Applicant Field
- The three grades of ASTM A106 (A, B, C) are differentiated based on strength and have different applications, with Grade B being the most commonly used grade in foreign trade.
| GRADE | Field |
| A | Mainly exported to small factories and civilian facility projects in developing countries, serving as low-cost general-purpose pipes, supporting low-voltage equipment. |
| B | The main pipe material for global oil refining projects and power plant construction projects, with exports accounting for more than 80% of the ASTM A106 series, is often specified by customers as the standard pipe for medium- to high-temperature and high-pressure fluid transportation. |
| C | Mainly supplied to high-end petrochemical projects and large-scale power plant EPC projects, The clients are mostly large engineering companies from Europe, the United States, the Middle East, and other regions. |
Core Advantage of ASTM A106 SMLS Pipe
- Excellent high-temperature stability: Specifically designed for high-temperature conditions, ASME SA106 / ASTM A106 SMLS maintains stable tensile yield strength and creep resistance in high-temperature environments, far superior to ordinary structural seamless pipes.
- Uniform mechanical properties: ASME SA106 / ASTM A106 SMLS Using a seamless rolling process, the pipe has no weld defects, uniform wall thickness, and can withstand repeated impacts from high-pressure fluids.
- Good machinability: for ASME SA106 / ASTM A106 SMLSThe composition of carbon-manganese steel is reasonably designed, offering excellent cold working, hot working, and welding performance, suitable for the installation of complex piping systems.
