Zingaki izintambo eziku-1/2 EMT?
Ubuwazi ukuthi izintambo eziningi kakhulu ezithwele umsinga omningi zizokhiqiza ukushisa okwanele ukuncibilikisa isembozo se-vinyl, zidale ingozi yomlilo?
Ngokusho kwe-ESFI, imililo elinganiselwa ku-51,000, ukulimala okungu-1,400, kanye nomonakalo wempahla ka-$1.3 billion kwenzeka unyaka ngamunye e-US ngenxa yokusha kwezindlu. Lezi zibalo zibonisa ukuthi kufanele ufake izintambo ezifanele ukuze uvikele impahla yakho. Kungakho ngizokufundisa inombolo efanele yezintambo zama-1 EMTs esihlokweni sami.
Ngiyakukhuthaza ukuthi uqhubeke nokufunda ukuze uthole inani lezintambo ongangena kwabanye osayizi bamapayipi ekhebula:
Zingaki izintambo eziku-conduit 1/2?
Inombolo yezintambo eziqinile ezingangena epayipini elingu-½-intshi lizohlala lincike ekutheni hlobo luni lwepayipi kagesi olisebenzisayo.
Kukhona ingozi yokuthi izintambo eziningi kakhulu ngaphakathi komsele othwala umthamo omningi kakhulu zizokhiqiza ukushisa okwanele ukuncibilikisa i-vinyl enamathela ezintanjeni eziqinile, okudala ingozi enkulu yomlilo. Ukuhlonzwa okufanele kwempahla yepayipi kuyisinyathelo sokuqala sokunquma umthamo wokugcwalisa.
Uma ungeke ukwazi ukusebenzisa ikhebula le-NM ukuze uvikele izintambo zikagesi ezivelile, lesi yisikhathi osebenzisa ngaso ipayipi likagesi njengokungena esikhundleni.
Ipayipi likagesi linenani eliphezulu lezintambo zikagesi ezingahamba phakathi kwalo, noma ngabe enziwe ngensimbi eqinile (EMT), ipulasitiki eqinile (ipayipi le-PVC), noma insimbi eguqukayo (FMC). Umthamo wepayipi isilinganiso esibekwe Ikhodi Kagesi Kazwelonke futhi uthobela amakhodi amaningi endawo asebenza njengekhodi yomthetho ephakeme kakhulu kunoma iyiphi indawo.
Ukukusiza wazi ukuthi zingaki izintambo eziku-1 2 EMT, ngezansi kunethebula elivela Kukhodi Kagesi Kazwelonke ukukusiza ukuthi uzulazule:
| usayizi | Uhlobo lwepayipi | 14 awu | 12 awu | 10 awu | 8 awu |
| I-EMT | 12 | 9 | 5 | 3 | |
| 1/2 intshi | I-PVC-Sch 40 | 11 | 8 | 5 | 3 |
| I-PVC-Sch 80 | 9 | 6 | 4 | 2 | |
| FMC | 13 | 9 | 6 | 3 | |
| I-EMT | 22 | 16 | 10 | 6 | |
| 3/4 intshi | I-PVC-Sch 40 | 21 | 15 | 9 | 5 |
| I-PVC-Sch 80 | 17 | 12 | 7 | 4 | |
| FMC | 22 | 16 | 10 | 6 | |
| I-EMT | 35 | 26 | 16 | 9 | |
| 1 intshi | I-PVC-Sch 40 | 34 | 25 | 15 | 9 |
| I-PVC-Sch 80 | 28 | 20 | 13 | 7 | |
| FMC | 33 | 24 | 15 | 9 |
Yikuphi okungcono, i-EMT noma i-PVC conduit?
Ngingakusiza wenze isinqumo esinolwazi uma uphikisana phakathi kwamashubhu ensimbi kagesi namashubhu e-PVC kanye nepayipi le-EMT. I-PVC nensimbi kubiza kakhulu kunama-EMTs e-aluminium, nawo aqine kakhulu futhi ahlala isikhathi eside.
Nazi izinzuzo ezinhlanu zokusebenzisa i-EMT aluminium:
- Nakuba i-aluminium inesisindo esingama-30% ngaphansi kwensimbi, inamandla ngendlela efanayo. Insimbi ingaba brittle uma ichayeke emazingeni okushisa aphansi, kuyilapho i-aluminium iba namandla.
- I-Aluminium ingasikwa kalula, igotshwe noma igxivizwe ngaphandle kwamathuluzi akhethekile.
- I-Aluminium ivikela emisebeni kagesi, ivimbele ukuphazamiseka ezintweni zakho zikagesi ezibucayi.
- Kanye nokushisa, i-aluminium iwumqhubi omuhle kakhulu kagesi. Ihlala iphephile uma ungayithinta, kungakhathaliseki ukuthi kushisa noma kubanda kangakanani ngaphandle.
- Enye ikhwalithi ye-aluminium ukumelana nokugqwala kwayo. I-Aluminiyamu iyazivikela ngokwemvelo ngokwenza ucwecwe oluncane lwe-oxide lapho ibhekene nomoya-mpilo. Ngenxa yalokho, ayigqwali njengensimbi. Ukuze uqhubeke nokuvikela insimbi ekugqwaleni, abakhiqizi nabo bayayigcoba. (1)
Bheka ezinye zezihloko zethu ngezansi.
- Imuphi usayizi wentambo wama-amps angama-30 amafidi angama-200
- Zixhunywa kanjani izintambo zikagesi
- Uziqhuba kanjani izintambo zikagesi endaweni engaphansi engaqediwe
