Is féidir leat a bheith cinnte Píob Cruach Inslithe Teirmeach Pengfa a cheannach ónár mhonarcha. Tá an ciseal inslithe déanta as cúr polúireatán docht le dlús 60kg/m3 go 80kg/m3. Tá sé líonta go hiomlán leis an mbearna idir an píopa cruach agus an sleeve, agus tá neart nasctha áirithe aige, ionas go mbeidh an píopa cruach, an sleeve agus an ciseal inslithe ina n-iomláine soladach. Tá dea-airíonna meicniúla agus airíonna inslithe ag cúr feadán inslithe polúireatán. Athraithe go ginearálta nó comhcheangailte le hábhair inslithe eile, is féidir leis 120â agus 180â a sheasamh.
Tá fáilte romhat teacht chuig ár n-mhonarcha chun an díol is déanaí, an praghas íseal, agus an Píopa Cruach Inslithe Teirmeach Pengfa ar ardchaighdeán a cheannach. Táimid ag tnúth le comhoibriú leat. De ghnáth déantar an insliú ó ábhar poileitiléin ard-dlúis (HDPE), a bhfuil dea-airíonna teirmeacha aige agus is féidir leis teocht ard a sheasamh. Is gnách go bhfuil ciseal seachtrach an inslithe cosanta ag seaicéad déanta as cruach nó HDPE.
Ceadaíonn cruth bíseach an phíobáin é a shuiteáil go héasca faoin talamh, rud a fhágann gur rogha coitianta é do phíblínte a úsáidtear i réimsí ola agus gáis, chomh maith le córais soláthair uisce. Ar an iomlán, is rogha iontaofa agus éifeachtach é Píob Cruach Inslithe Teirmeach chun sreabhán a iompar i raon leathan tionscail, lena n-áirítear fuinneamh, mianadóireacht agus tógáil.

Is cineál píopa é Píopa Cruach Inslithe Teirmeach a úsáidtear go forleathan in iarratais tionsclaíocha agus tráchtála. Úsáidtear é go príomha le haghaidh sreabhán a iompar, mar shampla ola, gás, agus uisce, i dtionscail éagsúla, lena n-áirítear ola agus gás, próiseáil cheimiceach agus cóireáil uisce.
Próiseas táirgthe píopa cruach inslithe cúr polúireatán
Tá an Píopa Cruach Inslithe Teirmeach roinnte ina cheithre phróiseas táirgthe: modh dhá chéim, modh aon-chéim, spraeáil agus foirceannadh, agus cruach sleeve cruach:
(1) Próiseas "Dhá chéim".
Tugtar "modh píopa-i-píobáin" ar an modh dhá chéim freisin, agus is é an próiseas seo an ceann is mó a úsáidtear go forleathan. Sa mhodh seo, déantar cáithníní poileitiléin a easbhrúite ó easbhrúiteoir chun feadán cosanta seachtrach poileitiléin ard-dlúis a fháil, a chuirtear ansin ar an bhfeadán oibre, le tacaíocht ó lúibín, agus ar deireadh cúr le meaisín cúrála chun insliú polúireatán críochnaithe na Tríonóide a fhoirmiú. feadán.
(2) Próiseas "aon-chéim".
Tá an próiseas "aon-chéim" bunaithe ar chlaochlú an líne táirgeachta frith-chreimeadh PE trí-ciseal atá ann cheana féin le teicneolaíocht aibí, ionas go mbeidh an ciseal inslithe polúireatán agus an feadán cosanta seachtrach poileitiléin déanta ag aon am amháin. Is é an príomhphróiseas ná an píopa cosanta seachtrach poileitiléin a easbhrú agus an ciseal inslithe a dhoirteadh. Tá an "modh aon-chéim" de phíobán cruach inslithe theirmigh teirmeach polúireatán á thiomáint ag rollóirí V-chruthach, agus déantar an píopa cruach faoi réamhchóireáil dromchla, téamh minicíochta idirmheánach, spraeáil eapocsa, easbhrúite cosanta seachtrach poileitiléin, réitigh ciseal inslithe polúireatán, cóireáil polaraithe corónach. , próiseas cóireála deiridh píopa, etc. Tá an tiomáint sorcóir V-chruthach difriúil ón tiomáint sorcóir traidisiúnta. Gluaiseann an píopa cruach go líneach leis an sorcóir in ionad a rothlú leis féin.
(3) Próiseas "foirceannadh spraeála".
Is cineál nua próiseas é an próiseas "spraeáil agus foirceannadh", atá roinnte go príomha i pretreatment dromchla píopa cruach, spraeáil cúr polúireatán agus foirceannadh cosanta seachtrach poileitiléin. Tá an próiseas "spraeála agus foirceannadh" oiriúnach do thrastomhais píopaí éagsúla, go háirithe le haghaidh táirgeadh Píopa Cruach Inslithe Teirmeach polúireatán mór-trastomhas. Níl gá le múnlaí cúr sa phróiseas táirgthe, rud a shábhálann infheistíocht trealaimh agus a laghdaíonn déine saothair. Ina theannta sin, tá dlús cúr múnlaithe spraeála níos comhionann agus tá an strus inmheánach beag, rud a laghdaíonn tiús an fheadáin chosanta seachtrach freisin agus sábhálann sé costais.
(4) Próiseas táirgthe inslithe cruach seaicéad cruach
Cuimsíonn an Píopa Cruach Inslithe Teirmeach go ginearálta píopa istigh, píopa seachtrach agus fráma tacaíochta istigh. Tá balla seachtrach an phíobáin istigh agus balla istigh an phíobáin seachtrach ceangailte go seasta ag an bhfráma tacaíochta istigh, agus líontar an ciseal inslithe idir an píopa istigh agus an píopa seachtrach. , tá balla seachtrach an fheadáin istigh clúdaithe leis an gciseal inslithe, agus tá an lúibín istigh táthaithe go balla seachtrach an fheadáin istigh, cuirtear an feadán istigh isteach sa fheadán seachtrach ó chalafort ceann amháin den fheadán seachtrach, agus an tá lúibín istigh in aice le deireadh an fheadáin sheachtraigh ceangailte leis an bhfeadán istigh den fheadán seachtrach. Is féidir an balla a tháthú.
Tá buntáistí uiscedhíonacha agus frith-chreimeadh ag Píobán Cruach Inslithe Teirmeach, friotaíocht láidir sioc, seoltacht teirmeach beag, coigilt fuinnimh agus cosaint an chomhshaoil, agus is minic a úsáidtear iad i téamh bardasach (cuisniú), ola agus gáis, spriongaí te, geoiteirmeach, etc. trí leagan faoi thalamh nó lastuas. Tá ról tábhachtach ag iompar na meán go háirithe i bpíblínte teasa uirbeacha.
An chéad chiseal: ciseal píopa cruach oibre
De réir dearadh agus riachtanais an chustaiméara, úsáidtear píopaí cruach gan uaim, píopaí cruach bíseach agus píopaí cruach seam díreach go ginearálta. Tar éis dromchla an phíobáin chruach a chóireáil leis an bpróiseas derusting pléasctha lámhaigh chun cinn, is féidir le dímheilt an phíobáin chruach leibhéal Sa2 a bhaint amach i gcaighdeán GB8923-1988, agus is féidir le garbh an dromchla R = 12.5 miocrón a bhaint amach sa 0B6060.588 caighdeánach.
An dara sraith: teach inslithe polúireatán
Déantar é a fhoirmiú trí thuaslagán cúr polúireatán docht a instealladh isteach sa chuas a fhoirmítear idir an píopa cruach agus an truaill seachtrach le meaisín cúr ardbhrú, ar a dtugtar "cúr píopa-i-píopa" de ghnáth.
An tríú ciseal: ciseal cosanta poileitiléin ard-dlúis
Píopaí plaisteach poileitiléin dubh nó buí réamhdhéanta le tiús bhalla áirithe. Is é an fheidhm atá aige ná an ciseal inslithe polúireatán a chosaint ó mhilleadh ó rudaí crua meicniúla, agus is é an dara ceann creimeadh agus uiscedhíonach a chosc.
Úsáidtear an Píopa Cruach Inslithe Teirmeach go ginearálta mar mheán iompair, agus tá sé comhdhéanta de phíobán cruach cosanta seachtrach, frith-chreimeadh píopa cruach, ciseal inslithe agus píopa cruach oibre istigh. Tá an píopa inslithe cruach leathnaithe cruach oiriúnach chun gaile nó meáin eile a iompar faoi bhun 2.5MPa agus 350 céim Celsius. Úsáideann an chuid is mó den táirge seo píopa bíseach mar an ciseal cosanta seachtrach. Tá tréithe ard-neart aige, ní éasca le damáiste, tógáil agus cothabháil simplí, agus saol seirbhíse fada.
