The Three Benefits of Seamless Steel Pipe

The time of issue:2014-6-27 9:40:21       Author:

Not similar with API steel pipe, the first step of the manufacturing process of the seamless steel pipe includes a solid and round steel billet. The billet should be shaped as a hollow tube by heating, stretching and pulling. Therefore, there are three benefits of seamless steel pipe in this way, including increased pressure ratings, uniformity of shape and strength under loads.

Firstly, the increased pressure ratings. The ability of the seamless steel pipe to withstand pressure is its greatest advantage. On the contrary, the welded seam is the weakest point in a welded steel pipe. However, we need not to worry about this point of seamless steel pipe, because the seamless steel pipe is not welded, which in turn makes it strong. In addition, even if without taking weld quality into consideration, it is still easy to determine pressure calculations. Compared to the welded steel pipe, the seamless steel pipe is usually expensive, but the ability to withstand pressure allows you to use thinner and lighter pipe, which in turn saves the cost.

The uniformity of shape is the other benefits of seamless steel pipe. Before welded, the welded seam pipe is wrapped around another form. As the heat, stress and other extraneous variables are added to the forming process, these are never as round as seamless steel pipe. The seamless steel pipe needs a continuous extrusion of the alloy, so that there is a round cross section that you can count on, which is helpful for installing pipes or adding fittings.

The third benefit of the seamless steel pipe is the strength under loads. Even though the seamless steel pipe is more expensive than other forms of steel pipe, it is more reliable, for its greater strength under loading. Different from empty pipe which must support its own weight, the pipe filled with material or under load can support that weight. The seamless steel pipe will not worry about the phenomenon such as pipe failures and leaks like in welded steel pipe.

These three benefits of seamless steel pipe make it suitable for more applications, for example, ship building, pipelines, oil rigs, oil field equipment, pressure vessels, machinery parts, offshore rigs and so on.
