I-PEX copper fittings iyizixhumi zensimbi ezisetshenziselwa ukuhlanganisa ama-PEX pipes (ama-pipes e-cross-linked polyethylene). Ngokuvamile zifaka ama-elbows, ama-tees, kanye nezixhumi, zifeza ukuhlanganiswa okuvalekile phakathi kwe-PEX pipe kanye ne-copper fitting ngalezi zindlela ezifana nokucindezela, ukwandisa, noma ukuhlanganiswa okunezintambo. Zisetshenziswa kabanzi ekwakheni ukuhlinzekwa kwamanzi, ezinhlelweni zokushisa, nasezinhlelweni zokushisa ngaphansi komhlaba.

Isici esiyinhloko se-PEX copper fittings sitholakala ekuxhumaneni kwezinzuzo ze-PEX pipes kanye ne-copper fittings: I-PEX pipes inikeza ukumelana nokugqwala, ukumelana nokudlidliza, kanye nempilo ende yokusebenza (ngaphezu kweminyaka engama-50), kanti i-copper fittings inikeza amandla aphezulu emishini, ukumelana nezinga lokushisa eliphezulu (ububanzi bezinga lokushisa obuvamile obusebenza -70℃ kuya ku-110℃), kanye nokumelana okuhle nokukhululeka, kuqinisekisa ukuxhumana okuthembekile. Le nhlanganisela ikakhulukazi ifanelekile ezinhlelweni ezidinga ukuphepha okuphezulu nokuhlala isikhathi eside, njengemithombo yamanzi ashisayo naphakathi kokupholisa. Ngokwezigaba nezindinganiso, i-PEX copper pipe fittings kumele ihambisane nohlobo lwe-PEX pipe (isb. PEX-a, PEX-b, noma PEX-c). Izindlela ezihlukene zokuxhumanisa zithinta ukumelana nokushisa kanye nokumelana nokuphuka komkhiqizo wepipa; ngakho-ke, kubalulekile ukuqinisekisa ukuthi i-pipe fittings kanye ne-PEX pipes zisezingeni elifanayo kanye nomkhiqizo lapho kukhethwa khona amafitting. Imikhiqizo kumele ihambisane nezindinganiso ezihlobene, njenge-GB/T 18992 mayelana nezilinganiso zengcindezi nezimvume zendawo, kanye ne-CJ/T205-2000 kanye ne-CJJ/T98-2003 mayelana nokumelana nokushisa, izinga lokuxhumanisa (ngokuvamile 70%-89%), kanye nokumelana nokudlidliza. Amafitting ngokwawo kumele adlule ku-95℃/1.5MPa hydrostatic test futhi ahlangabezane nezidingo zamandla okudonsa.
