BI Pipe S80

• General Info

  BI Pipe S80 (Black Iron Pipe Schedule 80) refers to a Black Iron Pipe (commonly made from carbon steel) with a Schedule 80 thickness. This designation means that the pipe has a thicker wall compared to Schedule 40 or Schedule 20 pipes, providing increased strength and pressure resistance. Black iron pipe (BI pipe) is generally used for gas, water, and other fluid transportation, where higher strength and pressure ratings are required, but it lacks the galvanization of GI pipe, making it more prone to corrosion when exposed to moisture.

• Specification

  Wall Thickness
  The wall thickness of Schedule 80 (S80) pipes is significantly thicker than Schedule 40 and Schedule 20 pipes, allowing it to handle higher pressures. The wall thickness varies depending on the Nominal Pipe Size (NPS)
