CovISO loj flangetus qauv hu ua LF, LFB, MF lossis qee zaum tsuas yog ISO flange. Raws li hauv KF-flanges, cov flanges tau koom nrog lub nplhaib nruab nrab thiab ib qho elastomeric o-ring. Ib qho ntxiv caij nplooj ntoos hlav-loaded ncig clamp feem ntau yog siv nyob ib ncig ntawm qhov loj-inch o-rings los tiv thaiv lawv los ntawm dov tawm ntawm lub nplhaib nruab nrab thaum mounting.

ISO loj flanges tuaj nyob rau hauv ob ntau yam. Lub ISO-K (los yog ISO LF) flanges tau koom nrog ob-claw clamps, uas clamp mus rau lub voj voj voog ntawm lub raj sab ntawm flange. ISO-F (los yog ISO LFB) flanges muaj qhov rau txuas ob lub flanges nrog bolts. Ob lub raj nrog ISO-K thiab ISO-F flanges tuaj yeem koom ua ke los ntawm clamping ISO-K sab nrog ib leeg-claw clamps, uas tom qab ntawd bolted rau lub qhov ntawm ISO-F sab.

ISO loj flanges muaj nyob rau hauv qhov ntau thiab tsawg ntawm 63 mus rau 500 hli nominal raj txoj kab uas hla.
