Lub raj square yog dab tsi?
Lub raj plaub fab— hu ua raws li txoj caiSeem Hollow Square (SHS)— yog ib daim hlau profile uas muaj ib daim duab plaub fab. Nws pom txhua qhov chaw hauv kev tsim kho, kev tsim tshuab, thiab kev ua haujlwm hlau. Feem ntau cov raj square yog ua los ntawm cov hlau carbon, hlau stainless, lossis txhuas alloy, thiab lawv muaj ntau qhov ntau thiab tsawg thiab phab ntsa tuab kom haum rau ntau yam kev xav tau engineering.
Yuav Ua Li Cas Cov Tubes Plaub Hau Thiaj Li Raug Faib Tawm
Los ntawm txoj kev tsim khoom
Seamless square raj: tsis muaj weld seam, yog li nws tswj tau qhov siab zoo dua thiab feem ntau muab lub zog siab dua.
Welded square raj: tsim thiab vuam los ntawm cov kab tiaj tiaj; pheej yig dua, txawm hais tias cov kab vuam yog ib qho tseem ceeb uas yuav tsum xav txog hauv cov ntawv thov kev ntxhov siab siab.
Los ntawm cov khoom siv
Cov hlau carbon, cov hlau tsis xeb, thiab cov hlau sib xyaw yog cov kev xaiv feem ntau.
Los ntawm kev siv kawg
Cov qib kev tsim kho, kev kho kom zoo nkauj, thiab kev kos duab txhua tus muaj lub hom phiaj sib txawv.
Los ntawm qhov chaw tiav
Cov raj xa dej galvanized, pleev xim, lossis dub liab qab - qhov kev xaiv feem ntau nyob ntawm qhov chaw ib puag ncig thiab peev nyiaj.
Cov Yam Ntxwv Tseem Ceeb
Muaj zog rau lawv qhov hnyav.Qhov seem hollow ua rau kev siv khoom tsawg thaum tseem khaws cia qhov tsis kam rau khoov thiab torsion.
Yooj yim rau kev ua haujlwm nrog.Kev txiav, vuam, thiab khawb yog txhua yam yooj yim, yog li kev teeb tsa rau ntawm qhov chaw feem ntau ua haujlwm sai.
Tiv taus xeb thaum xav tau.Cov qauv galvanized lossis stainless hlau tuav tau zoo nyob rau hauv cov chaw ntub dej lossis cov tshuaj lom neeg hnyav.
Zoo nkauj huv si.Qhov ncaj, cov qauv sib xws ua rau lawv haum rau cov ntawv thov pom xws li railings thiab facade framing.
Qhov Loj Feem Ntau
| Cov Qauv | Qhov ntau yam |
| Qhov ntev ntawm sab | 10 × 10 hli txog 500 × 500 hli (muaj ntau qhov loj me) |
| Phab ntsa tuab | 0.5 hli - 20 hli; cov ntsuas feem ntau suav nrog 1.0, 1.5, 2.0, thiab 3.0 hli |

4.0 – 6.0 hli:cov khoom hnyav — cov thav duab uas dais tau lub nra hnyav, cov ncej Hoobkas, cov hauv paus tshuab hnyav.
Yuav Ua Li Cas Cov Raj Plaub Hau
Txoj kev tsim khoom txiav txim siab seb lub raj puas yog seamless lossis welded.
Cov raj xa dej tsis muaj qhov sib txuasPib ua cov kav dej tsis muaj qhov sib txuas uas tsim los ntawm kev tho thiab dov kab, tom qab ntawd rov ua dua tshiab rau hauv cov duab plaub fab los ntawm kev rho tawm. Vim tias tsis muaj kev vuam, lawv muab lub zog sib xws thiab qhov tseeb ntawm qhov ntev, ua rau lawv yog qhov kev xaiv zoo rau cov lag luam xav tau xws li roj thiab roj av thiab kev ua cov khoom siv roj av.
Cov raj xa dej squareyog tsim los ntawm kev dov cov hlau tiaj tiaj ua cov duab thiab vuam cov xov kom kaw. Lawv raug nqi kwv yees li 30–50% pheej yig dua li cov khoom sib npaug seamless thiab tseem ceeb hauv kev tsim kho dav dav thiab cov ntawv thov tshuab uas tsis tas yuav tiv taus siab heev.

Vim li cas thiaj xaiv Square Tubes?
Kev ua haujlwm zoo ntawm cov khoom siv.Cov hlau tsawg dua li cov hlau khov kho uas muaj qhov loj sib npaug, uas ua rau tus nqi qis dua thiab yooj yim dua rau kev tuav.
Kev tsim kho sai dua.Sib dua rau kev thauj mus los thiab yooj yim dua rau kev teeb tsa, pab kom cov sijhawm ua haujlwm raws sijhawm.
Kev ua tau ntau yam.Tib daim profile no tuaj yeem nqa cov khoom hnyav lossis ua haujlwm zoo nkauj xwb.
Kev ruaj khov.Cov hlau yog cov khoom siv rov ua dua tshiab, ua raws li cov kev cai niaj hnub ntawm kev tsim kho ntsuab.
Qhov twg siv cov raj plaub fab
Kev Tsim Kho
Cov raj plaub fabyog cov khoom tseem ceeb hauv cov thav hlau, cov choj, thiab cov ntaiv txoj kev loj. Lawv qhov kev sib xyaw ua ke ntawm lub zog, qhov hnyav sib dua, thiab qhov zoo nkauj tau ua rau lawv yog cov khoom siv tseem ceeb hauv kev tsim kho niaj hnub.
Cov qauv hlauCov chaw loj xws li cov chaw tsim khoom thiab cov chaw ua si nawv vam khom SHS ntau heev. Lub National Speed Skating Oval ("Ice Ribbon") uas tau tsim rau Beijing Winter Olympics, piv txwv li, siv cov qauv grid welded uas muaj zog heev.
Cov ntawv thov kho kom zoo nkauj: cov kav hlau stainless hlau feem ntau raug xaiv rau cov ntaiv tes thiab cov ntaub thaiv phab ntsa vim lawv txoj kev tiv thaiv corrosion thiab ua tiav huv si.
Kev Tsim Khoom Siv Tshuab
Cov raj plaub fab feem ntau siv rau cov thav khoom siv, cov menyuam thauj khoom, thiab cov ceg txhawb nqa. Piv txwv li, ib txoj kab ntau lawm tsis siv neeg feem ntau yuav siv cov raj plaub fab 40 × 40 × 2 hli rau cov kev txhawb nqa siv txoj siv thauj khoom. Lawv cov khoom siv kho tshuab thiab yooj yim ntawm kev tsim khoom ua rau lawv yog qhov kev xaiv txhim khu kev qha thoob plaws hauv kev lag luam.
Tsheb thiab Kev Thauj Mus Los
Hauv kev tsim tsheb, cov raj plaub fab tshwm sim hauv cov khoom siv txhawb nqa chassis, cov pa tawm, thiab cov kav roj. SHS muaj zog siab kuj tseem muaj nyob rau hauv cov thav tsheb ciav hlau ceev ceev. Qee cov qauv tsheb fais fab tshiab siv cov raj plaub fab txhuas alloy rau cov brackets roj teeb, ua tiav qhov hnyav txo qis li ntawm 30%.
Lwm Cov Chaw
Cov tsev cog khoom ua liaj ua teb: cov kav dej galvanized square tiv taus xeb thiab yog cov khoom siv pob txha txheem rau cov qauv tsev cog khoom.
Rooj tog: ntau lub txee lag luam thiab cov rooj tog siv cov raj nyias nyias kom sib npaug qhov zoo li nrog lub peev xwm thauj khoom.
Daim Ntawv Teev Xyuas Kev Tshuaj Xyuas Zoo
Kev kam rau siab ntawm qhov ntev:xyuas kom meej tias qhov ntev ntawm sab thiab phab ntsa tuab poob rau hauv tus qauv teev tseg.
Qhov zoo ntawm vuam (cov kav dej vuam):xyuas seb puas muaj kab nrib pleb, nkag tsis tiav, lossis lwm yam tsis zoo - kev kuaj ultrasonic yog ib txwm muaj.
Qhov xwm txheej ntawm qhov chaw:tsis muaj xeb ntau dhau, pitting, lossis tev tawm ntawm cov txheej galvanized.
Cov khoom siv kho tshuab:thov cov ntawv qhia txog kev sim zeb uas qhia txog lub zog tensile thiab yield, thiab ua cov kev kuaj qauv yog tias tsim nyog.
Cov Lus Qhia Txog Kev Xaiv
Khoom siv
Cov chaw sab nraum zoov lossis cov chaw ua xeb nyiam cov hlau galvanized lossis stainless hlau. Cov qauv uas muaj peev xwm nqa tau hnyav feem ntau xav tau cov hlau carbon uas tuab txaus rau phab ntsa.
Kev Loj
Xam qhov ntev ntawm sab thiab qhov tuab ntawm phab ntsa raws li cov khoom thauj tiag tiag. Kev tsim ntau dhau yuav ua rau nkim nyiaj; kev tsim tsawg dhau yuav ua rau muaj kev pheej hmoo rau kev nyab xeeb.
Daim Ntawv Pov Thawj
Xyuas kom tseeb tias cov khoom ua tau raws li cov qauv siv tau - ASTM qib tau txais kev lees paub dav hauv kev lag luam thoob ntiaj teb.
Thaum cov raj plaub fab yog qhov kev xaiv zoo
Cov qauv tsim uas tsis hnyav, kev tsim kho sai, thiab cov qauv geometry nyuaj txhua yam nyiam SHS.
Thaum twg yuav xav ob zaug
Cov ntawv thov siab heev lossis kub heev yuav xav tau cov raj tuab uas tsis muaj qhov txuas lossis cov hlau tshwj xeeb hloov chaw.
Cov Lus Qhia Txog Kev Txuag Nyiaj
Sivcov yeeb nkab welded squarerau cov khoom uas tsis muaj lub nra hnyav - lawv pheej yig dua 30–50% dua li cov khoom tsis muaj seamless.
Raucov ntawv thov sab hauv tsev, lub raj dub liab qab ntxiv rau cov xim pleev xim rau ntawm qhov chaw tuaj yeem zam tus nqi ntxiv ntawm kev galvanizing.
Yuav khoomqhov ntau thiab tsawg txheem(piv txwv li, 50 × 50 × 2.0 hli) — cov lus qhia tshwj xeeb yuav luag ib txwm muaj tus nqi siab dua.
