Nyob rau hauv xyoo tas los no, stainless hlau zawv zawg qhov rooj kho vajtse thiab barn qhov rooj kho vajtse uas tau nrov nyob rau hauv kev ua lag luam feem ntau siv stainless hlau rails nrog seam kav thiab seamless kav. Tom ntej no, peb yuav qhia qhov sib txawv ntawm cov kav dej seamless thiab seamless kav:
1. Qhov luaj li cas ntawm cov hlau stainless cov lus qhia rails: feem ntau, qhov loj ntawm cov nplej hlau muaj feem xyuam rau qhov kub thiab txias ntawm kev kho cua sov thiab lub sij hawm nws yuav siv sij hawm los txuas rau qhov kub thiab txias. Yog li ntawd, cov qoob loo loj ntawm ob lub welded kav thiab seamless steel kav rau txim los ntawm kev kho annealing yog tib yam. Yog hais tias muaj ib qho kev nplua me me rau cov kav dej welded, cov nplej loj ntawm cov hlua khi yuav me dua li cov nplej loj ntawm cov hlau welded, txwv tsis pub cov nplej loj yuav zoo ib yam.
2. Concentricity ntawm stainless hlau qhia rails: Cov txheej txheem ntawm seamless steel kav yog xuas nrig ntaus ib lub qhov nyob rau hauv stainless hlau billet ntawm ib tug kub ntawm 22 00f, thiab nyob rau hauv no kub kub, lub sab hnub tuaj-sab hnub poob hlau yuav ua mos thiab kauv zoo li lub qhov los ntawm stamping thiab kos duab. Phab ntsa thickness ntawm xws li pipelines yog uneven thiab nyiam heev. Yog li ntawd, astm tso cai rau phab ntsa thickness sib txawv ntawm seamless steel kav yuav ntau dua li ntawm seamless kav. Cov kav dej seamed yog tsim los ntawm cov ntaub ntawv txias-kuav los tiag (txhua yob muaj qhov dav ntawm 4-5 ko taw). Cov phaj txias txias no feem ntau muaj qhov sib txawv ntawm phab ntsa tuab ntawm 0.001MM. Cov phaj hlau raug txiav rau hauv qhov dav ntawm π B (qhov B yog qhov dav ntawm cov kav dej). Lub thickness ntawm lub slit tube nyob rau hauv cov kev pab cuam pej xeem yog heev me me, thiab cov phab ntsa thickness ntawm tag nrho cov ncig yog heev uniform.
3. Nqi: Tus nqi ntawm seamless steel kav yog feem ntau tsuas yog ib nrab ntawm cov seamless steel kav.
