Kazi kuu ya kiungo cha upanuzi wa flange ni kuhimili shinikizo na msukumo ndani ya bomba.Fidia bomba kutokana na upanuzi wa mafuta na shrinkage baridi unasababishwa na mabadiliko ya kawaida, yaani fidia bomba axial makazi yao.Wakati huo huo rahisi kuunganisha pampu au ufungaji valve, matengenezo na disassembly.Ikiwa shinikizo la papo hapo la bomba ni kubwa sana au uhamishaji unazidi uwezo wa upanuzi wa kifaa chenyewe cha upanuzi, bomba la upanuzi la kifaa cha upanuzi litavunjwa, na kusababisha uharibifu wa pampu zinazohusiana, vali, na hata bomba zima. .Sababu kwa nini viungo vya upanuzi vinaweza kufanya kazi katika mazingira magumu ni nyenzo na matibabu maalum ya uso.
Kipanuzi cha flange kimoja hutumiwa hasa katika uhamishaji wa mitambo na uhamishaji wa joto wa mfumo wa bomba ili kunyonya mtetemo na kupunguza kelele.Inaweza kufanya ufyonzaji wa uhamishaji katika pande zote.Wakati wa kufunga kipanuzi, rekebisha urefu wa ufungaji wa ncha zote mbili za bidhaa au flange.Sawa kaza karanga za gland kwa diagonally, na kisha urekebishe karanga za kikomo, ili bomba liweze kupanuliwa kwa uhuru na kupunguzwa ndani ya aina mbalimbali za upanuzi na kupungua.Funga kiasi cha upanuzi ili kuhakikisha uendeshaji wa bomba.
