EN10253 BUTT-WELDING Cross

I-EN 10253 ejwayelekile ihlanganisa ukufakwa okuhlukahlukene kwezimboni, okubandakanya iziphambano ze-butt-welding, ezisetshenziswa ezinhlelweni zamapayipi ukuhlanganisa amapayipi ezinhlangothini eziningi. Izinto ezifakwa eziphambanweni zidlala indima ebalulekile ekuchezukiseni ukugeleza noma ekuhlanganiseni amapayipi ngendlela efanele. Nasi isingeniso se-EN 10253 iziphambano ze-butt-welding:

1.  
2. 1.EN 10253 Okujwayelekile:
3. - I-TS EN 10253 ibeka imininingwane yedizayini, ubukhulu, izinsiza, ukukhiqizwa, nokuhlolwa kokufakwa kwe-butt-welding, okubandakanya iziphambano, ukuze kuqinisekiswe ikhwalithi nokuhambisana kwazo ngaphakathi kwezinhlelo zamapayipi.
4. - Izinga lisho izimfuneko zokukhiqizwa kweziphambano futhi liqinisekisa ukuthi zithobelana namazinga nemithetho yemboni.
5.  
6. 2. Isiphambano se-Butt-Welding:
7. - Isiphambano sokushisela izinqe siwukulinganisa okudizayinelwe ngezimbobo ezine ezinosayizi olinganayo kuma-engeli angakwesokudla ukuya kwelinye, ngokuvamile elisetshenziselwa ukuhlukanisa ukugeleza koketshezi kuyizikhombisi-ndlela eziningi ohlelweni lwamapayipi.
8. - Iziphambano ziyizingxenye ezibalulekile ezisetshenziswa ezinhlelweni ezihlukahlukene lapho amapayipi edinga ukuhlukaniswa abe izindlela ezihlukene ukuze kuhlangatshezwane nokusatshalaliswa kokugeleza.
9.  
10. 3. Izinto kanye Nokwakha:
11. - Iziphambano zokushisela izinqe ezihambisana nezindinganiso ze-EN 10253 zitholakala ngezinto ezihlukahlukene, okuhlanganisa i-carbon steel, insimbi engagqwali, nensimbi ye-alloy, ngokusekelwe kuzimfuneko ezithile zohlelo lokusebenza.
12. - Lokhu kufakwa kwenziwa kusetshenziswa izindlela zokwakha ezijwayelekile ukuze kuqinisekiswe ukuxhumana okuzinzile nokungavuzi lapho kushiselwe epayipini.
13.  
14. 4. Isicelo Nezinzuzo:
15. - Iziphambano zokushisela izinqe zivame ukusetshenziswa ezimbonini zonkana ezifana nowoyela negesi, i-petrochemical, ukucubungula amakhemikhali, nezindawo zokuhlanza amanzi, lapho amasistimu amapayipi edinga amagatsha ukuze kuzuzwe ukugeleza okufunekayo.
16. - Ukufakwa kwesiphambano kunikeza indlela ephumelelayo yokuhlukanisa ukugeleza kube yizikhombisi-ndlela eziningi, okusiza ukuthuthukisa ukuphathwa koketshezi ngaphakathi kwenethiwekhi yamapayipi.
17.  
18. 5. Ukufakwa kanye Nokushisela:
19. - Izinqubo zokufaka ezifanele, ezihlanganisa ukuqondanisa, ukulungisa iziphetho zamapayipi, nezindlela zokushisela, zibalulekile ekuqinisekiseni ukuxhuma okuvikelekile nokungavuzi lapho kufakwa iziphambano zokushisela izinqe.
20. - Ukushisela kuyindlela evamile esetshenziselwa ukunamathisela iziphambano emapayipini, okwenza ilunga eliqinile elikwazi ukumelana nengcindezi, izinga lokushisa eliguqukayo, nokugeleza koketshezi.
21.  
22. Kafushane, i-EN 10253 iziphambano ze-butt-welding ziyizingxenye ezibalulekile ezinhlelweni zamapayipi, ezisiza ukuhlanganisa amapayipi ezindaweni eziningi ukuze kusatshalaliswe kahle ukugeleza. Lezi ziphambano zihambisana nezidingo ezijwayelekile zokuqinisekisa ikhwalithi, ukwethembeka, nokuhambisana ngaphakathi kwezicelo zezimboni lapho umsebenzi wamapayipi udinga ukuhlukaniswa noma uhlanganiswe ukuze kulawulwe ukugeleza koketshezi ngempumelelo.
