Kev Xeem Xeem
Qhia qee qhov kev xeem ib txwm siv rau kev siv, rau cov qauv sib txawv, thov saib tus qauv nthuav dav.
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.
Flaring Test:
Raws li qhov yuav tsum tau muaj ntawm tus neeg yuav khoom thiab tau teev nyob rau hauv daim ntawv cog lus, cov yeeb nkab steel nrog txheej txheej ≤76mm thiab phab ntsa Thickness ≤8mm tuaj yeem ua tiav Flaring Test. Qhov kev sim tau ua nyob rau hauv chav kub nrog ib tug taper ntawm 60 °. Tom qab Flaring, Qhov Flaring Rate ntawm Sab Nrauv Sab Nraud Yuav Tsum Tau Ua Raws Li Cov Lus Qhia hauv qab no, thiab cov khoom siv kuaj yuav tsum tsis txhob muaj qhov tawg lossis tawg.
