The
46、 Task Group examined mechanical properties of metallic materials used for API 6A and API 17D wellhead equipment for service above 250 F. A total of eleven different alloys meeting API 6A, PSL 3 conditions were supplied “in condition” by a variety of suppliers. Materials in this test program included
47、 alloys common to the oil and gas industry. The alloys tested included low alloy steels, martensitic, precipitation hardened and duplex stainless steels, and nickel alloys. Yield strength reduction ratios at temperatures of 300 F, 350 F, 400 F, and 450 F are reported. As a result of testing, yield s
48、trength reduction ratios at 300 F to 450 F ranged from 92 % to 87 % for the low alloy steels, 92% to 88% for the martensitic stainless steels 81 % to 73 % for super duplex, 99 % to 89 % for the precipitation hardened stainless steel and 94 % to 89 % for the nickel alloys. The reported results repres
49、ent an average over the different heats for each type of material. These results are intended to expand the data shown in API 6A, Annex G.vi1Metallic Material Limits for Wellhead Equipment Used in High Temperature for API 6A and 17D Applications1 ScopeTesting was performed in three phases, presented herein in chronological order as Phase I, II, and III. Initially, all testing was to be completed in two phases, but testing anomalies in Phase II prompted re-testing of some alloys in Phase III.Alloy candidates were recommended by AWHEM membership for analysis and confirmed by APIs ap
