Introduction to API 607 ??fire test valve and API 6FA for valves and fire test 6A, 6D, generally only 90 ° rotation of the valve needs to be done 6D API 607, while others need to do API 6FA. API fire test standard? API 607-2010 Fire Test for Quarter-Turn Valves and Valves Equipped with Nonmetallic seats. 1/4 turn valves and valve seats refractory nonmetallic experiment? API 6FA-1993 (R2011) Specification for Fire Test for Valves. Valves refractory experimental specification API 6FD-2008 Specification for Fire Test for Check Valves. check valve specification refractory experimental fire tests diameter valves and pressure values ??assessed in the fire test, the diameter and pressure values ??are a little Specifications covering the large size, the specific example: the general path is covered twice specifications, 6NPS can cover 6-12NPS diameter of, 100DN can cover 100-200DN; and for the assessment is worth the provisions of the rated pressure coverage, 25PN can cover 25 :: 40PN. If there are multiple valves to be tested model that allows engineers to assess the next need several test reports. Fire test of the valve handle valve fire test requires companies to send samples to the testing laboratory, and then we witnessed the test certified engineers need to burn after 30 minutes of testing, issued tested, which do not meet the need to re-send samples tested for compliance with the certificate of compliance issued by us.
