SquareTubeyog ib hom hlau yeeb nkab uas muaj ib tug square lossis rectangular cross-sectional duab. Hauv kev tsim khoom, square tubes tau siv dav hauv kev tsim kho, kev tsim khoom, kev tsim tsheb thiab lwm yam. Kev siv tshuab ntawm cov raj square muaj qhov cuam tshuam rau qhov zoo thiab kev ua haujlwm ntawm cov khoom.

Square Tube feem ntau siv rau txhua kab, Square Tubes feem ntau hu ua "box sections". Ib qho piv txwv yog 100 x 100 x 10 SHS, uas yog 100 hli tob, 100 hli dav thiab phab ntsa yog 10 hli tuab. Zoo ib yam li Rectangular Tubes, kub dov Square Tubes yog ua nyob rau hauv lub zeb ua ib thooj, whereas txias tsim SHS yog ua los ntawm ib tug ca dov ntawm txoj cai kaum thiab welded. Yog li ntawd nws yog ib qho yooj yim kom nco ntsoov qhov txawv, raws li cov txias dov Square Tubes muaj ib tug weld tag nrho raws li lawv ntev.

Square tube ua technology

Kev siv thev naus laus zis ntawm cov raj square muaj xws li blanking, ntug kev, sib sau, vuam, straightening, trimming, plaub hau tshem tawm, tiv thaiv xeb thiab lwm yam txuas. Thawj kauj ruam yog txiav cov khoom siv raw steel phaj lossis steel kauj raws li qhov xav tau loj kom tau txais lub raj square ntawm qhov ntev yuav tsum tau ua. Thaum lub sij hawm ua cov txheej txheem, cov npoo ntawm cov square tubes tau ua tiav los ntawm kev txiav, grooving, edging thiab lwm yam txheej txheem los xyuas kom meej qhov flatness thiab qhov tseeb ntawm cov npoo.

Ntxiv nrog rau cov txheej txheem ua haujlwm saum toj no, cov kav dej square kuj yuav tsum tau xeb-pov thawj kom ntev lawv lub neej kev pab cuam. Cov txheej txheem los tiv thaiv xeb feem ntau suav nrog kev txau cov xim pleev xim, kub-dip galvanizing, chrome plating, thiab lwm yam. Txau cov xim tiv thaiv xeb yog txhawm rau txau cov xim pleev xim rau saum npoo ntawm cov yeeb nkab square kom cais cov huab cua thiab dej. thiab tiv thaiv cov yeeb nkab square los ntawm xeb. Kub-dip galvanizing yog rau immerse square kav nyob rau hauv molten zinc kua los tsim ib txheej ntawm zinc los tiv thaiv xeb. Chrome plating yog txheej txheej ntawm lub raj square nrog ib txheej ntawm chromium los txhim kho corrosion kuj ntawm square raj.

Thaum lub sij hawm ua cov square raj, koj yuav tsum tau them sai sai rau cov ntsiab lus hauv qab no. Ua ntej ntawm tag nrho cov, qhov ua tiav qhov ntev thiab kam rau ua yog nruj me ntsis tswj kom ntseeg tau tias qhov tseeb qhov tseeb ntawm lub raj square. Thib ob, xyuam xim rau kev tiv thaiv qhov chaw ntawm lub raj square thaum ua haujlwm kom tsis txhob khawb lossis puas tsuaj. Thib peb, cov pob qij txha welded yuav tsum tau kuaj xyuas kom paub tseeb tias qhov zoo thiab lub zog ntawm cov welds. Thaum kawg, xaiv cov khoom tsim nyog thiab kev siv thev naus laus zis raws li qhov sib txawv ntawm kev siv lub raj square.

Kev siv tshuab ntawm cov raj square yog qhov tseem ceeb rau qhov zoo thiab kev ua haujlwm ntawm cov khoom. Tsuas yog los ntawm kev tshawb fawb thiab tsim nyog ua tshuab tuaj yeem tsim cov khoom lag luam square nrog zoo heev thiab meej qhov ntev. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them rau kev tiv thaiv qhov chaw ntawm lub raj square thaum ua haujlwm kom tsis txhob muaj kev puas tsuaj thiab xeb.
