Thick-walled steel kav tuaj nyob rau hauv ntau yam steel hom thiab specifications, thiab lawv cov kev ua tau zoo yuav tsum muaj ntau haiv neeg. Tag nrho cov no yuav tsum sib txawv raws li cov neeg siv yuav tsum tau ua lossis kev hloov pauv ntawm kev ua haujlwm. Feem ntau, cov khoom siv yeeb nkab steel raug cais raws li cov duab sib dhos, cov txheej txheem ntau lawm, cov khoom siv yeeb nkab, cov txheej txheem kev sib txuas, cov yam ntxwv txheej thiab siv, thiab lwm yam. Cov yeeb nkab steel tuab tuaj yeem muab faib ua cov kav hlau puag ncig thiab cov kav hlau tshwj xeeb. raws li lawv cov duab cross-sectional. Cov yeeb nkab tshwj xeeb tuab-walled steel kav xa mus rau ntau yam steel kav uas tsis yog lub voj voog hla ntu, nrog rau cov kav dej square, cov kav dej sib npaug, cov kav dej elliptical, cov kav dej tiaj tus, cov kav dej ib nrab, cov kav dej hexagonal, hexagonal puab cov kav dej, thiab sib npaug. hexagons. raj, equilateral daim duab peb sab raj, pentagonal plum blossom raj, octagonal raj, convex raj, biconvex raj. Ob chav concave raj, multi-concave raj, melon zoo li lub raj, tiaj raj, rhombus raj, lub hnub qub raj, parallelogram raj, ribbed raj, nco raj, puab fin tube, twisted raj, B-hom raj, D hom raj, multi- txheej tube, thiab lwm yam.

Thick-walled steel kav txuas ntxiv muab faib ua cov kav dej tas mus li thiab cov kav dej sib txawv-section steel raws li lawv cov duab ntev. Kev sib txawv ntawm ntu (los yog qhov sib txawv ntawm qhov sib txawv) cov kav hlau xa mus rau cov kav hlau uas nws cov kab sib txuas, cov kab nruab nrab sab hauv thiab sab nraud, thiab cov phab ntsa thickness hloov ib ntus lossis tsis tu ncua raws qhov ntev ntawm cov yeeb nkab. Lawv feem ntau suav nrog cov kab tapered sab hauv, sab hauv tapered raj, txheej txheej kauj ruam, sab hauv kauj ruam, ntu ntu raj, corrugated raj, kauv raj, steel raj nrog radiator, thiab phom phom nrog ntau kab.

Txhawm rau txuas ntxiv kev pab cuam lub neej ntawm cov roj thiab cov kav dej, kev kho deg feem ntau yuav tsum tau ua kom yooj yim rau kev sib xyaw ua ke ntawm cov kav dej tuab-walled steel thiab cov txheej tiv thaiv corrosion. Cov kev kho mob feem ntau muaj xws li: ntxuav, tshem tawm cov cuab yeej xeb, pickling, thiab tua blasting.
1. Deg pickling ntawm ncaj seam steel kav: Feem ntau pickling txoj kev muaj xws li tshuaj thiab electrolysis. Txawm li cas los xij, tsuas yog cov tshuaj pickling yog siv los tiv thaiv corrosion ntawm cov kav dej. Chemical pickling tuaj yeem ua tiav qhov kev huv huv siab tshaj plaws thiab roughness ntawm qhov chaw ntawm cov yeeb nkab steel, uas ua rau cov kab txuas txuas ntxiv. Feem ntau yog siv los ua tom qab ua tiav tom qab txhaj tshuaj blasting (xuab zeb).
2. Kev tua blasting thiab xeb tshem tawm: Lub tshuab hluav taws xob muaj zog tsav cov hniav kom tig ntawm kev kub ceev kom cov abrasives xws li steel xuab zeb, steel txhaj tshuaj, cov hlau hlau ntu, thiab cov ntxhia hauv qhov chaw ntawm cov yeeb nkab steel nyob rau hauv qhov kev txiav txim. ntawm lub zog centrifugal. Ntawm qhov tod tes, xeb, oxygen reactants, thiab av, ntawm qhov tod tes, cov yeeb nkab steel ua tiav qhov yuav tsum tau ua kom muaj kev ntxhib los mos nyob rau hauv qhov kev txiav txim ntawm kev ua phem thiab kev sib txhuam ntawm cov abrasive.
3. Kev ntxuav cov yeeb nkab steel tuab: Txhawm rau tshem tawm cov roj, plua plav, cov roj nplua nyeem, thiab cov organic teeb meem uas ua raws li cov kav dej tuab-walled steel, cov kuab tshuaj, thiab cov emulsions feem ntau yog siv los ntxuav qhov chaw. Txawm li cas los xij, cov xeb, cov tshuaj tiv thaiv cov tawv nqaij, thiab vuam slag ntawm cov yeeb nkab steel tsis tuaj yeem raug tshem tawm, thiab lwm yam kev kho mob xav tau.
4. Siv cov cuab yeej tshem tawm xeb los ntawm cov kav hlau ncaj nraim: Txhawm rau tshem tawm cov pa oxygen-reactive daim tawv nqaij, xeb, thiab vuam slag rau ntawm qhov chaw ntawm cov yeeb nkab steel, cov hlau txhuam tuaj yeem siv los ntxuav thiab txhuam qhov chaw. Muaj ob hom kev tshem tawm xeb: phau ntawv thiab lub zog. Kev tshem tawm xeb ntawm phau ntawv cov cuab yeej tuaj yeem ncav cuag qib Sa2, thiab kev tshem tawm xeb ntawm cov cuab yeej hluav taws xob tuaj yeem ncav cuag qib Sa3. Yog tias muaj cov tshuaj tiv thaiv tshwj xeeb uas muaj zog ntawm daim tawv nqaij txuas nrog rau saum npoo ntawm cov yeeb nkab steel, nws yuav tsis tuaj yeem tshem tawm cov xeb txawm tias muaj kev pab los ntawm cov cuab yeej, yog li yuav tsum nrhiav lwm txoj hauv kev.

Ntawm plaub txoj kev kho mob saum npoo rau cov kav dej tuab-walled, txhaj tshuaj blasting yog txoj kev kho zoo tshaj plaws rau cov yeeb nkab xeb tshem tawm. Feem ntau, kev txhaj tshuaj blasting feem ntau yog siv rau kev kho mob sab hauv ntawm cov kav hlau, thiab kev txhaj tshuaj blasting feem ntau yog siv rau sab nrauv kho cov kav hlau.

Txoj kev ua haujlwm tseem ceeb ntawm cov kav dej tuab-walled steel yog dov. Qhov no yog cov txheej txheem siab nyob rau hauv uas cov hlau tsis muaj hlau yog dhau los ntawm qhov sib txawv ntawm ib khub rotating rollers (nyob rau hauv ntau yam duab). Vim yog qhov compression ntawm cov chais, cov khoom hla ntu raug txo thiab qhov ntev ntawm cov yeeb nkab tuab-walled steel yog nce. Txoj kev, qhov no yog ib txoj kev siv ntau lawm rau kev tsim cov hlau, feem ntau yog siv los tsim steel profiles, daim hlau, thiab cov kav dej. Muab faib ua txias dov thiab kub dov. Forging steel: Ib txoj kev ua haujlwm siab uas siv qhov cuam tshuam ntawm lub forging rauj lossis lub siab ntawm cov xovxwm los hloov qhov khoob rau hauv cov duab thiab qhov loj me uas peb xav tau. Feem ntau muab faib ua dawb forging thiab tuag-forging seamless steel kav, steel kav tseem yog ib qho khoom siv tseem ceeb rau ntau yam riam phom. Cov phom phom, cov thoob, thiab lwm yam yog ua los ntawm cov kav hlau. Cov kav hlau hlau tuaj yeem muab faib ua cov kav dej thiab cov kav dej tshwj xeeb raws li qhov sib txawv ntawm qhov sib txawv thiab cov duab. Vim tias cov kab sib npaug sib npaug thiab thaj tsam ntawm lub voj voog loj, cov raj ncig tuaj yeem thauj cov kua dej ntau dua.

Tsis tas li ntawd, lub nplhaib ntu ntawm cov yeeb nkab tuab-walled steel yog qhov sib npaug sib npaug thaum nws dais sab hauv lossis sab nraud radial siab. Yog li ntawd, feem ntau ntawm cov kav hlau uas tuab-walled yog cov kav dej puag ncig. Cov kav hlau muaj qhov hollow thiab tau dav siv los ua cov kav dej rau kev thauj cov kua dej, xws li cov kav dej thauj cov roj, cov nkev, roj, roj, dej, thiab qee yam khoom siv. Piv nrog cov khoom siv steel hlau xws li cov hlau puag ncig, cov kav dej seamless steel yog sib dua hauv qhov hnyav thaum khoov thiab torsional lub zog zoo ib yam. Thick-walled steel kav yog kev lag luam hla ntu hlau thiab tau siv dav hauv kev tsim cov khoom siv thiab cov khoom siv tshuab, xws li cov kav dej tho roj thiab tsheb. Tsav shafts, tsheb kauj vab racks steel scaffolding siv hauv kev tsim kho, thiab lwm yam.
