Specification matches application for steel pipe

Different specification would lead to the various characters for steel pipe. And it would finally lead to the different application for the steel pipe. Thus we would call it by seamless steel pipe or ERW steel pipe and other steel pipes by the name we made it before the production.

Here is the chart of part of specification for different steel pipes matching the relative application in our daily life. From the picture, we can figure out that whether these steel pipes used for line pipe, casing tubing, or ordinary piping, or oil and gas transmission, we should get the character test first. In order to have a good service for human beings, specification must follow the demand of application.
