ASTM Pipes are a category of steel pipes manufactured in accordance with ASTM International standards. Unlike the API 5L standard, which focuses on pipes for the oil and gas industry, ASTM encompasses a wide range of standards tailored for various applications.
This is a very broad product category, including black steel pipes, welded steel pipes, seamless steel pipes, and heat-resistant pipes.

Common ASTM Standards
– ASTM A53: Welded or seamless carbon steel pipe for industrial piping and structural applications
– ASTM A106: Seamless carbon steel pipe for high-temperature service
– ASTM A333: Steel pipe for low-temperature service
– ASTM A335: Alloy steel pipe for high-temperature service
– ASTM A312: Stainless steel pipe
– ASTM A252: Steel pipe for use as foundation piles (pipe piles)
– ASTM A500: Structural steel tubing (round, square, and rectangular)

Key Specifications
– OD: Outside Diameter (inch or mm)
– WT: Wall Thickness (inch or mm)
– Schedule (SCH): Wall thickness designation.
– Grade: Steel grade.
– Manufacturing Process: Seamless or Welded.
– Length: Length.
– End Type: Plain End, Beveled End, or Threaded End.

Applications
– Chemical plants.
– Thermal power plants.
– Oil refineries.
– Steam systems.
– Water supply systems.
– Construction and structural projects.
