Amapayipi amanzi anamuhla awavamile okwenziwe ngensimbi. Wayenenhlonipho ehloniphekile - ama-polymers ayisala kancane kancane ezindaweni eziningi. Enye yalezi zinto zokwakha i-polyethylene ephansi. Ukusuka kulokhu kwenza amapayipi amapayipi okucindezela, okungukuthi, ngamapayipi amanzi ngisho namapayipi egesi. Lolu hlobo lwezinto ezibonakalayo luya ngokuya luthandwa, njengoba ukuxhumeka kwamapayipi e-polyethylene kulula ukukwenza ngokwakho. Kuyadingeka kuphela ukubona imithetho elula kakhulu.
Lapho uhlela ukuhanjiswa kwamanzi kwangasese kwe-OHM, amashubhu e-PND avame ukusetshenziswa
Izinzuzo nezici zesicelo
Amapayipi e-polyethylene enziwe ngengcindezi ephansi ye-polyethylene. Kufunyele lokhu okuqukethwe kubhalwe njenge-PND. Inamandla aphezulu kanye nokuqina, inezakhiwo ezinhle zokusebenza:
- ukungathathi hlangothi ngamakhemikhali, kungasetshenziselwa ukuthutha ukudla;
- Izindonga ezibushelelezi zivimbela ukwakheka kwe-plaque ngaphakathi;
- hhayi ngaphansi kokugqwala;
- I-coefficie encane yokunwebeka encane icishe ibe ngu-3% ngokushisa okuphezulu (kuze kube ngu-70 ° C);
- Sisabela ngokujwayelekile ekukhulisweni kwamanzi ngaphakathi, ngenxa yokwanda kobubanzi ububanzi, nangemva kokuncipha, kuthathwa ubukhulu bokuqala.
Umzuzu owodwa wokukhumbula! Uma udinga amapayipi, ukumelana nokuqandisa (ngokwesibonelo, kudivayisi yokuhlinzekwa kwamanzi ezweni), bheka incazelo noma ukucaciswa. Akuzona zonke izinhlobo zama-copolymers, ezisetshenziselwa ukukhiqiza amapayipi, zivame ukudlulisa ukuqandisa. Ngakho-ke qaphela.
Ukungathandeki okuyinhloko kwamapayipi we-polyethylene ukulinganiselwa kwezinga lokushisa kwemvelo ethuthelwe: akufanele kube ngaphezulu kuka-40 ° C, okungukuthi, kungenzeka ukwenza umugqa wokuhambisa amanzi abandayo kusuka ku-PND, futhi, kungukuthi akunakwenzeka ukuyisebenzisa.
Amapayipi we-polyethylene tap ahlukene amadayimitha ahlukile
Elinye iphuzu: I-Polyethylene ayikubekezeleli imisebe ye-UV. Ngokuthola njalo elangeni, izinto ezibonakalayo zilahlekelwa ukuqina, futhi, ngemuva kwesikhathi esithile, ikhefu (abanye abakhiqizi benza amapayipi e-PND amelana ne-ultraviolet, kepha abiza kakhulu). Ngakho-ke, i-gasket evulekile yepayipi lamanzi kusuka kumapayipi epulasitiki ayinto engathandeki kakhulu. Kepha ukuchitha ipayipi emseleni ovela emthonjeni noma kahle endlini, yenza izintambo zamanzi abandayo azungeze indlu kungenzeka kakhulu. Lesi yisixazululo esingokomnotho futhi esivumelekile, ngoba ukufakwa nokuxhumeka kwamapayipi e-polyethylene akunzima kakhulu. Uma sikhuluma ngokuxhumeka okungabanjiswa, akukho mishini oyidingayo. Sidinga ukufakwa kuphela nezandla kuphela.

Yimaphi amapayipi epulasitiki angcono
Ngokukhiqizwa kwamapayipi amapayipi, kusetshenziswa izitembu ezimbili - re 80 noRe 100. I-polyethylene yamaselula iyiminyene kakhulu futhi ihlala isikhathi eside kunamashumi ayisishiyagalombili. Okozinhlelo zokuhlinzekwa kwamanzi zendlu yangasese yamandla we-PE 80 ngaphezulu kwanele - amelana nengcindezelo efika ku-ATM. Uma uthanda umngcele omkhulu wokuphepha, ungazithatha usuka ku-PE100. Zivame ukusebenza ku-10 ATM.
Udinga ukukhetha kuqala wabo bonke umenzi
Okufanele Ukunaka - Ezweni lapho kukhiqizwa lo mkhiqizo. Abaholi bekhwalithi bangabakhiqizi baseYurophu. Ukunemba kokusebenza kokusebenza okuphezulu kuqinisekisa ukuthembeka kohlelo oluphezulu. Ikhwalithi ephakathi nendawo nentengo yimikhankaso yaseTurkey, engxenyeni yentengo eshibhile, umenzi wesiShayina. Izinga lazo, njengenjwayelo, futhi liphansi kakhulu. Amathiphu lapha okunzima ukunikela, ngamunye ukhetha ngokubona kwawo (noma okukhona esifundeni).
Izinhlobo zokuxhunywa kwamapayipi we-PND
Ukuxhumeka kwamapayipi e-polyethylene kunezinhlobo eziningi zezinhlobo:
- okubonakalayo (ekufakweni noma ekuhlanganiseni);
- Kuhloliwe - Ukushiswa:
- Usebenzisa umshini okhethekile we-welding;
- Ukuhlanganiswa kukagesi - I-heater yakhiwa ngaphakathi kwezindawo ezimbalwa ezikhona lapho kuhlinzekwa amandla kagesi, i-polyethylene ifudumele futhi incibilikile.
I-Welding isebenza kaningi kumadayimitha amakhulu
I-Weld ngepayipi eliyinhloko lama-diameter amakhulu, asetshenziselwa ukudala amapayipi e-trunk. Amapayipi ama-mailter amancane - aze afike ku-110 mm asetshenziswa ekwakhiweni kwangasese, ingxenye enkulu ehlanganiswe nokufakwa. Izikhongso zisetshenziswa kaningi ngesikhathi sokulungisa umsebenzi, njengoba ukufakwa kwazo kuthatha isikhathi eside.
Ukufakelwa kwamapayipi we-polyethylene kukhona ukufakwa kwamapayipi (ama-tees, ama-crossmen, amakhona, ama-adaptha, ukuhlanganiswa) lapho kulungiswa khona uhlelo olufunayo. Njengoba ukuxhumana okuzimele kwamapayipi e-polyethylene kwenziwa kaningi ngosizo lokufakelwa, ake sixoxe ngabo ngemininingwane eminingi.

Isethi cishe yokufakelwa kwamapayipi wamanzi polyethylene
Yakha ekucindezelweni (ukunqenqema) ukufakwa
Ngezinhlangothi ezilinganayo noma ezimbili zokufaneleka (kwesinye isikhathi kusuka kwezintathu), kufakwa uhlelo lonke, olunikeza ukuxhumana. I-Fittal ngokwayo iqukethe:
- hull;
- ukubopha i-nut;
- I-Canggi iyindandatho epulasitiki enokugwazwa, ukuhlinzeka nge-Pipe Covice;
- izindandatho ezinenkani;
- Ama-gaskets, abhekele ukuqina.
Kuyini ukucindezelwa okulungele amapayipi e-polyethylene
Ukuxhumeka okuthembekile kangakanani
Naphezu kokungathembeki okubonakalayo, ukucindezelwa kwamapayipi e-polyethylene ekufundeni ukungcola ngokuthembekile. Kwenziwe kahle, imelana nengcindezi yokusebenza kuze kube yi-10 ATM futhi iphakeme (uma ingumkhiqizo womenzi ojwayelekile). Bukela ividiyo.Kuhle kulolu hlelo kalula ukufakwa. Cishe wayithokozela ngevidiyo. Kufakwe ipayipi nje, intambo iyahudulwa.
UDachnikov, ngaphandle kwethuba lokwenza konke ngama-URMs abo, uyakuthanda lokho, uma kunesidingo, konke kungahlakazeka, kucashe ebusika, futhi entwasahlobo futhi kuqoqa. Lokhu kunjalo uma i-wiring yenzelwe ukuchelela. Uhlelo olushaqiwe luhle futhi luhle ngoba ungahlala uqinisa ukondla noma ukubuyisela okusha. Okubi - ukufakwa kwenqwaba kanye nokubekwa kwangaphakathi endlini noma efulethini lazo akuvamile - ukubukeka akuyona into emnandi kakhulu. Kepha esizeni sokuhlinzekwa kwamanzi - ukusuka emthonjeni kuya endlini - kungcono ukuthola okuqukethwe ongakuthola.
Oda umhlangano
Ipayipi lisikwa ngokuqinile ku-90 °. Isilayidi kufanele sibe bushelelezi, ngaphandle kwe-burr. Futhi ngokungamukeleki ukuba khona kokungcola, amafutha noma okunye ukungcola. Ngaphambi kokuhlangana kusuka ekunciphisweni kwezindawo ezixhunyiwe, i-chamfer iyasuswa. Kuyadingeka ukuze umphetho obukhali we-polyethylene ungalimazi indandatho yenjoloba yokubopha.
Lapho ufaka ukuxhumana kwamapayipi e-polyethylene kuma-fittings aqophayo kuqiniswa ngesandla
Izingxenye ezisele zifakwa kwipayipi elilungiselelwe ngale ndlela: I-CRIMP nati yeluliwe, khona-ke i-Collet, ukulandela - indandatho enenkani. I-Rubber gasket Faka ezindlini ezifanele. Manje izindlu kanye nepayipi elinemininingwane esiyixhumanisa nemininingwane, amandla asetshenzisiwe - kuyadingeka ukufaka kuze kube yilapho imise. Qinisa zonke izingxenye zecala nakulo lusizo lwama-crib nuts xhuma. Ukuxhumana okuphumela kwamapayipi e-polyethylene aphonswa ngamandla ngezandla. Ukuze uthembeke, ungafinyelela ukhiye okhethekile womhlangano. Ukusetshenziswa kwamanye amathuluzi amisiwe kungathandeki: ungalimaza ipulasitiki.
I-Bendelki nobubanzi bawo
Ngaphezu kokufakwa, kunenye futhi idivaysi ethokozisayo evumela ukuthi wenze amagatsha avela kwipayipi eliqediwe. Lezi izihlalo zakudala - ukuhlanganiswa okukhethekile. Kulesi clutch kunesinye izimbobo ezihlanganisiwe noma eziningi. Imvamisa babeka i-crane, futhi igatsha elisha lokuhlinzekwa kwamanzi lixhumeke kulo.
Ama-badelles wamapayipi amanzi e-polyethylene
UCedeks ufakwa epayipi, eliboshwe ngezikulufo. Ngemuva kwalokho, egatsheni lokushayela kanye nokushayela okuminyene ngaphezulu kwepayipi, umgodi uchithwe. Lapho isilungile, kufakwa i-crane, igatsha liyaqhubeka. Ngakho-ke thuthukisa uhlelo ngemizamo emincane nezindleko.
Ama-Flange Compounds kanye noguquko ku-Metal
Kumapayipi, izakhi zohlelo ezingafakwanga intambo, futhi ukuxhumana kwe-flange kungafakwa. Lokhu kuvame ukufakwa ama-cranes noma okunye ukuvalwa okuvaliwe noma okulawula. Ukuxhuma nezinto ezinjalo kukhona ukufakwa okukhethekile kwe-PND. Ngakolunye uhlangothi, inketho yokucindezela iyindinganiso, ngakolunye - i-flange. Ukufakwa kuyinto ejwayelekile - nge-crimp nati ohlangothini olulodwa, ama-gaskets kanye nama-bolts ohlangothini lwe-flange.
I-Flange Flange Compound PND
Lapho idivaysi yokuhlinzeka ngamanzi kusuka kumapayipi e-polyethylene kungafaka nemibuzo nge-polyethylene nensimbi. Kula macala, kusetshenziswa izici, ngakolunye uhlangothi kukhona intambo. Kungaba ngaphandle noma kwangaphakathi - kuya ngohlobo lwedivayisi efakiwe noma ukuguqulwa. Ukufakelwa okunjalo kuqondile, kukhona i-angle ka-90 °.
Ukufakwa kwezinguquko nge-HDPE yensimbi
Ukufaka Okujwayelekile - Intambo (ngokufaka ubunono) ohlangothini olulodwa kanye ne-crimp nati kolunye.
