Titanium Yeeb Nkab Ua Tau Li Cov Qauv Thiab Cov Lus Qhia Tshwj Xeeb
Cov titanium yeeb nkab haum txheem ua ntej pom nyob hauv American Aerospace Cov Qauv. Tib qho kev cai thoob ntiaj teb muaj rau cov yeeb nkab titanium fittings hauv kev lag luam chemical yog ASTM B363 [5]. Nws tseem yog ib daim ntawv pov thawj feem ntau ua raws kev lag luam thoob ntiaj teb ntawm cov yeeb nkab titanium fittings. ASTM B363 tau tsim nyob rau xyoo 1961, thawj qhov kev hloov kho yog xyoo 1978, thiab nws tau hloov kho ntau zaus tom qab (piv txwv, hauv 83 thiab 87). Qhov tseeb tshaj plaws yog xyoo 1995, uas ua rau cov qauv txheem tiav ntau dua.
Xyoo 1994, Lub Chaw Tshawb Fawb Kev Tshawb Fawb Kev Nyab Xeeb Hauv Northwest muab cov tuam txhab tus qauv Q / XB1507—94" Titanium Taub Vuam Seamless Yeeb Fittings" ;. Nws zoo siab txais tos los ntawm chav tsim qauv. Kev qhia ntawm cov qauv no sawv cev rau kev pib ua haujlwm ntawm cov yeeb nkab titanium fittings hauv kuv lub teb chaws. Nws yog daim ntawv pov thawj tseem ceeb rau kev tsim, xa tawm, tsim thiab ua tiav ntawm cov yeeb nkab titanium fittings hauv kuv lub teb chaws.
Txhawm rau ua kom cov txheej txheem zoo dua los qhia cov txheej txheem kev tsim khoom, tsim thiab xaiv, khoom muag thiab xa tawm, teeb tsa thiab tsim kev ua haujlwm ntawm kuv lub teb chaws titanium cov yeeb nkab fittings, Lub Xeev Txoj Cai Roj thiab Tshuaj Kev Lag Luam tau muab" Titanium Butt Vuam Seamless Yeeb Fittings" kev lag luam thaum Lub Xya Hli 13, 1999 Txheem. Cov qauv no tau tsim los ntawm Quan Northwest Nonferrous Hlau Tshawb Fawb Lub Tsev Kawm. Tus txheej txheem naj npawb yog HG / T3651-1999, uas tau ua tiav rau lub Rau Hli 1, 2000. Qhov seem tsis sib haum ntawm cov yeeb nkab fittings stipulated nyob rau hauv cov qauv no yog sib npaug nrog American National Standard ANSI B16.9-1986" Forged Steel Butt Welding Yeeb Fittings" thiab kuv lub teb chaws' s Lub Teb Chaws Qauv GB 12459-90" Hlau Rho Taub Taub Sib Tw Seamless Yeeb Fittings" ;. Qhov yuav tsum tau ua rau cov yeeb nkab fittings thiab cov khoom tiav Cov khoom tsim thiab thaj chaw zoo ntawm cov yeeb nkab fittings yog sib npaug rau Asmeskas Kev Koom Tes rau Kev Ntsuas thiab Cov Khoom Siv cov qauv ASTM B363-95" Seamless thiab Seam Titanium thiab Titanium Alloy Butt Welding Yeeb Fittings" Cov.
