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. Los yog Kev Ntsuas Hydraulic tuaj yeem hloov tau los ntawm Eddy Tam sim no Kev Ntsuas lossis Kev Ntsuas Flux Magnetic.
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 Qib P91, P92, P122, Thiab P911, Brinell, Vickers, lossis Rockwell Hardness Tests yuav tsum tau ua los ntawm ib qho qauv ntawm txhua qhov ntau.
