- Cov hlab tau dhau los ua qhov kev sim tam sim no, kuaj hydrostatic, thiab kuaj ultrasonic kom ntseeg tau tias lawv tsis muaj kev cuam tshuam sab hauv thiab txo qhov kev pheej hmoo ntawm kev xau lossis tsis ua haujlwm nyob rau hauv lub zog cyclic.
2. Cov neeg kho tshuab siab zog thiab qaug zog ua haujlwm
- Peb cov hlab yog tsim los ntawm cov khoom siv siab - zoo 25CrMo4 thiab, tom qab kev kho cua sov tsim nyog, muaj lub zog txhua yam thiab kev ua haujlwm zoo heev.
- Cov raj tau raug kuaj xyuas cov tshuaj muaj pes tsawg leeg kom ntseeg tau tias cov khoom sib xyaw ua ke, ua raws li EN 10216-2 cov qauv.
3. Zoo Weldability thiab Machinability
- Peb 25CrMo4 raj muaj nyob rau hauv + SR, + A, lossis + QT cov xwm txheej thiab tuaj yeem hloov kho rau ntau yam kev siv, txawm tias rau cov kav dej boiler, welded Cheebtsam, lossis siab - siab thiab siab - daim ntawv thov kub.
- Cov raj muaj qhov zoo weldability thiab machinability, txhawb nqa ntawm - qhov chaw vuam thiab lub Hoobkas sib dhos, thiab tuaj yeem txiav, laum, tig, lossis milled.
4. Kev kub siab thiab kev kub siab kev ntseeg siab
- Peb cov raj tuav lub zog tensile thiab tawm lub zog ntawm 400-550℃thiab tuaj yeem tiv taus thermal qaug zog los ntawm kev rov ua cua sov thiab cua txias.
- Los ntawm cov txheej txheem txias txias thiab cov txheej txheem kho cua sov, peb cov raj muaj qhov zoo heev -siab tsis kam, ua kom muaj kev nyab xeeb thiab txhim khu kev qha hauv boilers, kub exchangers, thiab lwm yam kev siv siab -siab.
5. Zoo heev Surface Quality thiab Dimensional raug
- Cov hlab ua rau cov duab txias, uas ua rau muaj qhov siab ntawm qhov smoothness. Kev kho deg xws li pickling thiab passivation, thiab sandblasting yog muaj. Cov raj kuj tseem oiled los tiv thaiv kev puas tsuaj thaum khaws cia thiab thauj.
- Cov hlab tau raug soj ntsuam nruj me ntsis kom ntseeg tau tias lawv txoj kab uas hla, phab ntsa thickness, ntev, ncaj, thiab roundness ua raws li EN 10216-2 cov qauv lossis cov neeg siv khoom xav tau.

Cov qhab nia xaiv tau
| Alternative Qib | Yog vim li cas |
| 16 hmo 3 | Tsim tshwj xeeb rau nruab nrab kub thiab siab tej yam kev mob, feem ntau siv nyob rau hauv industrial boilers, tshav kub exchangers, siab hlab ntsha, thiab economizers ua hauj lwm nyob rau hauv nruab nrab kub. |
| T11 / T22 | Cov yam ntxwv ua pov thawj siab - qhov kub thiab txias, kev ua haujlwm siab, thiab kev ua raws li kev cai thoob ntiaj teb, haum rau boilers thiab kub exchangers nyob rau hauv petrochemical nroj tsuag, refineries, thiab fais fab nroj tsuag. |
| 10CrMo9-10 | Muaj kev nkag tau zoo heev thiab ntev - lub sij hawm kev ruaj ntseg, haum rau lub hwj chim cog boilers, chav kav dej, thiab siab - siab headers raug kub kub thiab siab kub siab rau lub sij hawm ntev. |
