Comparision Between SA214 Tube Vs SA179 Tube

SA-214 and SA-179 are both types of carbon steel tubes that are commonly used in heat exchangers and boilers, but they have different characteristics and properties.

SA-214 tubes are medium-carbon steel tubes with a minimum wall thickness of 0.028 inches. They are heat-treated after welding to improve their toughness and ductility, and they are often used in high-pressure applications where their resistance to stress corrosion cracking is important.

SA-179 tubes, on the other hand, are low-carbon steel tubes with a minimum wall thickness of 0.035 inches. They are generally used in low-pressure applications, such as in condensers, evaporators, and heat exchangers. They are known for their excellent heat transfer properties and their ability to resist corrosion.

Introduce SA-214 Tubes:

SA-214 is a medium-carbon steel material with a composition of carbon, manganese, phosphorus, sulfur, and silicon. These tubes are generally used in high-pressure applications such as steam boilers and pressure vessels, where their resistance to stress corrosion cracking and high toughness are important. SA-214 tubes are heat-treated after welding to improve their toughness and ductility. This process is known as normalization and involves heating the tubes to a temperature of around 1650°F (899°C) and then cooling them slowly in air.

SA-214 tubes have a minimum yield strength of 37,000 psi (255 MPa) and a minimum tensile strength of 70,000 psi (483 MPa). They also have a minimum elongation of 30% and a minimum hardness of 89 HRB.

Introduce SA-179 Tubes:

SA-179 is a low-carbon steel material with a composition of carbon, manganese, phosphorus, and sulfur. These tubes are generally used in low-pressure applications such as condensers, evaporators, and heat exchangers, where their excellent heat transfer properties and corrosion resistance are important. SA-179 tubes are known for their high thermal conductivity, which makes them ideal for transferring heat between fluids.

SA-179 tubes have a minimum yield strength of 47,000 psi (325 MPa) and a minimum tensile strength of 70,000 psi (483 MPa). They also have a minimum elongation of 35% and a minimum hardness of 72 HRB.

In summary, SA-214 tubes are made of medium-carbon steel and are used in high-pressure applications where resistance to stress corrosion cracking is important, while SA-179 tubes are made of low-carbon steel and are used in low-pressure applications where excellent heat transfer properties and corrosion resistance are critical. Both types of tubes have different mechanical properties and are suited to different applications, so its important to select the appropriate type for your specific needs.SA-214 tubes are generally used in high-pressure applications where resistance to stress corrosion cracking is important, while SA-179 tubes are more commonly used in low-pressure applications where excellent heat transfer properties and corrosion resistance are critical.
