What is titanium?
Titanium is a metal that can be found in nature. It’s also known as titanium dioxide or TiO2 and it’s often used in paints, plastics, surgical equipment and other products.
Titanium is a metallic element that has an atomic number of 22 (meaning it has 22 protons). This means it’s part of the same group as iron (Fe), nickel (Ni) and cobalt (CO). The word “titanium” comes from Latin for tin ore (“tinca”).
How many titanium grades are there?
-
Titanium Grade 1-4 is pure Titanium, the other grades are alloys. Pure Titanium is used due to its high corrosion resistance, the alloys because of the extremely high strength to weight ratio.
-
Grade 1. Pure Titanium, relatively low strength and high ductility.
-
Grade 2. The pure titanium most used. The best combination of strength, ductility and weldability.
-
Grade 3. High strength Titanium, used for Matrix-plates in shell and tube heat exchangers.
-
Grade 5. The most manufactured titanium alloy. Exceedingly high strength. High heat resistance.
-
Grade 7. Superior corrosion resistance in reducing and oxidizing environments.
-
Grade 9. Very high strength and corrosion resistance..
-
Grade 12. Better heat resistance than pure Titanium. Applications as for Grade 7 and Grade 11.
-
Grade 23. Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for surgical implant.

What are titanium pipes used for?
Titanium pipes are used in many different industries. They can be found in the oil and gas industry, the aerospace industry, and even the medical industry. Titanium pipes are also used for chemical applications such as pharmaceuticals or cosmetics. These pipes have been on the market for decades due to their durability and strength.
How are titanium pipes made?
Titanium is melted, and then cooled in a mold. This process allows for seamless or welded construction. The pipes can be made in any diameter or length and come in a variety of shapes: round, square, hexagonal and octagonal.
What qualities make titanium pipes a high-performance option?
Titanium pipes are made from titanium alloys. These alloys have high strength-to-weight ratios, which means they’re extremely durable and resistant to corrosion.
Titanium also has an excellent resistance to high temperatures, which makes it ideal for use in refineries and chemical plants where heat is an issue.
It’s important to note that titanium doesn’t just resist corrosion; it actually forms a protective layer on the surface of the metal when exposed to water or other liquids (this can help prevent rusting). This makes it even more useful in wet environments where corrosive materials may be present–for example, in pipelines carrying fuel oil through pipelines made out of other metals such as iron or steel.
Other forms of titanium pipe
There are many other forms of titanium pipe. These include:
These items can be made from both steel and titanium materials. They all have different applications for the industry but they all share one thing—they’re durable!
Titanium pipes and fittings
Titanium pipes and fittings are used in a wide range of industries. One of the most common uses for titanium is in the aerospace industry, where it’s used as a replacement for steel or other materials. Titanium has been around since the 1950s, but its popularity increased with the advent of space exploration programs that required strong and lightweight materials to withstand high temperatures and pressures while being exposed to cosmic radiation.
Another area where titanium may be found is oil and gas drilling operations. Since titanium can withstand extreme heat, it’s often used during this process when working with hot water (or even steam) at great depths below ground level—a job which requires special equipment such as pumps that operate at very high pressure levels (upwards of 30 bar). In medical applications, surgeons often use implants made out of this material because they’re more durable than those made from other types such as gold alloys or ceramics like silicon carbide which tend not only break down faster over time but also release toxic elements into their surroundings once exposed directly against living tissue without any protective covering whatsoever…
Titanium has many great properties that make it an ideal material for piping in commercial, industrial, and even residential applications.
Titanium is a strong, corrosion-resistant metal that’s lightweight, making it an ideal material for piping in commercial, industrial and even residential applications. It also has a high coefficient of thermal expansion that won’t contract with changes in temperature or pressure over time.
Titanium tubes are used for a variety of purposes including aerospace and military applications where extreme heat or cold may be encountered during flight.
