Kev Tsim Kho Txheej Txheem Txheej txheem cej luam
Cov phiaj xwm hlau steel: 100% Ultrasonic kev xeem yog ua rau cov phiaj tuab siv rau cov yeeb nkab tsim rau cov khoom siv hauv paus yog qhov tsis muaj mob- dawb.
Nyem Milling: Cov npoo ntawm cov phiaj hlau yog milled rau hauv cov duab bevel tshwj xeeb kom ntseeg tau voo qoo.
Pre6 -} bending & JCO / CU tsim: Tom qab ntawm cov xovxwm states tau ua ntej, tom qab ntawd siv cov xovxwm loj, thaum kawg nias rau hauv "O" duab.
Pre6 - vuam: muab ua ntej-}}- shielded vuam los kho cov yeeb nkab.
Sab hauv thiab sab nraud submerged arc vuam: submerged arc vuam yog ua ib zaug nyob sab hauv thiab ib zaug nyob sab nraud ntawm cov yeeb nkab. Lub Arc Tshav Kub Kub hauv Flux tau txais kev pab cuam FLSXE, ua rau muaj kev zoo siab hauv Welds thiab tsim kom zoo.
Txoj kab uas hla: Welded steel yeeb nkab undergoes neeg kho tshuab lossis kab mob hydraulic, yog qhov tseem ceeb. Nws tuaj yeem: tshem tawm cov kev ntxhov siab uas muaj kev ntxhov siab tom qab cov yeeb nkab ua thiab vuam; Txhim kho cov puag ncig thiab kev ncaj ntawm cov yeeb nkab steel; thiab muab "pre {{{{{{{}} pov thawj" xeem ntawv rau weld thiab cov khoom siv hauv paus, ua rau muaj xwm txheej muaj peev xwm.
Kev kho cua sov: x80 hlau kav yog feem ntau xa hauv lub xeev quenched thiab tempered, kom ua tiav qhov kev ua tau zoo siab thiab muaj zog.
Tsis - Kev sim:
100% kev sim ultrasonic ntawm Welds
100% x {- Kev kuaj pom kev sib tw ntawm Welds lossis kev kuaj xyuas TV
Sib nqus part / nkag mus kuaj cov yeeb nkab ntawm cov yeeb nkab xaus (rau kev tshuaj xyuas lub bevel thaj chaw ntawm welds)
Hydrostatic Siab Kuaj: Qhov ntsuas siab yog ua rau txhua qhov kev ntsuas cov yeeb nkab, nrog kev ntsuas siab tsis qis dua tus qauv teev.
Corrosion tiv thaiv txheej: Thaum thov, ib qho anti - corrosion txheej (xws li draw - Txo cov txheej txheem rau sab hauv.
