Kahor intaadan kulmingarab, nadiifi oo nadiifidusha flange, gaar ahaan dusha daboolka. In la isu keeno aflange-alxan leh, Geli dhamaadka tuubada 2/3 ee dhexroorka gudahagarabiyo baralxanka garabkatuubada. Haddii ay tahay tuubo shahaado ah, bar alxanka xagga sare ka soo jeedda, ka dib ka hubi booska flange-ka cabbirka jihooyin kala duwan adigoo isticmaalaya 90° labajibbaaran oo u beddel wejiga daboolka meel siman oo ku beegan xariiqda dhexe ee tuubada. Ka dib qaladaad la'aan, bar welded barta labaad ee hoose.
Hubi oo sax booska garabka bidix ilaa midig adiga oo isticmaalaya 90° xaakin Ka dib marka aad gudubto imtixaanka, bar alxanka dhibcaha saddexaad iyo afaraad si aad u dhammaystirto alxanka dhibcaha iyo hagaajinta flange. Marka la isu keeno labo ka mid ahgarbaha, godadka boodhka ah ee qalabka dambe ee qalabka dambe waa in ay la socdaan godadka boodhka ee u dhigma ee flange go'an oo barbar socda garabka go'an. Cabbirka flange aaladda danbe waa in aanay ka badan 1.5‰ dhexroorka flange oo ka badan 2 mm.
