Hollow steel kav yog cov kav hlau uas muaj lub voj voog (ntiv nplhaib- zoo li) lossis lwm cov duab kaw (xws li square, rectangular, elliptical, thiab lwm yam) hla -section, tag nrho hauv kev sib txuas nrog tsis muaj qhov khoom. Lawv cov yam ntxwv tseem ceeb yog lawv cov qauv hollow.
Cov yam ntxwv tseem ceeb:
Hollow Structure: Qhov no yog nws qhov tseem ceeb tshaj plaws, qhov txawv ntawm nws cov khoom steel tuav.
Khoom siv: Feem ntau yog ua los ntawm carbon steel, alloy steel, stainless hlau, thiab lwm yam, txiav txim siab nws cov khoom tseem ceeb xws li lub zog thiab corrosion kuj.
Cov duab:
Round Tube: Hom ntau tshaj plaws, nrog lub voj voos -section.
Square Tube: Nrog square cross-section.
Rectangular Tube: Nrog tus ntoo khaub lig-section.
Irregularly Shaped Tubes: Nrog ntoo khaub lig- ntu ntawm elliptical, rhomboid, hexagonal, lossis lwm yam duab tshwj xeeb.
Txheej txheem ntau lawm:
Feem ntau tsim los ntawm cov txheej txheem hauv qab no:
Seamless Steel Yeeb Nkab: Tsim los ntawm cov khoom steel hlau los ntawm kev tho thiab kub dov lossis kos duab txias, tsis muaj vuam seams. Feem ntau siv nyob rau hauv siab -siab, siab- zog, los yog precision daim ntawv thov.
Welded Steel Yeeb Nkab: Tsim los ntawm dov steel daim hlau los yog strips thiab ces welding lawv. Nyob ntawm cov txheej txheem vuam, muaj cov kav dej ncaj nraim welded (ERW, LSAW) thiab kauv welded kav (SSAW), thiab lwm yam. Lawv kuj pheej yig thiab siv dav.
Qhov zoo thiab kev siv:
Hollow steel kav, vim lawv cov qauv tshwj xeeb, muaj cov txiaj ntsig tseem ceeb hauv qab no, ua rau lawv siv dav hauv ntau qhov chaw:
Lub teeb yuag: Hauv tib tus ntoo khaub lig- ntu ntu (qhov muaj peev xwm thauj khoom), cov qauv hollow yog qhov sib zog dua li cov qauv khoom, txuag cov ntaub ntawv thiab txo cov nqi tsheb thauj mus los thiab kev teeb tsa.
High Strength / Good Stiffness (Bending and Torsional Resistance): Ib qho rationally tsim hollow cross-section (tshwj xeeb yog square thiab rectangular) muaj kev ua haujlwm siab hauv kev khoov thiab torsion. Cov khoom faib nyob rau hauv tus ntoo khaub lig- seem yog nyob deb ntawm lub hauv paus axis, ua rau lub sij hawm loj ntawm inertia.
Kev lag luam zoo: txuag cov ntaub ntawv thiab txo cov nqi raw khoom.
Kev thauj mus los: Lub ntuj hollow channel ua rau nws zoo tagnrho rau kev thauj cov kua, gases, hmoov, thiab lwm yam khoom (xws li dej, roj, roj, thiab chav). Kev them nyiaj yug tus qauv: Siv dav hauv kev tsim vaj tsev (xws li scaffolding, steel qauv kev cob qhia, txuas hniav), cov khoom siv kho tshuab (xws li cov khoom siv thav duab, tsav lub tog raj kheej, hydraulic thooj voos kheej kheej), kev tsim tsheb (tsheb chassis, tsheb kauj vab thav duab), rooj tog zaum ( rooj thiab lub rooj zaum thav duab), thiab lwm yam, raws li kev thauj khoom -cov kabmob lossis cov khoom txhawb nqa.
Kev Ua Haujlwm: tuaj yeem siv los ua kev tiv thaiv sheathing (conduit) rau cov xov hlau hluav taws xob thiab cables.
Kev Siv Kho Kom Zoo Nkauj: Cov kav hlau stainless thiab cov kav hlau coated feem ntau yog siv los ua cov khoom zoo nkauj xws li railings, handrails, thiab qhov rooj thiab qhov rais thav ntawv.
Kub Exchanger Tubes: Siv nyob rau hauv cov khoom xws li boilers thiab tshav kub exchangers.
Hom Kev Taw Qhia
Hollow Steel Yeeb Nkab: Feem ntau yog siv rau kev thauj khoom -cov kabmob cov kabmob, xav tau lub zog siab, nruj, thiab ruaj khov. Square thiab rectangular raj, thiab cov raj puag ncig feem ntau yog siv los tsim cov qauv hlau thiab cov khoom siv tshuab.
Fluid Transport Steel Pipes: Feem ntau yog siv rau kev thauj cov xov xwm, xav tau kev kub siab ua haujlwm, sealing, thiab corrosion kuj. Piv txwv xws li cov kav dej, cov kav dej roj, thiab cov kav dej roj. Seamless kav thiab welded kav uas yuav tsum tau siab (xws li LSAW) feem ntau siv ntawm no.
Cov kav hlau rau cov tshuab: Siv rau hauv kev tsim cov khoom siv kho tshuab, xws li lub tes tsho bearing thiab hydraulic lub tog raj kheej chim. Cov kev xav tau siab yog muab tso rau ntawm qhov tseeb qhov tseeb, qhov chaw tiav, thiab cov khoom sib xws. Txias- kos (dov) precision seamless steel kav feem ntau siv.
Kho kom zoo nkauj stainless hlau kav: Muaj qhov zoo ntawm qhov kawg thiab corrosion kuj, siv nyob rau hauv architectural kho kom zoo nkauj, khoom siv hauv tsev, thiab lwm yam.
