Hydraustatic kuaj:
Cov yeeb nkab steel yuav tsum tau sim ua kom hydraulicically ib qho los ntawm ib qho. Qhov ntsuas qhov siab tshaj plaws yog 20 MPA. Nyob rau hauv qhov kev ntsuas siab, lub sijhawm ua tiav yuav tsum tsis pub tsawg tshaj 10 s, thiab cov yeeb nkab steel yuav tsum tsis txhob xau.
Tom qab tus neeg siv pom zoo, kev xeem hydraulic tuaj yeem hloov los ntawm Eddy kev sim tam sim no lossis sib nqus flux xau.
Kaj ntsuam xyuas:
Tubes nrog ib txoj kab sab nraud loj dua 22 hli yuav raug rau kev ntsuas siab dav. Tsis pom kev txiav txim siab, dawb me me, lossis cov impurities yuav tsum tshwm sim thaum txhua qhov kev sim.
Flaring kuaj:
Raws li cov cai yuav tsum tau ntawm tus neeg yuav khoom thiab tau hais hauv daim ntawv cog lus, cov yeeb nkab steel ≤ 35 xyoos thiab phab ntsa tuab ≤8mm tuaj yeem ua tiav flaring xeem. Kev sim tau ua tiav ntawm chav sov nrog lub taper ntawm 60 °. Tom qab cov nplaim taws, cov nplaim taws ntawm cov taub txheej loj yuav tsum ua kom tau raws li cov kev xav tau ntawm cov lus hauv qab no, thiab cov khoom ntsuas yuav tsum tsis txhob qhia cov kab nrib pleb lossis rips
Kuaj Hardness:
Brinell lossis rockwell hardness chattts yuav tsum tau ua rau cov hnoos qeev los ntawm ob txoj hlab los ntawm ntau
