Stainless Steel for High Pressure Piping in SWRO Plants. Are there any Options?
ثبت نشده
چکیده
Service experience from 27 seawater reverse osmosis (SWRO) plants confirms that there is an evident risk of corrosion if wrong steel grade is used for the high pressure piping. Neither 316L nor 317L possesses sufficient corrosion resistance. Not even highly alloyed grades like 2205 and 904L show reliable service performance. However, no corrosion has been reported for 254 SMO, which has been used in 16 full strength SWRO plants and several plants using high salinity brackish water.

In this paper the ratcheting behavior of carbon steel(ASTM A106B) and stainless steel(304L) elbows is studied under steady internal pressure and in-plane external moments at frequencies typical of seismic excitations. The finite element analysis with the nonlinear isotropic/kinematic (combined) hardening model has been used to evaluate ratcheting behavior of the elbows. Material parameters have...

Seawater reverse osmosis desalination (SWRO) requires less energy compared with the distillation method and thus is an important technology except Middle Eastern countries whereenergy costs are higher. Recently, even Middle Eastern countries where the distillation method is still a major technology, have begun adopting the RO method in new desalinationplants in line with government ...
