Re: [MW:23383] DN 80 Carbon steel pipe

Thank you Alan, Jim & Prem,

It was a long ago used pipe. corroded so was examining it.  as a part of it, i analyzed the chemical composition. I was wondering, in IS 1239 there is no Si specification and this analysis shows it has Si content. That is why I was confused what grade should I call him.

thank you.

If you have the material Certificate of Compliance from the mill yes.

If you want to verify the material then this should be for your information only.

Be very careful trying to recertify material.

By doing so you could be assuming liability.

Dear Experts,

 

I have a 80 mm dia pipe. I have done its wet chemical analysis according to IS228. The result shows as below,

 

C - 0.06

Si - 0.55

Mn - 0.45

P - 0.024

S - 0.023

 

I checked standard IS 1239. As per this standard, the chemical composition should be (all max), C - 0.2, Mn - 1.3, S&P - 0.04%.

 

My question is, can I say my pipe is IS 1239 pipe?

 

Please suggest what grade is my pipe?

 

Thank you.

 

Sincerely,

Abdulkadar
