HDPE Pipe: ukufakwa yezandla zabo, ikakhulukazi ukufakwa nokulaywa

Polyethylene amapayipi kukhona enemisebenzi ngenxa izici kakhulu material. Ngokwethukela kusetshenziswa kakhulu ekuphileni kwansuku zonke kuyinto HDPE ipayipi. Ukufakwa kungenziwa ngezandla zabo, uma ukwenza yonke into imithetho. Akudingi amakhono akhethekile.

izici impahla

Isidingo esikhulu HDPE ipayipi okubangelwa high impahla:

• lokushisa ububanzi - -50 ⁰ C +60 ⁰ C;
• ukumelana-esidi ane-alikhali;
• kuyaqina okusezingeni eliphezulu namandla;
• ongaphakeme conductivity ezishisayo;
• Polyethylene akuyona umbhidisi kagesi.

Ukusetshenziswa amapayipi

Ekhaya noma cottage ka HDPE amapayipi zenziwa:

• indle kanye amanzi;
• yokutholakala kwamanzi;
• igesi nezelani ekhaya;
• ikhebula isiteshi ngoba izintambo zikagesi.

Kukhethwa amashubhu

Ukuze zamanzi amapayipi ipayipi ukuthola ububanzi esingeqile 60 mm ne ukushuba udonga 4 mm. Bayobizwa lwenzelwe ingcindezi ukusebenza uketshezi ohlelweni lingaphansi kuka-1 MPA. Inzuzo iyona engekho ukugqwala zensimbi ukunambitheka kwamanzi. Uma kudingeka ukuhlomisa nokutholakala kwamanzi emithonjeni eshisayo, kubalulekile ukwazi ukuthi ezingeni lokushisa 80 ⁰ C polyethylene ithambisa naphezu eminye abaluphakamisela iqala igcwale amanzi. Kule ndaba kufanele kukhethwe, grade PE80. Ukuze amapayipi amanzi ashisayo ingaphinda azomakwa noma PE-RT PN20, bona ukumelana Ukushisa ukuze 110 ⁰ C. Ukuze lokhu izimo zokuphila kwanele.

Kufanele ukuhlukanisa amaphayiphi wamanzi ingcindezi-DRM. Ukuze izimo zokusebenza ezivamile zithathwa kunomsele bay 25 m ubude okungenani 2 mm odongeni ukujiya. Uma umugqa oyinhloko siphela ngaphansi kwengcindezi ezinhle futhi ububanzi enkulu ukudlula u 25 mm, uphuzwe njengenhlangano kampompi intshi ipayipi. Kunoma ikuphi, ukususwa kufanele kube ingxenye lincane ugesi jikelele.

Izindlela HDPE amapayipi

Ngaphambi kokufaka, ukukhetha indlela uxhumano okulandelanayo, okungase kube kanje:

1. Integral - electrofusion noma ngesidunu Welding. Egcekeni etholwe amandla efanayo ukuthi ipayipi uqobo.
2. indlela Split - ukuvuleka, kokucindezelwa futhi flange uxhumano. Okunjalo piping izinhlelo ababuthelwa kalula futhi adiliza, kungenzeka ukulungisa noma ukufakwa ezikhaleni ezihambisanayo. Ukuxhumana zenziwa nge nokufakwa.

indlela Connection kuyakhethwa kuye lezi zinto ezilandelayo:

• ipayipi diameters;
• uhlobo ukusebenza: mahhala-ukugeleza, ingcindezi, cabling;
• ukusetshenziswa valve ngezinto ezahlukene kanye diameters ezahlukene;
• ingxenye kufinyeleleke;
• khona imishini Welding.

I isikhathi eside kakhulu etholakala ashiselwe futhi ukuxhumana flanged. Isikhwama threaded ngophawu amelana ukucindezeleka. Ukufakwa HDPE amaphayiphi amanzi supply nge kokucindezelwa nokufakwa ngokuvamile kwenziwa ekhaya izingadi ukunisela izinhlelo.

Uxhumano umpofu - ukuvuleka. Zisetshenziswa kuphela non-ingcindezi amapayipi ngaphandle uma uxhumano ashiselwe.

Kokucindezela nokufakwa for HDPE amapayipi: obandayo

Ukuze HDPE amapayipi esetshenziswa nokufakwa ikakhulu plastic, kodwa kukhona ezahlukeneyo uzinze ensimbi, iron, ithusi kanye nethusi. Ahluke design futhi kungenziwa ashiselwe, threaded, nge cindezela uxhumano. Ukuze amapayipi epulasitiki kuthiwa okungcono esetshenziswa kokucindezelwa nokufakwa, lapho nenkanuko edlulele wenziwa clamping indandatho yokuhlukanisa plastic kanzima namantombazane uphawu - kokuqina izindandatho uphawu.

Njengomhlaba namanye amadivayisi yokuxhuma, kokucindezelwa nokufakwa are of nhlobonhlobo eziningana:

• elihlangana - uxhumano amapayipi ka ububanzi alinganayo futhi isiqondiso;
• inguqulelo - I-nokubopha semikhawulweni amapayipi, le diameters zazo zihlukile (ushintsho 'metal-PE ");
• sokuhoxisa engela - Kwenziwa isakhiwo twist 45-120 ^0;
• Tees, kweqa - ukudala amagatsha;
• isixhumi - kudivayisi yokuxhuma ipayipi ukuze ipayipi lamanzi;
• plug - I-uphawu ipayipi kuphelile.

Ngaphambi ewachitha amanzi kumele kuqala ukudweba umdwebo nabo bonke nokufakwa yayo valve. Leli payipi enwetshiwe ivame ukuba wring ngakho kuvikelwe abanezinto zokugawula ezibukhali noma ocindezelwe isimo enwetshiwe izinsuku 2.

Uma ekhethelwe ukufakwa HDPE ukufakwa ipayipi ngokuvamile enziwe kokucindezelwa nokufakwa.

1. Leli payipi inqanyulwa usayizi oyifunayo ithuluzi ekhethekile. Ungasebenzisa hacksaw njalo, kodwa ekupheleni esifanayo flat futhi sisusiwe burrs.
2. Hole Skena kuqondaniswe njengoba ezakheke okusaqanda akwamukeleki. chamfer sangaphandle ekupheleni.
3. ngokunembile umzimba kufaneleka ixhunywe ipayipi, ukuze singathwesi kulimaze lwezimpawu zenjoloba. Ukutshala kuyoba lula uma moisten okuhlangana kuyo.
4. Izandla some inyunyana nut. Ungasebenzisa ikhi ukunikeza ukuxhumana ezidingekile yobunzima.
5. Ukuze wesibili inqubo ipayipi iyaphindwa.

Uxhumano kokucindezelwa nokufakwa esetshenziswa sizikhandle, lapho i ukufakwa HDPE amapayipi kuleli zwe. Uhlelo kulula ukuba babuthane entwasahlobo kusayithi ahlukanisa ekwindla.

uxhumano-plug-in e izikhala ezihambisanayo alwenziwa. Kukhona elula ukusebenzisa Welding kagesi ne heater esakhelwe ngaphakathi. ipayipi Ixhunyiwe fitting 2 whereupon it icushiwe, bafudumale kwenzeka Welding ukwakha inhlangano eyodwa isiqeshana. Intengo iphakeme idivayisi, kodwa indlela kuyaphumelela futhi ngokuvamile sisetshenziswa.

Yize ukuliqaqa e kokucindezelwa Kufanele esikhundleni lwezimpawu iraba lapho ufaka. Lokhu kuzoqinisekisa enokwethenjelwa eklanywe ngokuhlakanipha ngayo.

flange ukuxhumana

Lapho ukufakwa HDPE ipayipi obandayo ukuze ububanzi 40 mm okungcono ezenziwa ngezindlela metal Flanges. Ukuze wenze lokhu, usike emaphethelweni umsiki ipayipi nge-engela ilungelo kusakhiwo esiphelele. Babe ashiselwe emikhonweni plastic ngamapulangwe, bahlela Flanges metal. Enye indlela iwukuba ahlanganise flange ipayipi kokucindezelwa ukuzizuzela bushelelezi polymer ingxenye ngokuhlanganyela. Khona-ke, i-flange abavamile, okuyinto ungenye izikhonkwane nemishudo nge ucezu efanayo ogibele ekupheleni steel pipe.

uxhumano Flanged ivumela ama-valve, nabalawuli, ama-valve futhi amapayipi phakathi kwazo.

uxhumano ashiselwe

Njengoba kungenzeka imikhiqizo metal ashiselwe HDPE ipayipi. Ukufakwa izandla siqu ukukhiqiza ngosizo imishini ekhethekile ne bafudumale electric emalungeni.

1. Usule kwalapho, futhi ulungiselela Welding imishini.
2. Setha nemingcele Welding.
3. Amapayipi awashintsheki e imihlathi umshini Welding futhi igxile. Emikhawulweni athutha kusetshenzwe.
4. Ashisayo efakwe phakathi amashubhu, okuyothi ngalo esifundeni kwancibilika.
5. Imikhawulo ingcindezi encishisiwe inakekelwa kuze lwaluyophola.
6. Inqawe kuthiwa ekhishwe Ukugunda.

Ukufakwa kubiza HDPE amapayipi nge Welding incike ubukhulu, kodwa ukubaluleka 63 mm kanti intengo efanayo ngokuvamile ruble mayelana 200. I-joint.

Lapho usebenzisa elihlangana kagesi ukufakwa izindleko ziyefana for the Welding Butt, kodwa intengo yakhe ingaphezu. Ngenxa yalokho, ukukhiqizwa izindleko mkhulu.

ukuhlolwa wokubacindezela

Operability we eqoqwe amanzi ipayipi ulithola ukugcwala amanzi 2 h. Khona-ke, ingcindezi ohlelweni ophakamayo futhi zigcinwe amaminithi angu-30. Iphayiphi is zihlolwe ukuvuza.

In the state ukusebenza ohlelweni ngokuqhubekayo elibukhali. Lapho ababebuthene kahle ke ezosebenza isikhathi eside ngokwanele.

Amaphutha ngesikhathi inhlangano HDPE amapayipi

1. Kubalulekile acabangele ukunwetshwa komugqa ipayipi emiphumeleni lokushisa. Uma uyikhohlwa, amapayipi ngaphakathi voltage ephakeme kunokuvamile, okuyinto kunciphisa ukuphila kwabo inkonzo.
2. Too enkulu ibanga phakathi anchorages kubangela nokuwohloka komsele ukuthi kuholela ekuhlulekeni yayo ngaphambi kwesikhathi.
3. Inqawe kuthiwa waqinisa kuphela ukwahlukanisa.
4. Ukuze hhayi kwakheka kwi kobuso condensate, ukusuthisa efudumele noma ezibandayo Amapayipi amakhulu amanzi aba ngci.
5. Lapho obandayo kufaneleka zezikhali ukuba ipayipi kuze kube stop oyifakile. Lapho unscrewing nut akuyona ekupheleni, bese ngokuqinile bafakwa tube isixhumi, kungaba faka ngokwanele ngokujulile. Lapho ukufakwa wenziwe HDPE amapayipi ngezandla zakhe ezweni ukunisela izinhlelo, ukuvuza akuzona njengoba eyingozi, kodwa Akwamukelekile ukuthi amanzi ukunikezela ezifuywayo. Kungakhathaliseki ukuthi imiphumela iba umuntu ezimweni zombili kubalulekile ukwenza uxhumano lwe-ezihambisanayo.
6. Over-kokuqina adaptha iholela ekubhujisweni kwabo noma pads ilele yezindawo ukufakwa.

isiphetho

Lapho ukufakwa HDPE ipayipi, ukuhlangana kwenziwa ngokuyinhloko Welding noma kokucindezelwa nokufakwa. Ngokweyame ezinhlinzekweni imithetho isethaphu yohleloxhumano kuyoba Friend futhi iqine iminyaka eminingi.
