Ngamanye amaxesha kukho ukubhideka malunga nokuba yintoni na iklasi ye-125 efanelekileyo - nakwishishini. Inyaniso inokukumangalisa kwaye ikugcinele imali ekugqibeleni!

Ukuba ukhe walibona ibakala le-125 lePVC lilingana, uya kuqaphela ukuba lijongeka njengesiqhelo.ibakala lama-40 elifanelekileyo. Oku akuqhelekanga. Enyanisweni, iinxalenye ze-125-grade zivela kumgca wemveliso ofanayo kunye neendawo ezibonakala zifana ne-40-grade. Ngoko ke yintoni umahluko? uvavanyo.

Ishedyuli 40 PVC ukufakwazivavanywa ngokuthe ngqo phambi kokuba ziwushiye umzi-mveliso ukuqinisekisa ukuba ziyayifezekisa yonke imigangatho aIShedyuli ye-40 ifanelekilekufuneka sidibane. Oku kunokubandakanya imigangatho ye-ASTM kunye nezinye. Nje ukuba baphumelele ezi mvavanyo, bafumana isitampu sokuvunywa seShedyuli 40.

Ufakelo lweClass 125 alulwenzi olu vavanyo. Kunoko, zithathwa ngokuthe ngqo kumgca wemveliso kwaye zithengiswa kwiibhokisi. Nangona zenziwe kusetyenziswa izinto ezifanayo kunye nobugcisa, azikho iziqwenga ze-40.

Ziza kufumaneka nini izincedisi zeNqanaba le-125? Ngokubanzi, kwimisebenzi apho ii-specs zingengomcimbi kodwa ixabiso linokubakho, sicebisa udidi lwe-125 lofakelo. Ngelixa ungaqinisekiswanga, unokufumana ukusebenza okufanayo njengokusebenzisa ishedyuli efanayo 40 isincedisi sePVC. Izincedisi zodidi lwe-125 nazo zibiza kakhulu ngaphantsi kweShedyuli 40. Zikwathande ukufumaneka kuphela kubukhulu obukhulu bedayamitha. Oku kunceda ukuphelisa iindleko zezincedisi ezihlala zibiza kakhulu.

Ngaba uyafuna ukufunda ngakumbi malunga nezincedisi zeClass 125? Sitsalele umnxeba namhlanje ukuze sixoxe ngomsebenzi wakho!

Ehlabathini lombhobho wombane, 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 kunye neengozi zemathiriyeli yecatheter nganye.

Umbhobho wesinyithi oqinileyo-Intsimbi

I-conduit yensimbi eqinile ifumaneka kwiindidi ezimbini: i-galvanized okanye i-non-galvanized. Intsimbi yeyona nto inzima kuzo zonke iintlobo zemathiriyeli yombhobho. Ngokuqhelekileyo isetyenziselwa ushishino kunye nosetyenziso lombane kwimizi-mveliso apho i-corrosion ingengomba uphambili. Inkqubo yokufaka i-galvanizing yongeza i-coating yokukhusela ye-zinc kwi-conduit yensimbi ukunceda ukuthintela ukubola. Nangona kunjalo, le ayisiyonkqubo yokusilela kwaye ukubola kuhlala kungumba. Oku kuyinyani ngakumbi kwindawo emanzi okanye ngenye indlela enomhlwa. Umbhobho wentsimbi uqinile kodwa usetyekele ekubeni nomhlwa kunye nokuwohloka.

I-EMT - Ityhubhu yentsimbi yoMbane

I-EMT yolunye uhlobo lwe-conduit yensimbi eqinile, kodwa olu hlobo lunodonga oluncinci kwaye alunayo iimpawu zamandla afana nentsimbi. Imibhobho yentsimbi yombane idla ngokwenziwa ngentsimbi okanye i-aluminiyam kwaye ayibizi kakhulu kunombhobho oqhelekileyo. Abanye oomatshini bombane bakhetha ukusebenzisa i-EMT kuba inokugotywa ukuze ilingane noyilo oluthile lwendlela yomdyarho. Nangona kunjalo, kukwathetha ukuba imibhobho intekenteke ngakumbi kwaye ithanda ukugqabhuka kuneminye imibhobho eqinile.

Umjelo wePVC

Umbhobho wePVC ukhaphukhaphu kakhulu, ngoko kulula ukuwutsala kwaye uwufake. I-PVC yimathiriyeli egqwesileyo ekwaziyo ukumelana nomhlwa kwaye ayiyi kubola kwindawo enomhlwa efana namanzi etyuwa okanye ukuvezwa kweekhemikhali. Ukungalungi kwePVC kukuba ayinaso isakhono sokumisa kwaye ingumjelo ongeyontsimbi. Ukusombulula le ngxaki, oombane basebenzisa umqhubi womhlaba owongezelelweyo kuwo wonke umjelo wePVC.

Umjelo ogqunywe yiPVC

I-PVC Coated Conduit inikezela ngeyona nto ingcono kwintsimbi eqinileyo kunye ne-PVC conduit. Imijelo egqunywe ngePVC eyenziwe ziimpawu ezifana neOcal kunye neRobroy iqala ngemibhobho yentsimbi ekrwada. Emva koko igalelwe igalvanized kwaye ifakwe imisonto. Emva koko, yogqunywe nge-polyurethane kwaye emva koko i-PVC. Ngale ndlela ufumana inzuzo yentsimbi (amandla, ubunzima, ukuqina, ukuhla) kunye neenzuzo zePVC (i-rust and corrosion protection). Umbhobho ogqunywe ngePVC wenzelwe ukujongana neziphene zezinye iindidi zemibhobho, ukubonelela ngeyona ndlela ilungileyo yokujongana nemibhobho yombane ehlala ixesha elide nengadlekiyo.
