2. Iindidi ezahlukeneyo zemibhobho yentsimbi emnyama

Ngokweenkqubo ezahlukeneyo zemveliso, imibhobho yentsimbi emnyama yahlulwe ngokubanzi yaba yimibhobho yentsimbi edityanisiweyo kunye nemibhobho yentsimbi engenamthungo.

Umbhobho weNsimbi eWelding:Umbhobho wentsimbi odibeneyo wenziwa ngokuwelda iipleyiti zentsimbi okanye imicu eqengqelekayo kwityhubhu. Ikwaziwa ngokuba yipayipi ye-ERW (Electric Resistance Welded). Olu hlobo lombhobho ludla ngokuba namandla kwaye luqine kakuhle. Inkqubo yokuvelisa umbhobho wentsimbi odibeneyo ilula kakhulu, kwaye inokuvelisa amacandelo amade ombhobho ngexabiso eliphantsi.

Umbhobho weNtsimbi ongenamthungo:Umbhobho wentsimbi ongenamthungo wenziwa ngenkqubo yokuqengqeleka eshushu okanye ebandayo ngaphandle kwemithungo edibeneyo. Olu hlobo lombhobho lunamandla aphezulu kwaye lukhuselekile phantsi koxinzelelo oluphezulu kunye neemeko ezinzima kuba alunazo iindawo ezibuthathaka (ezifana nemithungo).

3. Yintoni ipayipi yentsimbi emnyama?

Umbhobho omnyama usetyenziswa kakhulu kwizicelo ezahlukeneyo, kubandakanya imibhobho yamanzi, ukusasazwa kwegesi, kunye nenkxaso yesakhiwo.

Umbhobho wentsimbi ongenamthungoyenziwe ngaphandle kwemithungo okanye ii-welds, nto leyo eyomeleza amandla ayo kwaye yenze ukuba ibe lukhetho olukhuselekileyo lokuthutha iigesi kunye nolwelo phantsi koxinzelelo oluphezulu. Olu hlobo lombhobho luxatyiswa ngakumbi kwiindawo apho ukuqina kwesakhiwo kubaluleke kakhulu, njengakwimibhobho yeoyile negesi.
Kwelinye icala,umbhobho wentsimbi emnyama edityanisiweyoIsetyenziswa kakhulu kwiindlela ezahlukeneyo zokusebenza, kuquka imibhobho yamanzi, uthumelo lwegesi kunye neenkqubo zokutshiza umlilo. Iimpawu zayo zokumelana nomlilo zenza ukuba ifaneleke kwiinkqubo ezinjalo, apho ukuthembeka nokhuseleko kubaluleke kakhulu.

4. Ulawulo loMgangatho kunye nokuHanjiswa kweeMibhobho eziMnyama

1) Ngexesha nasemva kwemveliso, abasebenzi be-QC abanamava angaphezu kweminyaka emi-5 bahlola iimveliso ngokungacwangciswanga.
2) Ilabhoratri evunyiweyo yesizwe eneziqinisekiso ze-CNAS
3) Uhlolo olwamkelekileyo oluvela kumntu wesithathu oqeshwe/ohlawulwe ngumthengi, ofana ne-SGS, i-BV.
4) Ivunyiwe yiMalaysia, iIndonesia, iSingapore, iiPhilippines, iOstreliya, iPeru kunye ne-UK. Sinezatifikethi ze-UL /FM, ISO9001/18001, kunye ne-FPC.
