Cov khoom tsim los ntawm cov kav dej seamless txawv, thiab cov ntsiab lus sib txawv. Feem ntau hais lus, peb cov kav dej seamless steel tsis yooj yim rau xeb. Tab sis nws tsis tau txhais hais tias seamless steel yeeb nkab tsis yooj yim rau xeb, peb feem ntau tsis quav ntsej nws, vim hais tias yog cov seamless steel yeeb nkab feem ntau tsis tswj, nws cov kev pab cuam lub neej yuav luv luv, thiab nws kuj yuav ua rau inconvenience. rau peb seamless yeeb nkab Hoobkas thiab cov neeg muas zaub tsim nyog poob. Txij li txhua tus neeg yuav cov kav hlau tsis sib haum, lawv yuav tsum cia siab tias lub neej kev pabcuam tuaj yeem ntev dua, yog li txhua tus neeg yuav tsum tau saib xyuas cov kav dej seamless steel.

Txhawm rau ua kom lub neej ua haujlwm ntawm cov yeeb nkab seamless hauv cov txheej txheem, cov yeeb nkab seamless steel yuav tsum tau ua ntej kom tshem tawm cov nplais saum npoo, thiab tom qab ntawd lubricated, kom cov yeeb nkab steel yog pickled thiab passivated los tsim cov yeeb yaj kiab tiv thaiv ntawm qhov chaw. . Tom qab ntawd, tom qab pickling, electrolysis tuaj yeem siv los ntxiv cov seamless steel yeeb nkab kom tiv thaiv nws ntxiv.

Cov kev cai zoo rau seamless steel yeeb nkab blanks yog ze ze rau cov txheej txheem tho. Muaj cov kev ntxhov siab tsis zoo thiab qhov tsis sib xws loj heev thaum tho thiab dov cov hlab capillary ntawm ob-yob piercer. Yog li ntawd, cov teeb meem hauv zos uas muaj nyob rau ntawm qhov khoob yog nthuav dav los ntawm perforation, ua rau muaj qhov tsis xws luag ntawm sab hauv thiab sab nrauv ntawm capillary. Tshwj xeeb tshaj yog nyob rau hauv qee qhov chaw tsis muaj zog hauv cov hlau qub - qhov twg tsis yog xim hlau suav nrog kev ua tsis zoo, nws yog qhov yooj yim los ua kev puas tsuaj rau cov hlau los ntawm kev ua txhaum rau cov hlau. Yog li ntawd, xaiv txoj kev tsim nyog perforation thiab hloov cov kev ntxhov siab tsis zoo tuaj yeem tiv thaiv qhov tsis xws luag thiab txo cov kev xav tau ntawm seamless steel yeeb nkab blanks. Qhov tseem ceeb ntawm seamless steel yeeb nkab yog muab cov yeeb nkab ncaj qha rau hauv cov yeeb nkab fittings los ntawm nias. Qhov tseem ceeb ntawm ob qhov kawg yog cov protruding U-shaped grooves. Tsis tas li ntawd, nws tuaj yeem muab tso rau hauv lub qhov (socket) rau kev sib txuas ceev. Lub tshuab tho peb-yob, phau ntawv qhia phaj tho tshuab, thiab cov tshuab tho pwm uas tau tshwm sim nyob rau hauv xyoo tas los no yog peb txoj kev sib tw zoo dua. Push piercing (PPM) yog ib txoj hauv kev zoo rau kev tho ncaj qha rau lub pob zeb. Siv cov kev tho no, tshwj xeeb tshaj yog cov kab mob-hom tho tshuab, tsis tsuas yog tuaj yeem tho thiab dov nruam casting slabs, tab sis kuj high-alloy steel yuav pierced thiab dov.

Raws li rau ob-cov menyuam piercer nrog daim ntawv qhia, kev txhim kho cov txheej txheem tho tuaj yeem siv los tiv thaiv qhov tsis xws luag, yog li txo cov kev xav tau zoo rau seamless steel yeeb nkab blanks.
