The term pipe or tube refers to circular, square, rectangular and elliptical hollow sections. And it used for pressure equipment, mechanical applications and instrument systems. Additionally, steel tube has a large number of use cases in various industries including construction. It is also under construction. They are not only used to develop buildings, from small storage units to skyscrapers, but also to manufacture the tools needed to build these buildings. In meantime, they are durable and highly customizable. Different steel alloys can be made by changing the carbon content and adding other elements. Such as nickel, chromium, silicon, manganese, tungsten, molybdenum and vanadium.
How Steel Tubes Made, No Matter Seamless Tube or Welded Tubes?
Seamless steel tube
Like pipes, steel tube can also be seamless or welded. Seamless steel pipe and tube is a solid steel block, which is rolled into a circle, then pierced and stretched to the final length. Imagine having a dough and rolling it into a cylinder. Then put your finger through the middle and use the extra dough to make it longer.
Welded steel pipe tubes
This is its production mode, but it is hot, rotating, and completely completed by machines. On the other hand, welded steel pipes are made of coils. The coil is cut, then rolled into a circle, and the two ends are welded together. From there, the tube pipe can be simply cut into a circular pipe of a certain length, and can also be further changed into other shapes, such as square, rectangular, oval, etc.
Specification Of Various Steel Tubes
As professional steel tube manufactuers around the world. Generally, they have sufficient stocks, including various carbon pipes and other steel tubes, to meet different construction or manufacturing needs. Durable steel tube products can be bent or easily cut and manufactured, which are round, square or rectangular.
Square and rectangular steel tubes
Square and rectangular shapes tubes A-513 (less than 2 inches or 11 sizes) are suitable for mechanical applications up to 24 feet in length.
Structural steel
About structural steel, its A-500 normally is as more than 2 inches and 11 inches. Additionally, it is usually used for trailers, frames, shelves and shelves, and the stock length can reach 48 feet.
Round pipes
The mechanical carbon steel round pipe in A-513. It has various sizes and wall thicknesses, and the stock length can reach 24 feet.
Steel Prices Trend
2023 does not start with the big bang like 2021. We are unlikely to see such a market in the short term as the beginning of 2021, but to be fair, the current market is stronger for steel mills than a year ago. Recall that at the beginning of 2022, we saw the supply catch up with the demand and then exceed the demand. At that time, FOB factory prices were much higher. At the beginning of 2022, the hot-rolled coil (HRC) is 1600 dollars/ton (80 dollars/ton)!
