Seamless Line Pipe

Line pipe is a tube made of high strength carbon steel. It is typically manufactured according to the API 5L metallurgical specification developed by the American Petroleum Institute (API). The raw material can be either seamless or welded carbon steel or stainless steel piping. This product can be used to build pipelines that transport a variety of resources including natural gas, oil, petroleum, and water. API 5L line pipe is available in various diameters ranging from two inches to 48 inches. Its size and diameter required for a pipeline vary according to the amount of gas or liquid that it intended to carry and the pressures it must withstand.
