Hi:

I have some troubles defining mainline block valves, ASME B31.4 refers to "major river", but how to define it, how depth?, width? flow rate?. The pipeline has 27 km, and cross at least 4 rivers and 15 marshes and swamps.

How many mainline block valves I have to put on it?

Best Regards,

Luis Felipe
