Cov Sijhawm Yeeb Nkab kho cov phab ntsa tuab: tus "tsav" ntawm daim id sib txawv

Kev cuam tshuam tseem ceeb thib ob yog:Rau qhov chaw ruaj khov nominal kab zauv (thiab tsau OD), ID txo qis li cov khoom ntim cov khoom lag luam (thiab phab ntsa tuab) nce ntxivCov. Cov tsheb tawg (Sch) yog qhov sib piv ntawm phab ntsa tuab dua), uas nyob hauv qhov chaw siab dua (los ntawm kev coj ntau qhov chaw hauv sab hauv tsau

Qhov kev sib cuam tshuam no tsim ib qho "kev ua lag luam tawm" ntawm qhov siab tsis kam thiab ntws mus rau txhua hnub ntawm Huaayang, raws li cov yeeb nkab hom:

ERW kav: Cov sijhawm teem sijhawm qis dua, tus lej loj rau cov dej ntws tawm

Dab tsi yog erw yeeb nkabHauv kev sib cuam tshuam no? ERW (ERW cov yeeb nkab ntsiab lus: Cov Hluav Taws Xob Hluav Taws Xob Vuam) Cov kav dej yog tsim los ntawm tsawg- cov hlau carbon (0.05% c) thiab feem ntau tsim hauv Daws 20-40. Lawv lub sijhawm qis dua txhais tau tias thinner phab ntsa thiab tus lej loj}}}}} qhov nruab nrab qhov twg ntws (dictated los ntawm id) yog qhov tseem ceeb.

Piv txwv: Peb tus lej 6 AFF tus kab yas muaj ib qho od ntawm 168.3mm, Phab Ntsa Thickness ntawm 7.11mm, thiab ID ntawm 154.08mm. Qhov no loj tau muab tus nqi txaus ntawm ~ 300 m³ / h (rau dej), ua kom nws zoo tag nrho rau cov neeg siv khoom 100 tsis tas

HFW Kav: Cov sijhawm tsheb siab dua, tus lej me rau qhov ua tau zoo siab

HFW lub ntsiab lus(High {- zaus vuam) kav siv nruab nrab-}% c) thiab feem ntau yog ua hauv sch 40-80. Lawv lub caij nyoog siab dua txhais tau tias tuab ntawm phab ntsa thiab me ids -}} ua ntej tshaj plaws siab.

Piv txwv li: Peb tus lej 6 DAM 80 HFW YEEB MUAJ tib OD (168.3 hli) raws li lub ERW variant tab sis ib tug tuab phab ntsa (107.98mm). Thaum nws txaus tus nqi ntws mus rau ~ 270 m³ / h, nws tuaj yeem tiv thaiv 12 {{9 {9} {9 {9 {9 {9 {9 {9 {9 {9 {9 {9} {9} {9} {9} {9} {9} {9} {9} {9} {9} {9} {9} {9} {9} {9} {{9} {9} {9} {9} {9} {9} {9} {9} {9} {9} {9} {9} {9} {9} {9} {9} {9} {9} {9}-

At Huayang, we use this interaction to guide client choices: a Jiangsu chemical plant needing both low-pressure drainage and high-pressure steam lines chose NPS 6 SCH 20 ERW pipes (ID 157.12mm) for drainage and NPS 6 SCH 80 HFW pipes (ID 147.98mm) for steam-optimizing both flow and pressure xav tau.
