Ukuxhuma ipayipi nokufakwa kwengcindezi emaphakathi (300-999 psi) kudinga ama-flange anemicu ye-Class 300. Imicu engaphakathi kwe-flange yayinama-flange anentambo, eyaziwa nangokuthi ama-screw flange, anamathela emicu yangaphandle epayipini ngaphandle kokushisela. Ngokuvamile, ubuso balawa ma-flange buphakanyisiwe, buyisicaba, noma i-RTJ (inhlanganisela yohlobo lwendandatho). I-NPT (National Pipe Thread) kanye ne-BSPT (British Standard Pipe Taper) ziyizibonelo ezimbili zezixhumi ezinentambo. Ingxubevange ye-chromium-nickel uhlobo 304 yensimbi engagqwali imelana nokugqwala okulethwa umswakama, ukushisa, usawoti, ama-asidi, amaminerali, kanye nenhlabathi e-peaty. Ngaphezu kokuba ne-nickel eningi kunohlobo lwe-304 yensimbi engagqwali, uhlobo lwensimbi engagqwali engu-316 luqukethe ne-molybdenum yokumelana nokugqwala okungcono nakakhulu.
Ukuthuthukiswa nokukhiqizwa kwama-flange wentambo yensimbi engagqwali kuwukukhethekile kwe-JLPV. I-Austenitic stainless steel, i-duplex steel, ne-super duplex steel izinto eziyinhloko ezisetshenziswa inkampani ukwenza ama-flange wezimboni. Njengamanje, imikhiqizo yenkampani imakethwa ngempumelelo ezifundazweni nasezifundeni zaseShayina ezingaphezu kweshumi, okuhlanganisa iHong Kong neTaiwan, nase-United States, eCanada, eBrazil, eJalimane, e-United Kingdom, eFrance naseMpumalanga Ephakathi ngemikhiqizo enamathela Izindinganiso zaseMelika nezaseYurophu. Abathengi basekhaya nabamazwe ngamazwe bamunye ekuthakaseleni kwabo ikhwalithi yomkhiqizo.
