Cov yeeb nkab hlau ovalyog ib lub raj hlau hollow uas muaj ib qho seem oval. Cov kws ua haujlwm feem ntau siv nws thaum ib qhov project xav tau kev tswj lub zog hauv ib qho kev taw qhia, cov npoo du, thiab qhov zoo li huv si. Piv nrog cov kav dej puag ncig lossis plaub fab, cov duab oval hloov pauv kev faib khoom thauj thiab kev coj ua hauv kev pabcuam.
Cov Duab thiab Lub Zog ntawm Ntu
Ib lub yeeb nkab hlau oval muaj ob qhov loj tseem ceeb: ib txoj kab ntev thiab ib txoj kab luv. Vim tias ob txoj kab no txawv, cov yeeb nkab tsis ua haujlwm zoo ib yam hauv txhua qhov kev taw qhia.
Ib lub yeeb nkab tiv taus kev khoov zoo dua li ib lub yeeb nkab puag ncig uas muaj tib qhov hnyav thaum siv lub zog raws nws txoj kab ntev. Qhov no tso cai rau cov kws ua haujlwm muab lub zog tso rau qhov chaw uas nws xav tau tiag tiag. Thaum siv lub zog raws txoj kab luv, qhov kev tiv taus kev khoov qis dua, yog li cov yeeb nkab yuav tsum tau teeb tsa rau hauv qhov kev taw qhia kom raug.
Tsis zoo li cov raj plaub fab lossis cov raj plaub fab, cov raj oval tsis muaj cov ces kaum ntse. Kev ntxhov siab kis tau zoo dua ntawm qhov chaw nkhaus. Qhov no txo qhov kev pheej hmoo ntawm kev tawg thiab txhim kho kev ua haujlwm qaug zog thaum lub sijhawm thauj khoom rov ua dua.
Kev Ua Haujlwm Thauj Khoom hauv Cov Ntawv Thov Txhua Hnub
Nyob rau hauv kev nias lossis kev cuam tshuam me me, cov kav hlau oval deformed hauv txoj kev tswj hwm zoo dua. Cov ces kaum yog qhov tsis muaj zog feem ntau hauv cov kav hlau square, tab sis cov kav hlau oval zam qhov teeb meem no.
Qhov no ua rau lawv haum rau cov ntaiv tes, cov ntaiv tiv thaiv, cov thav duab, thiab cov qauv uas muaj kev co lossis kev sib cuag ntawm tib neeg ntau zaus. Cov duab du kuj ua rau muaj kev nyab xeeb thiab xis nyob thaum siv.
Cov Txheej Txheem Tsim Khoom
Feem ntau cov kav hlau oval yog ua los ntawm cov kav hlau welded. Thiab YUANTAI DERUN muabkev cai oval steel tubing.
Cov hlau ua ntej yog ua ib lub raj puag ncig thiab vuam siv hluav taws xob tiv taus vuam (ERW). Tom qab cov xov vuam raug tiaj thiab kuaj xyuas, lub raj puag ncig raug hla dhau los ntawm cov menyuam uas maj mam hloov nws cov duab mus rau hauv lub voj voog.
Thaum lub sijhawm ua qhov no, yuav tsum tswj ntau yam:
Qhov loj ntawm cov axes ntev thiab luv
Phab ntsa tuab tom qab tsim
Kev ncaj nraim raws qhov ntev ntawm cov yeeb nkab
Qhov chaw ntawm qhov vuam seam
Kev tswj tsis zoo yuav ua rau tuab tsis sib npaug lossis qhov chaw puas. Yuav tsum muaj cov txheej txheem tsim khoom ruaj khov kom cov duab zoo ib yam los ntawm ib pawg mus rau ib pawg.
Kev Xaiv Khoom Siv
Cov hlau ua los ntawm cov pa roj carbon tsawg yog cov khoom siv feem ntau rau cov kav hlau oval.
Raws li peb txhua tus paub cov qib xws li Q235 lossis ASTM A500 yog siv dav vim lawv yooj yim rau kev tsim thiab muaj lub zog ruaj khov. Cov qib muaj zog siab xws li Q355 lossis S355 kuj tseem siv tau, tab sis lawv xav tau kev tswj hwm kev tsim khoom nruj dua.
Rau sab nraum zoov lossis qhov chaw noo noo, feem ntau xaiv cov kav dej oval galvanized kub. Cov txheej zinc tiv thaiv qhov chaw hlau thiab qeeb qeeb xeb. Rau kev siv sab hauv tsev lossis kho kom zoo nkauj, cov kav dej galvanized ua ntej lossis pleev xim feem ntau txaus.
Cov kav dej oval stainless hlau yog siv rau qhov twg qhov kev tiv thaiv corrosion lossis qhov zoo li ntawm qhov chaw yog qhov tseem ceeb, xws li hauv cov haujlwm architectural lossis sab hauv.
Kev Kho Mob Nto thiab Lub Neej Pabcuam
Kev kho qhov chaw cuam tshuam ntau dua li qhov tsos.
Kev galvanizing kub-dip muab kev tiv thaiv xeb mus sij hawm ntev thiab tsim nyog rau cov qauv sab nraum zoov. Cov kav dej galvanized ua ntej muab qhov sib xws zoo dua thiab yooj yim dua rau kev ua, tab sis lawv qhov kev tiv thaiv xeb qis dua.
Feem ntau cov chaw pleev xim lossis hmoov av siv rau hauv cov chaw uas pom tau. Kev ntxuav qhov chaw kom huv yog qhov tseem ceeb kom ntseeg tau tias cov xim pleev zoo thiab siv tau ntev.
Cov Ntawv Thov Ib Txwm Muaj
Cov kav hlau oval feem ntau siv rau hauv:
Cov ntaiv tes thiab cov ntaiv tiv thaiv
Cov ntaub thaiv phab ntsa thiab façade txhawb nqa
Cov thav rooj tog thiab cov ceg rooj
Cov txheej txheem laj kab
Cov khoom siv kho kom zoo nkauj
Hauv cov ntawv thov no, lub duab oval txhim kho ob qho kev tswj hwm lub zog thiab kev nyab xeeb ntawm tus neeg siv.
Kev Sib Piv Nrog Lwm Cov Kav Hlau
Piv nrog cov kav dej puag ncig, cov kav hlau oval muab lub zog khoov siab dua hauv ib qho kev taw qhia yam tsis ntxiv qhov hnyav. Piv nrog cov kav dej plaub fab lossis plaub fab, lawv txo qhov kev ntxhov siab thiab txhim kho kev tiv thaiv kev nkees.
Txawm li cas los xij, cov kav dej oval xav tau kev tsim thiab kev teeb tsa kom meej dua. Kev taw qhia ntawm cov kav dej yuav tsum phim qhov kev taw qhia ntawm kev thauj khoom kom ua tiav qhov kev ua tau zoo tshaj plaws.
Xaus lus
Cov yeeb nkab hlau oval yog ib qho kev daws teeb meem zoo nrog cov txiaj ntsig zoo ntawm kev kho tshuab. Nws cov duab txhim kho kev faib tawm kev ntxhov siab, kev nyab xeeb, thiab qhov zoo nkauj. Thaum tsim nrog kev tswj hwm kev tsim khoom kom raug thiab siv rau hauv qhov kev taw qhia kom raug, cov yeeb nkab hlau oval ua haujlwm tau zoo hauv kev siv cov qauv thiab kho kom zoo nkauj.
