ASTM A106
/glossary/astm-a106American standard for seamless carbon steel pipe for high-temperature service.
In detail
ASTM A106/A106M specifies seamless carbon steel pipe for high-temperature service in NPS 1/8 to NPS 48. It covers three grades (A, B, and C) with increasing carbon content and tensile strength. The standard requires heat treatment, NDE testing, and strict dimensional tolerances, making it the reference specification for high-pressure steam, boiler feedwater, and process piping in petrochemical and power generation industries.
Where you'll meet this in procurement
You will meet ASTM A106 when a buyer, consultant, or mill quote names a governing specification. Confirm which revision applies, what tests the standard requires, and whether the grade on the MTC actually matches the ASTM A106 call-out on the RFQ before you lock commercial terms.
