Carbon Content for SA 350 LF3

10/22/2009 4:48 AM

Dear All Member,

I have one vessel to fabricate using SA 203E + SS 316L Clad material for plate, SA 350 LF3 for flange. Design pressure is 7bar, design temperature is 90(max)/-70(min) degree Celsius and liquid content is Hydrocarbon +water. After request quotation from supplier for SA 350 LF3(flange), Carbon Equivalent is 0.559%. Any guideline from ASME regarding this matter and could we accept it.

Kindly, you all prompt respond are appreciated.

Thank you.

Dear Sir,

Please refer ASME Section II Part A, SA-350/SA-350M Clause S6 Table S6.1 where mentioned Max. carbon equivalent value which is permissible up to 0.48 So your material will not be accept as per code.

With reference to your answer the said table S6.1 is not including the LF3 Grads. So carbon equivalent value which is permissible up to 0.48 is not applicable in this case.

Don't evaluate the material SA350LF3 by carbon equivalent as well as no reference in ASME section II part A, but there are element percentage ... so compare each element one by one with table1 for SA350 LF3 in ASME II part A.

Dear Sir,

Now we have a problem with Flange (SA350 LF3 material) as following:

We use this flange for heater, the operating pressure is 122.5 bar (design pressure is 238 bar), this system is Fuel Gas Conditioning Skid. The parameters of Flange are:

-Schedule: XXS

- Size 50 mm (2")

- Rating 1500#

- Type: RTJ

- Material is SA350-LF3 / SA106 Gr.B

I don't know if this material could use in this case or not. Because with high pressure, I am affraid that this material could not withstand.

Pls help me to consult this problem.

Thank Sirs very much.
