Dab tsi yog style vaj ntxwv?

Txheej txheem hlau tubing yog ib qeb ntawm txias txias - mi}}}}} - cov kabmob qauv qauv. Nws yog cov qauv zoo li hss (hollow cov qauv sib xyaw) thiab los ntawm peb lub zog (hss)} Multi {{{}} directal loads, thiab huv sitesthetic tsos.

Cov ntsiab lus yog ib qho kev tsis muaj me ntsis, tab sis cov yuam sij tseem ceeb hauv lawv lub hom phiaj npaj, tshuaj lom neeg, thiab cov khoom siv mechanical, thiab cov khoom siv.
Cov hlau qub: qhov no feem ntau yog hais txog qhov dav dav - hom phiaj carbon hlau. Nws yog ntau yam thiab siv ntau yam ntawm cov ntawv thov los ntawm nkhaus thiab cov thav ntawv rau cov khoom siv kev ntxhov siab uas tsis yog thawj qhov kev txhawj xeeb.
Cov hlau txheej txheem: Qhov no yog qeb ntawm cov hlau tshwj xeeb tsim rau load - cov kabmob, thiab yees. Thaum lub zog yog qhov tseem ceeb heev, nws kuj tseem yuav tsum muaj lwm cov khoom tsim kho cov khoom lag luam:

• Ua kom muaj zog dua: nws yuav tsum yuav khoov thiab deform tau ua ntau dhau los ua ntej ua tsis tiav (britle lov (britle bacture yog kev puas tsuaj rau cov qauv).
• Weldability: nws yuav tsum tau tsim kom yooj yim thiab ntseeg tau welded tsis muaj crittle nyob rau hauv tshav kub} kev kub ntxhov ntawm weld.
• Toubness: tshwj xeeb tshaj yog nyob rau hauv ib puag ncig txias, nws yuav tsum tawm tsam fracturing thaum cuam tshuam.
• Cov Khoom Siv: Nws tsim los ntau stricter tshuaj thiab thev naus laus zis thev naus laus zis kom ntseeg tau tias kev ua tau zoo hauv qab.

Cov pipes feem ntau yog siv rau cov kev siv cov qauv tsim yog tsim rawsASTM A500Txheem, uas yog tus qauv kev qhia tshwj xeeb rau cov sibcham, xwmfab, thiab duab plaub txias {}} mive welbon steel hlau qauv kav hlau
Cov yam ntxwv ntawm Astm A500 tus qauv:

• Zoo rau cov qauv: nws tau tsim tshwj xeeb rau load - Cov Khoom Siv Cov Khoom Siv Txhua Lub Zog, Tensile Lub Zog, thiab Ductility.
• Tus nqi -}}} Ua tau zoo: nws cov txheej txheem tsim khoom ua rau nws xaiv tau tshaj plaws rau cov txheej txheem kev teeb tsa.
• Zoo zog -} rau - qhov hnyav sib piv: Hollow Saccture muaj zog thiab txhav thaum muaj qhov hnyav.
• Weldability: cov tshuaj lom neeg muaj pes tsawg leeg raug tswj kom ntseeg tau tias nws tuaj yeem yooj yim thiab ntseeg tau welded.
• Cov Qib Kawm: Nws los hauv ob peb qib, nrog A500 qib B thiab qib A500 C CEG ua qhov feem ntau. Qib C muaj me ntsis siab dua li muaj zog.

Tsis yog los ntawm lub neej ntawd. Teem sijhawm 40 yog phab ntsa tuab tsim rau cov yeeb nkab tsim kom cov qauv siab zoo liASTM A53.
ASTM A53 Yeeb Nkab: Tsim los tuav lub siab. Nws cov khoom thiab kev soj ntsuam yog tsom rau kev muaj kua tsis muaj xau.
ASTM A500 HSS: tsim los nqa cov qauv txheej txheem. Nws cov khoom tau tsom mus rau lub zog, txhav txhav, thiab ductility.
Tuaj yeem teem sijhawm 40 A53 cov yeeb nkab siv rau hauv cov ntawv thov kev lag luam?

Yog lawm, feem ntau nws siv rau cov ntawv thov yooj yim zoo li laj kab lus, Handrails, lossis tsis {{khab-tseem ceeb txhawb. Txawm li cas los xij, rau ib qho engineered, thauj - tus kws tshaj lij yuav qhia tau ib lub tsev lossis tus choj yuav tau lees paub, paub tseeb, thiab ua kom zoo rau lub hom phiaj ntawd.

Cov yeeb nkab txheej txheem (ntau dua hu ua hollow cov teeb tsa lossis hss) tuaj yeem siv los yog welded, tab sis feem coob siv hauv kev tsim tsa yog welded.
Thaum cov txheej txheem seamolal tubing muaj tshwm sim, tshaj li 95% ntawm cov txheej txheem kev teeb tsa (hss) siv nyob rau hauv cov tuam tsev, cov choj, thiab cov thav duab yog welded, tsis yog dab tsi. Cov txheej txheem vuam tau siv yog li ntawd txoj kev khi yog qhov muaj zog raws li tus niam txiv hlau, ua kom nws zoo txig rau yuav luag txhua cov ntawv thov.

Tseem Ceeb Takaway: Qhov tseem ceeb tshaj plaws tsis yog seb lub raj muaj lub leeg muaj rau cov qauv txheej txheem kev teeb tsa, feem ntau as u as u.

Txheej txheem tub sab yog ubiquitous hauv kev tsim kho niaj hnub vim nws txoj kev ua tau zoo thiab huv.

• Tsev thav ntawv thav ntawv: Raws li kab thiab kab teeb hauv tsev lag luam.
• Trusses: cov tswvcuab ntawm lub ru tsev thiab choj trusses.
• Chaw thav duab & domes: complex, ntev -} span cov qauv zoo li cov nyob hauv tshav dav hlau thiab arenas.
• Txuas hniav: Tshwj xeeb yog neeg taug kev thiab txuas hniav txuas hniav.
• Cov ntsiab lus Architectural: Cov kab mob, ntaiv, tes ua, canopies, thiab duab puab.
• Kev lag luam Industrial: txhawb nqa cov khoom siv, mezzanines, thiab cov tshuab cia.
• Lub tsheb thav ntawv: Yob tawb rau cov tsheb sib tw thiab cov thav ntawv rau cov tsheb thauj khoom thiab cov tsheb npav.
