Cov khoom siv hlau tsis xeb tau siv dav hauv ntau yam lag luam thiab daim ntawv thov vim lawv cov kev ua tau zoo thiab cov khoom zoo heev. Niaj hnub no, peb yuav tham txog cov yeeb nkab tsis xeb thiab cov yeeb nkab ERW, thiab qhov sib txawv ntawm ob yam khoom.
Muaj qee qhov sib txawv ntawm ERW stainless hlau yeeb nkab thiab stainless hlau seamless yeeb nkab. ERW Yeeb Nkab luv rau Electric Resistance Vuam. Nws yog siv los thauj cov kua xws li roj, roj, thiab lwm yam, tsis hais qhov siab, thiab ua lub luag haujlwm tseem ceeb hauv cov kav dej thoob ntiaj teb. Tib lub sijhawm, nws yog ib lub yeeb nkab hlau seamless. Cov yeeb nkab hlau square thiab rectangular tsis muaj pob qij txha thiab hollow profiles yog siv rau kev thauj cov kua vim lawv qhov zoo heev bending thiab torsion zog, nrog rau kev tsim cov khoom siv thiab cov khoom siv kho tshuab. Feem ntau, ERW yeeb nkab thiab seamless yeeb nkab yog siv rau ntau yam lub hom phiaj.
Cov kav hlau tsis muaj qhov tsis sib xws yog ua los ntawm cov hlau puag ncig, thaum cov kav hlau tsis muaj qhov ERW yog ua los ntawm cov kauj kub dov. Txawm hais tias ob yam khoom siv raw sib txawv kiag li, nws yuav tsum nco ntsoov tias qhov zoo ntawm cov khoom kawg - cov kav dej yog nyob ntawm ob yam no - kev tswj xyuas zoo thaum lub sijhawm tsim khoom thiab qhov pib thiab qhov zoo ntawm cov khoom siv raw. Ob lub kav dej yog ua los ntawm cov hlau tsis muaj qhov sib txawv, tab sis feem ntau yog cov kav dej ua los ntawm cov hlau tsis muaj qhov 304.
Lub billet puag ncig raug cua sov thiab thawb rau ntawm tus pas nrig perforated kom txog thaum nws siv cov duab hollow. Tom qab ntawd, lawv qhov ntev thiab tuab raug tswj los ntawm cov txheej txheem extrusion. Hauv cov ntaub ntawv ntawm kev tsim cov kav dej ERW, cov txheej txheem tsim khoom sib txawv kiag li. Lub yob yog khoov rau hauv qhov kev taw qhia axial, thiab cov npoo sib dhos yog welded raws nws tag nrho ntev los ntawm kev tiv thaiv vuam.
Cov kav hlau tsis muaj qhov tsis sib xws tau sib sau ua ke ntawm kab sib dhos thiab muaj nyob rau hauv OD txog li 26 nti. Ntawm qhov tod tes, txawm tias cov tuam txhab hlau siab tshaj plaws nrog ERW thev naus laus zis tsuas yog tuaj yeem ua tiav sab nraud ntawm 24 nti.
Vim tias cov kav dej seamless raug extruded, lawv tsis muaj cov pob qij txha hauv qhov kev taw qhia axial lossis radial. Cov kav dej ERW, ntawm qhov tod tes, yog ua los ntawm kev khoov cov kauj raws lawv lub hauv paus axis kom lawv tau welded raws lawv tag nrho ntev.
Feem ntau, cov kav dej seamless yog siv rau cov ntawv thov siab, thaum cov kav dej ERW yog siv rau kev pabcuam hauv thaj chaw qis thiab nruab nrab.
Tsis tas li ntawd xwb, vim muaj cov yam ntxwv kev nyab xeeb ntawm cov kav dej seamless, lawv siv dav hauv roj thiab roj av, kev ua roj refining thiab lwm yam kev lag luam tshuaj lom neeg, thiab yuav tsum muaj txoj cai tsis pub xau kom ntseeg tau tias muaj kev nyab xeeb ntawm cov neeg thiab cov lag luam. Tib lub sijhawm, cov kav dej ERW zoo ua nyob rau hauv kev tswj hwm zoo nruj kuj tseem siv tau rau cov kev pabcuam zoo sib xws dua li cov kev pabcuam ib txwm muaj xws li kev thauj mus los hauv dej, scaffolding thiab laj kab.
Nws paub tias qhov tiav sab hauv ntawm cov kav dej ERW yeej ib txwm tswj los ntawm cov txheej txheem tswj zoo, yog li lawv yeej ib txwm zoo dua li cov kav dej seamless.
Hauv qhov xwm txheej ntawm ASTM A53, hom S txhais tau tias tsis muaj qhov sib txuas. Hom F - lub cub tawg, tab sis vuam, hom E - tsis kam vuam. Yog li ntawd. Qhov no yog txoj hauv kev yooj yim tshaj plaws los txiav txim siab seb cov yeeb nkab puas yog seamless lossis ERW.
Lub Tswv Yim: ASTM A53 Qib B nrov dua li lwm qib. Cov kav dej no tuaj yeem liab qab yam tsis muaj txheej txheem, lossis lawv tuaj yeem raug galvanized lossis kub-dip galvanized thiab tsim los ntawm kev siv cov txheej txheem tsim khoom welded lossis seamless. Hauv cov roj thiab roj av, cov kav dej A53 yog siv rau cov qauv thiab cov ntawv thov tsis tseem ceeb.
