The information here is summarized from ASTM Standards and API Specification 5L. Please see the specific standards for more information.

API 5L specification covers seamless and welded steel line pipe. It includes standard-weight and extra-strong threaded line pipe and standard-weight plain-end, regular-weight plain-end, special plain-end, extra-strong plain-end,  as as well as bell and spigot and through-the-flow line(TFL) pipe.
The purpose of this specification is to provide standards for pipe suitable for use in conveying gas, water, and oil in both the oil and natural gas industries.
The American Petroleum Institute specification API 5L covers seamless and welded steel line pipe. This is steel pipe for pipeline transportation systems in the petroleum and natural gas industries. Size range is limited only by manufacturer's capabilities.

Specifications for API 5L adhere to the International Organization for Standardization ISO 3183, which standardizes pipeline transportation systems within the materials, equipment and offshore structures for petroleum, petrochemical, and natural gas industries.
