I have several chlorine projects going on and a couple of them are being installed by the same contractor, one of the best contractors in the chemical industry (I wish I could name them by my CA prevents me from listing them as a client or supporter!). They used the pandemic to get everything installed and now we are ready for our post-construction and Pre-PSSR activities, which is when we do our integrity testing on our Cl2 Class I “Gas ONLY” piping. The “gas only” piping is CPVC piping, using “solvent welded sockets”, a very common means to join CPVC and PVC piping. Of course, Pamphlet 6 requires the piping to be installed per ASME B31.3 and this is where things get squirrelly with our CPVC piping…
