I have gotten the price and it is really 10 times more expensive.
You do have a valid point for the corrosion issue.
If for example the body of butterfly valve is SS304 and the piping material is SS304L, will there still be corrosion issue?
SS304L is very uncommon to be used as butterfly valve...
@Gator LOL I'm sorry I am still a noob on this website, I didn't know how to attach a picture.
I am trying to think of ways to optimize my budget price to my customer.
My boss wants me to find out if we use normal butterfly valve with ductile iron body instead of SS304L body.
The price...
Conductivity is 20-25 microS/cm.
The water will only be in contact with the seat since the seat is placed fully under the body (see the picture below)
The ductile iron body will fully be coated to prevent corrosion.
My current issue is that I need to prove that there is no issue with choosing...
Hi guys,
Thank you all for your replies.
Yes, it is in marine condition.
Butterfly valve's body is not the wetted part because inside the body, there will be valve seat.
So the water will only be in contact with the disc and the seat.
As per the suggestion, I will ask this question to the...
Hi guys,
I am currently in a bind here.
Is there any ASME/ASTM code that specifies that body material of butterfly valve has to be the same as the pipe material?
So the service liquid is desalinated water, with TDS<10 ppm, pressure 7 bar, and T=40 deg C.
The pipe material that I have chosen is...
