I echo Mr. Bernhard Rijpkema's idea of this being PP. I have worked on polypropylene lined fitting failures that developed due to severe temperature cycles. The idea would be easy to check: if you place a small section of the failed liner in distilled water, it should float (density <1). Instead, PTFE and PFA sink very quickly (density >2).

If it is PTFE (this can be confirmed by analytical tests) then one possibility is an extremely poor sintering. I did come across a case of poorly sintered lined pipe spool which looked like this. Also the lining thickness looks to be too high. I can't be sure from the picture. ------------------------------ Pradip Khaladkar Fellow and Associate Director MTI DE 302 245 8426 ------------------------------
