API 5L B Carbon Steel Pipe Tube refers to a type of carbon steel pipeline that meets the specifications of the American Petroleum Institute (API) standard API 5L. The "B" designation in API 5L B indicates the lowest yield strength level among the grades specified in the standard.
API 5L B Carbon Steel Pipe Tube is made from carbon steel, which is a type of steel that contains a relatively low amount of carbon, typically less than 2.1% by weight. This low carbon content provides good weldability and formability, making it suitable for pipeline applications.
These pipes are commonly used in low-pressure pipeline systems, such as those used for water supply, irrigation, and other non-critical fluid transport applications. They are not typically used in high-pressure or high-temperature environments where higher-grade API 5L pipes, such as X42, X52, X56, or X60, would be required.
