Usayizi olinganayo
i-pvc ipayipi kasayizi we-chard id od ngaphakathi kodayamitha ngaphandle kwedayamitha Njengoba kushiwo kubhulogi elidlule lepayipi le-PVC elingaphandle kobubanzi, ipayipi le-PVC nokufakwayo kunosayizi ojwayelekile kusetshenziswa isistimu yegama.Ngale ndlela, zonke izingxenye ezinosayizi ofanayo egameni zizohambisana.Isibonelo, konke ukufakwa okungu-1″ kuzongena kupayipi elingu-1″.Lokhu kubonakala kulula ngokwanele, akunjalo?Nokho, nansi ingxenye edidayo: Ububanzi bangaphandle (OD) bepayipi le-PVC bukhulu kunosayizi osegameni lalo.Lokhu kusho ukuthi ipayipi le-PVC elingu-intshi elingu-1 linobubanzi obungaphandle obungaphezu kweyintshi elingu-1, futhi okokufakwa kwe-PVC okuyiyintshi engu-1 kunobubanzi obungaphandle obukhudlwana kunepayipi.

Into ebaluleke kakhulu lapho usebenza namapayipi e-PVC nokufakwa ubukhulu begama.1″ ukufakwa kuzofakwa kupayipi elingu-1″, kungaba iSheduli 40 noma engu-80. Ngakho-ke, nakuba isokhethi engu-1″ inombobo obanzi kuno-1″, izongena epayipini elingu-1″ ngoba ububanzi bangaphandle balelo payipi futhi inkulu kuno-1″.

Ngezinye izikhathi ungase ufune ukusebenzisa okokufaka kwe-PVC ngamapayipi angewona awe-PVC.Kulesi simo, ubukhulu begama abubalulekile njengobubanzi bangaphandle bepayipi oyisebenzisayo.Ziyahambisana inqobo nje uma ububanzi bangaphandle bepayipi bufana nobubanzi bangaphakathi (ID) bokulinganisa elingena kukho.Nokho, 1″ ukufakwa kanye 1″ carbon steel amapayipi angase angahambisani ngoba anosayizi ofanayo.Yenza ucwaningo lwakho ngaso sonke isikhathi ngaphambi kokusebenzisa imali ezingxenyeni ezingase zingahambisani!

Izinhlobo Zokuphela ze-PVC kanye Nezinamathiselo
Ngaphandle kwanoma yikuphi okunamathelayo, ipayipi le-PVC nokufakwa kuzobanjwa ndawonye kuqine kakhulu.Nokho, ngeke bavimbe amanzi.Uma uzodlula noma yiluphi uketshezi emapayipini akho, udinga ukuqinisekisa ukuthi akukho ukuvuza.Kunezindlela ezimbalwa ezihlukene zokwenza lokhu, futhi indlela oyikhethayo izoncika ekutheni uxhumanisa nani.

Amapayipi e-PVCngokwazo ngokuvamile azinazo iziphetho ezinentambo.Lesi ngesinye sezizathu zokuthi kungani ukufakwa okuningi kwe-PVC kuneziphetho ezishelelayo.“Isilayidi” ku-PVC akusho ukuthi uxhumano luzoshelela, kusho ukuthi okokufaka kuzoshelela phakathi kwepayipi.Lapho ipayipi lifakwa endaweni ehlangene ye-slip, ukuxhumana kungase kubonakale kuqinile, kodwa ukuze kudluliselwe noma iyiphi i-liquid medium, idinga ukuvalwa.Usimende we-PVC uvala ipayipi ngokuhlanganisa ngamakhemikhali ingxenye yepayipi kwenye ingxenye yepulasitiki.Ukuze ugcine okokufaka okuslayidayo kuvaliwe, uzodinga iprimer ye-PVC kanye nosimende we-PVC.I-Primer ithambisa ingaphakathi le-fitting ukulungiselela ukunamathiswa, kuyilapho usimende ugcina izingcezu ezimbili zihlangene.

Ukufakwa okunemicu kudinga ukuvalwa ngokuhlukile.Isizathu esikhulu esenza abantu basebenzise izingxenye ezinentambo ukuthi zingahlukaniswa uma kunesidingo.I-PVC Cement ihlanganisa amapayipi ndawonye, ​​ngakho-ke uma isetshenziswa ekuhlanganyeleni okuhlanganisiwe, izokwakha uphawu, kodwa izintambo ngeke zisebenzise.Indlela enhle yokuvala amalunga anentambo futhi uwagcine esebenza ukusebenzisa itheyiphu yokuvala intambo ye-PTFE.Vele uyisonge ngentambo yesilisa izikhathi ezimbalwa futhi izogcina uxhumano luvaliwe futhi lugcotshiwe.Izinto ezifakwayo zisengakhululwa uma ufuna ukubuyela kulelo lungu ukuze lilungiswe.

Ingabe ufuna ukufunda ngazo zonke izinhlobo ezahlukene ze-PVC nokuxhumana?Chofoza lapha ukuze ufunde kabanzi mayelana nezinhlobo zokugcina ze-PVC.

Ukufakwa kwebanga lefenisha nokufakwa okuvamile
Amakhasimende ethu avame ukusibuza, “Uyini umehluko phakathi kwezifakelo zebanga lefenisha nokufakwa okuvamile?”Impendulo ilula: okokufakwa kwethu kwefenisha akunawo amaphrinti omkhiqizi noma amabhakhodi.Ahlanzekile amhlophe noma amnyama angaphrintiwe lutho.Lokhu kubenza balungele izinhlelo zokusebenza lapho amapayipi abonakala khona, kungakhathaliseki ukuthi empeleni asetshenziselwa ifenisha noma cha.Ubukhulu buyafana nezesekeli ezijwayelekile.Isibonelo, kokubili ukufakwa kwebanga lefenisha okungu-1″ kanye no-1″ okuvamile kungafakwa kupayipi elingu-1″.Futhi, ziqinile njengezinye izinto zethu zokufakwa kwe-PVC.

Chofoza lapha ukuze ufunde kabanzi mayelana namapayipi ethu ebanga lefenisha nokufakwa.

Ukufakwa kwepayipi le-PVC– Incazelo kanye nezicelo
Ngezansi kunohlu lwezinye izesekeli ezisetshenziswa kakhulu ze-PVC.Ukufakwa ngakunye kuqukethe incazelo yesesekeli kanye nokusetshenziswa kwayo okungenzeka kanye nezicelo.Ukuze uthole ulwazi olwengeziwe ngalezi zinsiza, vakashela amakhasi azo afanele womkhiqizo.Kubalulekile ukukhumbula ukuthi zonke izinto ezisetshenziswayo zinokuphindaphinda nokusetshenziswa okungenakubalwa, ngakho-ke gcina lokho engqondweni lapho uthenga izisetshenziswa.

Ithi
A Isikhwama se-PVCiyinhlanganisela yamatheminali amathathu;amabili emugqeni oqondile futhi eyodwa ohlangothini, nge-engeli engama-degree angama-90.I-Tee ivumela umugqa ukuthi uhlukaniswe ube imigqa emibili ehlukene enoxhumano lwe-90 degree.Ngaphezu kwalokho, i-tee ingaxhuma izintambo ezimbili zibe yintambo eyodwa enkulu.Zibuye zisetshenziswe njalo ekwakhiweni kwe-PVC.I-Tee iyinhlanganisela eguquguqukayo kakhulu futhi ingenye yezingxenye ezisetshenziswa kakhulu ekufakweni kwamapayipi.Ama-tee amaningi aneziphetho zesokhethi ezishelelayo, kodwa izinguqulo ezinentambo ziyatholakala.
