Steel Tubes

4 Vital Applications Of Stainless Steel Tubes

Steel Tubes

When thinking of pipes, have you ever faced a head-scratching moment when thinking about safety, durability, and strength? Well, there are several solutions to that. One of them is using a 321 stainless steel tube.

By itself, stainless steel is not a naturally occurring metal. It is an alloy of chromium and iron as the main element. Chromium plays a vital role in reducing corrosion.

Increasing the percentage of chromium translates to increased resistance to corrosion. Other elements that are included in the alloy are molybdenum, nickel, manganese, silicon, and carbon. It is vital noting that these elements are added in varying proportions depending on the desired end product.

Applications

Stainless steel tubes are not restricted to round shapes. They can be oval, flat, and even rectangular-shaped and It all depends on the intended use. However, it is imperative noting that tubes are usually available in varying grades such as the 321 stainless steel tube. The following are some of the applications of stainless steel tubes.

  1. The auto industry

Ever came across a rumbling car? If you have, chances are the muffler was made out of a stainless steel tube. Car mufflers are in most cases located under the vehicles, and this makes them vulnerable to the elements. Corrosion occurs when oxygen reacts with metals to form an oxide.

If wrong metal materials are used, corrosion can prove to be an expensive affair if car exhaust systems are anything to go by.

  1. Production lines

Since the invention of the production line, more products can get to the consumers within a record time. However, it is imperative having in mind that improper handling of some products during manufacturing can result in some illnesses or the goods going bad.

To write-off the possibilities of such eventualities, some safety measures must be met. Milk, water, soft drinks, alcoholic beverages, and other liquids need handling with maximum safety in mind. And one of the best ways of achieving that is by using stainless steel tubes when transferring fluids between vessels.

  1. Gas lines

Since its discovery, the domestic or cooking gas has proved to be a valuable commodity over the years. Whether at home or in a commercial kitchen, you don’t want to take chances when handling this commodity. The most suitable method of getting it to your burner(s) is through stainless steel piping.

Why preferably stainless steel over other metals? Over time other metal may be susceptible to corrosion which can prove costly and sometimes undetectable if the corrosion occurs from the inside.

  1. Construction

Stainless steel tubes are also used in construction. Their strength can be instrumental when considering a building’s stability. It is also vital noting that using piping with a low resistance to corrosion in buildings can prove costly when doing repairs

Stainless steel tubes offer the best resistance to corrosion and especially from inside the pipes.

Summary

The applications of stainless steel tubing are vast. From the uses mentioned above, three things are evident. They keep corrosion away, maintain safety, and don’t subject you to losses. They come in various specifications, and one such example is the 321 stainless steel tube.

Nickel

All You Need to Know about Nickel

Nickel

This is a hard and shiny metal with a number of applications for our daily life. You can find it in batteries as well as stainless steel used in making surgical tools and as nickel alloy 20 tubing.

Characteristics of Nickel

  • It is a strong metal that can react with oxygen
  • It combines with iron to achieve its stable property
  • Nickel alloy 20 tubing is corrosion resistant and can be used to strengthen other metals
  • It is easy to shape into different shapes like cylindrical tubes, wire, and rods

Although nickel is said to be one of the most abundant metals, it is not easily found on the surface of the earth.

Extraction and Production of Nickel

Nickel mining is done in 23 countries around the globe. Its extraction is done from sulfides that contain about 1 percent nickel.

The mining of nickel sulfides can be highly labor-intensive since the ores need to be mined from very deep into the earth’s surface. This also makes the process expensive and eventually affects the price of nickel. The mining process may vary according to the area where it is done, for example, the sulfides mined in Canada are more expensive to mine than those in Siberia.

To extract nickel, impurities are removed from the sulfides, but usually, these impurities will contain other valuable minerals.

The production process will involve different stages which may include smelting, the addition of chemicals that can separate the ores, magnetization as well as drying in a furnace.

Usage

There are several ways in which nickel is put to use, but the most common would be in the making of batteries as well as creating alloys like stainless steel. Around the world, nickel is utilized in over 300,000 ways.

The making of stainless steel accounts for over 60% of the use of nickel. There are different types of stainless steel including some that are magnetic as well as non-magnetic steel.

Nickel can be combined with other metals to make strong alloys like the 300 series which are highly corrosion resistant. Different alloys are made using nickel and the way they are made is determined by what they are intended to be used for. The amount of nickel used in making the alloy also varies depending on how resistant to corrosion it is supposed to be.

History of Nickel

Ancient Chinese documents from the 1500s indicate that they were mining nickel already. At that time they referred to it as white copper which was probably because of its combination with silver. Later on in 1751, Alex Fredrich is recorded to have extracted the first pure nickel.

There are also reports of extracting copper from nickel in Germany where they referred to it as “the devil’s copper” since it contained the poisonous compound arsenic.

It was not until 1889 when nickel was presented as a metal that can be used to strengthen ordinary metals. This raised demand for it and after world war II there was an even higher demand for nickel which is now mined on a large scale and used in different applications.
