Savoy Piping Inc. supplies ASTM A106 Grade B (ASME SA106 Gr B) seamless carbon steel pipe — the workhorse grade for high-temperature pressure piping in refineries, power plants, petrochemical and process plants.
Order by OD/wall (or schedule), ends, length and documentation. Hot-finished is typical from NPS 2 upward; cold-drawn sizes need heat treatment after the final draw pass per the specification.
Typical strength: tensile min 60 ksi (415 MPa), yield min 35 ksi (240 MPa). Carbon max 0.30%, manganese 0.29–1.06%, silicon min 0.10%.
Related: A106 Grade C, A53 Grade B, A333 Grade 6, Carbon Steel Seamless Hub.
ASTM A106 / ASME SA106 covers seamless carbon steel pipe for high-temperature service. Grade B is the most widely stocked and specified grade for steam, process fluid and utility lines where elevated temperature strength and weldability matter.
A106 is a seamless-only specification — do not confuse it with welded pipe standards.
Also see: Carbon steel seamless hub · API 5L hub · CS buttweld.
Confirm design temperature and pressure against the governing code (ASME B31.1 / B31.3, etc.), then lock schedule or wall, ends (PE/BE), delivery condition and test package (hydro, NDE, IBR, NACE if sour). If the datasheet asks for higher strength, review Grade C before substituting.
A106 = seamless high-temp service. A53 = general purpose seamless/welded. A333 = low-temperature / notch-toughness service (impact tested). Match the standard to the design temperature, not just the grade letter.

Standard Specification for Seamless Carbon Steel Pipe for High-Temperature Service
ASTM A106 pipe (also covered in ASME specifications as S/A 106) is the standard specification for seamless Carbon Steel Pipes for high-temperature service. Most common uses are in refineries and plants when gasses or fluids are transported at High Temperature and pressures. Savoy Piping Inc. supplies A106 / SA 106 pipe and stocks a full range of grades B/C in a size rage of NPS 1/8" to NPS 48", with nominal (average) wall thickness as given in ANSI B36.10. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification*.

ASTM A106 Grade B is seamless carbon steel pipe for high-temperature service — process lines, steam, refineries, power plants and similar pressure piping where hot fluids or gases are transported.
Grade B is the most common commercial grade (min tensile 60 ksi / 415 MPa, yield 35 ksi / 240 MPa). Grade C is stronger (70 ksi / 485 MPa tensile, 40 ksi / 275 MPa yield) when the design needs higher strength. Do not substitute without checking the PO and design code.
No. A106 covers seamless pipe for high-temperature service. A53 covers seamless and welded black/galvanized pipe for general use. Many packages dual-certify A106B/A53B when chemistry and testing allow — confirm on the MTC.
Yes. We supply ASTM A106 / ASME SA106 Grade B seamless pipe with EN 10204 3.1 or 3.2 certificates, and can support IBR, NACE / sour-service and third-party inspection when specified.
We supply this product for domestic and export projects with mill test certificates (EN 10204 3.1 standard; 3.2 / TPI on request). Include destination, preferred Incoterms and any inspection body on the RFQ.
