Ngokunwetshwa okuqhubekayo kwensimu yesicelo sepayipi ye-polyethylene (PE), ipayipi le-PE liphinde libhekane nezinkinga eziningi ezilethwa izindawo ezihlukene zokusetshenziswa, njengokulimala komuhlwa embhobheni; Indlela yokuvimbela ugesi omile, umonakalo wepayipi awukwazi ukutholwa ngesikhathi sangempela, futhi ukusebenza kukonke akukwazi ukuqinisekiswa ngaphansi kwemvelo embi yokwakha; Indlela yokwengeza eminye imisebenzi emisha ekusetshenzisweni kwamapayipi epulasitiki ukuze uvumelane nemvelo entsha yokusetshenziswa idinga ukukhuthaza ukuthuthukiswa kwemboni yonke yamapayipi e-polyethylene ngokusebenzisa emisha eqhubekayo.

1. Umkhiqizo kanye nokusebenza kwepayipi elihlanganisiwe
Njengengxenye yokusebenza yokucindezela nokuthwala, ungqimba olusebenzayo lwepayipi elihlanganisiwe lidlala indima yokuvikela kanye nokusiza, futhi lingasuswa emzimbeni wepayipi lapho lisetshenziswa.
Ngokwezidingo ze-GB / T 15558.1-2015 kanye ne-GB / T 13663.2-2018, ipayipi elisebenzayo epayipini eliboshwe lizohlangabezana nezidingo zokusebenza ezichazwe kuleli zinga, njengosayizi, amandla e-hydrostatic, isikhathi sokungeniswa kwe-oxidation, ukumelana nokuhamba kancane. ukukhula
1.2 amapayipi e-PE anesendlalelo esivikelayo se-thermoplastic esixebuka esinamekwe odongeni olungaphandle
Ipayipi le-PE elinongqimba oluvikelayo lwe-thermoplastic oluxebuka olunamekwe odongeni olungaphandle (ngemuva kwalokhu olubizwa ngokuthi ipayipi elimboziwe) libhekisela epayipini elithatha ipayipi le-PE elinesendlalelo esisodwa njengepayipi elisebenzayo futhi likhiphe ungqimba oluvikelayo lwezinto ezihlukene ngaphandle kwepayipi elisebenzayo ngokusebenzisa i-multi-layer. ungqimba we-coextrusion ubuchwepheshe. Njengengxenye ye-pressure bearing and transveing ​​medium, isendlalelo esivikelayo sidlala indima yokuvikela, futhi ingxenye yechweba ingasuswa embhobho osebenzayo ngesikhathi sokushisela.
1.3 izici eziyinhloko zepayipi
eliboshwe Ipayipi elihlanganisiwe lixazulula inkinga yokuthi ipayipi le-PE kulula ukulinwaya enqubweni ye-trenchless, futhi lingavikela ngempumelelo ipayipi elisebenzayo. Ubuchwepheshe obuyinhloko ungqimba oluvikelayo. Mayelana nokusetshenziswa kwempahla eluhlaza kanye nesakhiwo, ukusetshenziswa kwe-high elastic modulus polypropylene (PP) impahla angeke nje kuthuthukise ukumelana nokuklwebheka kwesendlalelo sokuvikela, kodwa futhi kuvimbele ekuhlanganisweni nepayipi elisebenzayo futhi kube lula ukukhumula. Esigabeni sokukhiqiza, ungqimba oluvikelayo olunobude obungu-300 mm emikhawulweni yomibili yepayipi yokuvala kufanele lwenziwe lwakhiwe ngaphambili futhi lufakwe i-indent ukuze kube lula ukukhumula ungqimba oluyisivikelo ngesikhathi sokwakhiwa. Mayelana nokuvikelwa kwe-crater, ungqimba oluyisivikelo oluhlutshiwe lubuyiselwa engxenyeni ehlutshiwe ngemva kokushisela kanye nenxeba nge-fiber-reinforced tape.
1.5 Izinto ezibonakalayo zepayipi
elihlanganisiwe Ngokuqhathanisa imingcele yokusebenza evamile yezinto zokusetshenziswa ze-PE nezinto zokusetshenziswa ze-PP, amandla aqinile, i-modulus egobayo kanye nobulukhuni bezinto ze-PP ziphakeme kunalezo zezinto ze-PE. Ukumelana nokuklwebheka kwezinto ze-PP ukuthi izinto ze-PP zinzima kunezinto ze-PE.Ngakho-ke, impahla ye-PP isetshenziswa njengesendlalelo sokuvikela ukugwema ukunwaya indawo yangaphandle yepayipi yokusebenza ye-PE ekwakhiweni okungenantambo.

2. Izinzuzo zokusebenza komkhiqizo
Kumapayipi e-polyethylene asetshenziswa kakhulu ezimbonini zokuhlinzeka ngegesi namanzi, ukulimala kwamapayipi okubangelwa ukuthuthwa kwamapayipi, ukulayishwa nokulayishwa, ukwakhiwa kanye nezici zemvelo akunakugwenywa. Amapayipi ahlanganisiwe angavikela ngempumelelo amapayipi asebenzayo, axazulule ngokuhlelekile izinkinga ezihlukahlukene ezitholakala ekusebenzeni okungokoqobo ngokusebenzisa amathuluzi athile okukhuhla nezindlela zokushisela, futhi abonise izinzuzo ezilandelayo:
Vikela ipayipi elisebenzayo, unciphise ngempumelelo imihuzuko futhi uthuthukise isici sokuphepha sepayipi. Isendlalelo esingaphandle sokuzivikela singamelana ngokuphumelelayo nokuguga kweshubhu yokusebenza okubangelwa imisebe ye-ultraviolet futhi sandise isikhathi sokugcina ishubhu yokusebenza. I-coating iphinde ibe nokunwebeka, njengokwengeza i-anti-static, i-anti termite, ukubeka, ukutholwa kanye neminye imisebenzi.
3. Ukufakwa kwepayipi elinamanzi ekwakhiweni okungenazintambo
Indlela yokwakhiwa kwepayipi
Ipayipi le-CJJ 358-2018 le-polyethylene le-Trenchless Engineering (elithunyelwe ukuze ligunyazwe) lengeza imikhiqizo yamapayipi amboziwe, futhi libeka phambili izidingo zokusebenza kwempahla ye-polypropylene e peelable (PP) ungqimba oluvikelayo olunamekwe odongeni olungaphandle lobunjiniyela obungenantambo.

Ixazulula ngempumelelo inkinga yomonakalo odalwe ukuklwebheka kwetshe elingaphansi komhlaba ngesikhathi sokuthutha nokufakwa, ikakhulukazi ohlelweni lokuwela okungenantambo, futhi inikeza ithuba lokuwela okuqondile kokubhoboza ngamapayipi amakhulu kune-SDR11 Series esikhathini esizayo. Lokhu kudala amathuba nezimo zokunikeza ukudlala okugcwele ezinzuzweni ze-polyethylene (PE) kanye nokuvuselelwa nokulungiswa kwamapayipi amadala ezigabeni ezingafanelekile ukumba.

4. Isifingqo
Ipayipi eliboshwe lihlinzeka ngesixazululo esisha enkingeni yokuklwebheka kwepayipi lepayipi le-PE kwezokuthutha nokwakhiwa, ikakhulukazi ekwakhiweni okungenantambo. Ipayipi eliboshwe linezinzuzo ezinhle ekwakhiweni kwamapayipi okungenantambo. Ngokukhula kokwakhiwa kwepayipi legesi yemvelo elingenawo umsele, ipayipi elihlanganisiwe linombono obanzi wemakethe.
