10/7/2017 · For cyclohexylamine about 4 to 5 ppm are needed in steam to get one ppm dissolved in the condensate. DEAE is more efficient, having a steam/condensate distribution ratio of about 2. Morpholine has the lowest distribution ratio of about 0.4. This indicates the highest tendency to dissolve in first-formed condensate.
This valve is obviously stuck partly open. However, often valves are installed with pipe on the down-stream side. As in the picture, steam still blows past the valve, but since its inside of pipe, it's not obvious. Valves fail due to wear, corrosion and dirt/contaminates stuck in the valve seat.

That is not to say that copper corrosion failures are common in domestic (drinking) water systems. Considering the hundreds of miles of copper pipework which is installed in the UK each year, the number of failures is quite low. 1 INTRODUCTION Corrosion of
20/11/2020 · Copper pipes can be manufactured as soft or rigid copper and offer excellent corrosion-resistance and reliable connections. The three most common types of copper pipe used in residential and commercial construction are Type K, Type L, and Type M. A fourth type, used for drain-waste-vent, or DWV, piping, can be found in some older homes.
For steam systems constructed using copper tube of Types K or L, the maximum allowable pressure at which the system could be designed would be 120 psig. As shown in Tables 3a and 3b of the Copper Tube Handbook, the lowest maximum operating pressure for Type L copper tube is 127 psig (corresponds to 12-inch nominal Type L tube in annealed form).
