304 zitsulo zosapanga dzimbiri zosapanga dzimbiri zokhala ndi mipanda iwiri zosinthika zowongoka molunjika chitoliro chamadzi chitoliro chowongolera chitoliro 1 mndandanda
Zopangira zitsulo zosapanga dzimbiri zosapanga dzimbiri zimalimbana ndi dzimbiri kuchokera ku mankhwala a caustic, madzi owononga, mafuta, ndi mpweya, komanso kupirira kupsinjika ndi kutentha kwambiri pakuyika mipope ndi kukonza chakudya ndi mkaka.Zopangira zitoliro zokhala ndi ulusi zimalumikizidwa mbali zonse ziwiri.Ulusi wachikazi uli mkati mwa cholumikizira.Ulusi wachimuna umakhala kunja kwa ulusi waukazi.Ulusi wa NPT (American National Standard Pipe Threads) ndi BSPT (British Standard Pipe Threads) zimasiyanitsidwa ndi ngodya yake ya taper.Palinso zolumikizira zowongoka (NPS) za ulusi wapaipi ndi ma metric (M) mapaipi.Kuyika kwa mapaipi a metric kumazindikiridwa ndi m'mimba mwake mwadzina wakunja ndi phula la ulusi.Kulumikizika uku sikufuna zomatira kapena zomatira, koma tepi ya PTFE imakhala yolimba.Zopangira ulusi zimakhala zazikulu komanso zowoneka mosiyanasiyana.
Class 150 zopangira zitsulo zosapanga dzimbiri zimalumikizana ndi chitoliro chapakati (300-999 psi).Zopangira zitoliro zokhala ndi ulusi zimalumikizidwa mbali zonse ziwiri.Ulusi wachikazi uli mkati mwa cholumikizira.Ulusi wachimuna umakhala kunja kwa ulusi waukazi.Maulumikizidwe amizere amaphatikizapo NPT (National Pipe Thread) kapena BSPT (British Standard Pipe Taper), ndikugwiritsa ntchito tepi ya PTFE kuti musindikize.Chitsulo chosapanga dzimbiri cha 304, chromium-nickel material, chimakana dzimbiri chifukwa cha madzi, kutentha, madzi amchere, ma asidi, mchere, ndi dothi la peaty.Chitsulo chosapanga dzimbiri cha Type 316 chili ndi faifi tambala wambiri kuposa 304 zosapanga dzimbiri, kuphatikiza molybdenum, chifukwa chokana dzimbiri.
