ASTM A106 - Standard Specification for Seamless Carbon Steel Pipe for High-Temperature Service
ASTM A106 Seamless steel pipe (also known as ASME SA106 pipes) is an American standard steel pipe.
This specification covers carbon steel pipe for high-temperature service. These pipes are suitable for welding, bending, flanging, and similar forming operations. Mechanical testing of the specimens shall include tensile, bending, flattening, hydrostatic and nondestructive electric tests. Specimens undergoing bending tests shall consist of sections cut from a pipe. For flattening tests, the specimens shall be smooth on the ends and burr-free, except when made on crop ends. All tests shall be performed in room temperature. If any test specimen shows flaws it can be discarded and substituted for another test specimen. Before testing, if a specimen has scribe scratches, a retest shall be allowed. A retest shall also be allowed if a specimen breaks in an inside or outside surface flaw.
For ASTM A106 seamless steel pipe could transport fluids or gasses at high temperature and pressure levels, with 3 grades A, B, C, most common used ASTM A106 Grade B is widely used in the projects of oil and gas refineries, power plants, petrochemical plants, boilers.
About ASTM A106 Grade B:
ASTM A106 Grade B Pipe (also known as ASME SA106 GR.B pipes) is used in power plants, boilers, petrochemical plants, oil and gas refineries, and ships where the piping must transport hot or cold liquids and gases under high pressures and temperatures. A106 GR. B Carbon Steel Seamless Pipes, A106 Gr B Sch 40 pipe, ASTM A106 Grade B Pipe Suppliers is available in various weights, sizes, and black and galvanized grades both seamless and electric welded. ASTM A106 Grade B Pipe sizes, less than 2" is it normally delivered as a cold drawn product. 2" and up are usually hot finished.
About ASTM A106 Grade C:
ASTM A106 Grade C Pipe (also known as ASME SA106 GR.C pipes) is a carbon-manganese steel pipe for high-temperature large-diameter boilers and superheaters. Its chemical composition is simple and similar to 20G carbon steel, but its carbon and manganese content is higher, so its yield strength is about 12% higher than that of 20G, and its plasticity and toughness are not bad. The steel has a simple production process and good cold and hot workability. Using it to replace 20G headers (economizer, water wall, low-temperature superheater and reheater header) can reduce the wall thickness by about 10%, which can save material costs, reduce welding workload, and improve headers The stress difference at start-up.
