Carbon Pipe and Tube

Carbon steel is more commonly used than any other metal, and has long been admired for its versatility and low cost.

U.S. Steel Pipe stocks a complete selection of carbon steel pipe and steel tubing in an extraordinary range of grades and specifications. Seamless steel pipe and tubing is stocked in outer diameters (OD’s) through 36”, ERW (Electric Resistance Welded) pipe, including rolled and welded pipe and spiral weld pipe, is stocked in OD’s through 60”.

As a specialist in schedule and non-schedule heavy wall pipe and tubing, U.S. Steel Pipe inventories multiple specifications, including API 5L (X-grades), ASTM (A106 B/C, A53, A519, A513 Type 5 DOM), and ASME specifications.

A-106 Grade B/C

This American Society for Testing and Materials (ASTM) specification covers seamless steel pipe for high temperature service in the size range of 1/8” NPS to 48” NPS. U.S. Steel Pipe is a stocking distributor of carbon steel pipes to this specification in sizes from ¼” NPS to 36” NPS, specializing in heavy wall pipe. Seamless steel pipe ordered under this specification is suitable for bending, flanging, forming, and welding. Key applications for A106 and SA106 include refineries, power plants, boilers, ship building, and other specialized applications. Pressure pipe applications also include heat exchangers, condenser and boilers.

SA-106 Grade B/C

This is an ASME specification covering manufacture and installation of pressure piping and is tightly regulated by the ASME (American Society of Mechanical Engineers) Boiler and Pressure Vessel Code. Pressure piping is generally pipe that must carry pressures greater than 10 to 25 atmospheres, although definitions vary. To ensure safe operation of the system, the manufacture, storage, welding, testing, etc. of pressure piping must meet stringent quality standards.
