coating for drinking water pipes

Hello all,

I am designing a buried pipe system for drinking proyect with carbon steel pipes. Could anyone to help me to select the correct coating (internally and externally)? Do you recomend me any good bibliography or design guide?

Thanks in advance.

RE: coating for drinking water pipes

if in the US, suggest you follow AWWA standards or 10 state standards

Thank you cvg.
Does anyone ff is it in Europe??

RE: coating for drinking water pipes

Except for maybe a private trailer park, you probably would not be able to find a potable water installation using steel pipe. The reason for this is that the service life for carbon steel piping will not be acceptable for most users. Most potable water applications use either ductile iron or PVC pipe. Piping within buildings may be galvanized steel pipe.

The European practices as well as the world practices are similar to the United States practices. However, the water usages are typically much lower in the rest of the world.

Some of the countries in Europe have their own standards. The UK and Russian Federation for example have their own standards.

RE: coating for drinking water pipes

majority of large public water transmission and distribution systems in california are steel cml&c pipe, very widely used outside of trailer parks

RE: coating for drinking water pipes

Many systems in the western United States use steel pipe for large transmission mains. As long as they are properly coated and cathodic protection is used and maintained, they should have a service life equal to other materials. A system I recently worked for had over 200 miles of steel pipe, 18" to 42".

RE: coating for drinking water pipes

Don't believe that the poster is talking about transmission mains. Perhaps he can add some details.
