Iimfuno zobugcisa zeetyhubhu zentsimbi ye-carbon ezifakwe kwi-hot-dip
| Iinkcukacha zobugcisa | |
| • Izinto ezisetyenziswayo | Intsimbi yekhabhoni eshushu edityiweyo; |
| • Ukwaleka | Umaleko weZinc usetyenziswa kusetyenziswa inkqubo yokutshisa i-galvanizing, enobukhulu obuncinci ngokuhambelana nemigangatho efanelekileyo; |
| • Ubude | Iibhari ukusuka kwi-5.8 ukuya kwi-6 yeemitha (okanye njengoko kufuneka yiprojekthi) |
| • Ubukhulu bodonga | Ngokwemigangatho ye-NBR, i-ASTM okanye i-DIN esebenzayo; |
| Imigangatho neMimiselo | |
| • I-NBR 5580 | Iityhubhu zentsimbi yekhabhoni ezigayiweyo ezinee-seams okanye ezingenazo zokuhambisa ulwelo; |
| • I-ASTM A53 / A53M | Ingcaciso esemgangathweni yePipe, iSteel, emnyama neshushu, egqunywe ngeZinc, eWelded kwaye engenamthungo; |
| • I-DIN 2440 | Iityhubhu zentsimbi, zinobunzima obuphakathi, zifanelekile ukukrufulwa |
| • BS 1387 | Iityhubhu zentsimbi ezifakwe izikrufu nezinesokhethi kunye neetyhubhu zentsimbi ezingenanto ezifanelekileyo zokuwelda okanye zokukrufula kwiintambo zepayipi ze-BS21 |
| Iimpawu zokusebenza | |
| Uxinzelelo Lokusebenza | Umbhobho we-gi kufuneka umelane noxinzelelo olusebenzayo lwemibhobho yeklasi ephakathi yomgangatho we-NBR 5580; |
| Ukumelana nokugqwala | Ngenxa yenkqubo yokufakelwa kwe-galvanization, imibhobho inokumelana okuphezulu nokugqwala, ifanelekile ukusetyenziswa kwiinkqubo zokubonelela ngamanzi okusela; |
| Uqhagamshelo | Iipayipi ze-gi zivumela uqhagamshelo olukhuselekileyo nolungangeni manzi nezinye izinto zenkqubo (iivalvu, izixhobo, njl.njl.) ngokusebenzisa imisonto eqhelekileyo okanye ezinye iindlela ezifanelekileyo. |
