German kev lag luam cog khoom hnyav khoom txhawb nqa qhov project
Nyob rau hauv ib qho kev kho dua tshiab ntawm lub Hoobkas muaj kev lag luam hauv lub teb chaws Yelemees, S355J2 HEM120 H-section steel tau siv los ua cov txheej txheem txhawb nqa rau lub hauv paus ntawm cov tshuab loj, suav nrog cov cuab yeej siv tshuab thiab crushers.
Qhov tuab flange tsim ntawm S355J2 HEM120 tso cai rau kev sib txuas ncaj qha ntawm cov ntsia hlau thauj tog rau nkoj yam tsis muaj kev txhawb nqa ntxiv, ua kom lub sijhawm ntev - ruaj khov thiab kev nyab xeeb ntawm cov khoom siv.
Tag nrho ntawm 28 S355J2 HEM120 kab teeb, hnyav kwv yees li 560 tons, tau siv hauv qhov project. Thaum lub sij hawm tsim kho, cov kab teeb pom kev zoo thiab siab - lub zog vuam tau ua kom nrawm nrawm ntawm lub hauv paus kev txhawb nqa, ua kom muaj kev ruaj khov ntawm cov tshuab hnyav thaum txhim kho cov load-cov kabmob muaj peev xwm thiab kev tsim kho ntawm lub Hoobkas qauv.
S355J2 HEM120 H-Beam Fabrication thiab Procurement Guidelines
Vuam txheej txheem: Qhov tuab flange ntawm HEM120 (21 mm) yog suav tias yog tuab - phaj vuam. Nws raug nquahu kom siv qis -hydrogen electrodes thiab nruj me ntsis tswj qhov kub ntawm qhov sib cuam tshuam tsawg dua lossis sib npaug li 250℃. Tom qab vuam, tom qab-weld hydrogen tshem tawm yuav tsum tau ua kom ntseeg tau tias vuam zoo thiab kev ua haujlwm zoo.
Kev soj ntsuam zoo thiab cov ntaub ntawv pov thawj: Peb tuaj yeem muab S355J2 Material Test Certificate (MTC), uas suav nrog kev txheeb xyuas cov khoom tseem ceeb xws li kev cuam tshuam lub zog.
Rau tuab -phab ntsa H- kab teeb, nws raug nquahu kom ua ultrasonic kuaj (UT) kom ntseeg tau tias tsis muaj qhov tsis xws luag, txhim kho kev tsim kho kev nyab xeeb thiab kev ntseeg tau ntawm cov qauv.
