API 5L Grade B Carbon steel pipe
Classification :
PRODUCT DETAILS
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. API 5L is suitable for conveying gas, water, and oil. 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.
The technical committee authoring the standards recognized that there are two basic Product Specifications Levels (PSL) of technical requirements and therefore developed PSL 1 and PSL 2. PSL 1 is a standard quality for line pipe where PSL 2 contains additional chemical, mechanical properties, and testing requirements.
Grades covered by this specification are A25 ,A ,B (and the following “X” Grades), X42, X46, X52, X56, X60, X65, X70, X80. The two digit number following the “X” indicates the Minimum Yield Strength (in 000’s psi) of pipe produced to this grade.

Application Area
Circular/square pipes made of carbon steel have various applications in many industries, typically requiring their strength, durability, and versatility. Some common applications include:
Mainly used for structural support, frames, columns, beams, and brackets in construction, bridge, and infrastructure projects.
It is used for manufacturing equipment and mechanical frames, conveyor systems, material handling equipment, and structural components for industrial applications.
Due to its weldability and formability, square pipes made of carbon steel are popular in metal manufacturing for the production of frames, racks, shelving units, and platforms.
In some industrial applications, carbon steel square tubes can be used as part of pipeline systems for transporting fluids or gases, especially in low-pressure applications.
