Kev Xeem Xeem
Hydraustatic Test:
Cov yeeb nkab steel yuav tsum tau sim Hydraulic ib leeg. Qhov ntsuas siab tshaj plaws yog 20 MPa. Nyob rau hauv qhov kev sim siab, lub sij hawm ruaj khov yuav tsum tsis pub tsawg tshaj 10 S, thiab cov yeeb nkab hlau yuav tsum tsis txhob tawm.
Tom qab tus neeg siv pom zoo, Kev Ntsuas Hydraulic tuaj yeem hloov tau los ntawm Eddy Tam sim no Kev Ntsuas lossis Kev Ntsuas Flux Flux.
Nondestructive Test:
Cov kav dej uas xav tau kev tshuaj xyuas ntau dua yuav tsum tau kuaj xyuas Ultrasonically ib qho los ntawm ib qho. Tom qab Kev Sib Tham Yuav Tsum Tau Txais Kev Pom Zoo Los ntawm Pawg Neeg thiab tau teev tseg hauv daim ntawv cog lus, lwm yam kev sim tsis muaj kev puas tsuaj tuaj yeem raug ntxiv.
Flattening Test:
Tubes nrog ib txoj kab uas hla sab nraud loj dua 22 hli yuav tsum raug rau qhov kev ntsuam xyuas flattening. Tsis pom kev delamination, pob dawb, lossis impurities yuav tsum tshwm sim thaum tag nrho kev sim.
Hardness Test:
Rau cov yeeb nkab ntawm Qib P91, P92, P122, thiab P911, Brinell, Vickers, lossis Rockwell hardness tests yuav tsum tau ua ntawm ib qho qauv ntawm txhua qhov ntau.
Khoov Test:
Rau cov yeeb nkab uas nws txoj kab uas hla tshaj NPS 25 thiab nws txoj kab uas hla mus rau phab ntsa thickness piv yog 7.0 los yog tsawg dua yuav tsum raug rau qhov khoov xeem es tsis txhob flattening xeem. Lwm cov yeeb nkab uas nws txoj kab uas hla sib npaug lossis tshaj NPS 10 tuaj yeem muab qhov kev sim khoov rau qhov chaw ntawm qhov kev sib tw flattening raws li kev pom zoo ntawm tus neeg yuav khoom
