Xov Xwm - Qhov Loj ntawm Cov Yeeb Nkab Hlau Decoded: Lub Sijhawm, Phab Ntsa Thickness & Daim Ntawv Qhia Loj

Ib qho ntawm cov yam tsis meej pem tshaj plaws thaum yuav cov kav dej hlau yog qhov system sizing - OD, phab ntsa tuab, nominal loj, Schedule ... daim ntawv teev npe mus ntxiv. Kev qhia tsis raug tuaj yeem ncua koj qhov project lossis ua rau tsis ua haujlwm ntawm qhov chaw.

At Royal Steel Group, peb tau muab cov lus qhia ceev ceev no ua ke raws li ntau xyoo ntawm kev paub txog kev muab khoom thoob ntiaj teb. Nws npog cov yam tseem ceeb kom koj tuaj yeem teev cov kav dej kom raug thiab ntseeg siab.

Peb Qhov Tseem Ceeb ntawm Cov Yeeb Nkab Hlau

Txhua lub yeeb nkab tuaj yeem piav qhia nrog peb tus lej xwb:

Sab Nraud Txoj Kab uas hla (OD)- qhov dav sab nraud ntawm cov yeeb nkab

Phab ntsa tuab (WT)– phab ntsa yeeb nkab tuab npaum li cas

Ntev– feem ntau yog 6 m (20 ft) lossis 12 m (40 ft)

Nrog cov no, koj tuaj yeem xam qhov hnyav, lub peev xwm siab, thiab tus nqi ib 'meter' lossis 'foot'.

Daim Ntawv Qhia Qhov Loj ntawm Cov Yeeb Nkab Hlau (Daim Ntawv Qhia Loj)

Daim Ntawv Qhia Txog Lub Sij Hawm Yeeb Nkab hauv mm raws li hauv qab no, saib ntawm no rau Daim Ntawv Qhia Txog Lub Sij Hawm Yeeb Nkab hauv nti.

Cov Qauv Kev Lag Luam rau Qhov Loj ntawm Cov Yeeb Nkab

Muaj ob lub qauv tseem ceeb siv thoob ntiaj teb:

ASME B36.10M- npog qhov ntev ntawm cov kav dej carbon thiab alloy steel seamless thiab welded, rau kev pabcuam ib txwm, siab, thiab kub siab

ASME B36.19M- npog qhov loj ntawm cov yeeb nkab stainless hlau; feem ntau zoo ib yam li B36.10M, tab sis qee qhov tuab ntawm phab ntsa tau cim nrog "S" tom qab los qhia qhov txawv

Qhov Loj Nominal: NPS thiab DN

NPS (Qhov Loj ntawm Cov Yeeb Nkab Nominal)- lub npe nrov hauv North American, hauv nti.

Ib qho ntxiab uas feem ntau pom:NPS TSIS yog OD tiag tiag.Rau qhov loj me hauv qab NPS 12 (DN 300), qhov OD tiag tiag loj dua li tus lej nominal. Piv txwv li, NPS 4 yeeb nkab muaj qhov OD tiag tiag ntawm 4.5 nti, tsis yog 4 nti.

DN (Txoj kab uas hla nominal)- qhov sib npaug ntawm cov metric siv thoob ntiaj teb, hauv millimetres. Tus nqi DN yog ze rau, tab sis tsis yog qhov tseeb, lub cheeb sab hauv. Nws ua kom ntseeg tau tias cov kav dej thiab cov khoom siv nrog tib DN tuaj yeem hloov pauv tau.

Kev Hloov Pauv Ntawm NPS thiab DN:DN25 = NPS 1, DN50 = NPS 2, thiab lwm yam.

Cov lej teem sijhawm - "Qib" ntawm phab ntsa tuab

Teem sijhawm (luv ua Sch)yog ib tus lej uas sawv cev rau cov koob tuab ntawm phab ntsa - tsis yog tus nqi tuab ruaj khov.

Rau ib qho me me uas muab, tus lej Schedule siab dua, phab ntsa tuab dua thiab qhov ntsuas siab dua. Cov sijhawm feem ntau suav nrog Sch 5, 10, 20, 30, 40, 80, 120, thiab 160.

Vim li cas Sch 40 thiab Sch 80 thiaj li nrov?Vim tias lawv npog qhov tuab ntawm phab ntsa uas xav tau rau feem ntau ntawm cov ntawv thov kev lag luam. Lawv muaj nyob rau hauv ob qho tib si carbon steel (piv txwv li, API 5L, ASTM A106B) thiab stainless hlau (piv txwv li, ASTM A312 316L), yog li lawv yog cov khoom siv dav tshaj plaws thiab siv.

Cov Chav Kawm Qhov Hnyav (WGT)

Ua ntej lub sijhawm teem tseg los ua tus qauv, phab ntsa tuab tau muab faib ua pawg los ntawm qhov hnyav:

STD (Tus Qauv)

XS (Muaj zog heev)

XXS (Ob Chav Muaj Zog Ntxiv)

Cov chav kawm keeb kwm no sib raug rau qee tus lej Schedule - rau qhov sib npaug zoo sib xws, saib ASME B36.10 thiab B36.19.

Yuav Piav Qhia Txog Cov Yeeb Nkab Li Cas Kom Zoo

Ib qho ntawm cov hom ntawv hauv qab no yog siv tau, nyob ntawm seb koj nyiam lossis koj cheeb tsam ua li cas:

Hom ntawv	Piv txwv
OD × Phab Ntsa Thickness × Ntev	Φ88.9mm × 5.49mm × 6m
NPS × Lub Sijhawm	NPS 3″ × Sch 40
NPS × Chav Kawm Qhov Hnyav	NPS 3″ × STD
OD × Qhov hnyav ib chav ntev	3½″ × 16.8 phaus/ft

Royal Steel Groupmuab cov kav hlau tsis muaj qhov txuas thiab vuam raws li cov qauv API, ASTM, EN, thiab JIS. Yog tias koj muaj lus nug txog kev xaiv cov kav dej, thov hu rau peb pab neeg tshaj lij - peb nyob ntawm no los pab.
