Our shady (at best) Turkish contractor who is building our wastewater treatment plant was supposed to use Schedule 80 or glavanized steel for the air diffuser piping. Since you can flex the pipe just by squeezing it, I'm going to go out on a limb here and say they used a much crappier grade of PVC. Just for the record, this was all put in long before I got here and the PVC in question were below the waterline (they filled the plant with clean water to test the equipment) so we couldn't even see it until they just drained the tanks to fix some cracks in the concrete. What kind of second rate PVC did they install?
