It would be vain if we adopt the wrong or unsuitable steel pipe for our engineering project. So even for seamless steel pipe with carbon and alloy materials, we should figure out the detailed categories with different ingredient among their production process.

If we image the steel pipes in the web and we would see lots of points in this web with different categories. Here is the chart for the comparison of carbon and alloy pipe line for customers. From the chart, we can find out that there are ten categories for carbon steel with different standards for different work situation. Thus, you would know how to choose your tubes for high or low pressure service, seamless or welded one is also clear in this chart. Of course, for four kinds of corrosion resistant alloy steel tubes, you would know how to choose too.
