Lokulinganisa - kuyini? Ukwahlukanisa, ukuqondisa ukukhethwa kanye nokuzikhethela

Lapho ebeka kwamanzi nokuthuthwa Ukushisa izinhlelo, qiniseka ukusebenzisa nokufakwa ethulwa namuhla okunezinhlobonhlobo esikhulu. Zisetshenziswa ukuxhuma amaphuzu kokuphenduka, ekhelini kanye ukuhwebelana. Esisemqoka izakhi Imininingwane lapho yokuxhuma amapayipi ka diameters ezahlukene. Target ISIZINDA kungenzeka idatha ye-polypropylene kwagcizelela amapayipi epulasitiki noma izinhlelo.

Ukwahlukanisa polypropylene nokufakwa

Uma kudingeka ube kufaneleka ukuthi lithathelwe ezinjalo, kumelwe wazi. Lezi zici enze kube nokwenzeka ukuba abeke uhlelo nge eside, okuvumela ukunikeza ukuhwebelana kanye ematfuba. Uma kuziwa polypropylene nokufakwa, zingase ihlukaniswa ngokweminyaka fomu. izinhlobo zezinto ezehlukene ebese ungakheka emakhoneni, phakathi kwabo kufanele ezigqanyisiwe:

• bamba;
• Area;
• tee;
• spider;
• adaptha;
• "American";
• ngalendoda;
• dlula.

Pipelines axhunyiwe nge izingcezu eliyindilinga of impahla kufanele kube okufanayo, njengoba kunjalo amashubhu. Uma uhlelo siqukethe emikhulu, ingilazi fibre kwagcizelela, nezinye izinhlobo imikhiqizo ayikwazi ukusetshenziswa.

Kungase kube nokufakwa ezidingekayo futhi polypropylene, luqiniswe ngomhlanga-fiberglass. Egcekeni izenzo njengenhlangano izihloko ngaphandle polypropylene ezisansimbi noma ezinye izinto. Kulokhu, ilungu izipikili i "American" ingasetshenziswa.

Ukwahlukanisa ngendawo

PVC nokufakwa ingahlukaniswa futhi indawo. Kule ndaba kufanele kwenziwe nokufakwa:

• Straight.
• T emise.
• Y emise.

Faka kusigaba nokufakwa angase uhlobo loxhumano, zingase ashiselwe noma kokucindezelwa. Crimp uhlobo ukusebenza kule isethi yokugcina, ngaphezu ukuqoqa ke akudingekile. Uma sithola ukufana phakathi kwakhe ngokuhlanganyela yayo eziphothene, owokuqala inebuhle. Njengoba izinzuzo ezinkulu yilezi:

• lula ukufakwa;
• asikho isidingo Welding;
• ikhono ukufaka zonke izimo zezulu, njengoba crimping kwe-polypropylene nokufakwa asesabi umnkantsha okushisa;
• ukungabi namakhono adingekayo ukuze ukuqoqwa kokucindezelwa nokufakwa.

Indlela ukukhetha nokufakwa ashiselwe yokuxhuma

Ngo uhla enkulu emakethe namuhla emelelwa efanelekayo. Yini nalapho ukusebenzisa lesi sici, ungakwazi ukubona uma ufunda isihloko. Ekhuluma ewukuhlakanipha okwenziwe omunye kakhulu elula izenzo elihlangana nokufakwa, okuyilona elidingekayo ukuze uxhume amachopho amabili iphayiphi. Ingasetshenziselwa kwabashiselayo futhi ezivamile amapayipi nakakhulu.

Le misebenzi yenziwa push-kufanelekile. Kodwa phakathi nokufakwa bungabonakala ngisho emakhoneni, abaqoqi, futhi Tees. Lapho ekhetha tee kumelwe banake yokuthi kungase inguquko noma elula. Esimweni sokuqala, ungenza kwathatha ububanzi ezahlukene.

Ukuze uthole amanye amathiphu ngokukhetha

Lapho egijima kushisa noma kubanda amanzi, ngalendoda kufanele kukhethwe, angasetshenziswa ukuxhuma abaqoqi amaningi umthombo ukushisa. Ngezinye izikhathi kulekelelwa ibhola valve, okuyinto zivikela ukugqwala.

Lapho handyman idinga kufaneleka ukuthi nokuthi iziphi izinhlobo icala, kumelwe ukuthi nakanjani nazi. Ngokwesibonelo, ukwedlulisela komsele 90 isidingo ° ekhoneni. Welding wayo wenziwa izisekelo, lezi ucwaningo lusikisela Ukushisa izakhi kanye uxhumano yabo ngokufaka kolunye.

nokufakwa Ukwahlukanisa steel

Steel nokufakwa ingahlukaniswa ngokwenjongo, tiniketwe:

• couplings;
• Tees;
• nokufakwa kwayo;
• adapters;
• Imigudu.

kungenziwa endaweni ngokusebenzisa kwawo labizwa ngokuthi Lesisemkhatsini yokuxhuma. Uma sikhuluma isidingo ukuxhuma amapayipi we ubukhulu efanayo, kufanele usebenzise ISIZINDA ngqo, kungenjalo udinga Thenga kakhulu imininingwane inguquko. Sinenkosi uxhumano threaded.

Njengoba indlela ngokujoyina nokufakwa steel kufanele ihlukaniswe yaba:

• kokucindezelwa;
• cindezela nokufakwa kwayo;
• Push-nokufakwa kwayo;
• crimp;
• threaded.

Uma udinga fitting yini lo mklamo nakanjani kungatholakala. Ngokwesibonelo, indlela ezivamile ngokuhlanganisa izakhi aphume ashone threaded izingxenye. Kodwa kokucindezelwa nokufakwa namuhla ethandwa kakhulu ngoba kulula ukufaka. Zingasetshenziswa yokuxhuma amapayipi ngezinto ezahlukene. ngendlela Anhlobonhlobo kukhona nokufakwa Axial, angasetshenziswa yezinhlobo ezahlukene ipayipi.

Imiyalelo okukhetha nokufakwa threaded

nokufakwa Threaded tingentiwa ngezinto ezahlukene. Uma kuwukuthi zethusi, bese ngaphambi izinto namuhla ezivamile. Ukuba khona iringi clamping inikeza uphawu iyiphi kwakwakhe. Uma ufuna ukufeza izakhiwo anti-ukugqwala, kubalulekile ukukhetha nokufakwa nge enamathela ukuthi kuyadingeka lapho esebenzelana nesizwe amapayipi ngezinye izikhathi.

Uma ufuna ukuthenga into ngemali engambi eqolo, kufanele uthanda nokufakwa zethusi. Ababona kuncike nokugqwala futhi ukwazi ukusebenza isikhathi eside. Uma ufuna ukushintsha isiqondiso motion medium iphayiphi, kubalulekile ukuthola umdlalo threaded nokufakwa. Kodwa ukudala ukugeleza ngokwahlukana iphuzu tee eziningana kungenzeka ayethanda.

Uma kudingeka, ukudala uxhumano amapayipi ezimbili zibe uhlelo olulodwa kufanele usebenzise bamba, element ngokuphelele efanelekayo ilungiselelo iphayiphi ngezinto ezahlukene. Kulokhu, uzokwazi ukuxhuma ipayipi plastic zethusi. Nokufaka i-amapayipi zethusi kungabuye ezenziwe impahla efanayo. Ngokwesibonelo, i-plug kungaba sealingly ukuvala uhlelo futhi uvimbele ukuphela ipayipi. Ngezinye izikhathi le ngxenye is hhayi kuphela esetshenziswa njengoba izingxenye ukusebenza, kodwa futhi a element zokuhlobisa.

Ukukhetha nokufakwa for amapayipi ithusi, kufanele ayethanda kulabo abenziwe ukwaziswa okufanayo, ngoba kukhona isikhathi eside kakhulu, kulula ukufaka futhi eqotho. Ukuze uthuthukise izici elingenamikhono zabo izinto ezikhethekile, phakathi kwabo:

• nickel;
• -chrome;
• zinc.

Amanani nokufakwa

Amanani PVC nokufakwa ngeke ifane kuye element uya khona. Ngokwesibonelo, ingcina "American" izobiza 119 deda., Ngenkathi ingcina engasindi "American" kubiza ruble 105. Isikhwama ingcina kunciphisa nezindleko ruble 16, kodwa i-plug -. Ruble 13.

Uma udinga nokufakwa PVC, ngentengo yabo kufanele ube nesithakazelo. Ngokwesibonelo, ngalendoda kuyoba ezibizayo, nezindleko kuyinto ruble 804., Kodwa esiphambanweni kuwufanele ruble 91. I elihlangana ingcina izobiza ruble 16. Phansi-ingcina bushing kubiza ruble 33. nokufakwa Plastic namuhla in ezahlukahlukene, phakathi kokunye, kufanele kwenziwe ukunciphisa tee, intengo salo ruble 37. Engela 90 ° kubiza RUB 9 kuphela. yileyo naleyo ingamashekeli.
