Tubes for thermal applications – line pipe

Description and supply details

API 5L tubes

Carbon steel tubes in the API 5L range are the most widely used tubes for transporting fluids or gases (water, oil or gas).
The governing standard (API 5L) refers to the guidelines issued by the American Petroleum Institute and ensures the technical, chemical, physical and mechanical standards of the tube.

API 5L tubes can be manufactured seamless or welded; the standard makes no distinction between the two manufacturing methods.
Tubes are supplied with a production certificate (generally 3.1 certificates), providing documentation and traceability for the procured material.
These tubes are specifically intended for pipelines, conduits, pressure applications or petrochemical plants.
