CHILLED WATER PIPE-MATERIAL SPECS 1

[moideen]

which material is best for chilled water piping. we previously used gi then now mild steel,and ABS.i would like know the updated advanced standards following in the present industry. thanks

Chilled Water is a pretty standard service; CS and SS are frequently used without any issues.

RVAmeche; willuse the SS for chilled water? is this affordable to use SS for large chiller plants?

 

[RVAmeche]

It depends on the process requirements. We've had some facilities want to use SS because the connecting equipment (breweries, etc) are sensitive to rust/contaminants and they wanted a "clean" chilled water supply.

For these questions you really need to think about what you mean by "best?"

Cheapest?
Easiest to obtain in your location?
Easy to install?
Corrosion resistance required or not?
Pressure rating required
temperature required

Everyone will have a different interpretation of which of those is more important and hence "best" for their situation.

In design one size / material doesn't fit all

The main concern is corrosion resistant; strength and medium cost which means inexpensive for large capacity chilled water plant. I have a project around 13-year-old 6000-ton capacity chilled water plant where ABS pipe is used to entire circuit. it is usual now the leakage on branches and one major leak happened on underground pipe and it is rectified. Planning to convert the system to steel pipe. Two specs are considering with ERW black steel and carbon steel. I would like to know which is best for chilled water system….

Ah ..... at last we have dragged out the real question from our mid-eastern friend

Never, never never tell us what the issue is on the original post ....

The first post should always be sufficiently vague as to confuse everyone and make an answer impossible...

Some good examples are:

- "Dearest ....Need large grey bolt....

- "Why did the client ask me to use this particular steel ?"

and, my all-time favorite....

- "What will happen if I push Switch #25 ????

Also, Never, never, never use "Please" and "Thank you" ....

Dear moideen,

You are walking backwards.

Now-a-days GRE piping is extensively used. However, if the workmanship is poor, you would encounter leaks all over.

Dhurjati Sen: thank you for the information.i have no experience with this pipe GRE. do you mean this is GI with epoxy pipe???? what is precautions to ensure the workmanship that what type of know how required in workmanship and cost difference between black steel . thanks
