You know businesses are cutting costs when I get this question. But it is a good question as we have come across “reclaimed piping” being used in a lesser-degree hazard (e.g., flammable gas to flammable liquid) process. I personally never experienced this practice in my time in industry, but it has become more popular as businesses look for more ways to reduce costs. So is there a RAGAGEP that covers this practice? Absolutely and here is what it says…

ASME B31.3 PART 7 MATERIALS A323 GENERAL REQUIREMENTS A323.1.4 Reclaimed Materials Reclaimed piping components may be used, provided they are PROPERLY IDENTIFIED as conforming to a listed or published specification (see para. 323.1.1) and otherwise meet the requirements of this Code. The user shall verify that components are suitable for the intended service. Sufficient cleaning, EXAMINATION, AND TESTING shall be performed to determine the minimum available wall thickness and freedom from any of the following to an extent that would be unacceptable in the intended (a) imperfections (b) reduction of mechanical properties, or (c) absorption of deleterious substances |
So we can see, re-using piping is acceptable, but will REQUIRE a “qualification process” to ensure it is suitable via examination and testing.
