About API 607 ??fire test valves and valve API 6FA for fire test 6A and 6D, usually only 90 ° rotation of the valve needs to be done 6D API 607, while the other needs to do API 6FA. API standard fire test? API 607-2010 Fire Test for Quarter-Turn Valves and Valves Equipped with Nonmetallic seats. 1/4 turn valves and valve seats nonmetallic fire experiment? API 6FA-1993 (R2011) Specification for Fire Test for Valves. Valves refractory test specification API 6FD-2008 Specification for Fire Test for Check Valves. check valve specification refractory experimental fire tests diameter and pressure in the valve fire test assessment, the size and pressure values ??are from small Specifications covering large size, the specific example: the general path is covered twice the size, 6NPS can cover 6-12NPS diameter of, 100DN can cover 100-200DN; and for pressure rating is worth assessing requirements coverage, 25PN can cover 25 :: 40PN. If more than one valve models need to be tested, allows engineers to assess the next few test report required. Valve valve handle fire test of fire test requires companies to send samples to the testing laboratory, then our certified engineers witnessed the test, you need to burn after 30 minutes of testing, issued tested, do not meet the need to re-send samples tested for compliance with the Certificate of Compliance issued by us.
