Carbon Steel Pipe

SEAMLESS CARBON PIPE

The complex chemical and physical properties of the various grades of carbon steel pipe allow for a broad range of service usage. American Piping Products has the right grade, size and price to meet your requirements, including A/SA-106 Grade B/C and API 5L X- 42 thru X -70. A/SA-106 Grades B & C are utilized for services ranging from structural supports to steam drum headers with temperature ranges up to 800°F, while API 5L X Grades 42 thru 70 are utilized for the water and petroleum industry to transport liquids or as platforms on off-shore rigs.

Standard Carbon Steel Pipe Specifications & Grades

A/SA-106 – Grades B & C

A106 PIPE

ASTM A106 Seamless Pressure Pipe (also known as ASME SA106 pipe) is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels.

American Piping Products stocks a full range of A106 pipe (SA106 Pipe) in:

Grades B and C

NPS ¼” to 30” diameter

Schedules 10 through 160, STD, XH and XXH

Schedules 20 through XXH

Wall Thickness beyond XXH, including:
– Up to 4” wall in 20” through 24” OD
– Up to 3” wall in 10” through 18” OD
– Up to 2” wall in 4” through 8” OD

A/SA-53 Seamless – Grade B

A53 PIPE

ASTM A53 pipe (also referred to as ASME SA53 pipe) is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines. It is suitable for welding and for forming operations involving coiling, bending, and flanging, subject to certain qualifications.

Scope

ASTM A53 pipe covers Seamless and Welded, Black and Hot-Dipped Galvanized nominal (average) wall pipe for coiling, bending, flanging and other special purposes and are suitable for welding. Continuous-Welded pipe is not intended for flanging. Purpose for which pipe is intended should be stated on order.

Materials and Manufacture

The steel for both seamless and welded pipe shall be made by one or more of the following processes: open-hearth, electric furnace, or basic-oxygen. The weld seam of electric-resistance welded pipe in Grade B shall be heat treated after welding.
