| Njira zopangira mapaipi/machubu zitsulo zosapanga dzimbiri: |
| Zosankha za Surface Finish: |
Timapereka mitundu iwiri ya mayendedwe a brushing kuti tikwaniritse zosowa zosiyanasiyana zokongoletsa ndi magwiridwe antchito:
Mzere Watsitsi Wowongoka (Kutsuka tsitsi Longitudinal):
Njere imayendera kutalika kwa chubu, ndikupanga mawonekedwe osalala komanso osalekeza. Zoyenera kukongoletsa ma elevator, ma njanji omanga, machubu amipando, ndi ntchito zina zapamwamba.
Cross Tsitsi (Kutsuka Burashi):
Njerezo zimazungulira mozungulira chubu, ndikupereka mawonekedwe apadera a zoyika zomangira, zigawo zamapangidwe, ndi mapangidwe okongoletsa.

Ku SAKY STEEL timayesa kuuma mwamphamvu pa mapaipi achitsulo chosapanga dzimbiri kuti tiwonetsetse kuti pamakhala malo osalala komanso osasinthika omwe amakwaniritsa miyezo yapadziko lonse lapansi. Kuvuta kwa chitoliro ndichinthu chofunikira kwambiri chomwe chimakhudza kukana kwa dzimbiri kwakuyenda bwino komanso magwiridwe antchito onse pamapulogalamu ovuta.
Timagwiritsa ntchito zida zolondola kuyeza makulidwe apamwamba kuwonetsetsa kuti mapaipi onse amakwaniritsa zofunikira za kasitomala kuti azitha kusalala komanso kumaliza. Mapaipi athu ndi abwino kwa mafakitale opanga zakudya zam'madzi komanso zamapangidwe komwe kumayenera kukhala koyenera.

Kutha kwapaipi yazitsulo zosapanga dzimbiri ndikofunikira kwambiri pakuchita bwino komanso mawonekedwe. Ku SAKY STEEL timayendetsa mosamalitsa kukongola kwa pamwamba kudzera mumayendedwe apamwamba kwambiri. Chithunzichi chikuwonetsa kufananitsa bwino pakati pa mapaipi oyipa okhala ndi zolakwika zowoneka bwino komanso mapaipi athu abwino okhala ndi kumaliza kosalala komanso kofanana.
Mipope yathu yachitsulo chosapanga dzimbiri ilibe ming'alu ya ming'alu ndi zizindikiro zowotcherera zomwe zimatsimikizira kulimba kwa dzimbiri komanso kudalirika. Mapaipiwa amagwiritsidwa ntchito kwambiri m'madzi am'madzi komanso m'mapangidwe omwe amafunikira kukhulupirika kwapamtunda.
| 304 Stainless Steel Welded Pipe PT Test |
SAKY STEEL imapanga kuyesa kolowera kwa PT pamapaipi achitsulo chosapanga dzimbiri ndi zigawo zina monga gawo lathu lokhazikika lowongolera. PT ndi njira yoyesera yosawononga yomwe imagwiritsidwa ntchito kuti izindikire zolakwika zapamtunda monga ming'alu ya porosity ndi inclusions zomwe sizikuwoneka ndi maso.
Oyang'anira athu ophunzitsidwa amagwiritsa ntchito zida zapamwamba zolowera komanso zopanga kuti zitsimikizire zolondola komanso zodalirika. Njira zonse za PT zimatsata miyezo yapadziko lonse lapansi komanso zomwe kasitomala amatsimikizira chitetezo ndi magwiridwe antchito.

| Weld Seam Kuyendera kwa 304 Stainless Steel Welded Pipe |
Chitsulo chosapanga dzimbiri chitoliro weld msoko kuyang'ana amaonetsetsa kuti olowa onse welded kukwaniritsa chofunika ndi mfundo chitetezo. Njira yowunikirayi imayang'ana pakuzindikira zolakwika zamkati ndi zamkati monga ming'alu, porosity, slag inclusions, kusowa kwa kuphatikizika, ndi kulowa kosakwanira. Njira zodziwika bwino zimaphatikizira kuyang'anira zowona, kuyezetsa kolowera kwa utoto, kuyesa kwa ultrasonic, ndi kuyesa kwa radiographic. Njira iliyonse imasankhidwa potengera zinthu za chitoliro, makulidwe a khoma, ndi zikhalidwe zautumiki. Kuyang'anira konse kumachitika molingana ndi miyezo yapadziko lonse lapansi monga ASME, ASTM, ndi ISO kuti zitsimikizire kukhulupirika ndi magwiridwe antchito a mapaipi owotcherera.

| Njira Yapaintaneti Kulumikiza Chitoliro Chopanda Zitsulo Chosapanga dzimbiri |
In-line solution annealing of Stainless steel pipe ndi njira yosalekeza yochizira kutentha yomwe imagwiritsidwa ntchito popanga kuti ikwaniritse mawonekedwe a austenitic microstructure ndikukulitsa kukana kwa dzimbiri. Chitolirocho chimatenthedwa ndi kutentha komwe kwatchulidwako, komwe kumakhala pakati pa 1000 ° C ndi 1150 ° C, kenako kuziziritsidwa mwachangu, nthawi zambiri pogwiritsa ntchito kuzimitsa madzi kapena kuziziritsa mpweya mokakamiza. Izi zimasungunula carbide precipitates ndikuletsa dzimbiri intergranular, kuonetsetsa kuti mawotchi katundu ndi pamwamba khalidwe kukumana mfundo mayiko. In-line solution annealing imathandizira kupanga bwino ndikusunga magwiridwe antchito azinthu.
