Ikhwalithi nenani lepayipi elikhulu lensimbi eliwuketshezi
Igama eligcwele le-UHPE steel plastic composite pipe yi-UHMWPE steel plastic composite pipe. Ipayipi le-UHMWPE lenziwe ngepayipi le-UHMWPE nepayipi lensimbi ye-carbon ngenqubo yesayensi. Imodeli yokusetshenziswa ibonakala ngokuthi ipayipi yensimbi ene-flange isetshenziswa njengesendlalelo sangaphandle sesendlalelo sokuzivikela esiqinisayo, futhi ipayipi ye-polyethylene yesisindo se-molecular ultra-high isetshenziswa njengongqimba lwangaphakathi lwepayipi lesisekelo. Ipayipi eliyisisekelo lepayipi le-polyethylene lesisindo se-molecular yangaphakathi lidlulela endaweni ephumayo yepayipi iye emaphethelweni angaphandle obuso be-flange ukuze kwakheke isakhiwo esihlanganisa izici zepayipi le-polyethylene lesisindo esiphezulu se-molecular nepayipi lensimbi ye-carbon. , ukwakha isakhiwo esinokumelana nokuguga, ukumelana nomthelela Imishini yepayipi ekwazi ukumelana nokugqwala, ukumelana nengcindezi ephezulu, ukuzigcoba ngokwakho, ukusebenza kokumuncwa komthelela kanye ne-anti adhesion.
Isetshenziswa kabanzi ekuthuthweni komlotha wezimpukane nasekubuyiseleni ipayipi lamanzi lesistimu yokuphehla amandla ashisayo, umsila kanye nokuthuthwa okunodaka embonini yezimayini, ukuthutha okunengcindezi ephezulu kwamalahle empukane kanye nodaka lwamanzi amalahle endaweni yokulungisa amalahle embonini yamalahle, i-slurry kanye ne-corrosive medium equkethe. ezokuthutha ze-slag kwezinye izimboni. Ukuze kuhlangatshezwane nezidingo zebanga elide, umfutho ophakeme, ukumelana nokugqokwa okuphezulu, ukunamathela kanye nokukalwa, kuyathuthukiswa futhi kukhiqizwe Φ 89mm-- Φ 630mm ipayipi elivamile elivunguzayo elishiselwe ipayipi eliyinhlanganisela kanye nepayipi lensimbi engenamthungo lekhwalithi ephezulu eliyinhlanganisela ehlukahlukene. imininingwane. Izinhlobo eziningana ezingenhla zamapayipi ayinhlanganisela afakwe amapayipi e-UHMWPE, angasebenzisi ngokugcwele izakhiwo ezinhle kakhulu ze-UHMWPE, kodwa futhi afeze imisebenzi yokujwayela ukucindezela okukhulu, ukuthuthwa kwezindawo ezikude nokuvimbela ukulimala kwamandla angaphandle ngokusebenzisa inhlanganisela. ukuqiniswa, ukugcwalisa igebe lalolu hlobo lwamapayipi ahlanganisiwe e-China nokwandisa insimu yesicelo.
Inazo zonke izici zepayipi le-UHMWPE
Ngenxa yokuhlukaniswa okuphelele nokusebenzayo phakathi kwendawo yokudlulisela kanye nepayipi yensimbi, ithintana kuphela nesendlalelo sepayipi le-polyethylene lesisindo se-molecular ultra-high. Ngesakhiwo samangqamuzana esiyingqayizivele se-UHMW-PE, inazo zonke izici zepayipi le-polyethylene lesisindo samangqamuzana eliphakeme kakhulu, njengokumelana nokugqoka okuphezulu kakhulu, ukuzinza okuhle kwamakhemikhali, ukuzigcoba okuhle, okungewona ubuthi kubhayoloji, ukumelana nokushisa okuphansi okuyingqayizivele. , ukunganamatheli kwendawo, njll, Yelula kakhulu impilo yesevisi yepayipi.
Ipayipi le-UHMWPE ngokwalo linokumelana nomthelela omkhulu kakhulu. Njengepayipi lensimbi elinesendlalelo sokuzivikela esiqinisiwe, lingavimbela ngokuphumelelayo ukukhasa kwepayipi elingaphakathi, landise ikhono layo lokumelana nomthelela, ingcindezi, ukugoba namandla, futhi linamandla okuthwala okunamandla. Ingakwazi ukumelana nomfutho wamanzi ophakeme kunamapayipi epulasitiki obunjiniyela ajwayelekile, futhi ingafinyelela ku-6.4Mpa ngemva kokuhlolwa, Ipayipi le-UHMWPE Composite alikwesabi ukungqubuzana futhi ulwelwesi ngeke luphuke. Ifaneleka ngokukhethekile imishini yamapayipi okudlulisa umfutho ophezulu anendawo enzima.
Ngenxa yokuthi i-thermal conductivity yepayipi le-UHMWPE incane izikhathi ezingaphezu kwe-1000 kunensimbi, inganciphisa kakhulu izidingo zokushisa okushisayo zokuthutha amapayipi. Ukusebenza kwayo kwezinga lokushisa kuhle endaweni - 50 ℃ kuya ku-80 ℃, okubaluleke kakhulu ekuthuthweni koketshezi ezindaweni ezibandayo.
