Ezinhlelweni zamapayipi ezimboni, amajoyinti okunwetshwa kwenjoloba ayingxenye ebalulekile engagcini nje ngokuxhuma ipayipi, kodwa futhi imunce ukudlidliza, inxephezelo yokushintsha kwezinga lokushisa, futhi idlale indima ebalulekile ekusebenzeni okuvamile kwesistimu yamapayipi.
Lesi sihloko sizokwethula usayizi, ukuhlukaniswa, isilinganiso sokucindezela, kanye nendlela yokuxhumana yamajoyinti okunwetshwa kwenjoloba.
Ubukhulu kanye nezigaba
Usayizi wamalunga okunweba enjoloba ngokuvamile unqunywa imingcele efana nobubanzi, ubude, kanye nenani lokunwetshwa.Ngokwezici zayo zesakhiwo nokusebenza, amajoyinti okwandisa irabha angahlukaniswa abe yizinhlobo ezilandelayo eziyinhloko:
- Ijoyinti yokunweba yerabha yebhola elilodwa: Ijoyinti yokunweba yerabha yebhola eyodwa inomzimba onwebekayo oyindilinga, ovame ukusetshenziselwa ukumunca ukudlidliza nokususwa kwamapayipi ngendlela eyodwa.
- I-double ball rubber expansion joint: Ijoyinti yokunweba yenjoloba ephindwe kabili inezindikimba ezimbili ezinwebekayo eziyindilinga, ezingamunca ukudlidliza nokususwa kwepayipi ezindleleni eziningi futhi inobubanzi obubanzi bezinhlelo zokusebenza.
- Ijoyinti yokwandisa irabha yamabhola amaningi: Ijoyinti yokunwetshwa kwenjoloba yamabhola amaningi inezindikimba eziningi ezinwebekayo eziyindilinga, ezinganikeza ukunwetshwa okukhulu nomthelela ongcono wokumunca ukudlidliza futhi ifanele amasistimu amapayipi ngaphansi kwezimo ezikhethekile zokusebenza.
Okubalulekile
- I-EPDM
- I-NBR
- KXT
Izinga lokucindezela
Isilinganiso sokucindezela kwamajoyinti okunwetshwa kwenjoloba sincike esakhiweni sawo, impahla, kanye nemingcele yokuklama.Ngokuvamile, izinga lokucindezela lamajoyinti okunwetshwa kwenjoloba lingahlukaniswa libe yingcindezi ephansi, ingcindezi ephakathi nendawo, kanye namazinga aphezulu okucindezela.Amajoyinti okunwetshwa kwenjoloba enengcindezi ephansi afanele izinhlelo zamapayipi okucindezela okuphansi, kuyilapho amajoyinti okunwetshwa kwenjoloba enomfutho ophakathi nendawo afaneleka kumasistimu amapayipi omfutho ophakeme, njengezinhlelo zamapayipi kumakhemikhali, uphethiloli, igesi yemvelo, neminye imikhakha.
Indlela yokuxhumana
Izindlela zokuxhuma zamajoyinti okunwetshwa kwenjoloba ngokuvamile zihlanganisa ukuxhuma kwe-flange, uxhumano lwentambo, nokuxhumeka okuhlangene okuqiniswayo.Phakathi kwazo, ukuxhumana kwe-flange kuyindlela evamile yokuxhumana, efana nokuxhuma kwe-pipeline flange.I-flange yejoyinti lokunwetshwa kwenjoloba ixhunywe ku-flange yepayipi ngamabholithi, okwenza uxhumano oluvaliwe.Ukuxhuma isikulufa kuyindlela elula nethembekile yokuxhuma amajoyinti okunweba enjoloba kumapayipi ngemicu yangaphakathi neyangaphandle.Uxhumano lwe-Splicing luyindlela yokuxhumana ekhethekile uma kuqhathaniswa, elungele izimo ezinezidingo eziphezulu zokudlidliza kanye nomthelela ezinhlelweni zamapayipi.
Amajoyinti okunwetshwa kwenjoloba, njengezixhumi ezibalulekile ezinhlelweni zamapayipi, anemisebenzi efana nokumunca ukudlidliza kanye nesinxephezelo sezinga lokushisa, futhi adlala indima ebalulekile emkhakheni wezimboni.Ngokuqonda ubukhulu, ukuhlukaniswa, isilinganiso sokucindezela, kanye nendlela yokuxhuma yamajoyinti okunwetshwa kwenjoloba, kungenzeka ukukhetha kangcono nokusebenzisa amalunga okunweba enjoloba, ukuqinisekisa ukusebenza okuphephile nokuzinza kwezinhlelo zamapayipi.Ngokuqhubeka okuqhubekayo kobuchwepheshe bezimboni, kukholakala ukuthi amajoyinti okunwetshwa kwenjoloba azoba nohlu olubanzi lwezinhlelo zokusebenza nentuthuko emkhakheni wokuxhunywa kwamapayipi.
