I now work in the design of power plant condenser - 60 Wanshui condenser. Now there are doubts on the condenser cooling pipe problem (water from the Yangtze River water, sediment, seawater intrusion, but there are problems) hope to teach master (the hope can make the economic efficiency and the performance of the condenser to achieve comprehensive optimization)
Anti seawater corrosion performance of dual phase steel pipe, 316L, titanium and so on, in which the titanium tube is the best, the annual corrosion rate of about 0.008mm/a, but the price should be the highest, ha ha.It is possible to consider the use of composite tubes (titanium tubes and carbon steel tubes, titanium tubes and seawater medium contact, carbon steel can not touch the sea water), not only to ensure corrosion resistance and strength requirements, but also greatly reduce material costs.
Mainly contact with sea water, you can choose to use stainless steel 316L, of course, titanium can also beAnd other optional design of 20 carbon steel and so on
I suggest you use Navy brass tubes.
