Muunad bilaash ah oo loogu talagalay Shiinaha ASTM A53/BS1387 Dhuumaha birta galvanized ee kulul iyo isku xidhan
Dulmar
Xubin kasta oo ka mid ah shaqaalaheenna dakhligoodu waa weyn wuxuu qiimeeyaa shuruudaha macaamiisha iyo xiriirka ururka ASTM A53/BS1387 Hot Dipped Galvanized Steel Pipe. Anaga oo lacagtaada si badbaado leh ganacsigaaga u badbaadsan. Waxaan rajeyneynaa inaan noqon karno alaab-qeybiye lagu aamini karo Shiinaha . Waxaan rajeyneynaa iskaashigaaga .In ka badan 9 sano oo waayo-aragnimo ah iyo koox xirfad leh, waxaan u dhoofinay alaabadayada dalal badan iyo gobollo badan oo adduunka ah. Waxaan soo dhawaynaynaa macaamiisha, ururada ganacsiga iyo asxaabta ka kala yimid dhammaan qaybaha adduunka si ay nala soo xiriiraan oo ay u raadiyaan iskaashi faa'iidooyinka labada dhinac.
Galvanizing-ku-kululku wuxuu leeyahay faa'iidooyinka dahaarka labbiska ah, dhejinta xooggan iyo nolosha adeegga dheer. Falcelinta jirka iyo kiimikaad ee adag ayaa ka dhex dhaca matrixka tuubada birta iyo xalka dhalaalka ah si ay u sameeyaan lakab daaha zinc-birta u adkaysta oo leh qaab dhismeed is haysta. Lakabka daawaha waxaa lagu dhex daray lakabka zinc saafiga ah iyo matrixka tuubada birta. Sidaa darteed, iska caabinteeda daxalka waa mid xooggan.
Waxaa loo baahan yahay in la ogaado in 1960-yadii iyo 1970-meeyadii, dalalka horumaray ee dunidu waxay bilaabeen inay horumariyaan noocyada cusub ee tuubooyinka oo si tartiib tartiib ah loo mamnuucay tuubooyinka galvanized. Afar wasaaradood iyo guddiyo ay ka mid tahay wasaaradda dhismaha ee Shiinaha ayaa iyaguna soo saaray dukumeenti cadeynaya in tuubooyinka galvanized la mamnuucay laga bilaabo 2000 wixii ka dambeeya. Tuubooyinka galvanized ayaa naadir loo isticmaalaa tuubooyinka biyaha qabow ee bulshooyinka dhowaan la dhisay, iyo tuubooyinka galvanized ayaa loo isticmaalaa tuubooyinka biyaha kulul ee beelaha qaarkood.
Codsiga
Waxaa inta badan loo isticmaalaa qaybaha xoogga iyo cadaadiska, iyo ujeedada guud uumiga, biyaha, gaaska iyo tuubooyinka hawada.
