What's the difference between the API 5L X80 and the A179?
API 5L X80 and A179 are two different steel pipe standards, mainly in the following areas:
Application areas:
API 5L X80 is a strength grade in the API specification for pipeline steel pipe, which is mainly used in the oil and gas industry for gas transmission lines.
A179, on the other hand, is mainly used in the manufacture of heat exchangers, especially cooling tubes.
Strength and specifications:
X80 represents a minimum yield strength of 80,000 psi (about 552 MPa) for steel pipe, a higher strength grade for pipelines requiring higher pressure and durability.
The A179 standard has a yield strength of ≥180 mpa and a tensile strength of ≥325 mpa to withstand high temperatures for use in boiler tubes.
Manufacturing Process:
Manufacturing of API 5L X80 pipe may involve specific processes, such as controlled rolling and thermo-mechanical treatments, to ensure the strength and toughness of the pipe.
Manufacturing of A179 pipe may focus more on thermal conductivity and corrosion resistance, and therefore may differ from X80 in material selection and manufacturing processes.
