Txuas nruab nrab-siab yeeb nkab thiab fittings (300-999 psi) yuav tsum tau Class 300 threaded flanges. Cov xov nyob rau hauv lub flange bore ntawm threaded flanges, tseem hu ua screwed flanges, txuas mus rau sab nraud threads ntawm ib tug yeeb nkab yam tsis muaj vuam. Feem ntau, lub ntsej muag ntawm cov flanges no tau tsa, tiaj tus, lossis RTJ (ntiv nplhaib-hom sib koom ua ke). NPT (National Pipe Thread) thiab BSPT (British Standard Pipe Taper) yog ob qho piv txwv ntawm cov xov txuas. Cov chromium-nickel alloy hom 304 stainless hlau yog resistant rau corrosion coj los ntawm ya raws, tshav kub, salinity, acids, minerals, thiab peaty av. Ntxiv rau qhov muaj nickel ntau dua li hom 304 stainless hlau, hom 316 stainless hlau kuj muaj molybdenum kom zoo dua corrosion kuj.
Kev txhim kho thiab tsim cov hlau stainless xov flanges yog ib qho tshwj xeeb ntawm JLPV. Austenitic stainless hlau, duplex steel, thiab super duplex steel yog cov ntaub ntawv tseem ceeb siv los ntawm lub tuam txhab los ua kev lag luam flanges. Tam sim no, lub tuam txhab cov khoom lag luam tau ua tiav hauv ntau tshaj kaum lub xeev Suav thiab cheeb tsam, suav nrog Hong Kong thiab Taiwan, thiab hauv Tebchaws Meskas, Canada, Brazil, Lub Tebchaws Yelemees, United Kingdom, Fabkis, thiab Middle East rau cov khoom lag luam uas ua raws. American thiab European qauv. Cov neeg siv khoom hauv tsev thiab thoob ntiaj teb tau koom ua ke hauv lawv txoj kev qhuas rau cov khoom zoo.
