Differences between SA213 and SA312
Thread Content
The difference between SA213 and SA312: SA213 is used for boiler tubes, while SA312 is used for pipes. For example: carbon steel, alloy steel, stainless steels SA213--304, SA312-304. Are their chemical and mechanical properties the same? Are the testing requirements identical? Can they be used as substitutes for one another?
213 refers to a tube, while 312 refers to a pipe. There are numerous publications discussing the differences between tubes and pipes: \"In the context of boilers and pressure vessels, tubes are primarily used for heat conduction between the inside and outside as well as for heat exchange purposes, whereas pipes are mainly designed to transport pressurized fluids from one place to another. Pipes of this type usually come equipped with various accessories such as tees, elbows, and valves.\" ” SA-213 is a special steel tube for heat exchange tubes, while SA-312 is a steel tube for transporting fluids. In my opinion, the two are different and cannot replace each other. - This article is from ASME Made in China; the original address is: http://www.asimi8.com/thread-736-1-1.html
