Cov kav dej dubyog cov tsis-galvanized steel kav. Cov yeeb nkab dub, lub npe hu ua scaly, tsaus hlau oxide txheej ntawm nws qhov chaw. Nws yog siv nyob rau hauv daim ntawv thov uas tsis xav tau galvanized steel.
Tom qab siv ib qho me me ntawm cov khoom haum rau cov xov, lawv tau threaded rau hauv cov yeeb nkab threaded. Cov kav dej loj dua yog welded, tsis threaded. Dub steel yeeb nkab yog txiav nrog lub luag haujlwm hnyav yeeb nkab cutter, chop saw lossis hacksaw. Koj tuaj yeem tau txais cov hlau me me ERW cov kav dej dub, dav siv rau cov pa xa tawm sab hauv thiab sab nraud hauv tsev, thiab rau cov dej kub hauv cov tshuab boiler. Kuj tseem siv tau rau cov dej haus los yog cov dej ntws los yog cov kav dej tso tawm. Xauj los ntawm peb Cov Khoom Siv Hluav Taws Xob thiab Tube Catalog txhawm rau nrhiav tus neeg xa khoom uas ua tau raws li koj xav tau. Dub steel yeeb nkab yog siv rau cov ntawv thov uas tsis tas yuav galvanizing cov yeeb nkab. Qhov no tsis yog-galvanized dub steel yeeb nkab muaj npe rau nws cov hlau oxide tsaus nti ntawm nws qhov chaw. Vim yog lub zog ntawm cov yeeb nkab steel dub, nws yog siv los xa cov nkev thiab dej mus rau cov chaw nyob deb nroog, nrog rau kev tiv thaiv cov xaim hluav taws xob thiab cov kav dej rau kev xa cov cua kub thiab cua. Kev lag luam roj kuj tseem siv cov kav dej dub los thauj cov roj ntau mus rau thaj chaw deb.

Cov kav hlau dub thiab cov raj tuaj yeem raug txiav thiab threaded kom haum rau koj qhov project. Fittings rau hom yeeb nkab no yog dub malleable (mos) cam khwb cia hlau.

Txoj kev loj hlob ntawm cov kav hlau dub

Whitehouse txoj kev tau ua kom zoo dua los ntawm John Moon hauv xyoo 1911. Nws thev naus laus zis ua rau cov tuam txhab tsim cov kav dej txuas ntxiv mus. Nws siv nws cov thev naus laus zis los tsim cov tshuab thiab ntau cov chaw tsim khoom tau txais nws. Tom qab ntawd tuaj qhov kev xav tau ntawm seamless hlau kav. Seamless raj yog Ameslikas tsim los ntawm drilling qhov nyob rau hauv nruab nrab ntawm ib lub tog raj kheej. Txawm li cas los xij, nws yog qhov nyuaj rau kev xyaum nrog cov precision yuav tsum tau ua kom cov phab ntsa thickness uniformity. Ib qho kev txhim kho xyoo 1888 tau nce kev ua tau zoo los ntawm kev ua cov pob zeb nyob ib ncig ntawm cov hluav taws kub-resistant cib cores. Tom qab txias, tshem tawm lub cib, tawm hauv ib lub qhov rau hauv nruab nrab.

Kev siv cov yeeb nkab dub

Lub zog ntawm cov yeeb nkab dub ua rau nws zoo tagnrho rau kev xa dej thiab cov pa roj hauv cov chaw nyob deb nroog thiab nroog, nrog rau kev tiv thaiv cov xaim hluav taws xob thiab cov kav dej uas nqa lub zog siab thiab cua. Cov kav hlau dub yog siv los ntawm kev lag luam roj thiab roj av los thauj cov roj ntau mus rau thaj chaw deb. Qhov no tau txais txiaj ntsig vim tias cov yeeb nkab steel dub yuav tsum tau saib xyuas me ntsis. Lwm yam kev siv rau cov kav hlau dub muaj xws li kev faib roj hauv tsev thiab sab nraum tsev, qhov dej thiab cov kav dej phwj tuaj. Cov kav hlau dub yeej tsis siv los thauj dej haus.

Niaj hnub craftsmanship ntawm dub steel kav

Kev nce qib hauv kev tshawb fawb tau zoo heev txhim kho lub pob tw-welded yeeb nkab ua txoj kev tsim los ntawm Whitehouse. Nws cov txheej txheem tseem yog thawj txoj hauv kev ua cov kav dej, tab sis cov cuab yeej tsim khoom niaj hnub no uas tuaj yeem tsim kom muaj qhov kub thiab txias siab heev ua rau cov yeeb nkab tsim tau zoo dua. Nyob ntawm lawv txoj kab uas hla, qee cov txheej txheem tuaj yeem tsim cov yeeb nkab welded ntawm qhov xav tsis thoob ntawm 1,100 ko taw ib feeb. Nrog rau qhov nce loj ntawm cov khoom siv steel kav, qhov zoo ntawm cov khoom kawg kuj tau txhim kho.

Kev Tswjhwm Zoo ntawm Dub Hlau Yeeb Nkab

Kev tsim cov cuab yeej tsim khoom niaj hnub no thiab kev tsim cov khoom siv hluav taws xob tau ua rau muaj kev txhim kho tseem ceeb hauv kev ua haujlwm thiab kev tswj kom zoo. Cov tuam txhab lag luam niaj hnub siv cov kev ntsuas X-ray tshwj xeeb kom ntseeg tau tias cov phab ntsa tuab. Lub zog ntawm lub raj yog sim nrog lub tshuab uas ua rau lub raj ntim dej hauv qab kev kub siab kom ntseeg tau tias lub raj yog tuav hauv qhov chaw. Cov kav dej ua tsis tiav yuav raug muab pov tseg.

Dab tsi yog qhov txawv ntawmcev dubthiabgalvanized steel yeeb nkab

Galvanized hlau

Kev siv lub ntsiab ntawm cov yeeb nkab galvanized yog thauj cov dej mus rau cov tsev thiab cov tsev lag luam. Zinc tseem tiv thaiv kev tsim cov pob zeb hauv av uas tuaj yeem txhaws cov kav dej. Galvanized kav feem ntau yog siv los ua scaffolding thav duab vim lawv cov corrosion kuj.

cev dub

Cov yeeb nkab dub yog txawv ntawm cov yeeb nkab galvanized vim nws tsis muaj txheej txheej. Cov xim tsaus yog los ntawm cov hlau oxide uas tsim rau ntawm nws qhov chaw thaum lub sijhawm tsim khoom. Qhov tseem ceeb ntawm kev siv cov kav hlau dub yog thauj cov propane lossis cov pa roj carbon monoxide mus rau cov tsev nyob thiab cov tsev lag luam. Cov yeeb nkab yog tsim los tsis muaj seams, ua rau nws zoo dua rau kev thauj cov pa roj. Cov yeeb nkab dub kuj tseem siv rau hauv cov tshuab tua hluav taws vim tias nws muaj hluav taws ntau dua li cov yeeb nkab galvanized.

Taw qhia txog qhov txawv

• Ob lub kav dej dub thiab galvanized yog ua los ntawm cov hlau.
• Galvanized kav dej muaj zinc txheej, thaum cov kav dej dub tsis muaj
• Vim tias nws yooj yim rau corrode, cov kav dej dub yog qhov tsim nyog rau kev xa cov roj. Ntawm qhov tod tes, cov kav dej galvanized yog qhov zoo tshaj plaws rau kev nqa dej, tab sis tsis muaj hmoo
• Galvanized kav yog kim dua vim lawv muaj zinc txheej
• Galvanized yeeb nkab yog ntau ruaj

Dej thiab roj yuav tsum tau xa mus rau cov tsev nyob thiab cov tsev lag luam. Natural gas powers qhov cub, dej rhaub thiab lwm yam khoom siv, thaum dej yog qhov tseem ceeb rau lwm tus neeg xav tau kev pab. Ob hom yeeb nkab feem ntau siv los thauj dej thiab roj yog cov kav hlau dub thiab cov kav hlau galvanized.

Teeb meem
Cov zinc ntawm cov kav dej galvanized tuaj yeem tawg dhau sijhawm, txhaws cov kav dej. Spalling tuaj yeem ua rau cov yeeb nkab tawg. Kev siv cov kav dej galvanized los thauj cov roj tuaj yeem ua rau muaj kev phom sij. Ntawm qhov tod tes, cov kav hlau dub corrode yooj yim dua li cov kav dej galvanized thiab cia cov ntxhia los ntawm cov dej los tsim hauv lawv.

Nqi
Galvanized steel kav raug nqi ntau dua cov kav hlau dub vim tias kev tsim cov kav dej galvanized suav nrog cov txheej txheem galvanizing thiab kev tsim khoom. Galvanized fittings kuj raug nqi ntau dua li cov siv ntawm cov hlau dub. Galvanized steel kav yuav tsum tsis txhob txuas nrog cov kav hlau dub thaum lub sij hawm tsim kho vaj tse lossis kev lag luam.

Dab tsi yog qhov txawv ntawm astm a53 thiab astm a106?
Qhov txawv ntawmASTM A53 TubethiabA106 cevnyob rau hauv cov nqe lus ntawm specification ntau, yeeb nkab tshuaj muaj pes tsawg leeg, txhua yam khoom (tensile thiab yield zog, thiab lwm yam), yeeb hom.

thaj tsam

• ASTM A53 yog tus qauv tshwj xeeb rau cov yeeb nkab, hlau, dub thiab kub dipped, galvanized, welded, thiab seamless.
• ASTM A106 yog tus qauv tshwj xeeb rau seamless carbon steel yeeb nkab rau kev pabcuam kub.

Daim Ntawv Thov Hom A 53钢管
tuaj yeem yog welded lossis seamless, nyob ntawm seb nws tau yuav li cas. Nws yog cov yeeb nkab steel dav dav, suav nrog cov yeeb nkab galvanized thiab cov yeeb nkab dub.
A106 yog cov yeeb nkab zoo sib xws tab sis rau kev pabcuam kub siab (txog 750 degrees Fahrenheit). Nws yog seamless raj.
Hauv Teb Chaws Asmeskas tsawg kawg, welded yeeb nkab feem ntau muaj A53, thaum A106 yog seamless. Yog tias koj thov A53 hauv Asmeskas, lawv yuav suav A106 ua lwm txoj hauv kev.
Tshuaj muaj pes tsawg leeg
Piv txwv li, thaum peb piv A106-B thiab A53-B seamless los ntawm cov tshuaj muaj pes tsawg leeg foundations, peb pom:

• 1. A106-B muaj silicon, yam tsawg kawg nkaus. 0.10%, ntawm uas A53-B yog 0%, silicon yog ib qho tseem ceeb rau kev txhim kho cov txheej txheem cua sov.
• 2. A106-B muaj manganese 0.29-1.06%, uas A53-B yog 1.2%.
• 3. A106-B muaj cov sulfur thiab phosphorus tsawg, max. 0.035%, uas A53-B muaj 0.05 thiab 0.045%, feem.

Lwm qhov sib txawv ntawm A53 yeeb nkab thiab A106 yeeb nkab
Vim tias lawv muaj ntau yam sib txawv thiab qhia ntau hom kev sib txawv ntawm cov kav dej steel, cov txheej txheem tsim khoom thiab yuav tsum muaj kev tswj xyuas zoo thiab kev tshuaj xyuas yuav txawv ntawm ib leeg. Yog tias koj muaj kev xav tshwj xeeb, thov tawm lus.
