A106grb seamless steel yeeb nkab chaw tsim tshuaj paus

Cov yeeb nkab steel tsis yog tsuas yog siv rau kev xa cov kua dej thiab cov hmoov av, sib pauv cov hluav taws xob hluav taws xob, tsim cov khoom siv kho tshuab thiab cov thawv ntim khoom, tab sis kuj yog kev lag luam hlau. Siv cov yeeb nkab steel los ua cov kab sib txuas hauv tsev, ncej thiab cov cuab yeej txhawb nqa tuaj yeem txo qhov hnyav, txuag hlau los ntawm 20 ~ 40%, thiab paub txog kev tsim kho thiab kev tsim kho tshuab. Kev tsim cov kav hlau loj nrog cov kav hlau tsis tuaj yeem tsuas yog txuag cov hlau thiab ua kom yooj yim rau kev tsim kho, tab sis kuj txo qis thaj tsam ntawm kev tiv thaiv txheej thiab txuag peev thiab kho cov nqi.
Los ntawm txoj kev tsim khoom

Cov kav hlau tuaj yeem muab faib ua ob pawg raws li kev tsim khoom: seamless steel kav thiab welded steel kav. Welded steel kav yog hu ua welded kav rau luv luv.

1. Seamless steel yeeb nkab yuav muab faib ua kub dov seamless yeeb nkab, txias drawn yeeb nkab, precision steel yeeb nkab, kub expanded yeeb nkab, txias spinning yeeb nkab thiab extruded yeeb nkab raws li cov txheej txheem ntau lawm.

Bundles ntawm steel kav
Seamless steel yeeb nkab yog ua los ntawm high-quality carbon steel los yog alloy steel, uas yuav muab faib ua kub dov thiab txias dov (kos duab).

2.Welded steel yeeb nkab tau muab faib ua rau hauv qhov cub hluav taws xob welded yeeb nkab, hluav taws xob vuam (ua haujlwm vuam) yeeb nkab thiab tsis siv neeg arc welded yeeb nkab vim muaj txheej txheem vuam sib txawv. Vim muaj cov ntaub ntawv sib txawv, nws tau muab faib ua ncaj seam welded yeeb nkab thiab kauv welded yeeb nkab. Vim nws qhov kawg zoo, nws tau muab faib ua voj voog welded yeeb nkab thiab tshwj xeeb-puab (square, ca, thiab lwm yam) welded yeeb nkab.

Welded steel yeeb nkab yog ua los ntawm dov steel phaj welded los ntawm pob tw pob tw los yog kauv seam. Nyob rau hauv cov nqe lus ntawm kev tsim txoj kev, nws kuj tau muab faib ua welded steel yeeb nkab rau cov dej tsis tshua muaj siab kis tau tus mob, muab kauv seam welded steel yeeb nkab, ncaj dov welded steel yeeb nkab, welded steel yeeb nkab, thiab lwm yam. Seamless steel yeeb nkab yuav siv tau rau cov kua thiab roj pipelines. nyob rau hauv ntau yam kev lag luam. Cov kav dej welded tuaj yeem siv rau cov kav dej, cov kav dej, cov kav dej cua sov, cov kav dej hluav taws xob, thiab lwm yam.

Los ntawm cov khoom siv

Cov yeeb nkab steel tuaj yeem muab faib ua cov yeeb nkab carbon, hlau yeeb nkab, cov yeeb nkab steel hlau, thiab lwm yam raws li cov khoom siv yeeb nkab (xws li qib steel).

Cov pa roj carbon yeeb nkab tuaj yeem muab faib ua cov pa roj carbon zoo tib yam thiab cov yeeb nkab zoo carbon zoo.

Alloy yeeb nkab tuaj yeem muab faib ua: cov yeeb nkab uas tsis tshua muaj hlau, cov yeeb nkab steel hlau, cov yeeb nkab siab thiab cov yeeb nkab muaj zog. Cov kabmob yeeb nkab, kub thiab acid resistant stainless yeeb nkab, precision alloy (xws li kovar alloy) yeeb nkab thiab superalloy yeeb nkab, thiab lwm yam.

Welded steel yeeb nkab, tseem hu ua welded yeeb nkab, yog cov yeeb nkab steel welded nrog steel phaj lossis steel sawb tom qab crimping. Welded steel yeeb nkab muaj qhov zoo ntawm cov txheej txheem tsim khoom yooj yim, kev ua haujlwm siab ntau lawm, ntau yam thiab cov lus qhia tshwj xeeb thiab cov cuab yeej siv tsawg dua, tab sis nws lub zog dav dav yog qis dua li seamless steel yeeb nkab. Txij li thaum xyoo 1930, nrog rau kev txhim kho sai ntawm cov khoom siv zoo tshaj plaws thiab kev txhim kho ntawm vuam thiab tshuaj xyuas tshuab, cov vuam zoo tau raug txhim kho tas li, ntau yam thiab cov ntsiab lus ntawm welded steel kav tau nce, thiab seamless steel kav. tau hloov nyob rau hauv ntau thiab ntau teb. Welded steel kav yog muab faib ua ncaj welded yeeb nkab thiab kauv welded yeeb nkab raws li daim ntawv ntawm weld.

Longitudinal welded yeeb nkab muaj qhov zoo ntawm cov txheej txheem tsim khoom yooj yim, kev ua haujlwm siab ntau lawm, tus nqi qis thiab kev loj hlob sai. Lub zog ntawm kauv welded yeeb nkab feem ntau yog siab tshaj qhov ncaj welded yeeb nkab. Nws tuaj yeem tsim cov yeeb nkab welded nrog cov yeeb nkab loj dua nrog qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Txawm li cas los xij, piv nrog cov yeeb nkab ncaj seam nrog tib qhov ntev, qhov ntev vuam nce 30 ~ 100%, thiab qhov ceev ceev yog tsawg. Yog li ntawd, ncaj seam welding feem ntau yog siv rau me me-inch welded kav, thiab kauv vuam feem ntau yog siv rau loj-inch welded kav.

Welded steel yeeb nkab rau cov dej tsis tshua muaj siab kis tau tus mob (GB / t3091-2008) tseem hu ua cov yeeb nkab dav dav, feem ntau hu ua cov yeeb nkab dub. Nws yog welded steel yeeb nkab siv rau kev xa dej, roj, cua, roj, cua sov chav thiab lwm yam dej tsis tshua muaj siab thiab lwm yam. Phab ntsa thickness ntawm steel yeeb nkab kev twb kev txuas yog muab faib mus rau hauv zoo tib yam steel yeeb nkab thiab thickened steel yeeb nkab; Lub nozzle kawg tau muab faib ua cov yeeb nkab uas tsis yog threaded steel (cov yeeb nkab du) thiab threaded steel yeeb nkab. Lub welded steel yeeb nkab rau cov dej tsis tshua muaj siab tsis yog tsuas yog siv ncaj qha rau kev sib kis ntawm cov kua dej, tab sis kuj tau siv dav raws li cov yeeb nkab qub ntawm cov yeeb nkab galvanized welded steel yeeb nkab rau cov kua xa hluav taws xob tsawg.

1.Galvanized welded steel yeeb nkab rau cov dej tsis tshua muaj kev sib kis (GB / t3091-2008) tseem hu ua galvanized welded steel yeeb nkab, feem ntau hu ua cov yeeb nkab dawb. Nws yog qhov kub-dip galvanized welded (lub qhov cub vuam lossis hluav taws xob vuam) steel yeeb nkab siv rau kev xa dej, roj, roj cua, cua sov chav, dej cua sov thiab lwm yam dej tsis tshua muaj siab lossis lwm lub hom phiaj. Cov phab ntsa tuab ntawm cov yeeb nkab steel txuas tau muab faib ua cov yeeb nkab zoo tib yam galvanized steel yeeb nkab thiab cov yeeb nkab tuab galvanized steel yeeb nkab; Lub nozzle kawg yog muab faib ua cov tsis threaded galvanized steel yeeb nkab thiab threaded galvanized steel yeeb nkab. Qhov tshwj xeeb ntawm cov yeeb nkab steel yog qhia nyob rau hauv nominal txoj kab uas hla (mm), uas yog kwv yees tus nqi ntawm puab txoj kab uas hla. Nws yog kev cai siv ntiv tes, xws li 1/2, 3/4, 1, 2, thiab lwm yam.

2. zoo tib yam carbon steel hlau lub tes tsho (Yb / t5305-2006) yog cov yeeb nkab steel siv los tiv thaiv cov xov hlau hauv cov khoom siv hluav taws xob xws li kev lag luam thiab pej xeem cov tsev thiab kev teeb tsa ntawm cov tshuab thiab khoom siv.

3.Ncaj seam hluav taws xob welded steel yeeb nkab (GB / t13793-2008) yog cov yeeb nkab steel uas nws welded yog longitudinally parallel mus rau cov yeeb nkab steel. Rau cov qauv, feem ntau yog muab faib ua metric welded steel yeeb nkab, welded nyias-wall yeeb nkab, thiab lwm yam.

4.Kauv seam submerged arc welded steel yeeb nkab (SY / t5037-2000) rau kev sib kis ntawm cov kua dej siab yog ib qho kauv seam steel yeeb nkab siv rau kev xa cov kua dej siab, uas siv cov kub dov steel strip coil li yeeb nkab dawb paug, feem ntau sov kauv sib sau thiab ob sab. submerged arc vuam. Cov yeeb nkab steel muaj lub zog siab bearing muaj peev xwm thiab zoo vuam kev ua tau zoo. Tom qab ntau yam kev soj ntsuam nruj thiab kev sim, nws muaj kev nyab xeeb thiab txhim khu kev ntseeg siv.
