It could be caused by a hundered different things. You are going to have to be more specific about all the details of your specific application before anyone can make an educated guess as to what your problem is.

Questions such as:
1) What's the operating condition
2) Apart from wet gas, what's running inside the pipeline (e.g. HP steam, any contaminations'?
3) Where there a change of duty prior to flooding the pipeline with wet gas?
4) What's in the wet gas?
5) Where's the pipeline running from? (e.f. refining units, hydro desulphidation unit etc. etc.)
6) Any history of failure in regards to the pipeline?
