Hi guys,

Does any of you guys have information on API 5L (American Petroleum 
Institute) standars for water pipes? 

I need to learm more on the standards since we are using steel pipes 
of API 5L standards for the penstock line of one of our hydro 
projects.

Any information on the above standards or any link where information 
can be downloaded for free is highly appreciated.

Best regards

Sudarshan
