What materials are people using for the backflush tubes in ammonium sulfate saturators these days?
Thread Content
The backflush tubes in the ammonium sulfate saturator often leak. 316L stainless steel, copper, and steel-reinforced composite pipes have all failed to work – does anyone know of any new types of pipes that could be used as a substitute? ?
PE pipes – we’re getting them installed right away!
We use 316L, or material 904; 316L gives good performance
Using qualified 316L stainless steel is an option; choosing a fluorinated lining inner tube is also possible.
It’s not that the material is unsuitable; it’s the quality of the material that’s an issue. Qualified 316L should not present any problems
Steel framework composite pipes can handle this; the key lies in the elbows – avoid using 90-degree elbows instead opt for two 45-degree elbows, which will reduce resistance and erosion and extend the service life.
