Does anyone have experience such PTFE failure with in one year service period.---------- It contains 60- 70%H2SO4 and has about temperature cycles from 15 to 30c. with moisture and some traces of cl2 from chlorine dryer column.
Hello, Mr. Saddiq,
I have worked quite a bit on PTFE lined equipment though mainly for HCL service. Is the PTFE liner as "yellowed" as it appears to be in the photo? Also, do you know the age of the fitting? Typically, I expect the liner to be whiter than the image shows. The color gives me the impression of either permeation or the liner perhaps being made of a fluorocarbon different than PTFE (PFA?) Typically, for these failures, the following examinations give a great deal of information:
I would also discuss the large temperature fluctuations with the supplier. Most liners do not like thermal shocks.
