Incazelo Yomkhiqizo

I-CHHUANGRONG PE100-RC DN20-DN1600 HDPE PIPE

Izinto zamapayipi e-polyethylene zidlule izigaba ezi-4.

Isigaba sokuqala saqala ngawo-1950, futhi ikakhulukazi sasihlanganisa ama-macromolecule e-polyethylene ngaphandle kwe-branching;eyesibili yayiyimpahla ye-PE80;eyesithathu yayiyi-PE100;owesine waphasa umklamo wesakhiwo samangqamuzana.

Ukuqina okuphezulu kwepayipi le-polyethylene PE100-RC aligcini nje ngokugcina ukuqina okuhle kakhulu, ukumelana nokugqokwa okuhle nokumelana nokugqwala kwepayipi le-PE100, kodwa futhi linezici ezilandelayo:

1, Ngokuqina okuphezulu:high toughness polyethylene PE100-RC ipayipi elongation ngesikhathi sekhefu ezingaphezu kuka-500%, high umthelela amandla, ukumelana ukushaqeka okuqinile nokuhlanekezela.Ngaphansi kwezinguquko ezihlukahlukene ze-crustal ezifana nokuzamazama komhlaba kanye nokuzamazama komhlaba, ipayipi ngeke liphuke futhi linokuphepha okuphezulu.

2,Ukumelana okuphezulu nokuqhekeka kwengcindezi:ukuqina okuphezulu kwe-polyethylene PE100-RC ipayipi inokuqina okukhulu, impilo evamile yenkonzo engaphezu kweminyaka eyi-100.Uma udonga lwangaphandle lwepayipi luklwejwa ngesikhathi sokuthutha noma lwakhiwe, ukujula kokuklwebha kungaphansi kuka-20% wogqinsi lodonga, ngoba izinga lokukhula kokumelana nokuqhekeka kwalo liyingxenye eyodwa kweshumi yezinto zebanga eliphakeme le-PE100, lingaqinisekisa ngempumelelo. ukusebenza okuvamile kwepayipi nokwandisa impilo yesevisi.Ngokuhambisanayo, lapho ukujula kokuklwebha kwepayipi le-PE100 elinobukhulu obuphezulu kungaphezu kuka-10% ukujiya kodonga, akukwazi ukuhlangabezana nezidingo ezijwayelekile.

3,Ukumelana nokuklwebha:Ngenxa yokuthi ukuqina kobuso bepayipi le-PE100 -RChigh ukuqina kwe-polyethylene s kuphakeme kune-high-density PE100, ngaphansi kwesenzo sokuklwebha esifanayo, ukujula kokuklwebha kuncishiswe ngo-1/3 ~ 1/2 kunalelo lepayipi le-PE100 eliphakeme kakhulu. .

4, Ukumelana okuphezulu nomthwalo wephoyinti:Ngesikhathi sokusebenza kwepayipi, udonga lwangaphandle lucindezelwa yizinto eziqinile njengamatshe emhlabathini isikhathi eside, okwenza ukucindezeleka kwangaphakathi, okubizwa ngokuthi i-point load.Ipayipi le-polyethylene eliqinile kakhulu le-PE100-RC lingavimbela ngempumelelo ukulimala komthwalo wephoyinti, lenze ukusebenza kwepayipi kuphephe futhi kuthembeke kakhudlwana, futhi lihlangabezane ngempela nokusetshenziswa kwepayipi iminyaka engu-50.Ngesikhathi sokusebenza kwepayipi ye-PE100 ephezulu, udonga lwangaphandle lucindezelwa yizinto eziqinile ezifana namatshe isikhathi eside, okuzokwenza ukuthi udonga lwangaphakathi lwepayipi luqhume kanye nokuqhekeka kwe-brittle yendawo.

 

I-CHUANGRONG ineqembu elihle kakhulu labasebenzi elinolwazi olucebile.Uthishanhloko wawo Ubuqotho, Ubungcweti kanye Nempumelelo.Isungule ubudlelwano bebhizinisi namazwe angaphezu kwama-80 nezindawo embonini ehlobene.Njenge-United States, Chile, Guyana, United Arab Emirates, Saudi Arabia, Indonesia, Malaysia, Bangladesh, Mongolia, Russia, Africa njalonjalo.

Siyakwamukela ukuxhumana nathi ukuze uthole imininingwane yemikhiqizo kanye nesevisi yobungcweti.

    -Amapayipi akhuphukayo emithonjeni.

    Ngokuphambene namapayipi ahlanya ngensimbi noma i-ductile iron, amasistimu amapayipi e-HDPE anesisindo esilula futhi amelana nokugqwala.Inhlabathi emuncu noma amanzi “anolaka” ngeke abe nomthelela kulokho.Ukwengeza, imikhiqizo yokugqwala, evame ukukhinyabeza ukusebenza kohlelo lwamapayipi, iyagwenywa.Uma kuqhathaniswa namapayipi e-PVC, amapayipi e-HDPE avumelana nezimo futhi anikeza ukumelana nomthelela omkhulu ngisho nakumazinga okushisa ayiziro.Amapayipi angase ajwayelane kalula nesakhiwo somsele ngaphandle kokusebenzisa izixhumi ezengeziwe. Ngakolunye uhlangothi, ubungozi bokuphuka ngenxa yezimo zokuphatha ezimbi kakhulu endaweni yokwakha ziyancishiswa.Amasistimu wamapayipi e-HDPE (amajoyinti e-spigot namasokhethi) anikeza uchungechunge lwezindlela zokuxhuma zokungqubuzana kwe-longitudinal.Ngakho-ke, ukufakwa kwamahange noma ama-thrust blocks akudingekile futhi uhlelo lwamapayipi okufakazela ukuvuza okunempilo ende luqinisekisiwe.

    Ukuphuza okuphezulu kakhulu amanzi izinga.Ukufaneleka kwempahla yamanzi okuphuza kuqinisekiswa ngokuhlolwa okuzimele.Akukhona ukunambitha noma iphunga lamanzi okuphuza okuthintekayo ngenxa yokuthintana namapayipi e-HDPE.Indawo ebushelelezi kanye nokumelana nokuhuzuka okuphezulu kuqinisekisa ubuncane bediphozithi.I-polyethylene imelana nokugqwala, ngakho-ke, amanzi okuphuza awakwazi ukungcoliswa yimikhiqizo egqwalile efana nethusi noma izinsimbi ezisindayo njenge-cadmium noma umthofu, okwenzeka kaningi ngamapayipi ensimbi amadala.

     

    EzemveloIzinto ezinobungane zendawo ehlanzekile. I I-HDPE amapayipi futhi kufanelekile kukhona kuphela eyenziwe ngezinto ezihambisana nemvelo.Isibonelo, izidingo zamandla zokukhiqiza amapayipi e-HDPE ziphansi ngomphumela ovela ekukhiqizeni amapayipi enziwe nge-polyethylene.Ukusetshenziswa kwezinhlelo zamapayipi e-HDPE kunikeza isisombululo esingcono kakhulu semvelo.Isistimu yokunikeza ubufakazi bokuvuza engu-100% ingase ifakwe ngezindlela ezilula zokushisela.Ngakho, ukufaka amanzi okuphuza engozini ngezinto ezinobuthi kuyancishiswa.Ukwengeza, ukulahlekelwa kwamanzi ngenxa yezinhlelo zamapayipi avuzayo kuyagwenywa.Alukho olunye uhlelo lokunikezela olunikeza lezi zinzuzo.

    Ngoba ngokwedlulele izimo. Izinhlelo zamapayipi e-HDPE zivunyelwe ukufakwa kuzo zonke izinhlobo zenhlabathi.I-polyethylene iwukusetshenziswa okuguquguqukayo kwezindlela ezahlukahlukene zokuhlanganisa ezifaka uhlelo lokuhlinzeka ngobufakazi bokuvuza.Ngenxa yesisindo esincane kanye nezindlela ezilula zokuhlanganisa, amapayipi e-HOPE afaneleka kakhulu izimo ezingezinhle- ukufakwa endaweni enzima.

    Ukukhipha amanzi.Chuangrongamapayipi asetshenziselwa ukuthulula indle ezakhiweni ngaphansi komhlaba, izintambo zikadoti zoketshezi olubolayo futhi njengempahla efanelekile kumkhiqizi wamapayipi amakhulu abhorekile ezinhlelo zokukhucululwa kwendle. ipayipi lendle elingaphansi komhlaba kanye namapayipi emfucuza.

    Imboni.Izici ezifana nokumelana nokugqwala, ukufakwa kalula, isisindo esilula, nokuguquguquka kwenza amapayipi e-chuangrong afaneleke kumapayipi ayinkimbinkimbi ezimbonini.Alungele amakhemikhali adlayo.

    Igesi futhi Ipayipi likawoyela Amasistimu. PEamapayipi okulayinisa amapayipi ensimbi ye-carbon ukuthutha uwoyela namagesi ngomfutho ophakeme ayatholakala.Amapayipi aklanywe ngokukhethekile ngobushelelezi futhi enziwe lula ukuyifaka.Ngakho imigqa yegesi ingafakwa ngezindleko eziphansi.Lapho kubhobolwa asetshenziswa njengemigodi yokudutshulwa njengoba eshibhile.Ngenxa yezakhiwo ezinhle kakhulu ze-HDPE, ezibonisa amandla omthelela aphezulu kanye nenhlabathi enhle kakhulu enolaka. Kuhlanganiswe nokubamba nokufaka kalula, amapayipi e-HDPE angcono kakhulu izinto zokuthutha kanye nezinye izinhlobo zegesi okuhlanganisa ne-bio-gas.
