Kupita patsogolo kwathu kumadalira zida zapamwamba, luso lapamwamba komanso mphamvu zamaukadaulo zolimbitsa nthawi zonse za Best Quality China High Pressure Boiler Seamless AlloyChitsuloChitoliro cha Stba12 Stba13 Stba20 Stba22 Boiler Steel Pipe, Timatha kusintha mayankho malinga ndi zosowa zanu ndipo titha kukunyamulani mosavuta mukagula.
Kupita patsogolo kwathu kumadalira zida zapamwamba, luso lapamwamba komanso mphamvu zamaukadaulo zomwe zimalimbikitsidwa nthawi zonseChina Steel Pipe, Chitsulo, Timakhazikitsa dongosolo lowongolera khalidwe labwino. Tsopano tabwereranso ndikusinthanitsa mfundo, ndipo mutha kusinthana mkati mwa masiku 7 mutalandira ma wigs ngati ali pamalo atsopano ndipo tikukonza zaulere kuti tipeze mayankho athu. Chonde khalani omasuka kulumikizana nafe kuti mumve zambiri ndipo tidzakupatsani mndandanda wamitengo yopikisana ndiye.
Mwachidule
Kugwiritsa ntchito
Amagwiritsidwa ntchito kwambiri popanga zitsulo zamtengo wapatali za carbon structural steel, low pressure medium boiler boiler pipe, super heat heatless carbon steel pipe
Main Grade
Kalasi ya apamwamba mpweya structural zitsulo: 10 #, 20 #

Chofunikira Choyesa
Mayeso osalala
Machubu achitsulo okhala ndi m'mimba mwake wamkulu kuposa 22 mm mpaka 400 mm, ndi makulidwe a khoma kuposa 10 mm ayenera kuyezetsa kupendeketsa. Pambuyo sampuli ndi flatten
Mayeso opindika
Machubu achitsulo okhala ndi m'mimba mwake osapitirira 22 mm ayenera kuyesedwa. Mbali yopindika ndi 90o. Radiyo yopindika ndi nthawi ya 6 yakunja kwa chubu chachitsulo. Pambuyo popinda chitsanzo, palibe ming'alu kapena ming'alu yomwe imaloledwa kuwonekera pa chitsanzo.
Kuyeza kwa macroscopic
Kwa machubu achitsulo opangidwa mwachindunji ndi ma billets kapena zitsulo zachitsulo mosalekeza, woperekayo akuyenera kutsimikizira kuti palibe mawanga oyera, zonyansa, thovu lamlengalenga, zigamba zachigaza kapena kusanjika pamtundu wa asidi wowotcha macroscopic minofu ya billet kapena chubu chachitsulo.
Kuwunika kosawononga
Malinga ndi wovuta pempho la chipani, amene ndiye kukambirana pakati pa kupereka ndi wovuta maphwando ndi anasonyeza mu mgwirizano, akupanga chilema kudziwika akhoza payekha anachita kwa zitsulo machubu. Chilema chautali wa chubu lachitsanzo chiyenera kukwaniritsa zofunikira za kalasi yovomerezeka pambuyo poyang'anira C8 yotchulidwa mu GB/T 5777-1996.
