Material selection

Material selection

(OP)
Dear Members,
What is material Grade that can be used for following applications.
1. Diesel Loading and Unloading
2. Steam Pipes - Max Temperature - 450 degree C
3. Waste water pipes.

RE: Material selection

Look at various Power Piping Code sections offered by ASME below -

RE: Material selection

For diesel, I've just used carbon steel, A106 for piping, A105 for cast materials.

For steam piping at that temperature I don't know off the top of my head, steam piping is often just carbon steel, same material as I've suggested for diesel loading/unloading but that's not going to work at 450C.

For waste water, you'll need to provide some details where the water is coming from, pressure, temperature, what's in it, etc. I've seen anything from carbon steel to FRP.

RE: Material selection

There is more to this than asking and providing simple material recommendations. Get some help with an organization that specializes in piping design and piping codes.

RE: Material selection

This is worded very much like a cut and paste of an exam question. Are you a student?

RE: Material selection

for diesel carbon steel can be used:API 5L or A106 for pipe,A105 for forged fittings/valves/flanges,A234WPB for butt weld fittings,A216 WBC for cast components
for steam you can use the same material, bat the temperature shall be limited at 427 C max. Over Carbon moly steel or low alloy steel shall be used.
for waste water selection depends by water composition
