Dear Sudheer

 

it depends on the purpose of the piping and design life

 

for Above ground piping it is generally

 

Primer:                 Zinc Silicate

Intemediate Coat:  MIO

Final Coat:            PU

 

For Under ground piping

 

Primer:                               Epoxy based primer

Intermediate and Final Coat: CTE, FBE, PE

 

the above paint systems are used primarily in Petoleum Pipelines where the design life is 30yrs or more

Pramod,

 

One of criteria to decide the painting schedule is service temperature and location of the plant.
