Ntev:

Qhov ntev li ib txwm muaj ntawm cov kav hlau hlau yog 4 000 hli ~ 12 000 mm. Tom qab kev sib tham ntawm tus neeg xa khoom thiab tus neeg yuav khoom, thiab sau rau daim ntawv cog lus, nws tuaj yeem xa cov kav hlau sib txuas nrog lub sijhawm ntev dua li ntawm I000 mm; Luv luv ntev tus naj npawb ntawm cov kav hlau steel tsawg dua 4,000 hli tab sis tsis pub tsawg tshaj li 3,000 hli yuav tsum tsis pub tshaj 5% ntawm tag nrho cov neeg hlau xa khoom

Tus xa tawm qhov hnyav:
Thaum cov yeeb nkab steel xa tawm raws li lub nroog nominal thiab nominal ntsa tuab lossis nominal ntsa tuab lossis nominal ntsa thickness, cov yeeb nkab steel yog xa raws li qhov hnyav tiag tiag. Nws tseem tuaj yeem xa tawm raws li qhov hnyav.
Thaum cov yeeb nkab steel xa tawm raws li cov nominal sab nraud ntawm lub cheeb thiab tsawg kawg ntawm phab ntsa thickness, cov yeeb nkab steel yog xa raws li qhov hnyav tiag tiag; Cov khoom thiab thov cov tog neeg sib tham. Thiab nws yog qhia hauv daim ntawv cog lus. Cov yeeb nkab steel kuj tseem tuaj yeem xa tawm raws li qhov hnyav hnyav.

Luv Ntshai:
Raws li cov cai ntawm tus neeg yuav khoom, tom qab kev sib tham ntawm tus neeg muag khoom thiab tus neeg yuav khoom, qhov hnyav ntawm kev xa khoom siv tus me nyuam qhov hnyav yuav tsum ua kom tau raws li cov kev cai hauv qab no:
a) Ib Leeg Hlau Yeeb: ± 10%;
b) Txhua pob ntawm cov kav hlau hlau nrog qhov tsawg kawg nkaus ntawm 10 T: ± 7.5%.

Kev xeem yuav tsum tau ua

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.

Nondestructive Test:

Cov kav dej uas yuav tsum tau kuaj xyuas ntau dua yuav tsum yog qhov ntsuas hluav taws xob ultrasonically ib qho los ntawm ib qho. Tom qab cov kev sib tham xav tau kev pom zoo los ntawm tog neeg thiab yog teev nyob rau hauv daim ntawv cog lus, lwm yam kev sim tsis yog kev ua kom tsis yog kev puas tsuaj tuaj yeem ntxiv.

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
