## Pipe Weight by Surface Area

## Pipe Weight by Surface Area

(OP)

Good Day Everyone,

Could someone help me calculating the weight of pipe because the painting company is calculating the price through surface area of pipe and its weight and weight of the paint in microns.

Example Given are:

Pipe OD is 0.53 m2/Meter

Pipe Thickness is 7.11 MM

Pipe Weight 28.83 Kg/Meter

Pipe Length is 6,000 MM

Paint Micron is 1 Micron = 7.625 Grams

Please help me how to calculate the total weight of given above using 6,000 MM pipe length.

Also, it was painted by hot dipped galvanized including inside surface of pipe.

Your help is highly appreciated.

Thank you

JOHN

## RE: Pipe Weight by Surface Area

bare pipe weight= 28.83*6000/1000=... kg

Paint Micron is 1 Micron = 7.625 Grams (Paint thk is 1 micron = 7.625 gr/m2)

Paint weight= 7.625*0.53*6000/1000=... gr

## RE: Pipe Weight by Surface Area

Somethings rather strange here.

I've never heard of painting companies charging by weight of pipe.

Paint comes in thicknesses higher than 1 micron primer is often 25 and top coat 50-100 microns.

~Make sure you're not confusing "mils" ( 1/1000") with a micron

Why you need to paint galvanized pipe and also work out the cot for a 6 metre length of pipe is beyond me

Never heard of hot dip galvanising as "paint". Quote"Also, it was painted by hot dipped galvanized including inside surface of pipe". What type of brush do you use to paint a pipe with "hot dip galvanising" ?

The service for the pipe is for Service Air use for chemical processing plant.

The galvanizing company is weighing the spool thru weight bridge ( the trailer will pass the weighing scale without spool and back again with spool) result weight is thru subtracting.

But we discuss with our seniors that we lost some money of this because the flange with 300 LB has too much weight but the surface is just small. same with the o'let.

As of now, we are finding calculation that would fairly give us the correct weight.

Maybe you could have any formula that can help us finding the correct weight of spool after galvanizing.

Pipe schedule is 40, length is 6000

micron after galvanizing is 131.

thanks everyone

Pipe OD doesn't change with pipe schedule, only ID

Volume x density of dried galvanising = weight.

Multiply by number of pipe spools.

## RE: Pipe Weight by Surface Area

So: Do the real math. Calc the actual area of the pipe (inside and outside) per foot (or per meter). Calc the number of flanges, the exposed area of each flange, the total length of the straight "pipe" and elbows, the number of spools. It's your project, your company's profits being lost (? - Or maybe gained) by your your estimate that YOU need to defend. Just do the bloody math.

## RE: Pipe Weight by Surface Area

So, what the is the OD and ID of the 6 meter schedule 40 pipe? (Hint: This is a homework assignment for the original poster.) How many 300 lb flanges are on each spool (2, probably).

The rest is simple algebra.
