Yuav ua li cas yog lub loj yeeb nkab?

Niaj hnub nimno kev lag luam ua cov kav dej ntawm txawv diameters uas yog siv nyob rau hauv ntau yam teb. Hlau-yob thiab ib tug me me txoj kab uas hla nruab nrab yog siv nyob rau hauv lub tsev ntawm ntau lub zos. Thiab cov khoom ntawm loj inch yog feem ntau siv nyob rau hauv hluav taws xob sib txuas lus thiab cov roj thiab cov nkev pipelines. Xaiv ntawm ib tug yeeb nkab inch yeeb nkab nyob rau hauv lub hom phiaj, thiab nyob rau nws kav ntev npaum thiab cov kev khiav hauj lwm tej yam kev mob.

hom

Tam sim no, loj-inch steel kav dej uas sib cais raws li txoj kev ntawm lawv cov lawm. Muaj ib-leeg, uas yog ua los ntawm steel ntawv los ntawm txoj kev tsis kam welding. Lawv muaj ib lub cheeb ntawm los ntawm 114 mus 530 hli.

Qhov thib ob hom ntawm cov yeeb nkab hu ua kauv. Lawv yog ua los ntawm dov hlau siv hluav taws xob arc welding. Lub npe muab ib lub tswv yim ntawm yuav ua li cas lub leeg nyob, uas qhov kawg khoom. Cov kab uas hla ntawm tej khoom yog nyob rau hauv ntau 159-820 hli.

Qhov thib peb hom yog cov loj tshaj plaws - nrog diameters xws li los ntawm 530 hli rau 1420 hli. Lawv yog cov lag luam muaj nyob nrog ib tug ib longitudinal ncaj leeg, uas yog arc welding.

Tsis tas li ntawd, nyob rau hauv lub muaj ntau lawm txheej txheem yuav tsum nqa npoo - trimming thiab deburring. Qhov no tej zaum yuav ua thiab kav tsis edgings.

daim ntawv thov

Qhov kev xaiv ntawm cov ntaub ntawv pw rau ntawm tsim theem ntawm ntau yam khoom. Txij li thaum nyob rau hauv kev tsim kho ntawm lub cev pipelines rau hydrocarbon feedstock, yuav siv loj inch kav. Yeeb Nkab 1420 hli tso cai rau kom tsim nyob rau hauv no conduit patency tsim nyog raw cov ntaub ntawv thiab, thiaj li, tus tsuas lub koom haum yuav tsis txhob cia buyer. Zoo ib yam li cov nqi yuav tsum los ntawm designers thiab me txoj kab uas hla cov hlab - 900, 920 los yog 1020 hli.

Nyob rau hauv qhov kev koom, kev tsim kho ntawm pipelines uas thauj tus raw khoom zoo suited raj 920 los yog 1200 hli. Qhov no yog vim hais tias xws kav muaj ntau compact thiab tsis dhau sawv tawm tsam lub nroog toj roob hauv pes (nrog rau lwm piping), thiab nyob rau hauv tus txheej txheem ntawm tso lub underground - koj xav tau ib tug qhov ntawm qhov tob (li no, yuav tsum tsawg ua hauj lwm tearing thiab backfilling ntawm trenches).

Tsis tas li ntawd nyob rau hauv localities steel yeeb nkab 920h12 los sis 1,000 hli yuav siv tau rau hauv vaj tse chaw (kav xa dej, kav dej phwj). Piv txwv li pro hloov rau steel kav ntawm cam khwb cia hlau kav 920h12 zoo sau ntawm no http://steel-snab.ru.

Plus, txawm deducting cov nuj nqis rau kev khawb, backfilling ntawm trenches, tus nqi ntawm neeg ua hauj lwm 'nyiaj ua hauj lwm, peb tes num ua hauj lwm, nws yog tseem ntau. Lawv nqi qis tshaj uas ntawm cam khwb cia hlau. Tab sis lub neej ntawm lub steel yeeb nkab yog qis dua hais tias ntawm cam khwb cia hlau counterparts. Tab sis muaj zog tshaj cam khwb cia hlau, steel - lawv yog cov tsis ntshai poob siab thiab yog li ntawd tsawg puas thaum lub sij hawm thauj mus los thiab tuav hauj lwm. Lwm zoo dua ntawm steel khoom ua ntej hlau nyob rau hauv lub vaj tse system - siab kuj mus corrosion.
