Craig, I don't think there is any problem with roll grooving schedule 40 pipe. Am I wrong? We do it all the time.

Did he buy it already grooved or groove it himself? And if it failed the pressure test, why did it all fall down, improperly supported? I don't see where the "it was thinner at the grooved ends" would automatically mean failure. Unless it improperly grooved, like someone trying to roll groove sch. 40 in stead of cutting it. Sounds kinda funny................ Craig L.

This was forwarded to me from another AHJ. Have any contractors out there have any knowledge of this? Just a quick note that today a sprinkler fitter had over 120 feet of six inch galvanized pipe fail during a hydro test today. In fact, it would be fair to say that it violently failed today. After examination by the sprinkler company and the fire department, we determined that there were two suppliers of the pipe. a majority of it made in Turkey and these sections that failed was made in China. The entire pipe is properly stamped to meet the standards, through just by feel only it was evident that the product made in China was substantially thinner in all of the grooved ends that failed. The sprinkler fitter is pulling the entire China produced pipe out and replacing it. So, as a simple FYI, watch out for the grooved galvanized pipe that is clearly labeled as Made in China. One construction worker was injured and it scared the (blank) out of a bunch of other workers as sixty feet of this pipe came crashing down.
