pH Impact In Boiler Tube

Degradation...hardening of the arteries...

The effect will be anything from nothing to dissolving the metal. I'm not sure what you mean by metallurgical effect. Metallurgy is the science of metals. What you are asking is basic chemistry. You should familiarize yourself with Arrhenius acids and bases. More important though, you should understand that because this is a boiler tube the Arrhenius equation will be important to understand.

From what material is the boiler tube made?

I recommend that the boiler tubes be made of metallic Lithium. The lightness of the metal will speed up the heat transfer to the fluid.

metallic Lithium

Redundant!

But I like your idea; all I would add would be an ignition source.

Yeah, I was redundant but not without a cause. I did not want people to confuse it with the pharmacology version of Lithium.

_{Some of this might be present in this thread, too.}

The use of an added "metallic" to lithium was read by me as way of identifying the phase state of the lithium. Is that no longer a recognized practice? We wouldn't want you using vapor state lithium as tubing material. I am not certain that an ignition source is completely necessary, in any case. It might interfere with the efficient packing of the tubes, and lead to focusing of the shrapnel.

it is alloy steel grade p 91 ( 9-12% cromium)

can you given data about your tubes boiler, and pH value when you said value is high and low ?

because i have same case with you about 1 year after, tubes ( Cooper, 20mmD, with pH water 10) in oil cooler air compressor leaked, but if you want to know detail effect, do lab test for your case,,,

Life for learn

In addition to the materials of the boiler tube, from what is the firebox and the boiler shell made?

Proper water treatment control in boilers pays handsome dividends in terms of longevity and availability of plant. Have you got a water treatment specialist involved in this pursuit, Guv?

How big is this flippin' boiler, for starters?

Dear Mr.Moammad rafi,

Fast corrossion and thinning away of metal where water is in contact, quality of steam will suffer and will lead to damage of Turbine rotor, stator etc.

The metallurgical effects are varied depending on more data not provided. Embrittlement is complex, try Googling it. That is easier than me typing it out.
