Xov Xwm - Nkag Siab Txog Qhov Txawv Ntawm ERW, SSAW, thiab DSAW Steel Pipes

Cov kav hlau ua lub luag haujlwm tseem ceeb hauv kev tsim kho vaj tse ntawm lub neej niaj hnub no los ntawm cov kav dej roj thiab roj mus rau kev xa dej thiab kev siv cov qauv. Ntawm lawv, qhov nrov tshaj plaws yogERW vuam yeeb nkab, SSAW yeeb nkab hlau, DSAW yeeb nkab hlauKev paub txog qhov sib txawv ntawm cov khoom no ua rau cov engineers, cov neeg cog lus thiab cov neeg yuav khoom xaiv cov yeeb nkab zoo tshaj plaws rau lawv cov ntawv thov.

ASTM A671 CC65 CL 12 EFW Cov Kav Hlau Rau Kev Lag Luam & Cov Qauv Siv (1)

ERW Steel Yeeb Nkab yog dab tsi?

ERW yeeb nkab hlauhais txog cov yeeb nkab hlau uas tau tsim los ntawm kev siv hluav taws xob tsis kam vuam. Qhov no ua rau muaj cov xov ntev raws li qhov ntev ntawm cov yeeb nkab.

Cov hauv qab no yog qee qhov tseem ceeb ntawm cov kav dej ERW:
Txoj kab uas hlaMe mus rau nruab nrab (feem ntau yog 10 mm - 508 mm).
Phab ntsa tuabNyias mus rau nruab nrab (qhov tuab ib txwm ≤20 hli).
Cov ntawv thovRau cov kav dej, cov kav roj, thiab cov khoom siv thiab cov khoom siv kho tshuab.
Cov txiaj ntsig: Qhov tseeb ntawm qhov ntev, qhov du sab hauv, pheej yig.
Kev txwvTsis siv tau rau kev pabcuam siab heev.

SSAW Yeeb Nkab Hlau yog dab tsi?

SSAW (Kauv Submerged Arc Welded)yeeb nkab hlau, tseem hu ua HSAW, yog ua los ntawm kev dov ib daim hlau mus rau hauv ib lub kauv thiab vuam cov seam siv submerged arc welding.

Cov yam ntxwv tseem ceeb ntawm cov kav dej SSAW:
Txoj kab uas hlaNruab nrab mus rau loj heev (400 mm–3600 mm+).
Phab ntsa tuabNyias mus rau nruab nrab (≤25 hli feem ntau).
Txoj xov: Kauv sib txuas ntawm lub kaum sab xis rau lub axis ntawm cov yeeb nkab.
Cov ntawv thovCov kav dej roj thiab roj av, kev thauj mus los hauv dej, cov haujlwm loj.
Cov txiaj ntsig: Muaj peev xwm tsim cov kab uas loj thiab cov phab ntsa tuab.
Cov kev txwv: Cov yeeb nkab kauv sib dhos me ntsis txo qhov muaj zog siab piv rau cov yeeb nkab DSAW ntev.

DSAW Steel Pipe yog dab tsi?

DSAW yeeb nkab hlau (Ob Chav Submerged Arc Welded)zoo ib yam liLSAW (Longitudinal Submerged Arc Welded) yeeb nkabuas yog ua los ntawm kev khoov cov hlau phaj ~ 1/2 nti txog 3 nti tuab rau hauv lub tog raj kheej thiab vuam ob qho tib si sab hauv thiab sab nraud siv cov txheej txheem vuam submerged arc.

Cov yam ntxwv tseem ceeb ntawm DSAW yeeb nkab:
Txoj kab uas hlaNruab nrab mus rau loj (300–2500 mm tus qauv).
Thickness ntawm phab ntsaNruab nrab mus rau tuab (≥6 hli txog 50 hli+).
Siv: Cov kav dej roj thiab roj av siab thiab cov kav dej hiav txwv, cov ntawv thov kev tsim kho uas xav tau lub zog siab.
Cov txiaj ntsig: Cov seams muaj zog thiab txhim khu kev qha, ua rau cov khoom siv zoo tagnrho rau cov xwm txheej siab.
Qhov tsis zoo: Kev tsim khoom kim heev thiab cov txheej txheem tsim khoom qeeb dua piv rau ERW thiab SSAW.

Cov kev pabcuam ntawm Tuam Tshoj Royal Steel Group

Tuam Tshoj Royal Steel Groupyog ib lub chaw tsim khoom siv hlau yeeb nkab nrog ERW (Fais Fab Tiv Thaiv Welded), SSAW (Spiral Submerged Arc Welded) thiab DSAW (Double Submerged Arc Welded) cov yeeb nkab hlau thiab lwm yam. Raws li ntau xyoo ntawm kev paub hauv kev lag luam, lub tuam txhab muab kev sab laj thiab cov lus qhia tag nrho ntawm hom yeeb nkab tsim nyog tshaj plaws rau kev siv hauvKev xa roj thiab roj av, kev xa dej, kev ua haujlwm siab hauv kev lag luam, thiab cov haujlwm vascular, ntawm lwm yam kev siv.

Royal Steel Group xav txog ntau yam xws liqhov loj ntawm cov yeeb nkab, phab ntsa tuab, qib khoom siv, chav kawm siab, kev tiv thaiv corrosion, thiab cov xwm txheej ib puag ncigTxhawm rau txheeb xyuas cov kev daws teeb meem zoo tshaj plaws. Ntxiv mus, Tuam Tshoj Royal Steel Group muab kev pabcuam tsim khoom thiab kev pabcuam txheej txheem (piv txwv li tiv thaiv xeb, galvanization, epoxy lining) thiab kev ruaj ntseg zoo nrog tus qauv thoob ntiaj teb ntawm ASTM, ISO thiab API.

Los ntawm kev tsim khoom siab heev, kev sim ua kom raug thiab kev txhawb nqa kev xa khoom, lub tuam txhab muaj peev xwm muab cov khoom yeeb nkab hlau uas ua raws li cov qauv kev nyab xeeb, kev ruaj khov thiab kev ua tau zoo, uas ua rau cov neeg siv khoom xa cov kev daws teeb meem hauv paus tsev pheej yig, ruaj khov, thiab zoo.

Kev xaiv cov yeeb nkab hlau zoo nyob ntawm seb qhov project xav tau dab tsi, txoj kab uas hla, phab ntsa tuab, thiab qhov ntsuas siab:

Cov kav dej ERW: Tus nqi tsim nyog, zoo tagnrho rau cov kab uas me me mus rau nruab nrab thiab cov ntawv thov siab qis mus rau nruab nrab.

Cov kav dej SSAW: Haum rau cov kav dej loj uas muaj phab ntsa tuab.

Cov kav dej DSAW: Qhov kev xaiv zoo tshaj plaws rau kev siv siab, muaj zog xws li cov kav dej hiav txwv lossis roj & roj av.

Kev nkag siab txog qhov sib txawv ntawm ERW, SSAW, thiab DSAW cov kav hlau ua kom muaj kev ua tau zoo tshaj plaws, kev nyab xeeb, thiab kev siv nyiaj tsim nyog rau txhua qhov project hauv paus.
