A company has a lot of unidentified carbon steel piping which they would like to use for ASME B31.3, General Service conditions. Is it acceptable to do PMI with a machine such as the SpectroTest Spark Analyzer, determine the chemical composition of the piping and then certify it acceptable for ASME Code use? Must samples also be cut out for tensile and yeild strength tests?

What you can do is remove a sample, send it to a test lab and have a full chemical analysis performed along with hardness testing to type the material.

The only requirements for hardness values I can find are for the maximum hardness values for welded connections after heat treatment (B31.3, Table 331.1.1). And these maximum values are for alloy steels.
