Tubes are some of the most widely used components in the world. However, a plain tube is not enough for every task. There are times when we need to adjust the shape in order to make the tubing fit for purpose. To do this, our team uses tube expansion, in addition to various other procedures.

Titanium is one of the primary materials we use for our products. Overall, it’s the fourth most frequently used structural metal. It is lightweight with a density that’s roughly 50% of copper and nickel alloys, and 60% of steel.

Welded titanium tube comes in a myriad of outside diameters and wall thicknesses. Furthermore, you can test it using many of the methods you’d employ with steel tubing. This includes ultrasonic and pneumatic tests. These tubes also come in a series of grades of pure titanium and alloys. Those grades approved for pressurised service include 1, 2, 3, 7, 9, 11, 12, and 16.

The costs

When it comes to cost, titanium is rather competitive with speciality alloys and steels. In truth, if you look on a life cycle basis, it tends to be more economical. This arises from the metal’s long life, which is typically 20 to 40 years. Its low maintenance demands also contribute to the appeal. Moreover, titanium’s formidable resistance usually permits a zero corrosion allowance. What this means is that you can use thin-walled tubing instead of tubes with heavier, thicker walls.

At Multiform Tubes, we achieve tube expansion via one of two methods. We call the first one ram forming expansion, which we use when operating on specific tubes. The second approach employs a hydraulic operated expanding die and allows for more flexibility with range and size. We will select the right method for each specific product, taking into account the material, wall thickness, and type of finish.
