Wrapping vs Coating for Underground Piping
Wrapping vs Coating for Underground Piping
(OP)
Hi Guys,
Anyone got something to share on the protection of the underground (UG) piping?
For our project, based on the specification, the UG piping (firewater line and oily water sewer line) needs to be coated and wrapped. We had a meeting this morning & somebody mentioned that it is either coated or wrapped.
Just to check, what is the common practice in oil & gas industry? Is it adequate to just coated without wrapping with tape?
If we need to wrap, is it normal to do it at site or at factory? Do we have machine pipe wrapping? or is it practical/economical to do it manually?
Thanks

RE: Wrapping vs Coating for Underground Piping
After further investigation, now I realize that there are 2 methods of UG pipe protection
1) TAPE WRAPPING - manual vs machine
2) COATING like Yellow Jacket
Prior to above, still need to do surface preparation of the pipe:
1) Blasting
2) Primer - coating (1st coat & 2nd coat)
For such a relatively short pipe (2-4km), is it economic to have COATING? I was informed that for very long natural gas pipeline, normally it is COATED...
Thanks
