EN10253 BUTT-WELDING Umnqamlezo

I-EN 10253 umgangatho ubandakanya iintlobo ngeentlobo zofakelo lwemizi-mveliso, kubandakanya iminqamlezo ye-butt-welding, esetyenziswa kwiinkqubo zemibhobho ukuhlanganisa imibhobho kwiindlela ezininzi. Izifakelo ezinqamlezileyo zidlala indima ebalulekileyo ekuphambukeni kokuhamba okanye ukudibanisa imibhobho ngokufanelekileyo. Nantsi intshayelelo ye-EN 10253 iminqamlezo ye-butt-welding:

1.  
2. 1.EN 10253 esemgangathweni:
3. - I-EN 10253 iseka imigaqo yoyilo, imilinganiselo, imathiriyeli, ukwenziwa, kunye novavanyo lwezixhobo zokudibanisa i-butt-welding, kubandakanya iminqamlezo, ukuqinisekisa umgangatho kunye nokuhambelana kwazo kwiinkqubo zemibhobho.
4. - Umgangatho uchaza iimfuno zokuveliswa kweminqamlezo kwaye uqinisekisa ukuba bayahambelana nemigangatho yoshishino kunye nemimiselo.
5.  
6. 2. Umnqamlezo we-But-Welding:
7. -Umnqamlezo we-butt-welding yinto efanelekileyo eyilelwe enemingxuma elinganayo elinganayo kwii-engile ezichanekileyo ukuya kwenye, ngokuqhelekileyo isetyenziselwa ukukhupha ukuhamba kwamanzi kwiindlela ezininzi kwinkqubo yokubhobhoza.
8. - Iminqamlezo zizinto eziyimfuneko ezisetyenziswa kwizicelo ezahlukeneyo apho imibhobho kufuneka yahlulwe ibe ziindlela ezahlukeneyo ukulungiselela ukuhanjiswa kwamanzi.
9.  
10. 3. Izinto kunye noLwakhiwo:
11. -Iminqamlezo ye-butt-welding ehambelana nemigangatho ye-EN 10253 ifumaneka kwizinto ezahlukeneyo, kuquka i-carbon steel, insimbi engenasici, kunye nentsimbi ye-alloy, ngokusekelwe kwiimfuno ezithile zesicelo.
12. - Ezi zifakelo zenziwa kusetyenziswa iindlela zokwakha ezisemgangathweni ukuqinisekisa uqhagamshelo oluzinzileyo nolungenakuvuza xa ludityanisiwe kumbhobho.
13.  
14. 4. Isicelo kunye neeNzuzo:
15. - Iminqamlezo ye-butt-welding isetyenziswa ngokuqhelekileyo kuwo wonke amashishini afana ne-oyile negesi, i-petrochemical, i-chemical processing, kunye nezityalo zokunyanga amanzi, apho iinkqubo zemibhobho zifuna i-branching ukufezekisa ukuhanjiswa okufunwayo.
16. - Izixhobo ezinqamlezayo zibonelela ngendlela esebenzayo yokwahlula ukuqukuqela kwiindlela ezininzi, kunceda ukwandisa ulawulo lwamanzi ngaphakathi kuthungelwano lwemibhobho.
17.  
18. 5. Ufakelo kunye nokuWelding:
19. - Izenzo ezifanelekileyo zokufakela, kubandakanywa ukulungelelaniswa, ukulungiswa kwemibhobho yokuphela, kunye nobuchule be-welding, kubalulekile ekuqinisekiseni uqhagamshelo olukhuselekileyo kunye nobungqina bokuvuza xa ufaka iminqamlezo ye-butt-welding.
20. - I-Welding yindlela eqhelekileyo esetyenziselwa ukuncamathisela iminqamlezo kwimibhobho, ukudala umdibaniso oqinileyo okwaziyo ukumelana noxinzelelo, ubushushu obuguqukayo, kunye nokuhamba kwamanzi.
21.  
22. Ngamafutshane, i-EN 10253 iminqamlezo ye-butt-welding zizinto ezibalulekileyo kwiinkqubo zemibhobho, eziququzelela isebe lemibhobho kwiindlela ezininzi zokusasazwa okusebenzayo. Le minqamlezo ihambelana neemfuno ezisemgangathweni zokuqinisekisa umgangatho, ukuthembeka, kunye nokuhambelana phakathi kwezicelo zoshishino apho umbhobho kufuneka uhlukaniswe okanye udibaniswe ukulawula ukuhamba kwamanzi ngokufanelekileyo.
