underground steel piping - Compacting of soil using seawater
underground steel piping - Compacting of soil using seawater
(OP)
Dear guys. I would like to know if someone has any idea (if there is any specification or code) that mentions about the use of sea water for compacting soil above underground Steel pipelines. Although this steel pipeline will have a PE coating, I think that high percentage of chlorides that sea water contains will attack directly the weak zones of touch-up. any advice or opinion?
Thanks in advance!!
Thanks in advance!!

as far as re-vegetation is concerned, topsoil should be stripped and then replaced with minimal compaction. I would not see a need to add water to compact topsoil.

However, the Welded Steel Pipe Design Manual does not mention sea water.

Cathodic protection would also normally be provided to the pipe to counter the affects of any undetected pinholes or those that might develop in future.
NACE SP0169 covers the design of cathodic protection systems for pipelines.
