undergound air pipeline coating
undergound air pipeline coating
(OP)
Dear experts,
one of our underground utility air line (SA 53) was leaked & the patch replacement was done. now the earlier line had Ca2SiO4 wrapped with some black plastic on it. but as per specs for underground piping, it says
primer PE; wrapping PE & mastic coating bitumastic 50
which one can be followed?

RE: undergound air pipeline coating
I would have the failure examined from the point of view as to whether Cathodic Protection might be of value. A good across the board Cathodic Protection Company is Corrpro.
You also may want to look over the materials offered by someone like Denso.
