Ngamanye amaxesha kukho ukudideka malunga nokuba yintoni i-class 125 fitting - nokuba kushishino. Inyaniso inokukumangalisa kwaye ikugcinele imali ekugqibeleni!

Ukuba wakha wayibona i-PVC fitting yebanga le-125, uya kuqaphela ukuba ifana nje neqhelekileyoukufakwa kwebanga lama-40Oku akuyonto ingaqhelekanga. Enyanisweni, iinxalenye zebanga le-125 zivela kumgca ofanayo wemveliso kunye neenxalenye zebanga le-40 ezibonakala zifana. Ngoko ke yintoni umahluko? vavanyo.

Ishedyuli yama-40 yezixhobo zePVCzivavanywa ngokukodwa ngaphambi kokuba ziphume kumzi-mveliso ukuqinisekisa ukuba ziyahlangabezana nayo yonke imigangathoUkufakwa kweShedyuli 40kufuneka bahlangabezane. Oku kungabandakanya imigangatho ye-ASTM kunye neminye. Nje ukuba baphumelele ezi mvavanyo, bafumana isitampu semvume seShedyuli 40.

Izixhobo zeKlasi 125 azenzi olu vavanyo. Endaweni yoko, zithathwa ngqo kumgca wemveliso zize zithengiswe kwiibhokisi. Nangona zenziwe kusetyenziswa izixhobo ezifanayo kunye nobugcisa, azizizo iziqwenga ezingama-40 ngobuchwepheshe.

Izincedisi zeNqanaba le-125 ziya kufumaneka nini? Ngokubanzi, kwimisebenzi apho iinkcukacha zingeyongxaki kodwa ixabiso linokuba liphezulu, sicebisa izincedisi zeklasi ye-125. Nangona ungaqinisekanga, ungafumana ukusebenza okufanayo nokusebenzisa isincedisi sePVC seshedyuli ye-40. Izincedisi zeklasi ye-125 nazo zibiza ngaphantsi kakhulu kuneShedyuli ye-40. Zikwafumaneka kuphela ngobukhulu obukhulu. Oku kunceda ukunciphisa iindleko zezincedisi ezidla ngokubiza kakhulu.

Ngaba ufuna ukufunda okungakumbi ngezincedisi zeKlasi 125? Sitsalele umnxeba namhlanje ukuze sixoxe ngomsebenzi wakho!

Kwihlabathi lee-electrical conduit, kukho izinto ezininzi kunye neempawu onokukhetha kuzo. Wonke umntu unecala lakhe elihle nelibi. Kweli nqaku, siza kujonga ezinye zezona ntlobo zisetyenziswa kakhulu kwaye sidwelise izinto ezilungileyo nezingalunganga ze-catheter nganye.

Umjelo weSinyithi oqinileyo – Intsimbi

Umjelo wentsimbi eqinileyo ufumaneka kwiintlobo ezimbini: i-galvanized okanye i-non-galvanized. Intsimbi yeyona inzima kuzo zonke iintlobo zezinto ze-conduit. Ihlala isetyenziswa kwizicelo zombane zorhwebo nezoshishino apho ukugqwala kungengombandela omkhulu. Inkqubo yokwenza i-galvanizing yongeza uqweqwe olukhuselayo lwe-zinc kumjelo wentsimbi ukunceda ukuthintela ukugqwala. Nangona kunjalo, le ayisiyonkqubo ekhuselekileyo yokusilela kwaye ukugqwala kudla ngokuba yingxaki. Oku kuyinyani ngakumbi kwiindawo ezimanzi okanye ezingcolisayo. Umjelo wentsimbi uqinile kodwa usenomngcipheko wokugqwala nokuwohloka.

I-EMT - Ityhubhu yesinyithi yombane

I-EMT lolunye uhlobo lombhobho wesinyithi oqinileyo, kodwa olu hlobo luneendonga ezincinci kwaye alunazo iimpawu zokuqina ezifana nezentsimbi egayiweyo. Iipayipi zesinyithi zombane zihlala zenziwe ngentsimbi okanye i-aluminium kwaye zibiza kancinci kune-conduit eqhelekileyo. Abanye oosombane bakhetha ukusebenzisa i-EMT kuba inokugotywa ukuze ilingane noyilo oluthile lwendlela yokugijima. Nangona kunjalo, oko kuthetha ukuba iipayipi zibuthathaka kwaye zinokwaphuka ngakumbi kunezinye iipayipi eziqinileyo.

Umjelo wePVC

Umjelo wePVC ulula kakhulu, ngoko ke kulula ukuwutsala nokuwufaka. IPVC yinto ebalaseleyo ekwaziyo ukumelana nokugqwala kwaye ayizukubola kwiindawo ezingcolisayo ezifana namanzi anetyuwa okanye ukuvezwa ziikhemikhali. Ingxaki yePVC kukuba ayinawo amandla okumisa umhlaba kwaye ngumjelo ongengowesinyithi. Ukusombulula le ngxaki, iingcali zombane zisebenzisa umqhubi womhlaba owongezelelweyo kuyo yonke imijelo yePVC.

Umjelo ogqunywe yiPVC

I-PVC Coated Conduit inikezela ngeyona ndlela ilungileyo kwi-conduit yentsimbi eqinileyo kunye ne-PVC. Ii-conduit ezigqunywe yi-PVC ezenziwe ziimpawu ezifana ne-Ocal kunye ne-Robroy ziqala ngemibhobho yentsimbi eluhlaza. Emva koko iyagqunywa kwaye ifakwe intambo. Okulandelayo, igqunywa nge-polyurethane ize igqunywe nge-PVC. Ngale ndlela ufumana iingenelo zentsimbi (amandla, ubunzima, ukuqina, ukugqunywa komhlaba) kunye neengenelo ze-PVC (ukhuseleko lomhlwa kunye nokugqwala). I-conduit egqunywe yi-PVC yenzelwe ukujongana neentsilelo zezinye iintlobo ze-conduit, ibonelela ngolona khetho lubalaseleyo lwenkqubo yemibhobho yombane eqinileyo nengenamhlwa.
