Ukuxhunywa kwamapayipi okubhoboza uwoyela kuyingxenye ebalulekile yepayipi lokubhoboza, elihlanganisa iphinikhodi nokuxhunywa kwebhokisi kuwo wonke umkhawulo womzimba wepayipi lokubhoboza. Ukuthuthukisa amandla okuxhuma, ubukhulu bodonga lwepayipi ngokuvamile buyanda endaweni yokuxhuma. Ngokusekelwe endleleni ukujiya kodonga okwandayo, ukuxhumana kungahlukaniswa ngezinhlobo ezintathu: ukucasuka kwangaphakathi (IU), ukucasuka kwangaphandle (EU), kanye nokucasuka kwangaphakathi-kwangaphandle (IEU).
Kuye ngohlobo lwentambo, ukuxhunywa kwepayipi lokubhoboza kuhlukaniswe ngezinhlobo ezine eziyinhloko ezilandelayo: I-Flush Yangaphakathi (IF), Imbobo Egcwele (FH), Evamile (REG), kanye Nokuxhumana Okunezinombolo (NC).
1. Uxhumano Lwe-Internal Flush (IF).
Ukuxhumana kwe-IF kusetshenziswa ngokuyinhloko kumapayipi okubhola e-EU kanye ne-IEU. Kulolu hlobo, ububanzi bangaphakathi besigaba esiqinisiwe sepayipi bulingana nobubanzi bangaphakathi bokuxhuma, obulingana nobubanzi bangaphakathi bomzimba wepayipi. Ngenxa yamandla aphansi, ukuxhumeka kwe-IF kunezinhlelo zokusebenza ezivamile ezinomkhawulo. Ubukhulu obujwayelekile buhlanganisa ibhokisi lobubanzi bangaphakathi obungu-211 (NC26 2 3/8″), olunochungechunge lwephini olugobhoza ukusuka ekugcineni oluncane ukuya ekugcineni okukhulu. Inzuzo yoxhumo lwe-IF ukumelana nokugeleza okuphansi koketshezi lokumba, kodwa ngenxa yobukhulu bayo obungaphandle, ijwayele ukuguga kalula uma isetshenziswa.
2. Uxhumano Lwembobo Egcwele (FH).
Ukuxhunywa kwe-FH kusetshenziswa kakhulu amapayipi okubhola e-IU kanye ne-IEU. Kulolu hlobo, ububanzi bangaphakathi besigaba esijiyile bulingana nobubanzi bangaphakathi bokuxhuma kodwa buncane kunobubanzi obungaphakathi bomzimba wepayipi. Njengoxhumano lwe-IF, intambo yephinikhodi yokuxhuma kwe-FH idonsa kusukela kwencane kuya ekugcineni okukhulu. Intambo yebhokisi inobubanzi obungaphakathi obungu-221 (2 7/8″). Isici esiyinhloko soxhumano lwe-FH umehluko wamadayimitha angaphakathi, okuholela ekuqineni kokugeleza okuphezulu koketshezi lokumba. Kodwa-ke, ububanzi bayo obungaphandle obuncane buyenza ingagqoki kangako uma iqhathaniswa noxhumo lwe-REG.
3. Ukuxhumana Okuvamile (REG).
Izixhumanisi ze-REG zisetshenziselwa ikakhulukazi amapayipi okubhoboza e-IU. Kulolu hlobo, ububanzi bangaphakathi besigaba esiqinisiwe buncane kunobubanzi obungaphakathi boxhumano, okuyinto encane kunobubanzi obungaphakathi bomzimba wepayipi. Ububanzi bangaphakathi bochungechunge lwebhokisi ngu-231 (2 3/8″). Phakathi kwezinhlobo zokuxhuma zendabuko, ukuxhumeka kwe-REG kunokumelana okuphezulu kakhulu kokugeleza koketshezi lokumba kodwa ububanzi obungaphandle obuncane kakhulu. Lokhu kunikeza amandla amakhulu, kuyenza ifaneleke kahle amapayipi okubhola, izinsimbi zokubhoboza, namathuluzi okudoba.
4. Ukuxhumana Okunezinombolo (NC)
Uxhumo lwe-NC luwuchungechunge olusha olungena kancane kancane esikhundleni se-IF kanye noxhumo oluthile lwe-FH olusuka kumazinga we-API. Uxhumano lwe-NC luphinde lubizwe njengochungechunge lwe-National Standard coarse-thread e-United States, olufaka imicu yohlobo lwe-V. Okunye ukuxhumeka kwe-NC kungashintshana nokuxhumana kwama-API amadala, okuhlanganisa i-NC50-2 3/8″ IF, NC38-3 1/2″ IF, NC40-4″ FH, NC46-4″ IF, kanye ne-NC50-4 1/2″ IF. Isici esibalulekile soxhumo lwe-NC ukuthi agcina ububanzi be-pitch, i-taper, i-thread pitch, nobude bentambo yokuxhuma ama-API amadala, okwenza kuhambisane kakhulu.
Njengengxenye ebalulekile yamapayipi okubhoboza, ukuxhunywa kwamapayipi okubhoboza kuyahluka kakhulu ngokwamandla, ukumelana nokugqokwa, nokumelana nokugeleza koketshezi, kuye ngohlobo lwentambo yawo kanye nendlela yokuqinisa ukuqina kodonga. Izixhumanisi ze-IF, FH, REG, kanye ne-NC ngayinye inezici ezihlukile futhi ifanele izimo zokusebenza ezihlukene. Ngokuthuthuka kwezobuchwepheshe, ukuxhumeka kwe-NC kancane kancane kungena esikhundleni sezindinganiso ezindala ngenxa yokusebenza kwayo okuphezulu, okuba ukukhetha okujwayelekile emisebenzini yesimanje yokumba uwoyela.
