Sch 40 Cov Qauv Yeeb Nkab - Cov Qauv Txheej Txheem Rau Huayang Erw thiab HFW Kav

Raws li tus kws ua txuj ci ntawm Hebei Huayang Steel Yeeb Nkab Co., Ltd. Rau peb cov khoom tseem ceeb -hluav taws xob tiv thaiv welded steel yeeb nkabthiab HFW Steel Yeeb Nkab{{0- SCH 40 tsis yog "loj lo cim"; Nws yog kev cog lus ntawm kev ua kom muaj zog, siab tsis kam, thiab tus nqi- ua hauj lwm zoo. Txawm tias cov neeg siv khoom lag luam yog sourcing rau cov kab sib xyaw Hauv tsab xov xwm no, peb yuav tawg SCH 40 tus yuam sij sab, piav txog li cas phab ntsa tuab yog engineed, thiab showcase li cas Huayang siv cov qauv rau ob qho tib sihlobthiabHFW Steel Yeeb Nkab{{0 {}} Thaum teb cov lus nug tseem ceeb liDab tsi yogERW YEEB NKABthiab txhais cov ntsiab lus zoo liERW cov yeeb nkab ntsiab lusthiabHFW lub ntsiab lus.

Dab tsi yog SCH 40 yeeb nkab? Lub hauv paus ntawm cov qauv yeeb nkab sizing

Ua ntej ntsev rau qhov ntev, cia pib nrog cov hauv paus:Dab tsi yog SCH 40 yeeb nkab?"SCH" (luv rau "lub sijhawm") yog lub ntiaj teb txheem uas txhais tau cov yeeb nkab phab ntsa tuab (nps nominal loj). Tsim kom tshem tawm tsis meej tawm thoob plaws kev lag luam, sch 40 nyob rau hauv lub "nruab nrab}} {}}}}} mpa rau cov roj av steel).

Ntawm Huaayang, peb tsim qauv Sci 40 kav rau peb tus qauv tseem ceeb, ua kom haum rau cheeb tsam thiab cov phiaj xwm kev xav tau:

ASTM A53: Rauhluav taws xob tiv thaiv welded steel yeeb nkabExported rau North America, kom tau raws li kev sib raug zoo nrog peb thiab Canadian Infrastrastructure.

GB / T 3091: Suav teb cov qauv rau peb lub tsevERW kav, siv hauv nroog dej, roj av, thiab cov dej ntws tawm.

API 5L: Thov rau pebHFW Steel Yeeb NkabRau cov roj thiab roj kis tau, qhov twg Sch 40 lub thickness sib ntsib nruab nrab - siab} cov kev xav tau.

Nws tseem tseem ceeb kom paub qhov txawv Sch 40 daim ntawv thov nyob rau hauv peb ob hom kab hlau tseem ceeb, raws li lawv cov txheej txheem tsim qauv duab yuav muaj qhov ntev li cas:

ERW cov yeeb nkab ntsiab lus: Cov Hluav Taws Xob Hluav Taws Xob Vuam, qhov qis - zaus (0.05% c) rau hauv cov kav dej thiab cov roj ntsha thiab fuses illes thiab fuses edges thiab fuses edges ntawm hluav taws xob tiv thaiv tshav kub. Peb lihluav taws xob tiv thaiv welded steel yeeb nkabHauv SCH 40 yog tsim los rau yoog thiab yooj yim ntawm kev teeb tsa - zoo meej rau cov phiaj xwm hauv nroog.

HFW lub ntsiab lus: High {{- zaus vuam, uas siv 300-500}} roj carbon stips (0.60% -0.60% rau cov kav dej. Nqaim thaum tshav kub -} cuam tshuam cheeb tsam ntawm HFW cia pebHFW Steel Yeeb NkabHauv kev kawm 40 tswj cov tuab, txawm rau loj- txoj kab uas hla.

2. Qauv 40 Cov Yeeb Nkab: Nominal loj vs. Kev ntsuas ntsuas tiag tiag (qhov tseem ceeb tshaj plaws)

Ib qho kev ua txhaum cai ntawm cov neeg siv khoom yog sib npaug "nominal loj" (piv txwv li, NPS 4) kom "txoj kab uas nyob rau hauv" tiag tiag. " Nyob rau hauv kev muaj tiag, nps yog keeb kwm hais txog- Cov kav dej thaum ntxov tau muaj npe rau lawv cov txheej txheem sab hauv (ID), tab sis cov qauv niaj hnub kho covSab Nraum Incha (OD)Rau kev sib xws, thaum phab ntsa tuab (thiab yog li id) sib txawv los ntawm kev teem sijhawm. Qhov txheej txheem no ua kom muaj Huayang's SCH 40 kav haum seamlessly nrog ntiaj teb fittings, flanges, thiab li qub.

2.1 Huayang's SCH 40 Cov Yeeb Nkab Daim Ntawv Qhia Dimension (Carbon SteelERW & HFW)

Hauv qab no yog lub rooj ntawm peb feem ntau tsim cov sch 40 qhov ntev, tshawb xyuas ntawm-} -} kev xeem sib xeem xeem. Cov no siv rau ob qho tib sihluav taws xob tiv thaiv welded steel yeeb nkab(Nps 1/2 "-12") thiabHFW Steel Yeeb Nkab(Nps 4 "-24"):

Nco tseg: HFW kav pib ntawm NPS 4 "Vim tias nruab nrab {1} {{{{{} {mmd thiab ± 12% thickness).

Ntawm Huaayang, peb siv tau qhov ntev no txhua hnub. Piv txwv li, peb tus lej 4 "hluav taws xob tiv thaiv welded steel yeeb nkabYog tshuaj xyuas nrog laser gauges thaum muaj ntau lawm -}}}} om deviates los ntawm ntau tshaj 0.3mm, tag nrho cov batch yog rov ua dua tshiab. Qhov no precision ua kom peb 2024 tus me nyuam mus rau Beijing lub nroog dej hauv nroog (10,000 tons ntawm 4 "ERW kav) haum rau lub sijhawm uas twb muaj lawm, txiav cov sijhawm teeb tsa los ntawm 20%.

Sch 40 Thiaj Thickness: Yuav ua li cas nws ua engineered rau lub zog thiab siab

Sch 40 lub phab ntsa tuab tsis yog tsis txaus ntseeg} Nws tau suav siv cov mis ua haujlwm siab, khoom siv zog ntau tshaj plaws, thiab kev nyab xeeb. Kev lag luam - Txheem kab zauv (siv los ntawm Huayang cov pab pawg engineering) yog:

T=(p × od) / (2 × × e + p)

Qhov twg:

T: Yuav tsum muaj phab ntsa tuab (hli)

P: MAXIMES UA HAUJ LWM UA HAUJ LWM (MPA) - feem ntau 1.6-10 MPa rau sch 40 Carbon Steel

Od: Cov yeeb nkab txheej ntawm lub taub (hli)

S: Cov kev ntxhov siab uas muaj kev ntxhov siab ntawm cov khoom (MPA) - 195 MPa rau tsawg {1} - carbon hfw steel

E: WELD sib koom tes ua ke - 0.85 rau ob lub ERW thiab HFW kav (qhia txog kev ntsuam xyuas ultrasonic)

Vim li cas Thickness nce nrog NPS loj

Cov kav dej loj yuav tsum tau tuab phab ntsa kom tsis txhob muaj qhov siab - qhov no yog lub cev tsis zoo. Piv txwv li:

Ib 2 "SCH 40 CHAB (XYOO)

Ib tug 12 "SCH 40 cov yeeb nkab (od 323.9mm) yuav tsum muaj 10.31mm Thickness rau lis cov khoom ntawm phab ntsa, xav tau cov khoom siv ntxiv.

Ntawm Huaayang, peb coj cov kauj ruam no txuas ntxiv los ntawm kev sib txuam nrog cov tuab. Rau pebhluav taws xob tiv thaiv welded steel yeeb nkab(Tsawg {{- @} {{{{{{{{{{{} Lub siab tuab) kom tswj tau siab.HFW Steel Yeeb Nkab(Nruab Nruab Nruab Nrab-} cov hlau carbon): nws cov kev ntxhov siab ntau dua (245 mpa} mpa} mpa) cia peb khaws cov tuab. Piv txwv li, 16 "SCH 40 HFW yeeb nkab tsuas xav tau 11.91 hli thickness los lis 8 mpa} - carbon erw.

Sch 40 Hauv ERW kav: Tsawg -} Cov Hlau Carbon Hlau Rau Kev Siv Hauv Nroog

Los teb cov lus nugdab tsi yog erw yeeb nkabnyob rau hauv cov ntsiab lus ntawm sch 40: pebhluav taws xob tiv thaiv welded steel yeeb nkabHauv SCH 40 yog tsim los ntawm tsawg-} cov hlau carbon steel (0.05% -0.25% c) thiab tsim los ntawm qis {zaus EMW vuam. Qhov kev sib xyaw ua ke no muab ob qhov txiaj ntsig tseem ceeb rau kev kawm 40 daim ntawv thov: ductility (rau kev teeb tsa yooj yim (zoo tagnrho rau cov phiaj xwm loj).
