Ipayipi elihlanganisiwe le-thermoplastics eliqiniswe ngensimbiinezici ezivamile ze-anti-corrosion, akukho ukukala, ukumelana okuphansi okushelelayo, ukugcinwa kokushisa akukho wax, ukumelana nokugqoka, isisindo esilula kanye namanye amapayipi epulasitiki, futhi isakhiwo sawo esiyingqayizivele siphinde sidale izici ezilandelayo:
(1) Ukumelana okuhle kokukhasa kanye namandla ahlala njalo emishini
Ngenxa yokuthi amapulasitiki azongena ekamelweni lokushisa nangaphansi kwengcindezi, futhi ukuphuka okuphukayo kuzokwenzeka ngaphansi kwengcindezi ehlala njalo, ukucindezeleka okuvumelekile kanye namandla okuthwala amapayipi epulasitiki ahlanzekile aphansi kakhulu (ngokuvamile ngaphakathi kwe-1.0Mpa).Amandla okusebenza ensimbi cishe aphindwe ka-10 kunawe-thermoplastics, futhi azinzile futhi awangeni phakathi kwezinga lokushisa lamapulasitiki.Lapho i-mesh steel wire frame ihlanganiswe nepulasitiki, ukukhasa kwepulasitiki kungavinjelwa ngokuphumelelayo futhi amandla ahlala njalo epulasitiki angathuthukiswa kakhulu.Ngakho-ke, ukucindezelwa okuvunyelwe kwepayipi eliyinhlanganisela ye-polyethylene enohlaka lwamathambo ocingo kuphezulu ngokuphindwe kabili kunepayipi lepulasitiki.
(2) Ukumelana okuhle kwezinga lokushisa
Amandla amashubhu epulasitiki ngokuvamile ehla ngokunyuka kwezinga lokushisa ngaphakathi kwebanga lokushisa elisetshenziswayo, futhi amandla amashubhu epulasitiki ehla ngamaphesenti angaphezu kuka-10 ngokunyuka kwezinga lokushisa ngo-10℃.Ngoba amandla wire mesh skeleton polyethylene ipayipi esiyinhlanganisela mayelana 2/3 ithwalwa wire anezikhala skeleton, ngakho amandla ayo kanye ukwanda ukusetshenziswa lokushisa futhi aphansi kunanoma yiluphi uhlobo oluhlanzekile plastic pipe.Imiphumela yokuhlolwa ikhombisa ukuthi amandla epayipi lenhlanganisela yohlaka lwentambo yensimbi ye-polyethylene ehla ngaphansi kuka-5% ngokunyuka ngo-10℃.
(3) Ukuqina, ukumelana nomthelela omuhle, ukuzinza okuhle kohlangothi, nokuguquguquka okulingene, ibhalansi eqinile nethambile
I-elastic modulus yensimbi imvamisa izikhathi ezingaba ngu-200 kune-high-density polyethylene.Ukuqina, ukumelana nomthelela kanye nokuzinza kwe-dimensional yepayipi lenhlanganisela ye-polyethylene enohlaka lwamathambo ocingo lungcono kunanoma yiliphi elinye ipayipi lepulasitiki elihlanzekile ngenxa yokuqina kohlaka lwamathambo ocingo.Ngesikhathi esifanayo, ngenxa yokuthi i-mesh metal skeleton ngokwayo iyisakhiwo esivumelana nezimo, ipayipi elihlanganisiwe libuye libe nokuguquguquka okuthile ekuqondeni kwe-axial.Ngakho-ke, ipayipi inezici zenhlanganisela eqinile futhi eguquguqukayo, ekulayisheni nasekulayishweni, ukuthutha, ukuguquguquka kokufakwa nokuthembeka kokusebenza kuhle kakhulu.Ukufakwa phansi kungasindisa inani lokusekela, izindleko eziphansi;Ukufakwa ngaphansi komhlaba kungamelana ngempumelelo nomthwalo ozumayo obangelwa ukuthomba, ukushelela kanye nezimoto.Ipayipi elincane eliwububanzi lingagotshwa kahle, libe nesakhiwo sokusiza noma isakhiwo senyoka, londoloza izifakelo zamapayipi.
(4) I-coefficient encane yokwandisa ukushisa
Ngenxa yokunwetshwa kwentambo yepayipi lepulasitiki elingu-10.6 ~ 12.2×10-6 (1/℃), i-coefficient yepayipi lepulasitiki elimsulwa lokunwetshwa kwentambo engu-170×10-6 (1/℃), ipayipi lenhlanganisela yohlaka lwentambo ye-polyethylene kunsimbi yensimbi Izingqinamba zamathambo, ukunwetshwa okushisayo kwepayipi eliyinhlanganisela kuthuthukiswa kakhulu, kuphansi kunanoma yiluphi uhlobo lwepayipi lepulasitiki elivame ukusetshenziswa, ngokuhlolwa, I-coefficient yokunwetshwa yepayipi le-wire mesh skeleton polyethylene composite ngu-35.4 ~ 35.9×10-6 (1/℃) , okuyizikhathi ezi-3 ~ 3.4 kuphela kunepayipi elivamile le-carbon steel.Imiphumela yokuhlola ibonisa ukuthi idivayisi yesinxephezelo sokushisa ngokuvamile ayidingeki ekufakweni okugqitshiwe, futhi ipayipi lingamuncwa (noma likhululwe) ngokubeka i-mendering, ngaleyo ndlela kwehlise izindleko zokulifaka.
(5) Ukuqhekeka okusheshayo ngeke kwenzeke
Ipayipi lepulasitiki elihlanzekile, ikakhulukazi ipayipi elikhulu elihlanzekile lepulasitiki elibanzi elisezingeni eliphansi lokushisa ngaphansi kwesenzo sokucindezeleka okuqhubekayo kwe-circumaxial, kulula ukukhiqiza ukuqhekeka okusheshayo okubangelwa amaphutha wendawo, ukuhlushwa kokucindezeleka (ngokuphazima kweso amakhulu amamitha kuya kumakhilomitha ngaphezulu), ngakho-ke okwamanje, i-international ngokushesha ukumelana nokuqhekeka kwepayipi lepulasitiki kubeka phambili izidingo eziphezulu, futhi insimbi ye-carbon ephansi ayikho inkinga ye-brittle fracture, Ukuba khona kwensimbi yensimbi kuvimbela ukuguquguquka nokucindezeleka kwamapulasitiki ekufinyeleleni iphuzu elibucayi lokuqhekeka ngokushesha.Ngakho-ke uma sikhuluma ngokwethiyori, akukho ukuqhekeka okusheshayo kwepayipi lenhlanganisela ye-wire mesh ye-polyethylene.
I-6) Inhlanganisela yezinto zensimbi nezepulasitiki iyunifomu futhi inokwethenjelwa
Njengamanje, ipayipi eliyinhlanganisela yensimbi-plastic emakethe ngoba indawo eyinhlanganisela phakathi kwensimbi nepulasitiki iyisixhumi esibonakalayo esiqhubekayo esijwayelekile, ukusetshenziswa kwesikhathi eside ngaphansi kwesenzo sokushintshana kokucindezeleka kulula ukuchithwa, okuholela ekuvuzeni okuhlangene, ukuncipha kwebhodlela langaphakathi, ukuvinjwa nokwehluleka.Uma kuqhathaniswa nepayipi le-wire mesh skeleton i-polyethylene eyinhlanganisela yepayipi iyisakhiwo se-mesh nge-adhesive ekhethekile encibilikayo eshisayo (i-HDPE eguquliwe) ukuze ipulasitiki ne-wire mesh kuhlanganiswe eduze futhi kuhlanganiswe.Amandla abophayo ahlanganisayo wezinto ezimbili makhulu futhi afanayo, futhi ukugxila kwengcindezi kuncane.
7) I-anticorrosion enezinhlangothi ezimbili
I-steel mesh skeleton iyinhlanganisela epulasitiki ngokusebenzisa ungqimba olukhethekile oluncibilikayo.Indawo yangaphakathi nengaphandle yepayipi inokusebenza okufanayo kwe-anticorrosive, ukumelana nokuguga, udonga lwangaphakathi olubushelelezi, ukumelana nokudlulisa okuncane, akukho scaling, akukho wax, umphumela osobala wokonga amandla, okonga kakhulu futhi olungele ukuthuthwa okungcwatshwayo kanye nemvelo egqwalayo. izimo.
(8) I-self-tracer enhle
Ngenxa yokuba khona kohlaka lwamathambo ocingo, ipayipi eliyinhlanganisela ye-wire mesh skeleton i-polyethylene ingatholakala ngendlela evamile yokubona kazibuthe, ukugwema umonakalo odalwe amanye amaphrojekthi okumba.Futhi lolu hlobo lomonakalo yipayipi lepulasitiki elihlanzekile kanye namanye amapayipi angewona ezensimbi ukukhiqiza umonakalo omkhulu.
(9) Ukulungiswa okulula nokuvumelana nezimo kwesakhiwo somkhiqizo nokusebenza
Ukwakheka nokusebenza komkhiqizo kungalungiswa ngokushintsha ububanzi bocingo, ukuhlukaniswa kwenetha, ukushuba kongqimba lwepulasitiki, ipulasitiki kanye nohlobo, ukuze kuhlangatshezwane nezidingo zokucindezela okuhlukile, izinga lokushisa nokugqwala. ukumelana.
(10) Inhlanganisela ekhethekile kagesi yokuhlanganisa, izinhlobonhlobo, ukufakwa kuyashesha kakhulu futhi kuthembekile
Ukuxhumeka kwepayipi lensimbi yensimbi enezikhala ze-polyethylene eyinhlanganisela yepayipi kusebenzisa ukuxhumana kwe-electrothermic nokuxhumeka kwe-flange.Uxhumano lwe-electrothermic ukufaka ipayipi eliyinhlanganisela kusilinganisi sepayipi le-electrothermic, futhi kufake ugesi intambo yokushisisa kagesi eshumekwe endaweni engaphakathi yokufaka ipayipi ukuze uyishisise.Okokuqala, indawo yangaphakathi yokufakwa kwepayipi iyancibilika ukuze ikhiqize ukuncibilika, futhi ukuncibilika kuyanda futhi kugcwalise igebe lokufakwa kwepayipi kuze kube yilapho indawo yangaphandle yepayipi nayo ikhiqiza ukuncibilika, futhi ukuncibilika okubili kuyancibilika ndawonye.Ngemuva kokupholisa nokubunjwa, ipayipi nokufakwa kwepayipi kuxhunywe eduze sekukonke.
