Thanks for the input. Erosion happens in elbow and slanted pipe portion below. Please read the problem statement. This service is totally highly abrasive slurry contains pet coke, ash, water. The solids are in 4-10 wt% solids. which is the main cause of erosion.
Initially with SS304...
Not PVD.
its PVDF Polyvinylidene fluoride. It is commonly known as Kynar.
I have attached document upon this PVDF for a reference. @Edstainless steel.https://files.engineering.com/getfile.aspx?folder=381dca51-f78f-46de-aa1a-4db5a4f633d1&file=ar-prevent-corrosion-with-pvdf.pdf
Just an update . I am exploring more on PVDF lining/coating. which studies claims to be of more abrasion restiveness. I am talk with few vendors as well.
If any one could throw some light on this PVDF on slurry abrasion. It will be helpful.
Thank you all for your valuable inputs. I ll look...

Thanks for the reply.
I have looked upon the SS2205, it have indeed better hardness property.But it has lack of abrasion resistance property.
Nitronic - Is it possible for making pipe section using Nitronic ?
HVOF - it is good idea with TC coating. But HVOF is limited to maximum...
Hello everyone,
Problem : Frequent failure of 8" SS304L pipe line due to the slurry erosion.The pipeline faces a vertical ( top to bottom) flow and the isometrics of the pipe has two elbows 30 and 45 degree. The erosion mainly takes place the hitting edges of these elbow outlet regions.
