[MW:2116] Re: preheat SA- 516 gr 70

Dear Saul,
 
             We are also tank fabricator but we never do preheating.It is not the requirement as per API 650 if you have proper WPS with supporting PQR.We have welded 35mm A 516 GR 70 in our last project without preheating without anyproblem.

Dear   all

 

We are   API 650 steel tanks with  steel ASTM  516 gr70 and our client requests that preheat to 70°C - 100°C is this correct? The API 650   code section 7-1 that says that  preheat at 10°C



thanks all

 

 

 

Cordial saludo

Kind regards
