Pipeline material for high-salinity wastewater
Thread Content
I would like to ask the experts: For high-salinity wastewater with a salt concentration of 11,000 mg/l and containing various types of salts, what is the appropriate material for the pipes? Operating temperature: room temperature; pumping pressure: 1.6 MPa

It’s just a matter of how long it’s used. 800H works too.
Duplex stainless steel, 2205 or 2257
Can 20# seamless carbon steel with internal anti-corrosion treatment be used? Party A finds stainless steel to be too expensive

For long-term use, the temperature of the medium in which it is used must be kept below 250 degrees Celsius, and only 316L stainless steel is capable of withstanding such conditions. But 2205 is more corrosion-resistant than 316L
Check the components of the salt: it contains chlorides; at high temperatures, titanium material is preferred； At low temperatures, duplex stainless steel is also suitable ； Other types of salt-resistant duplex stainless steels are sufficient ； When the temperature is below 80 degrees, plastic-lined or fluorine-lined pipes can be used, but it is necessary to ensure that there are no solid particles present, otherwise erosion will be severe.
