stress and heat among other variables that can affect the shape of the pipe. As seamless pipes are free from a weld, they are of the perfect shape. None of the pipes can be as round as the seamless tube.

Seamless steel pipes have a round cross-section that is formed through the alloy’s continuous extrusion. This is a great advantage in installing and fittings.

3. Great Strength Even When Loaded

Seamless tubes are expensive than the normal steel pipes as we have mentioned earlier, but there is a reason for it. These tubes are highly reliable as they have great load bearing ability.

Any empty pipe can bear its load. The real strength is determined when they have to carry the load. Pipes filled with resources or materials not only have to support their own weight but also the weight of these resources and also carry them effectively from one place to another. Over time, the welded pipes can develop leaks and thus let the whole manufacturing unit come to a halt. This is not the case with seamless tubes, thus helping save the costs involved in the following two aspects:

  • Buying a new pipe.
  • The time lost due to failure and the effect of that time lost in the cost of production.

Sometimes, the latter can cost you more than the former. Thus, foresee these failures and select seamless tubes to run your production or manufacturing unit.

The benefits are endless but these three are the crucial ones that make the seamless tubes the most preferred tubes. There are many variants even among these tubes. The business owners or plant managers use alloy steel seamless tube and/or carbon steel seamless tube the most. Let your business have the same solution by getting these tubes.

The Manufacturing Process of Seamless Tubes

By adminDec 7,2018

Quick Inquiry





captcha

The people who have been in the business of manufacturing seamless tubes will be well aware of the primitive technology of rolling mill, used widely in the nineteenth century. This technique was used to produce seamless pipes and tubes to be used in industries. The whole procedure is long and included the following steps:

  • With the use of funnel rolls, rolled sheets are converted into a cross-sectional circle
  • Through the welding process, the lap welding was carried out on these cross-sectional circle

This all seems to have changed now, thankfully because of the advent of new technological advancements and developments. Due to this, many new processes have surfaced that makes the whole manufacturing process of seamless tubes, easy and cost-effective. But the most popular process that has caught on with many manufacturers in the process of continuous tube mill. No forge welding or filler metal is used in this new technique.

Seamless Tube Manufacturing Process

 

1. Preparing the stainless steel sheets

The stainless steel sheets undergo several checks before getting picked to roll. While preparing them, the first step is to trim them around the edges.

2. Rolling through rollers

The sheets are then passed through many rollers to match the required size. In this step, you can see the sheets progressing into tubular shapes.

3. Rollers Through the fitted welding machine

In this step, the tubular shape has to go through a fitted welding machine. The inside of these tubular shapes, i.e., the weld beads and scraps are removed, thus giving you perfectly rolled tubes.

4. Cleaning and heating of rolled seamless tubes

After the stainless sheets have a basic rolled structure, it goes through the process of cleaning and heating. This depends upon the clients’ requirements. The stainless steel tubes are cleaned thoroughly to remove dirt before the heating process begins. Heating is used to remove the possible stress on the seamless tubes and let it have a seamless shape. The tubular shape is rolled in a hot furnace that has temperature controllers and recorders. The heating process helps the tubes to be straightened and open to pickling and removing the scales from its surface.

5. The cold-drawing process

Many clients have a peculiar tube requirement that will not match the seamless tubes rolled out directly from the mills. For this reason, another process of cold-drawing is to be performed to achieve the desired size.

To manufacture cold-drawn seamless tubes, the manufacturer first coats the tube with soap and oxalic solution. The solution helps to reduce the friction caused due to this process, by acting as a lubricant. Later, the seamless tubes are benched with the help of Die plugs.

6. Final touches

The final touches include ink jet marking on the seamless tubes, that educates the exporters about the tube’s grade, material, heat number, size, and a third party inspection stamp. Followed right after this are several stringent quality checks and appropriate packaging, making these seamless tubes ready for dispatch.

There are several industries that need seamless tubes in different alloys to have varied tensile strength. Thus many manufacturers produce the alloy steel Seamless tube. The most popular among these alloy steel seamless tubes are a carbon steel seamless tube.

How Can You Improve the Seamless Tubes Manufacturing Process?

Manufacturing seamless tubes is a complex process that requires precision, efficiency, and adherence to strict quality standards. However, with the advent of advanced technologies, there are several ways to enhance the manufacturing process. Let’s explore some key strategies for improvement:

Advanced machining technologies, such as CNC (Computer Numerical Control) machining, allow for the precisely shaping and finishing seamless tubes. CNC machines offer high accuracy, repeatability, and the ability to produce complex tube geometries. This technology ensures tight tolerances, smooth surfaces, and excellent dimensional accuracy, meeting the stringent requirements of various industries.

5. Continuous Seamless Tube Mills

Continuous tube mills have revolutionised the seamless tube manufacturing industry. Unlike traditional methods that involve forging welding or filler metal, these mills eliminate the need for these processes. This technology allows for the continuous production of seamless pipes and tubes, resulting in higher productivity, reduced costs, and improved efficiency.

The Evolution of Seamless Tube Manufacturing Techniques

The manufacturing of seamless tubes has come a long way since the nineteenth century. Traditional techniques, such as rolling mills and lap welding, have been replaced by more advanced and efficient methods. Let’s explore the evolution of manufacturing techniques:

Introduction of Continuous Casting

Continuous casting is a significant development in seamless tube manufacturing. It involves the continuous pouring of molten metal into a water-cooled mould, which solidifies the metal into a continuous billet. This continuous casting process ensures better homogeneity and improved mechanical properties of the tubes.

Piercing and Extrusion

Piercing and extrusion are key processes in seamless tube manufacturing. Piercing involves making a hole in the solid billet, while extrusion uses a mandrel to shape the tube and reduce its diameter. These processes have evolved with advancements in tooling technology, resulting in improved accuracy and surface finish of the seamless tubes.

Development of Advanced Alloys

The evolution of seamless pipe manufacturing also includes the development of advanced alloys. High-performance alloys, such as stainless steel, duplex stainless steel, and nickel alloys, offer superior corrosion resistance, high-temperature strength, and other desirable properties. These alloys have expanded the application range of seamless tubes in various industries, including oil and gas, petrochemicals, and automotive.

Steel tubes are quite popularly used in factory and industrial set ups. The steel pipes are used commercially and for a number of purposes. However, it is better to get the seamless tubes, as they are able to withstand pressure for a longer time and do not fall weak easily. The pipes usually fall weak at the welded part, as the seamless tubes are not welded there is no such weak point in the tube. Therefore, for construction or any other commercial purpose, one must use the seamless tube for better efficiency and performance.

What are the Other Benefits of the Stainless Tubes?

The stainless and seamless steel tubes have a variety of benefits and these make to be enough reasons why one must prefer to buy them over the other tubes.

Following are Some of the Benefits of Using the Seamless Tubes:

 

  • A seamless tube is well shaped. The welded tubes do not have uniformity of shape as excess heat is used. The seamless tubes are not welded, so they are uniform in shape and do not have any sharp areas.
  • The seamless tubes may cost a little higher than the other tube types. However, they do not give in at the time of excess pressure. The tubes last for a longer time and carry out desired work even in the extreme weather conditions. So, it is a preferable that these tubes are opted for use.
