What Is AIS Pipe?

AIS pipe refers to steel pipe products that are fully manufactured in the United States and meet the requirements outlined in the American Iron and Steel (AIS) provisions established by the Environmental Protection Agency (EPA). These provisions apply to projects funded by federal and state revolving loan programs, including:

Drinking Water State Revolving Fund (DWSRF)
Clean Water State Revolving Fund (CWSRF)

Under AIS regulations, eligible pipe products must be produced using domestic steel and manufactured entirely within the U.S., including all melting, forming, and finishing processes.

Crestwood Tubulars works with certified domestic manufacturers to ensure every piece of AIS pipe we supply is fully compliant and ready for submittal.

Applications for AIS-Compliant Pipe

AIS-certified steel pipe is used in a wide range of publicly funded infrastructure projects, particularly in the water and wastewater sectors. Common applications include:

Water Infrastructure

Water mains and service lines
Transmission and distribution systems
Elevated water storage tanks and reservoirs

Sewer and Wastewater

Gravity sewer lines and force mains
Stormwater drainage systems
Treatment plant piping

Utility and Public Works

Casing pipe for utility crossings
Road bore casings for water and sewer
Conduit pipe for electrical or telecommunications systems

Choosing AIS pipe helps ensure your project qualifies for federal funding and avoids costly delays due to non-compliance.
