With the development of oil weather or other goods transmission environment, we should know that remote areas, oceans, and cold regions are also necessary to be considered even when we use seamless steel pipe for transport tools.

Today, we would have a view for general comparison for API seamless steel pipe. There are three types of this category. They are:

API 5L: Line pipe for pipeline transportation systems;

API 5CT: Tubing and casing for wells;

API 5DP: Drill Pipe for well drilling.

Different grades would cause different effect during the transmission. Under this situation, it is necessary to figure out what’s your engineering project before determination for the API pipe’s choosing.
