API 6FA Fire test

API 6FA Fire test

API 6FA Fire test

(OP)
Hi,

Could anyone out there please tell me if there are any significant differences between API 607 and API 6FA, with respect to valve qualification e.g. if I test a 4" CL150 Ball Valve, what other sizes and class ratings will be covered.

Cheers  

RE: API 6FA Fire test

Graybags,
        I think there are no big differences... but I should check by reading and understanding the relevant standards, of course.
   In the meantime, mybe you'll find interesting to take a look at Thread408-97580...

Bye,  'NGL

RE: API 6FA Fire test

      According to API Std.607, 4th edition (1993), pages 7 and 8, paragraph "4.4  Valve Qualification" (see Tables 3 and 4):
        -    a 4" valve qualifies valve diameters from 3" to 6";
        -    a 8" valve qualifies all above valve diameters;
        -    a class 150 valve qualifies classes 150 and 300;
        -    a class 600 valve qualifies classes 600 and 900;
        -    a carbon steel body qualifies all body materials listed in Group 1 of ASME B16.34, Table 1;
        -    a stainless steel body qualifies all body materials listed in Groups 2 and 3 of ASME B16.34, Table 1.

      Qualification of fasteners' materials (para. 4.4.8) and "soft" parts (PTFE and other polymers - para. 4.4.9) should also be considered...    

      I'll add other information and possibly a comparison as soon as I can consult API Std.6FA too.

      In the meantime, try also reading Thread809-70969.

Hope this helps,     'NGL
