After a pumping is completed through this 3inch diameter line, which has uni-directional segments as long as 300 ft, then 40 to 70 psig nitrogen is turned on through a 3/4 inch ball valve. A slug flow situation follows that causes the line to rock & jump.

The line has one expansion loop & is anchored to a few points that tee off of the main line.

The line is on hangers and shoes to accomodate for thermal growth. Temperature can vary 150F on this 316 stainless line.

Looking for methods to safely dampen the pulses.

The line is filled with product that must be blown out to the destination tank.

Thanks[*]
