Ubhekene noxhumo lwe-PVC elingu-2-intshi? Indlela engalungile ingabangela ukuvuza okukhungathekisayo kanye nokwehluleka kwephrojekthi. Ukuthola ukujoyina zisuka nje kubalulekile ohlelweni oluvikelekile, oluhlala njalo.

Ukuze uxhume amapayipi amabili e-PVC angu-2 intshi, sebenzisa ukuhlanganisa kwe-PVC okungu-2-intshi. Hlanza futhi uqalise kokubili iziphetho zamapayipi kanye nengaphakathi le-coupling, bese usebenzisa usimende we-PVC. Phusha ipayipi ngokuqinile ekuhlanganiseni ngokujika kwekota bese ubamba imizuzwana engu-30.

Ngikhumbula ngixoxa no-Budi, umphathi wokuthenga womunye wozakwethu abakhulu e-Indonesia. Ungishayele ucingo ngoba usonkontileka omusha ayemphakele wayenezinkinga ezinkulu naye
amalunga avuzayokuphrojekthi enkulu yokunisela. Usonkontileka ufunge wagomela ukuthi wayezilandela lezi zinyathelo, kodwa ukuxhuma kwakungeke kubambe ngaphansi kwengcindezi. Lapho sihamba ngenqubo yakhe, sathola ucezu olwalungekho: wayenganikezi ipayipi lokhoi-twist yokugcina yekotanjengoba ewuphushela emthanjeni. Kuyimininingwane encane kangako, kepha lokho kusonta yikho okuqinisekisa ukuthi usimende we-solvent usakazeka ngokulinganayo, udale i-weld ephelele, eqinile. Kube yisifundo esihle eqenjini lakhe ukuthi ibaluleke kangakanani indlela efanele. Ngisho nezinto ezinhle kakhulu, "indlela" iyikho konke.

Ungawaxhuma kanjani amasayizi amabili ahlukene we-PVC?

Udinga ukujoyina ipayipi elikhulu kwelincane? Ukufakwa okungalungile kudala ibhodlela noma indawo ebuthaka. Ukusebenzisa i-adaptha efanele kubalulekile ukuze kube noguquko olubushelelezi, oluthembekile.

Ukuxhuma amasayizi ahlukene wepayipi le-PVC, kufanele usebenzise i-reducer bushing noma i-coupling yokunciphisa. I-bushing ilingana ngaphakathi kokuhlangana okujwayelekile, kuyilapho ukuhlanganisa okuncishisiwe kuxhuma ngokuqondile osayizi ababili abahlukene bamapayipi. Kokubili kudinga indlela evamile yokuqalisa kanye nosimende.

Ukukhetha phakathi kuka-ai-reducer bushingkanye aukuhlanganiswa kokunciphisakuncike esimweni sakho esithile. I-reducer coupling iwukulinganisa okukodwa okunokuvuleka okukhulu ekugcineni kwelinye kanye nokuncane ngakolunye. Kuyisixazululo esihlanzekile, esiyisiqephu esisodwa sokuxhuma, ake sithi, ipayipi elingamayintshi angu-2 ngqo epayipini elingu-1.5 intshi. Ngakolunye uhlangothi, ai-reducer bushingyakhelwe ukuthi ingene ngaphakathi kokulingana okujwayelekile okukhudlwana. Isibonelo, uma unokuhlanganisa okungu-2 intshi, ungafaka "2-inch by 1.5-inch" bushing endaweni eyodwa. Lokhu kuguqula ukuhlanganisa kwakho okujwayelekile okungu-2 intshi kube isinciphisi. Lokhu kuyasiza kakhulu uma usuvele unokufakwa okujwayelekile esandleni futhi udinga nje ukulungisa uxhumano olulodwa. Ngihlale ngeluleka uBudi ukuthi azigcine zombili, njengoba osonkontileka bejabulela ukuba nezinketho esizeni somsebenzi.

Ungawajoyina kanjani ama-PVC amabili?

Unamapayipi nokufakwa, kodwa awuzethembi inqubo yokunamathisela. Ilunga elivuzayo lingonakalisa umsebenzi wakho onzima. Ukwazi indlela efanele yokushisela i-solvent akuxoxiswana ngayo.

Ukuhlanganisa amapayipi amabili e-PVC kuhilela inqubo yamakhemikhali ebizwa ngokuthi i-solvent welding. Udinga okokuhlanza/i-primer ukuze ulungise ipulasitiki ne-PVC usimende ukuze uncibilike futhi uhlanganise izindawo ezingaphezulu. Izinyathelo ezibalulekile yilezi: ukusika, ukususa, ukuhlanzeka, i-prime, usimende, bese uxhuma nge-twist.

Inqubo yokujoyina i-PVC inembile, kodwa ayinzima. Kumayelana nokulandela zonke izinyathelo. Okokuqala, sika ipayipi lakho ngokulinganayo ngangokunokwenzeka usebenzisa i-PVC cutter. Ukusikwa okuhlanzekile kuqinisekisa ukuthi amapayipi aphuma kahle ngaphakathi kwendawo efanelekile. Olandelayo,deburr ngaphakathi nangaphandle konqenqema olusikiwe. Noma yimaphi ama-burrs amancane angakhuhla usimende futhi bonakalise uphawu. Ngemuva kokulinganisa okusheshayo okumile ukuze uhlole izilinganiso zakho, yisikhathi sengxenye ebalulekile. Faka isiceloi-purple primerngaphandle kwepayipi kanye nengaphakathi lokufafaza. I-Primer ayiyona nje into yokuhlanza; iqala ithambe ipulasitiki. Ungayeqi. Ngokushesha landela ngongqimba oluncane lukasimende lwe-PVC kuzo zombili izindawo. Phusha ipayipi kufitting ngekota-turn twist ize ime. Ibambe iqine imizuzwana engu-30 ukuvimbela ipayipi ukuthi lihlehle liphume.

Isikhathi sokwelashwa sibalulekile. Ungalihloli ilunga ngokucindezela kuze kube yilapho usimende uqina ngokugcwele. Lesi sikhathi siyahlukahluka nezinga lokushisa.

Indlela yokuxhuma amapayipi amabili ama-diameter ahlukene?

Ukuxhuma amapayipi anosayizi abahlukene kubonakala kukhohlisayo. Uxhumo olubuthakathaka lungabangela ukuvuza noma lukhawulele ukugeleza. Ukusebenzisa ukulingana okulungile kwenza uguquko lube lula, luqine, futhi lusebenze kahle kunoma iyiphi isistimu.

Ukuze uxhume amapayipi amadayamitha ahlukene, sebenzisa isilinganisi esithile soguquko njengesixhumi esinciphisayo. Ukuze uthole izinto ezahlukene, njenge-PVC ukuya kwithusi, udinga i-adaptha ekhethekile, njenge-adaptha yesilisa ye-PVC exhunywe ekufakweni kwethusi elinentambo yowesifazane.

Ukuxhuma amapayipi kumayelana nokuba “nebhuloho” elifanele phakathi kwawo. Uma uhlala nento efanayo, njenge-PVC, ukuhlanganisa okuncishisiwe ibhuloho eliqondile phakathi kwamadayamitha amabili ahlukene. Kodwa kuthiwani uma udinga ukuxhuma i-PVC kwipayipi yensimbi? Kulapho udinga uhlobo oluhlukile lwebhuloho:
ama-adaptha anemicu. Ungashisela i-adaptha ye-PVC enezintambo zesilisa noma zesifazane kwipayipi lakho le-PVC. Lokhu kukunikeza isiphetho esinentambo ongakwazi ukukuxhuma ekufakweni kwensimbi okuhambisanayo. Iwulimi lomhlaba wonke lokuxhuma izinto zamapayipi ahlukene. Isihluthulelo siwukuba ungalokothi uzame ukunamathisela i-PVC ngqo ensimbi. Ngeke kusebenze. Uxhumano oluluchungechunge luwukuphela kwendlela evikelekile. Lapho wenza lokhu kuxhumana, sebenzisa njaloItheyiphu ye-PTFE (i-Teflon tape)emiculweni yesilisa ukusiza ukuvala ilunga nokuvikela ukuvuza.

Imuphi usayizi wokuhlanganisa we-PVC engu-2 intshi?

Unepayipi le-PVC lama-intshi angu-2, kodwa yimuphi usayizi ofanele? Ukuthenga ingxenye engalungile kumosha isikhathi nemali. Ukuhlanganiswa kokulinganisa kokufakwa kwe-PVC kulula uma usuwazi umthetho.

Ukuze uthole ipayipi le-PVC lama-intshi angu-2, udinga ukuhlanganisa kwe-PVC okungu-2-intshi. Ukufakwa kwe-PVC kuqanjwe ngokususelwe kusayizi wepayipi okuzisholo axhumeka kuwo. Ububanzi bangaphandle bepayipi bukhulu kunamayintshi angu-2, kodwa uhlale ufanisa ipayipi elithi “2 intshi” nokulingana “kwamayintshi angu-2”.

Leli elinye lamaphuzu ajwayeleke kakhulu okudideka engisiza abathengisi abasha be-Budi baqonde. Banamakhasimende akala ingaphandle lepayipi labo elingu-2-intshi, bathole ukuthi licishe libe amayintshi angu-2.4, bese libheka elilingana naleso silinganiso. Kuyiphutha elinengqondo, kodwa akusiyo indlela ukulinganisa kwe-PVC okusebenza ngayo. Ilebula elithi "2-inch" yigama lokuhweba, elaziwa ngokuthiUsayizi Wepayipi Lokuqamba (NPS). Kuyindinganiso eqinisekisa ukuthi ipayipi lanoma yimuphi umkhiqizi elingu-2-intshi lizolingana nanoma yikuphi ukulingana okungamayintshi angu-2 komkhiqizi. Njengomkhiqizi, sakha ukufakwa kwethu ngale ndlela enembileIzindinganiso ze-ASTM. Lokhu kuqinisekisa ukusebenzisana futhi kwenza izinto zibe lula kumsebenzisi wokugcina: vele ufanise nosayizi wegama. Ungalethi irula esitolo sehardware; vele ubheke inombolo ephrintiwe epayipini bese uthengela ukufakwa ngenombolo efanayo.

Isiphetho

Ukuxhuma i-PVC engu-2-intshi kulula ngokuhlanganisa okungu-2-intshi nokushisela kwe-solvent efanele. Ngosayizi abahlukene noma izinto zokwakha, sebenzisa njalo isixhumi esilungile noma i-adaptha ukuze uthole umsebenzi ongavuzi.
