Umgangatho kunye nobungakanani bombhobho wentsimbi owulwelo omkhulu
Igama elipheleleyo le-UHPE yentsimbi yeplastiki edibeneyo yombhobho yi-UHMWPE yentsimbi yeplastiki yombhobho odibeneyo. Umbhobho we-UHMWPE we-Composite wenziwa ngombhobho we-UHMWPE kunye nombhobho we-carbon steel ngenkqubo yesayensi. Imodeli yokusetyenziswa ibonakaliswe ngokuba umbhobho wentsimbi kunye ne-flange isetyenziswe njengomaleko wangaphandle wokhuseleko lokuqinisa, kunye ne-ultra-high molecular weight polyethylene pipe isetyenziswe njengoluhlu lwangaphakathi lombhobho wesiseko. Umbhobho wesiseko sombhobho we-polyethylene obunzima bemolekyuli wangaphakathi unabela ecaleni kombhobho wangaphandle ukuya kumda ongaphandle wesiphelo sobuso beflange ukwenza ulwakhiwo olupheleleyo, oludibanisa iimpawu ze-ultra-high molecular weight polyethylene pipe kunye necarbon steel pipe. , ukwenza ulwakhiwo olunokumelana nokunxiba, ukuxhathisa impembelelo Isixhobo sePipeline esinokumelana nomhlwa, ukumelana noxinzelelo oluphezulu, ukuzithambisa, ukusebenza kwefuthe lokufunxa kunye nokuncamathela.
Isetyenziswa ngokubanzi kuthutho lothuthu lwempukane kunye nokubuyisela umbhobho wamanzi wenkqubo yokuvelisa amandla ashushu, iintsalela zezimbiwa kunye nothutho oluludaka kwishishini lezemigodi, ukuthuthwa koxinzelelo oluphezulu lweempukane zamalahle kunye nodaka lwamanzi amalahle kwindawo yokulungiselela amalahle kushishino lwamalahle, uludaka kunye nendawo engcolisayo. uthutho lwe-slag kwamanye amashishini. Ukuze kuhlangatyezwane neemfuno zomgama omde, uxinzelelo oluphezulu, ukumelana nokunxiba okuphezulu, ukuncamathela kunye nokukalwa, kuyaphuhliswa kwaye kuveliswe Φ 89mm-- Φ 630mm umbhobho odityanisiweyo odityanisiweyo oqhelekileyo wombhobho odityanisiweyo kunye nomgangatho ophezulu wombhobho wentsimbi ongenamthungo odibeneyo wemibhobho eyahlukahlukeneyo. iinkcukacha. Ezi ndidi zingentla ezahlukeneyo zemibhobho edityanisiweyo zifakwe kwimibhobho ye-UHMWPE, engasebenzisi ngokupheleleyo kuphela iimpawu ezigqwesileyo ze-UHMWPE, kodwa ikwaphumeza imisebenzi yokuqhelanisa noxinzelelo oluphezulu, ukuthuthwa kwentsimi yomgama omde kunye nokuthintela umonakalo wamandla angaphandle ngokusebenzisa i-composite. ukuqiniswa, ukuzalisa isithuba solu hlobo lwemibhobho edibeneyo e-China kunye nokwandisa indawo yesicelo.
Inazo zonke iimpawu ze UHMWPE umbhobho
Ngenxa yokuzahlula okupheleleyo kunye nokusebenzayo phakathi kwendawo yokudlulisa kunye nombhobho wensimbi, idibanisa kuphela kunye ne-ultra-high molecular weight polyethylene pipe layer. Ngolwakhiwo olulodwa lwemolekyuli ye-UHMW-PE, inazo zonke iimpawu ze-ultra-high molecular weight polyethylene pipe, ezifana nokumelana nokunxiba okuphezulu kakhulu, ukuzinza kweekhemikhali okugqwesileyo, ukuzithambisa okulungileyo, okungeyotyhefu kwibhayoloji, ukuxhathisa okukodwa kobushushu obuphantsi. , umphezulu wokungabambeleli, njl, Ukwandisa kakhulu ubomi benkonzo yombhobho.
Umbhobho we-UHMWPE ngokwawo unokumelana nempembelelo ephezulu kakhulu. Njengombhobho wensimbi kunye nomgangatho okhuselekileyo wokukhusela, unokuthintela ngokufanelekileyo ukukhwela kombhobho wangaphakathi wangaphakathi, ukwandisa amandla okumelana nempembelelo, uxinzelelo, ukugoba kunye namandla, kwaye unamandla okuthwala. Iyakwazi ukumelana noxinzelelo lwamanzi oluphezulu kunemibhobho yeplastiki yobunjineli obuqhelekileyo, kwaye inokufikelela kwi-6.4Mpa emva kokuvavanya, Umbhobho we-UHMWPE we-Composite ayesabi ukungqubana kunye ne-lining ayiyi kuphuka. Ilungele ngokukodwa izixhobo ezithile zemibhobho yosasazo olunoxinzelelo oluphezulu olunobume oburhabaxa.
Ngenxa yokuba i-thermal conductivity yombhobho we-UHMWPE ingaphezulu kwamaxesha angama-1000 amancinci kuneyentsimbi, inokunciphisa kakhulu iimfuno zokufakelwa kwe-thermal yokuthutha imibhobho. Iqondo lobushushu lisebenza kakuhle kwimo engqongileyo - 50 ℃ ukuya kuma 80 ℃, nto leyo ibaluleke kakhulu ekuthuthweni kolwelo kwiindawo ezibandayo.
