Zam tximCob rau lub tsev kev lag luam, nws siv yog ntau dav, los ntawm lub tswvyim ntawm:Zam tximPuas yog cov hlau yog siv nias, los ntawm kev deformation yas kom ua cov duab uas xav tau lossis lub zog tseem ceeb ntawm cov khoom.
Kev zamyog kev siv cov khoom forging ua rau kev zam txim ntawm bar Tshuag, feem ntau tsis tuaj yeemkev zamIb qho kev ua yeeb yam ntxiv, xav tau cov teeb meem loj, xws li siv cov chaw nyob hauv kev txiav txim siab, yog li nws tau siv lub valve thiab muaj zog corrosion valve , Forging lub cev kuj yog siv dav.
Piv nrog castings, lub cev ntawm forged li qub muaj ntau cov qauv qauv, zoo dua qub, zoo dua lub zog kev ncaj ncees, thiab tsawg dua kev ua yuam kev. Kev tsim kho kev tsim kho (pipeline) muaj kev ua haujlwm siab dua li castings nyob rau hauv cov nqe lus ntawm tag nrho lub zog thiab kev ntxhov siab.
Lub zog siab - kubkev zamTxhawb nqa Crystallization thiab cov khoom siv qoob loo, cia cov khoom siv kom ua tiav qhov siab tshaj plaws thiab xwm yeem nrog tsawg tsawg los ntawm ib feem. Hais ntws tawm meej raws lub cev profile. Cov hluav taws xob txuas ntxiv no pab kom txo qhov tshwm sim ntawm kev qaug zog lossis ua txhaum.

Cov Txheej Txheem Kev Ncaj Ncees - Forging tshem tawm cov kev tsis taus sab hauv thiab tsim kom muaj kev sib koom ua ke thiab cov hlau sib dhos, ua kom muaj kev ua tau zoo heev.Zam tximMuab lub neej pabcuam ntev thiab teeb meem-pub dawb qhov kev ntxhov siab thiab hauv-crystal corrosion yog qhov teeb meem loj.
Kev ntseeg tau - Cov qauv kev ntseeg siab lees paub tshem tawm kev tshem tawm sab hauv thiab tsim kom muaj cov qauv sib dhos thiab ua kom muaj kev ua tau zoo. Kev lees paub muab lub neej pabcuam ntev thiab teeb meem-pub dawb qhov kev ntxhov siab thiab hauv-crystal corrosion yog qhov teeb meem loj.
Kev lees paub zoo - los ntawm kev siv kev zam txim, nrog lawv sib xws, qhov kev xav tau rau X-Rays rau chav kawm 1 nrum feem yog tshem tawm. Tebchaws Asmeskas Navy tuav tus cwj pwm tib yam thaum siv kev zam txim raws li cov khoom sib xyaw ntawm Nucraft cov khoom noj thiab cov dav hlau. Txhua tus raws li cov cai ua rau kev lom zem yog ultrasonic kev tshuaj xyuas (UT), nqus cov pa kev sib nqus (PT). Seem foob tsis pom zoo los ntawm UT, MT, lossis PT txoj kev yog tsawg heev. Cov Cheebtsam tau yuav nrog cov khoom siv lub sijhawm xa khoom, yog li valve tus me nyuam muaj kev ntseeg tau ntau dua.
Kev teeb tsa kev teeb tsa ntawm valiguration ntawm valve lub cev - creep qaug zog dag yog ntau tshaj 3 lub sij hawm siab tshaj li ntawm cov kab mob hauv qab kub hloov.
Lub tuam txhab lub ntsiabflange, kev zam, Forging ua, cov lus nug lossis xav tau txais tos kom nug thiab sib tham.
