Lub rooj yog kev kwv yees siv. Qhov hnyav tiag tiag nyob ntawm qhov khoom xa tuaj, tso cai kam rau ua thiab qhov hnyav.

Square Stainless Hlau Tube Qhov hnyav

Rau ib qho zoo tagnrho square seem nrog ntse sab hauv thiab sab nraud ces kaum, rho tawm sab hauv hollow cheeb tsam los ntawm sab nraud square cheeb tsam.

Square Hlau Cheeb Tsam

A = B² − (B − 2t)²

A = 4t × (B − t)

304 Simplified Formula

kg/m ≈ 0.03160 × t × (B − t)

kg/m ≈ 0.01580 × t × (W + H − 2t)

Piv txwv:50 × 25 × 1.5 hli 304 lub voj voos tubing muab qhov kev xav tau zoo tshaj qhov hnyav ntawm kwv yees li1.706 kg / m, los yog txog10.24 Kgrau 6m.

Sharp -cov qauv qauv yog qhov tseem ceeb rau kev kwv yees thawj zaug. Cov ntxhuav los yog cov duab kos yuav tsum tau siv thaum lub kaum sab xis thiab cov seem geometry muaj feem cuam tshuam rau qhov kev txiav txim.

Theoretical Nyhav vs Qhov Tiag Tiag

Ib qho qauv tsim nyog tseem tuaj yeem tsim cov txiaj ntsig sib txawv ntawm qhov ntsuas ntsuas vim tias cov qauv siv qhov ntev uas tau hais tseg thaum lub raj tiav lawm nyob rau hauv kev tsim khoom.

Phab ntsa Variation

Nominal phab ntsa yuav txawv nyob rau hauv qhov kev tso cai kam rau ua. Yam tsawg kawg nkaus -cov khoom siv phab ntsa yuav xav tau lub hom phiaj tsim khoom ntau dua.

OD Variation

Kev xa tawm sab nraud tuaj yeem txawv me ntsis ntawm tus nqi kos npe nominal thaum tseem siv tau.

Khaub ncaws Geometry

Square thiab rectangular tube ces kaum yog sib npaug es tsis yog lej ntse, hloov qhov tseeb seem cheeb tsam.

Weld condition

Sab hauv lossis sab nraud weld reinforcement tuaj yeem ntxiv me me ntawm cov khoom piv nrog rau qhov zoo tagnrho.

Ntev Ntev

Qhov tseeb daim ntev tuaj yeem sib txawv ntawm qhov nominal txiav ntev thiab ncaj qha hloov qhov ntsuas qhov hnyav.

Txheej Txheej

Sib tsoo, polishing, machining thiab pickling tuaj yeem tshem tawm cov khoom me me ntawm cov khoom tiav.

Tsis txhob sib piv cov lus siv qhov hnyav sib txawv

Ib tus neeg muag khoom tuaj yeem hais los ntawm qhov ntsuas qhov ntsuas ntsuas los ntawm qhov ntsuas nominal, thaum lwm tus tuaj yeem hais los ntawm qhov tseeb zeb qhov hnyav. Tus nqi tsev yuav tshwm sim qis dua lossis siab dua txawm tias tag nrho cov nqi xa khoom zoo sib xws.

Ua ntej muab cov kev sib piv, paub meej tias cov lus hais yog raws li kev xav tau ntawm kilograms, qhov tseeb kilograms, tus nqi tas li lossis tag nrho cov nqi txiav txim.

Yam tsawg kawg nkaus phab ntsa thiab Nominal Phab ntsa cuam tshuam qhov hnyav li cas

Lub hauv paus ntawm phab ntsa txiav txim siab seb lub thickness tau txhais li cas. Qhov no tuaj yeem hloov pauv ob qhov kev cia siab ntawm phab ntsa thiab qhov hnyav xa tawm tiag tiag.

Yam tsawg kawg nkaus -Wall Order

Cov phab ntsa tau teev ua raws li kev txiav txim qis dua

Cov chaw tsim khoom yuav xav tau lub hom phiaj ntawm phab ntsa tuab dua kom tso cai rau kev ntsuas hauv zos tsis poob qis dua qhov yuav tsum tau ua tsawg kawg nkaus. Yog li ntawd, qhov tseeb chav ntsuas qhov hnyav yuav siab dua li kev suav yooj yim siv tus nqi qis kawg nkaus.

Nominal - Phab ntsa Order

Cov phab ntsa tau teev yog tus nqi nominal

Kev nyeem phab ntsa tiag tiag yuav yog siab dua lossis qis dua tus nqi nominal hauv qhov tso cai kam rau ua. Qhov hnyav xa tuaj tuaj yeem txawv ntawm qhov nominal theoretical xam.

Txoj Cai Muag Khoom

Qhia lub hauv paus ntawm phab ntsa ua ntej thov kom lav tag nrho qhov hnyav. Tib tus lej phab ntsa tuab tuaj yeem sawv cev rau cov khoom sib txawv thiab sib txawv tonnage.

Kwv yees stainless hlau kauj ntev los ntawm qhov hnyav

Thaum lub raj txuas txuas mus rau hauv cov coils, kwv yees qhov ntev tuaj yeem kuaj xyuas los ntawm kev faib cov khoom hnyav los ntawm kev ntsuas qhov hnyav ib meter.

Kwv yees lub kauj ntev=net tube nyhav ÷ theoretical kg/m

Tshem Cov Ntim Ntim

Tsis txhob siv tag nrho pallet, reel, steel-thav duab lossis ntoo- rooj plaub raws li cov khoom hnyav.

Tshawb xyuas phab ntsa

Siv cov phab ntsa nominal hauv cov qauv yuav ua rau qhov sib txawv ntawm qhov ntev ntawm qhov ntsuas ntawm phab ntsa.

Siv Length Records

'meter'-cov ntaub ntawv txee, coil cim npe thiab cov cav tsim khoom muab cov ntawv cog lus muaj zog dua li rov qab suav ib leeg.

Net Nyhav, Tag Nrho Nyhav thiab Chargeable Nyhav

Cov nqe lus no yuav tsum tau muab cais tawm thaum npaj cov ntawv xa tawm lossis cov npe ntim khoom.

Theoretical Nyhav

Muab xam los ntawm qhov pom zoo qhov ntev, qhov ntom ntom thiab ntau yam tsis hnyav txhua daim tiav.

Qhov hnyav Net tiag

Ntsuas qhov hnyav ntawm cov khoom siv hlau stainless, tsis suav nrog cov rooj plaub, pallets, thav duab thiab lwm yam khoom ntim.

Qhov hnyav tag nrho

Ua ke qhov hnyav ntawm cov hlab thiab tag nrho cov ntim export, kev txhawb nqa, reels, crates, pallets thiab cov ntaub ntawv tiv thaiv.

Freight ceeb toom:Kev npaj kev xa khoom tuaj yeem raug txwv los ntawm pob qhov ntev, nqa cov ntsiab lus, ntim hauv qhov chaw, pob khoom thiab kev nyab xeeb kev thauj khoom - tsis yog los ntawm tag nrho cov kilograms.
