A106 GR B Pipe VS A179 Pipe
A106 GR B pipe and A179 pipe are two common seamless steel pipes, which are widely used in different industrial fields. Here are their main differences:
Features | A106 GR B pipe | A179 pipe |
Material type | Carbon steel | Low carbon steel |
Standards | ASTM A106 | ASTM A179 |
Application environment | High temperature and high pressure | Low temperature heat exchangers, |
Tensile strength | ≥415 MPa | 325 - 485 MPa |
Yield strength | ≥240 MPa | ≥180 MPa |
Ductility | Medium | High |
Thermal conductivity | General | Excellent |
Wall thickness | Thicker, suitable for high pressure | Thin, suitable for environments |
Application areas | Petroleum, natural gas, chemical, | Heat exchanger pipes, boilers, |
1.Material and strength: A106 GR B pipe has high tensile strength and yield strength, suitable for high temperature and high pressure environment; A179 pipe has low carbon, good ductility, excellent thermal conductivity, and is suitable for low temperature equipment.
2. Application scenarios: A106 GR B pipe is often used in high temperature and high pressure environments such as petroleum, natural gas and chemical industry; A179 pipe is mainly used for heat exchangers, condensers and other equipment that require thin walls and high precision.
