API 5L Gr.B Caton Steel Pipe Testing: Transverse or Longitudinal Tension Test and Flattening Test, Hardness Test, or Bend Test
For material heat treated in a batch-type furnace, tests shall be made on 5% of the pipe from each treated lot. For small lots, at least one pipe shall be tested. For material heat treated by the continuous process, tests shall be made on a sufficient number of pipes to constitute 5% of the lot, but in no case less than 2 pipe.
Hydrostatic Test:
Impact Test: One notched bar impact test, consisting of breaking three specimens shall be made from each heat represented in a heat-treatment load on specimens taken from the finished pipe.
API 5L Gr.B Carbon Steel Black Pipe Application:
Buildings, infrastructure, tools, ships, automobiles, machines and appliances are all made from steel. Steel is frequently used because it is durable and safe. Building materials underground may be susceptible to rotting and pests. Since Welded Line Pipe API 5L Gr.B Black Pipe steel is non-combustible and makes it harder for fire to spread, it is good to use when building homes. API 5L Gr.B Carbon Steel Black Pipe is highly resistant to shock and vibration. Welded Line Pipe API 5L Gr.B Black Pipe is Environmentally Friendly as well Cost-Effective.
