[MW:1615] Re: API 5L X85

Babu,
 
In API 5L
PSL 1 Grades A25, A, B, X42, X46, X52, X56, X60, X65 & X70.
PSL 2 Grades B, X42, X46, X52, X56, X60, X65, X70 & X80
 
When carbon content less than 0.12% use the below calculation:
 
CE = C+Si/30+Mn/20+Cu/20+Ni/60+Cr/20+Mo/15+V/10+5B
 
When carbon content greater than 0.12% use the below calculation:
 
Carbon Equivalent (CE) = C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15
 
Regards,
S.Senthilkumar

Hi,

 

I have the material, API 5L X85 bought from two suppliers, and we developed the Procedure for welding of this material for the T, K, and Y joint.

 

The carbon equivalent of this material vary by considerable amount by two suppliers (0.55, 0.78),

 

As per D1.1, CE is not an essential variable, but metallurgical point of view, there will be major changes in the weldments properties and behaviour,

 

How to take it into account this variation in Procedure? Is it allowable variation as per API 5L spec?
 
Thanks & Regards,
 
K.Babu
