Adequate material for handling and storare for acid water

[Cesarin2508]

Hi everyone,

In this moment i have been designing a system to handle water from a lake to a tank, but the water there in the lake have a ph=5.3, so i'm not sure which material should i have use for the tank and piping, i hope you can help me.

Regards.

I'd use a plastic system, pp/gre or pvc/gre or something like that.
Look at the properties of these materials.

If the system and tank will be pressurised above the plactic/PVC pipe/tank can handle, you need to use carbon steel pipe/tank with an accepted corrosion allowance. I guess this is the cheapest option.

However, you may need to check the water chemisty as well to find what causes the acidity for the suitability of carbon steel.

I am not an expert in this area, you will probably get expert advice in the forum.

Hi everyone,

I appreciate your answers and in fact i shall use plastic pipe (HDPE) for the longest pipe, but for the suction and discharge spool from pumps i need metallic pipe, i bet stainless steel 304 is a good option, but i need to support technically my client why i can use carbol steel as ASTM A53, it's involve cost so it's important define that, i hope you can understand and help me
